Contouring Pre-Sintered Zirconia: The Key To Achieving World Class Esthetics - Jack Marrano, CDT

so thank you guys for coming this is incredible this is probably the biggest hands-on demonstration that I've ever seen or done hands-on demonstrations to me are so close to my heart because I get to work with you guys face-to-face one-on-one we talked about your labs we talked about your doctors we talked about what you're experiencing and it's really normally a very intimate setting and that's what I love about it so much when I actually seen this setup in the format for how we're gonna do this today I almost had a heart attack so it's gonna work really well we got a camera set up right here now I'm gonna go through a whole bunch of slides and kind of show you first what we're gonna talk about and actually do in the hands-on and then I'm gonna roll right into the hands-on and you guys let's try to keep it close let's try to keep it intimate ask questions kind of you know throw your hand up if you if you have a question and see if I can answer that for you to help you out we're gonna talk about green stages or cone ian is one of the most important aspects of working with zirconia especially in full arch full mouth hands down 100% somebody asked me recently it was actually Kate sitting right here at absolute dental what is the one thing that I would attribute to my success over the years and I would say a hundred percent hands down period contour contour I remember years back an article by Aki Yoshida and I was a big fan big fan still am a big fan today and he did an article where he took a single central and he layered you know 14 powders in it and I mean it was remarkable but the contour was off the surface texture was off then at me it was off everything was off put it in the mouth and it stuck out like a sore thumb he took that same central and then redid it three shades off but now the contour and now the surface texture and now they Anatomy and it disappeared in the mouth for all of my years I'll never forget that and at that point because I'm a real true dental geek just like all you guys and nerd out over this stuff I was hooked I was absolutely obsessed when we're looking at zirconia and the mills and the design software and the designers will get you 90% there at that point it's your job to take it to the next level this morning when I was with me oh I was shown a lot of examples of zirconia that had not been green stage finished and the difference you can make just by spending a few minutes on it prior to sintering okay and you definitely don't want to do it post Center okay you definitely want to do it pre Center we're going to talk about that today I have a ton of zirconia in right now we're actually cut it live and again this is this is the biggest hands-on I've ever done so I would from my heart thank all of you for being here today this is awesome so let's go ahead and get started Chicago 2020 that's insane that's absolutely nuts and when I think of Chicago of course I think of this still after all these years they have not moved the meeting either during the year or the location to warm it up a little bit although this week hasn't been necessarily too bad and green stage finishing the zirconia that is by far the most important thing that you can do to take your zirconia to the next level the quality of zirconia obviously we already know we're using Argan zirconia and zirconias are not all created equal and I'm not just talking about the translucency I'm not just talking about the strength I'm talking about the quality of the powders that they use it produces their Konya toe so which aragon still uses and we all know is still considered the best ur Konya that you can make your material out of isn't always the zirconia that's being used today so you definitely want to keep an eye on that so quality is our Konya we already got that checked because you're all sitting here and also a green stage finishing this is an example of there's no green stage finishing but also they try to kick it up a notch by layering it and I want to tell you guys and you guys have seen me speaker you guys that known me and see me do this before I don't do this and in please do not take this the wrong way I've been incredibly lucky in my career I've been incredibly blessed in my career I gret have a great family that's behind me and I've got to work with these you know world-renowned world-class clinicians that's why I'm losing a lot of my hair that's why I have a lot of gray hairs coming in and what's left but I don't put this up there to poke at the technician that made it I just want to educate you guys it's easier for technicians and the way we learn to see what not to do and then to see what to do to register in our minds that's how we learn we are let's I heard it once best describe that technicians are creatives right and our mind works that way so I put these images up not because I'm saying look at how this looks and look at how much better mine is I'm not trying to give you that sense I just want to take a look at a couple cases and to show you the differences so that you understand the importance this case right here interestingly enough and once you post it on the Internet it's there for life so just keep that in mind but this gentleman got nine likes we'll talk about the finishing that he did but not only the finishing there's there's a lot this could be I could take that hybrid right there and that could be a one-hour lecture let's start with the green stage finishing there was none that came out of the mill and the sprues were cut off and