[@amiraliagh]

Thanks for the demonstration, I just took the seminar by Dr.Strupp, simplifying complex cosmetic dentistry, and he said that shoulder preps are the worst margin design and should be avoided at all cost. He advocates thin chamfer margin for all-ceramic restorations. This is directly from the manual we received "The only time a shoulder margin preparation is acceptable is when it pre-exists and cannot be surgically shaped by a periodontist. A shoulder margin should be considered a severe compromise in preparation design, ultimate health and esthetics. The only exception is when the prepared tooth [substrate] color is severely compromised". I was taught in school to do shoulder for all ceramic and zirconia, I was wondering what are your thoughts? He lists these reasons " 1. Refractive index between tooth and restorative material 2. Difficulty of preparation 3. Weakens the tooth a. Mutilates healthy tooth structure b. Precipitates tooth fracture 4. Increases endodontic necessity 5. Fit - Porcelain shrinkage 6. Increases lab time Thanks!

[@StevensonDentalSolutions]

Yes, Strupp has always been a non-believer of the evidence.

[@drnavneetsehgal9696]

Hi Dr Stevenson Thank you for teaching us through your videos. Could you please tell what will be modifications for - all ceramic crown with an internal coping?

[@evilannie]

Beautiful prep. I know you focused on showing the prep and the technique. But what are your thoughts on burying the facial margin subgingivally? Or at least dropping the margin to the gum line?

[@StevensonDentalSolutions]

As dictated by esthetics and biomechanical requirements, equigingival and intrasulcular preps are likely in actual clinical cases.

Very nice and didactic video Dr. Stevenson; I am wondering how long do you take, in reality, from getting patient numb to the cementation of the temporary crown? Thank you for your time and response.

[@StevensonDentalSolutions]

About an hour. I add another 15-20 minutes for each additional tooth - 6 teeth would be scheduled 2.5 hours. 14 teeth (the max I’ll do on a patient in one sitting would be scheduled for 6 hours.

[@tahersand6825]

sir. shouldnt we use half of the diameter of the bur while FL drawing? y u used the full diameter of it?

[@StevensonDentalSolutions]

If the bur is 1.0 mm, you may use 1/2 for emax and about 2/3 for zirconia at the finish line. Zirconia actually requires a thicker margin.

[@yanhuang4826]

Good morning , The preparation is perfect but I usually prefer vertical preparation which saves more healthy dentin . Do you also use vertical technic ?

[@StevensonDentalSolutions]

It's a very questionable technique and NOT supported by much science - only a few poorly done papers and a lot of hype and opinion. I own a dental lab and when we receive one of these preps, we need to spend more time making them work. Taiseer Sulaiman, arguable the world's number one resource for zirconia considers these preps to be significantly problematic from a durability perspective. I'd prefer to follow the evidence with RCTs and Systematic reviews.

[@omaromar11234]

Dr , could you please do a video about vertical preparation (verti prep ) / David Clark’s prep

[@StevensonDentalSolutions]

Hi Doctor - I could (as it it quite easy to do) but I don't advocate this design do to the material demands of the design exceed the strength characteristics of ceramics, no matter how strong. Most technicians find these preps to be very difficult to restore, as well, usually over-contouring them leading to tissue issues. It's not innovative, after all, as dentists have been making feather edge preps for decades. I could be wrong, but I believe this design will be short lived.

[@StevensonDentalSolutions]

If you look from the occlusal and a portion of a wall is hidden by the wall above it, then this is an undercut.

[@ruhiamir_0721]

[@dr.hamidalrubaie6583]

Thanks for sharing Should we use Shoulder finish line in anterior teeth or we can use chamfer finish line ?

[@StevensonDentalSolutions]

For ceramics, use a fillet finish line. It is not a chamfer. It is a shoulder like finish line with a larger internal radius.

[@dr.hamidalrubaie6583]

@StevensonDentalSolutions can we do the fillet finsh line with the same bur that we use with chamfer finsh line?

[@momo9594]

Nice video. I suggest you check the description text.

[@StevensonDentalSolutions]

Thank you!

[@momo9594]

Stevenson Dental Solutions not at all, thank you for the great videos.

[@son.tse369]

How much clearance if the case is of deep bite ????

[@StevensonDentalSolutions]

1.0 mm for zirconia 3Y-TZP on the lingual would be the minimum. Optimally, 1.5 mm, which would work for glass ceramics as well. The prep will need to have a well made fossa and the resulting faciolingual dimension will be thin.

[@jancymathew256]

Pl post one class 4 composite restoration with a precursor teeth

[@yamironnie]

Thanks doctor!!! I have some question below. 1. What will happen if there’s no rounded internal line angle in the all ceramic preparation? I was taught by my teacher that the all ceramic line angle should be 90 degree(resembles with the buccal side of the PFM), which is prepared with a shoulder bur. Is this an old-school concept? 2. What’s the difference between the preparation design criteria of all ceramic, all zirconia, and zirconia veneered with ceramic? 3. Where do you usually place the finishing line? Anterior, posterior teeth, and the teeth with gingival recession?

[@StevensonDentalSolutions]

1. Very old school perspective and very risky. Ceramic will be stronger, less tooth structure will be removed, and the milling procedure or pressing procedure will be facilitated without having a sharp line angle. The recommended finish line today is either a fillet or a rounded internal shoulder. 2. For layered zirconia you’re going to need to reduce more on the facial to allow for porcelain veneering so you should be at least 1 mm deep axially. For lithium disilicate The reduction could be significantly less as little as .5 mm. For Zircoconia monolithic the depth should be between .6 and .8 mm

[@yamironnie]

@@StevensonDentalSolutions thanks doctor!!!

[@yamironnie]

@@StevensonDentalSolutions so today the shoulder finish line is only recommended on the buccal side of the PFM, right? I also saw some doctor choose fillet finishing line in a PFM prep, is that ok?

[@josephryanmabaquiao4825]

dear dr your prep with margin is above gingiva. not all dr will go for that especially anteriors. i want to know your thoughts about it.

For patients, go equi-gingival or below the defects. This vid is for student typodont work.
