[@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.

[@GurpreetSingh-mw7ns]

Great help Dr. Stevenson thank you 🌄

[@StevensonDentalSolutions]

Awesome - thank you!

[@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.

[@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.

You are too good sir.. really enjoyed your tutorial.

[@StevensonDentalSolutions]

So nice of you

[@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?

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.

[@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.

Hi Dr.Stevenson! Can you please tell me what does an “ undercut “mean?

[@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.

[@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?

[@m.a.c.4469]

What happens when too much tooth is filed down and end up too short ? Also is there sensitivity after this procedure??

[@StevensonDentalSolutions]

This can definitely happen. Proximity to the pulp is one of the causes of pulpal pain.

Hi doctor,great video👍🏼may i ask Why is the mesial finish line higher than the distal ?

[@StevensonDentalSolutions]

Followed tissue.

[@dddiii3279]

Hello doctor. I'd just like to ask if polishing and finishing is necessary? Shouldn't it be kept rough to increase retention?

[@StevensonDentalSolutions]

Great question! Rough diamond preps have inherently more retention due to a surface area increase and the potential for micro mechanical locks with the cement, however, they also lead to problems and omissions in the laboratory. The rough prep will be made smooth by the lab with die spacer as the crown will be made undercut free, and this is done with actual dies and virtual dies from scans. Labs require an undercut free prep and these micro locks are undercuts. Smooth preps allow for the easy removal of wax patterns with less potential for distortion. The discussion could go on and on but the bottom line is this - those clinicians who make smoother preps consistently see better fits from labs. Dr. Richard Tucker learned this over 50 years ago and his work lasted a lifetime...Good macro-mechanical retention wins in the end - proper taper, adequate length of the walls and optimal line of draw - a smooth prep eases the fabrication process, even though a slight decrease in retention may be seen, it is not clinically significant. The fit of a crown on a smooth prep is unbeatable. Cements should be only used as luting agents in these cases, not adhesives.

[@James-ky7ev]

Dr.,just wondering... how about using a tapered fissure bur, how does that compare to using a straight fissure? Isn't it easier to establish the axial taper of tooth with the tapered bur?

[@StevensonDentalSolutions]

Yes, but the issue with most of these tapered burs is that they don't allow for easy creation of the radial shoulder finish line, without "stair-stepping". There are a few from Dr. Winter (from Brasseler) that have solved this issue using a double radius curve to the end of the diamond - check them out here: shop.brasselerusa.com/Catalog/Diamonds/Crown-And-Bridge-Diamonds/Peter-Brasseler-Series-Premium-Diamonds/5024416U0

[@jagmohan15]

for premolar teeths is emax crown better or zirconium crown better. which crowns are more durable and which one will need more reduction in teeth for fitting the crown

[@StevensonDentalSolutions]

Lithium Disilicate requires slightly more occlusal reduction but may need less axial reduction if the stump shade is acceptable. Zironcia usually requires slightly less occlusal reduction, however, more axial reduction. With at least 3 types of Zirconia available the strength varies dramatically between the types: 3Y, 4Y, and 5Y (Yttria dopants). Unless the patient is a bruxer, I would typically utilize e.max due to its esthetic features.

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.

Have you tried the Double Cord technique? USe braided cord, never knitted. Soak the Alum impregnated cord size 0 and 1 in hemogin (25% Aluinum Chloride and place both into the sculs. Add a comprecap over the tooth and have the patient bite for 5 minutes. Remove the cap, rinse, pull the top cord, dry, repack the bottom cord alical to the margin and keep dry dry dry, then inject into sulcus and flood the tooth. If this doesn't work, let me know - I have more tricks up my sleeve!