it was sintered and then let's talk about the distal extensions they're way too great let's talk about the flanges there's no way the patient can clean that and those are the kind of things that we're gonna avoid when you do your restorations your restorations gonna look different than mine but I would like to see the certain keys or trends and what I do in my zirconia arch is that you guys can actually go ahead and do yourself these are the birds I use so this is my third lecture today I still have my voice I'm doing pretty good curious to see how it goes tomorrow and I've used this same slide in all three and this is the same slide if you've seen me do this before that I've been using for years that's because it has not changed I don't use I don't overcomplicate anything in a laboratory I keep it incredibly simple it's very very important to me so when I have my birds and I have my diamonds I don't have a lot of them that do very little I have very few of them that accomplish a lot I don't have a rubber wheel that I bump with this and then I take it off and say oh no I have another one that I use this for and then I take that one off and but wait I have one more that I go ahead and hit it like this that's basically what I use in the laboratory and I'll use these for green stage finishing a zirconia I'll use these for PMMA I'll use these for lithium Netsilik it doesn't matter what I have it's gonna be the same lineup the only one that's not missing from this photo is one right here it's the exact same carbide it's gonna be the h2 93 II all of these come from brass ler and it's gonna be the same one but it's gonna be a taper at the end that's probably the one that I use the most and then we're gonna have the scotch brite we're gonna have the blue dial light and we're gonna have to run for a brilliant disc I've been using the rim for brilliant discs for years and sometimes I get some feedback yeah I tried them and I didn't like am i broken they have a ton of flex to them but if you do over flex them they will break I it cuts zirconia incredibly smooth it contours ricany incredibly smooth same thing I'll use that on PMMA I would use that on layered ceramics I don't do and even anymore but I would use it I could use that to top off and knock off the top of a Thai base so they're they're really really good and this is basically if you came to my bench that's what you're gonna find you're also gonna find number 9 short stiff okay the short being the key part of that and the reason why is if you use the regular of the long and you go ahead and polish zirconia all the bristles are gonna get in here sure is gonna feel like you just got a fresh haircut irritate the hell out of you at least it does me so short stiff is the key or a goat hair works very nicely there's the goat hair and also this product so you're all here at LMT 2020 and this was just released by harvest this is harvest ensel's new diamond paste for zirconia or lithium - silica and they're gonna be honest with you guys and being a former Marine and my wife is here this is her first Chicago midwinter she thinks were absolutely all nuts she's heard the stories but now she's actually living it she's like this is insane so I turned 40 a few years ago don't actually want to say how old I am except I'm trying to fight it but I turned 40 a couple years ago and realized that I was not the bulletproof former Marine that I believed I was Dreamz van artist sitting areas Conrad's business partner and I really do love him to death because he's been the first person ever in my life that said put on a mask because I realized I got to that age of 40 I hurt myself sleeping now okay I wake up in the morning and I have a whole new body pain that was not there yesterday so I started to take that into consideration and the polish should be used I've been fortunate to probably process more zirconia hybrids than than anybody in North America and a lot of times early on years there was a ton of polishing that was happening the polishes that we have polished extremely well but they're very very dusty and you all know what I'm talking about I would be coated on my glasses it would be covering my shirt and you know it's in my lungs I'm breathing it don't have a mask that's terrible do not do that juries is sitting right there he'll tell you do not do that he tells me every day what we noticed was speed polished and I got this early on I was able to give it to the technicians as the laboratory is it is completely dust free so there's none of that crap it's not lying all over your bench it's not thick on top of your shirts not all over your glasses is completely dust free and I would actually probably say that it polishes faster than the current polishes that we're all using right now that in the fact that it's water soluble so harvest dental they're not here right now they probably don't even know I have that slide up but they are launching it at this LMT so it's very very exciting for them and I am very grateful there for them for developing this product that's an example of Polish to Konya now this used to be the old standard and we kind of be back that whole glazed thing and polished and this and that but I still polish the intaglio side of hybrid restorations the reason why is because it is the slickest this is the slickest kind of treatment you can do to the zirconia on a hybrid so that you don't get all the crap sticking out I've had guys take these out of the mouths of year and a half later and although we've designed them very hygienic there was some garbage under there and they took their finger and went like this and it came right off so you definitely want to polish the underside of your hybrids if I'm polishing that's what I'm using because I'm getting that result and of course multi-layer zirconia came out and Arjun has a fantastic one and this is kind of beat the death layering it doesn't matter if it's a single central doesn't matter if it's an eight and nine you can virtually do anything with this material it's absolutely fantastic it's very shade correct they got all the shades and they did a wonderful job developing it and I've been a big fan of multi-layer zirconia but I have two zirconia as I use in lab I'm gonna use the multi layers of Konya this is a perfect example single central for years I used to do this if a manufacturer came out with a product and they said don't use in the interior what was the first thing I did I used it in the anterior and then I showed it to him and said look what I did with the product that you said not to put in the anterior this is the same example but this is recommended for answer use single units and you can see this was done with dr. Chris bar which is a University of Iowa and that is a number eight and you can't really beat that that's not layered that's monolithic multi-layered zirconia it's not layered in the traditional sense ideas Canada bring this up this was a big part of my a CP lecture educating the process the prostatitis from that side down because I was talking with dr. Ludlow and he's an incredible clinical researcher I mean probably the best in the world right now and we were both early adopters and pioneers in zirconia and we said is our cornea that time had lots of bad properties and a couple of good ones one of the good ones was it masked out anything nasty behind it okay we never thought we would see the day when we can look back and say Zuko Nia's too translucent it's too good it's too aesthetic and that's where we're at it has lost the property to mask ideas CAD which is a very strange company has white plus and a lot of you are probably using it or maybe just hearing about it it's an exceptional product in the first time I heard about it I got to give him credit cuz one time he told me I didn't he got really mad but the first time I heard about it was my younger brother is a technician and he says the greatest thing ever I'm gonna picking zirconia and my response was that's the stupidest thing I've ever heard of in my life because the last thing we want to do is opaque Zehra Konya that being said we use it every single day in the laboratory today because it's gonna block out our custom abutments it's gonna block out our dark stumps using the Arjun STM L okay because it is as aesthetic and translucent as Emacs now and it's gonna look like that and so when you see it and you want to kind of you definitely want to let your clinicians know if you're about to use it you can notice in this image and that we did not lose any of the aesthetics of the zirconia it did not o pacify the zirconia itself it did opacifier inside you can see how bright it is it looks like thick white out it doesn't change the fit or anything like that but it is ugly as hell and a good friend of mine again prosthodontist the only kind of friends that I have and he called me up and he was like a Navy sailor in a bar he just flipped out I it is not safe for lecture for me to even repeat everything he was calling me and he said what the hell is wrong with your QC I said I've got my crowns and they got all this white well said remember we talked about that and I put that in there and this is why and these are oh okay a couple days later he said they sent me it's actually said case was beautiful so you definitely want to let them know he said because he said I tried grinding it out I tried steaming it out I tried scrubbing it out then it would not come out in it won't but that's what we're using now because the zirconia has become so esthetic it has lost the ability to mask custom abutments dark stumps here's the case with dr. Ludlow again this was an as n tow case so basically a whole surgical kit with custom abutments in a box and he went ahead and delivered this that is Arjun st multi-layer it's out there in the hall that is basically staying glazed to the left is his Provisionals which he did an exceptional job on and then the eight and nine in the st AML i used the white plus to block out the custom abutments behind because then otherwise what you've seen is and what you will can you will start to see if you're using material is you'll get a lot of calls it was great until i cemented it and then it went gray because it will gray out just like that green stage finishing on smaller cases so if it's a single unit molar i don't do it we're a kind of a boutique lab yes sir I still go dead-on to the shade and and also actually a good point um I have a laser pointer in my bag I'm gonna break it out if you look at that that molar it's very important I stay a millimeter away from the margins and the reason why is you will start to brighten up right at the margin area so I stay a millimeter away from the margin you don't need it down there you might think you do but you definitely don't you see how far away I am from the margin and you can see how much it's absorbed into the material but if you take it down to the margin you are not gonna be able to get that to cover up okay you can try staining it till you're blue in the face and it is gonna be this ugly white line let me tell you something be incredibly careful with this material because it is unforgiving and you won't know till after you censor it if you've screwed it up so green stage finishing if I have a single unit molar we you know everybody's got to do production nobody likes to call it that no matter what but that's what we got to do to eat and so if I have a single unit of molar I'm not so necessarily concerned about it to central's aesthetic zone seven through ten six through 11 anterior bridges I'm green stage finishing okay I'm gonna go ahead and put it in now so I don't have to do it later and that's kind of what this is you know kind of very simple nothing fancy full arch zirconia on the other hand has a whole nother ballgame Arjen ht+ this is obviously the zirconia that I used and I've been using for quite some time obviously for why obviously 1250 MPA and we're able to get aesthetics like this so again back to using quality zirconia followers and following green stage finishing this is dr. sherry Ginsburg UIC Graduate prosthodontics and I don't think it really you know we're continuing to push the envelope but that's a fantastic result and that's a monolithic result with monolithic occlusion and no layering this case right here dr. Ludlow same thing that's gonna be full arch zirconium monolithic ht+ stain and glazed mio pink for the gingival ceramics okay in this case done by Yong su Kim Yong su is here actually I think he's here right now haha there he is haha Yong su Kim is live right there Yong soo did this case with dr. Elsa fatty from U of F thank you sir and it's an amazing amazing case and these are the level of aesthetics that were able to achieve with HD plus and green stage finishing Yong su did not get this out of the mill and center it he got this out of the mill and he did his contouring at that time in green stage and then he censored it and that gave him the ability to achieve these lifelike results very very important I want to point this out if I'm a stickler for anything an answer your a case obviously we've known or learned that's the most important 8 to 10 millimeters in dentistry the midline after that let's look at some other areas gingival embrasures incredibly importance incredibly important that will make all the world's a difference on your cases ok and so it's very very important now I get asked a question if I have a screw axis hold right behind that gingival embrasure now I have an implant right behind that genital embrasure which could happen no I do not cut it in because I'm not willing to compromise the restoration to get the depth all right so that's very very important to keep in mind don't compromise your your your zerk to try to dig it in deep if there's a screw access hole back there if there's an implant back there just leave it alone I don't even go near I don't even separate it you won't notice the difference pressing the wrong clicker sorry I'm dual wielding clickers right now again dr. berry Goldenberg this is an early on me Oh ht+ case that I did with him denture on top Zurich Oni Abeyta surprise Arjun is probably looking at me like right now what are you talking about ah but I would love to share this with you guys [Music] HTML that is awesome I am looking for the ultimate who's favored 11 I am looking for the ultimate hybrid zirconia and I got to tell you guys this is it I do not prescribe to a three y5y zorco neo with crazy demarcation or anything like that I don't want to end up in the process of having to nest my restoration with my posterior quads in straight 5y now there's anything wrong with 5y but if I'm working with full large Dirk I want max strength this is an all credit and kudos to the team at Argan the remarkable job they've done so this is version 1 and Jeff is looking at me right now and he's like I can't believe you have that up they're looking at and I'm gonna I'm gonna kind of put them on the spot right now a little bit with everybody here looking at a full release pylab de West Jeff close to it ballpark fully launched in June this is multi layered zirconia in Jeff and Paul Cascone have been have literally been burning the midnight oil in a working day and night to develop this product the beauty about this product and you can see this is like version 1.0 right we're still working on it working on the formations working on the recipes jeff says in me i cut case out of it and i give them the feedback you could already see the gradient and then size the ledge but the best part about it is from here to here it is solid for why zirconia so I don't have to worry about tipping into weaker area on clicker I want to show this case real quick before we start cutting the zerk and again talking about some of the same things that we've been talking about this case was and I gotta give him credit dr. James piezo at UIC grad profs did this case with him sent this case to him patient cancelled and I talked to him Tuesday when I was at UIC and I told him I said if you can get the patient in I speak at the ACP at 3:00 I will absolutely positively make sure I put that on the screen and literally he sent me the email at 12:00 he had just he had just delivered it so it's really we're awesome we'll get to see the case is it's already this is how it should go setups there's gonna be a prototype or a provisional in the middle Sura Konya centered when you look at that look at this aura Konya so very very important what do I have opened gingerol embrasures open incised embrasures this is scre access hole what did I not do I did not chase it or cut it we're gonna cut into it I just leave it I just go everywhere around except for there you can see how deep those are compared to that area we'll go ahead and center it wrong and that's the result we're gonna get that's going to be delivered and kudos to him he did an incredible job he's an excellent clinician in and and I honestly guys I don't I don't think it gets much better than that we were going in contour out of the mill green stage finishing again get very very deep in these areas we're talking about green stage finishing and I said it this morning and a couple people chuckled when you're working on it you want to exaggerate it okay because if you didn't exaggerate it and you got it to where you think you like it and then you Center it you may probably or I would probably guarantee be very disappointed so when you exaggerate it and you go a little bit more and you feel uncomfortable and you say this is too much Center it because I'll probably guarantee you it's going to come out and it's going to come out perfect because remember it's gonna shrink so everything you're doing at this point is magnified so go a little bit deeper be a little bit more intense with your Anatomy you could be a little bit more aggressive with your Anatomy and really that's awesome I don't know what they're doing over there but I'd love to see it that's hysterical that's great so is it it kind of plays well I don't even have to talk anymore ladies and gentlemen this is work it's really good look at all right so right here you're gonna see I have some tertiary anatomy in there you could totally put that in all of yours we'll look come this is great all of yours will look completely different than mine and that's okay because we each have our own style we each have our own signature but I want I want you to burn into your mind the key takeaways again what are we looking at in this case open gingival embrasures open incisal embrasures we have tertiary anatomy we have secondary anatomy we have primary anatomy the sky's the limit and this is where you really want to be an artist this is where you express artistic liberties is right now in this face okay and that's that's where if you follow these rules so here gingival embrasure and sisal and brazier most important 8 to 10 millimeters in dentistry if you do that I can promise you you're gonna you're going to step up your game and then here we go we're going to walk through this one same thing green stage finishing I got some tooth dimples on here right here it was funny we photographed one case in Conor it's like you know I don't know I probably take that out or something it was spot fixed I'm like no I put that in there it's a tooth dimple it's supposed to be there here's what it looks like centered again another example of early beta HTML you can see the gradients in the incisal and we'll go ahead and apply some Mayo so what we're gonna do and this is this is how you can get a hold of us social media wise kind of watch where we're always at and what we're doing I'm gonna step down over here and I'm going to back this up a little bit and we are going to they turn my clicker off let's go that one so I'm going to bounce between the camera and this image so that we can kind of correlate what I'm doing here with what's up on the screen and I'm gonna go ahead and kind of cue the the guys in the back and AV to let them see that all right so let me get started all right first of all because I'm old let me strap these on now we're ready for action and I'll kind of show you what we got so in the box is gonna be some of the tools that we've already been talking about we're gonna have the scotch-brite we're gonna have the Daiya lights or the Renford brilliant disc here's the dilate right here we're gonna have our brushes so our short stiff and our goat hair and here's the taper that I was telling you guys about actually I got three of them because I never want to be unprepared but you can kind of see the difference so here's the round right here see here's around right here and then here's the tapers alright and we're gonna have the 8:42 are mmm there's gonna be a flame and just a smaller taper and that's basically the lineup I'm gonna use for everything we're gonna do we're gonna have I do these Jeff actually asked the bottom so these are something that I set up for education it's going to be a six through 11 but they're kind of cool because they kind of stand on top of the bench they got a little tail on the end of them so you could hold them when you go to do ceramic standing glazing and we're going to do these this is gonna be your your basic let's say 6 through 11 it's kind of cooled or rotated is for education purposes so we could do something a little bit more cooler with the teeth instead of you know kind of straighter same thing here if you look at this this is gonna be more of our hybrid restoration so let me sorry guys this is live TV find the gas pedal alright and we are gonna find vacuum ah ready haha now we're in action hi so let me see let's do right here I'm gonna focus me it's very good huh look good is our focus actually it's a little bit oh alright how about that everybody liked it alright let's make this happen so first things we're gonna do I do everything in order you can ask my wife or anybody's had dinner with me Conrad injuries if I go to a restaurant and I have a steak and I have Brussels sprouts and maybe a scallop I eat the Brussels sprouts then I need to scallop the night the steak I don't kind of do go-betweens it freaks me out if I have fast food I eat all of the fries first and then I have the burger and then I drink the drink which my wife is very much a bite of a fry and a bite of a burger a type of lady so we're very much different in that sense but I make teeth exactly the way I eat which is kind of funny so first we're going to obviously remove the sprues let me see what I got I'm gonna kind of cherry pick my favorite one and these are all these are gonna be all milled out in Roland and so you're gonna get each mill not all Mills mill the same but I don't think at this point we really have bad Mills so I just cranked up the RPMs as high as they will go the faster that you cut zircon eeeh the smoother and less chippie it'll cut it was kind of scary when people see me do it I kind of have a lead foot I hit the gas like that and I just ripping with the handpiece that's normally the speed I'll be at when I'm doing something like this so I just cranked up the gas let me say all right now we're cruising and we'll go ahead and cut this off here forget some of that milling feedback off and remove the sprues this is very simple I really needed me to teach you that so now let's take a look at it you can see we have our tooth forms and generally kind of our gingiva the way that we would want it but it's not complete it's not done this is not where we want to go ahead and Center at this point now we want to go ahead and accentuate everything and bring out the design that we know we had prior to it going to the mill so first we are going to go to the Renford disk I'm going to keep it kind of long here and I'm going to do my most important cut right there over there and they over there that's my incisal and brazier cut okay now I'm gonna go ahead and bring it down and I'm just gonna take it straight down just like that now what you've created if we look from the incisal edge do you see how its square like that it goes I'm gonna draw kind of on the countertop but it goes straight out and over right that very sharp angle that's there that's not supposed to be there that's a defective me actually cutting into it so now we're gonna go ahead and properly contour this tooth by rolling that hard edge over there you go you can see it sorry I see it in there myself see the material I'm number eight still attached in the material on number nine removed that's basically what I'm looking for I'm not looking at the teeth I'm not looking at six through 11 I'm just concentrating on that right now so um singling out the tree in the forest and then I'll go back and look at everything as a whole so if I go off-camera you guys make sure you yell at me spin this around [Music] and notice that I did all of my cuts in one direction then spun around and now I'm going backwards I don't do this and then flip it around and do this and just work on this number 10 because it's very inefficient so I'm just opening up my embrasure so I'll open them up all in a one direction and then I'll come back and open them up all the other direction kinda like that now I'm gonna leave this other side so you could see the difference between what we do over here and what we do over there if you want to dust it off I get these cheap brushes from the craft store they're basically like a stippling brush and they will not damage your zirconia or your margins and you can kind of just take it brush it off like this so let's take a look at where we're at I'm not worried about anything else other than just creating those right now once we've done that I will switch back to let's say our flame and these are new they're all fairly new because I just taught a course and there's nothing wrong with them being new but I generally like them worn out a little bit because they're less scratchy if that makes sense so we're just going to go over them clean them up a bit kind of like that it doesn't it really doesn't take that much I definitely do not like that okay now to the fun part surface texture and Anatomy really the sky's the limit um and in this there's unlimited possibilities let's take a look at will do the central lateral and cuspid this is where you make your I mean for lack of a better term your own mark right this is gonna be your service sector your Anatomy your signature and there's we know primary secondary and tertiary it's the depth and how aggressive you place any one of those in the length that you can make this look like an endless combination so if we look right here on the central we are going to do a narrow one and then wide one okay on the lateral laterals only have one it's going to start wide at the top and then narrow down right there in the cuspid and on the distal it's gonna be wider now the interesting part about this is you can make this deeper or not and you can keep this length here or you could take it all the way the length of the tooth or you could take it halfway or anywhere in between choice is completely up to you at that point the lateral laterals only have one keep that in mind because a lot of times I'll see laterals with two and only has one this is your primary Anatomy your primary depressions I don't often put secondary a lot of times I'll go ahead and completely skip it and that's because when you get the secondary you're really starting to hollow out right in here and then right in here and on a cuspid secondary will come up like this and it'll come down like that so usually I'll put primary and then I'll add tertiary and tertiary there's several different examples you do vertical you do a horizontal broad horizontal fine stippling tooth dimples my favorite so I'm gonna take this this is the flame and I'm gonna push it I'm using the fat part and I'm gonna drive it down that's the movement that I'm gonna make and I'm gonna do it here and then drive it down it's very very quick so I'm gonna try to slow it down you don't want it to be too mechanical you want it more organic you don't want it to look deliberate kind of like that okay now I'm going to come over here to the lateral same thing big push and over here to the cuspid all right now see where we're at you can see there are other side and you can make this as smooth as you want as aggressive as you want it's your restoration you know your doctor you know your patient and this is just what's possible the kind of the order that I go in to do it when I'm going to here am i off you guys see we'll go ahead this is central up they'll come over a lateral same thing I'll do a little vertical there we go do a little vertical kind of developmental groove laterals are my favorite tooth in the mouth the kind of the sexy tooth I look like that well let's do our cuspid listen gas you can see here kind of our little developmental groove that I just put in like that now we'll get you and you know you can add let's see here if you want to add kind of kind of a cool crack line gotta bring that down it's kind of cool and it is very very aggressive but you can see where we've gone from clean that up on the distal of the cuspid so we'll shoot up but I'm definitely not changing the tooth contour or anything like that I'm working with what I have and we'll put some tertiary in there right now but you can see where we're at now and where we were that's it alright let's put in some tertiary and then we'll get down to the gingiva and then we're gonna do something really cool so you want to see this so a couple different tertiaries you can do stippling you can do kind of large horizontal so let's do this tooth dimple super cool put it in like that pull it out to temple a lot of times you'll see I'm just tapping it across like that let me brush it off so you can see it and then I'm gonna kind of go back and forth that's going to give you a little crosshatch pattern and then there's going to be you know kind of fine horizontal striations are gonna be broad horizontal striations I change the side I might put the 8:42 are on for this like that how are we looking on time weird good now see that's right on the centrioles a little crazy right there I'm just gonna pull that right back out that's pretty good let's do our incisal edges sighs the ledges are really really cool we're gonna wear them down when I do it I don't want to shorten the tooth I don't want to change any of the lengths but I do want to wear it on the incisal edge properly so I'll take a black pencil see how I marked the most facial point of the in size of ledge I do like that kind of like that now I'm going to take that rubber wheel it's it's really important when you work on contour that you'll figure out that what you do on the lingual absolutely 100% affects what you have on the facial okay now we'll do somewhere four sets and where if the sets are cool on the cuspid it's a push-pull so on a cuspid it's gonna be very much you'll see commonly a teardrop design like that all right the way you get that is I'm going to take this 8:42 are I'm gonna push it down there and I'm gonna peel it back up towards me like this with this motion and that's gonna give me my deep spot and then fade it out into shallow if I got it you can kind of see the tear drop shape in there now and for the other ones we'll use just the round taper we'll dig it in here deep and that's gonna give us our coolant war in sighs allege now we'll go ahead and do the gingiva and the gingiva I just rough contour you can spend as much or as little time as you want on the gingiva but if I'm applying my gingival ceramics my meal all of that surface texture and all of that anatomy is gonna come from the ceramic itself so I'm just gonna give myself a nice base to apply it to take off some of some of the junk on here all right leave our ginger little cups kind of like that and I'm gonna take this flame and kind of dig it in a little bit deeper and now we'll kind of finish it off and I'll show you how we'll clean it up at the end because we have new diamonds they're very scratchy more scratchy than I would like so there's a way we're gonna fix that and clean that up I'm just putting a little bit in there it's not choppy all right so you can see where we were and now we'll we've come to it's just not even a lot added you can go ahead and you can get a little bit more separation between your zirconia gingiva and your tooth right in here and they look a little bit more Scratchy there is a difference between service sexual anatomy and what I call noise remnants of a very coarse diamond so I'm gonna show you guys how to take that off we're gonna do that with the scotch-brite those of you that have used this will know exactly what this does so I'm gonna hit it basically on the mesial and distal kind of right up the middle but very very lightly and that's gonna take off kind of the garbage that I don't want there very lightly all right that's where we were this whirlwind - to my ginger embrasures we can go ahead and add papilla czar interesting really they're they're not Enys they're out ease but I will are there there any is there not Audi's but I will make them and howdy so sometimes I will do something that is not true to nature but it makes it look good that's kind of what happens here there we go okay let me sexy it up real quick for a second okay all right that will work sorry juries I did not have a mask but I blew out the whole entire time I swear all right who's got us injuring furnace youngster you don't count all right take that home and match my side okay and I don't know what that is but I'm gonna come up here how we looking for time Jeff what time are we done three yeah three all right so we're running short on time I'm gonna rip through some normal teeth like a six through 11 case so you guys could see me do that but what I want you guys to do is go home you don't start salts are either okay well we'll just take some of mr. Lothrop's time all right all right all right let me start from the back I would throw them but there's urk it's kind of like t-shirts all right who's not in the same lab I gotta get way there's a lady down there you know come come here I got to kind of spread them out all right and I don't know what these are so surprised when you Center them they may be beta-tested Zurich they may be regular ht+ it'll be a nice surprise when you get them out thank you courtesy of mr. Luthor oh yeah call are good for centering instructions so I don't know if you guys ever seen this as years ago but I pre infiltrate stains giant teeth it was really really cool it's because it was so small nobody could ever see it if I was trying to do it but they were big they were like this big and I poured him out a plaster and I had to warn everybody believe it or not because they're like what do I Center this on I'm like do not put that in your sintering oven please it's plaster so but no that is actual zerk so you can cook it let's take a look at this which is gonna be a little bit easier it's a little bit smaller obviously our teeth are severely rotated which we can get away with because right now in a demo we can do whatever we want Bob the dentist probably will not like that with Sally the patient I don't actually know a bob or Sally throw on my glasses so I could see first cut our sprues off as normal this you're going to get to be able to see me go through the arch form because we will do all six on this [Music] and I'll show you guys I mean I'm sure a lot of you guys have used those Scotch braids but if you haven't I'm gonna trash the backside of this restoration you can see what they'll really do so here we go let's kind of go real-time on this one I can make sure that I'm on the camera so you can see it years ago I was doing this and the laboratory I was consulting at had an espresso machine in the lab whoa nice right that's what I said so we were in no rush to get started and I love espresso so we were a couple of cups in before we finally got to the part that we're actually gonna start making teeth but when I started working on the case we're actually back then we were layering ceramics I was like this I looked like a recovering addict who's terrible so bad and it's funny every once in a while you'll see its skip like it has right here I generally don't even worry about that because when you Center it again talking about what we're seeing right now is exaggerated because it's larger that probably is not going to show up and I'm just pulling off that sharp edge okay it's kind of where we're at see there's a little remnant right there we'll go ahead and take that off a little bit more over here all right so let's clean up the teeth Oh we gas am i off I said all right so now let's go ahead and replay our surface sexual anatomy which is going to be right here so central your first one and then your larger one first one and then your larger one and first one let me guess now those of you that have a very keen eye will have noticed that we have lost some of our restoration we have a casualty I foolishly cut the manifold off of the back of these knowing that I designed them just for fun and think that we would have actually lost them but we did we lost some of soldiers down here go ahead and do all right you know bridges turn into a three in it split know that I can teach you I do all day long that's easy guys let's see here so I'm going to wear down again our incisal edges like that and we'll go ahead and again kind of go in the corners we're going to go deep and pull it when I connect them and let's spend with the scotch-brite because they're kind of shoot up looking and we'll smooth em out that's better and we'll get something like that now a incisal embrasures gingival embrasures surface extra anatomy the size is very very important that one I will not hand out that one I will dig a hole behind the hotel and bury high not for the faint of heart I do have another one of those catastrophes that more than happy to give out if you can make it home with it all right if you do and it's in one piece let me know you're welcome all right so that being said if we can go put up the green stage put up the slides again we'll bounce around here a little bit quickly now obviously that wasn't as sexy as that is but kind of working upside down and backwards is a little bit tricky but you guys kind of get the point right we could see the same thing I did here now that you've seen me do it back on this one although this one definitely does look nicer that's kind of what we're looking to achieve and nothing I did and I tell everybody that's nothing I did or ever do is something that you're not capable of doing that's really important I don't believe that I do anything special nor do I believe that I'm special at all when we talk about this stuff but I really believe you guys can do this so we're ending a little bit early which is not so bad but I am out of gas I would like to thank you all from the bottom my heart for being here for pretty much the largest hands-on demo anybody's ever seen in their life right this was awesome thank you guys so much and up I've always wanted to say this like us on Facebook there's our social media thank you so much everyone you
