doc could you advise how to figure out if the handpiece or the bur is not working optimally?? the frequency of changing the bur or handpiece and the optimum cutting speed?

@StevensonDentalSolutions 3 года назад

I change diamond burs after 3-5 preps. If cutting dry, even more often. The handpeiece should be lubricated daily. and when you turn the bur with your fingers it should move freely with no resistance. Other than that, keep experimenting to find your zone...

Try to achieve 91-110 degrees with respect to the root or unprepared apical tooth surface on the facial finish line. You don't want this to be less than 90 degrees, as this would leave unsupported tooth structure.

@StevensonDentalSolutions Год назад

usually if you prep to the tissue level and reduce 2.0 mm from the incisal, you'll have enough length - it will vary between typodonts and clinical practice, but 3 mm vertical walls mesial and distal would be sufficient.

Hello doctor. In Australian Dental Council exams we have to prepare 1.2mm shoulder. When I do that I tend to get more cutting from proximal areas. Is their a criteria for proximal cutting? Or as long as the taper is fine and margin in transitioning it's ok?

@StevensonDentalSolutions 2 года назад

As long as the measurement is 1.2 and the taper is correct, the results wil be good. If you can use a more narrow bur at first, like a 850-014 this might help...

@paulchahal7545 5 лет назад

Why did you not use end cutting bur, instead using it at the end? I found that, when I use end cutting bur while doing finishing line on buccal surface, my preparation tends to have equigingival shoulder on line angles.(any suggestions to improve on this plz)

@StevensonDentalSolutions 5 лет назад

The end cutting bur is potentially very dangerous, as it can cause internal undercuts. It should be used to simply refine the shoulder carefully. Keep the finish line 1 mm above the tissue before refining - this way, the end result will be 0.5 mm in most cases.

@CR-uz8qq 5 лет назад

Hello, Dr. The margin width is not constant when preparing. And the margins are shaped to be rugged. What should I check for?

@StevensonDentalSolutions 5 лет назад

Great questions: If you have an electric handpiece, turn it down to 2500 and use a finishing diamond to smooth the finish line. Otherwise, use stall-out speed or even a slow speed fitted with a friction grip attachment to refine. Correcting uneven depth takes practice but try using the bur tip to define it more uniformly - the tip of the 8847-016 is 1.1 mm. Another great bur to try is Brasseler's 8881-012 - Best to you, Dr. S

@CR-uz8qq 5 лет назад

@@StevensonDentalSolutions Thank you so much for your kindness. I use only a high-speed handpiece, not an electric handpiece. Is it possible to prepare teeth with FG low speed handpiece? It looks like you're using a fine bur(red band).

What is the difference between the preparation of PFM and all ceramic and zircone Please

@StevensonDentalSolutions 3 года назад

PFM: Facial Shoulder 1-1-2 mm deep and relatively sharp internal line angles, and minimal reduction on the lingual with a chamfer margin. ACC (e.max): 360 shoulder with rounded internal (aka fillet) which may measure between 0.5 for e.max in the most conservative cases to as much as is needed for esthetics, but typically about 0.6-0.8 mm. MONOLITHIC ZIRCONIA: Same as ACC but must be at least 0.8 mm deep axially, but may be less on the occlusal.

The final prep: 2 mm incisal, 1.5 mm facial at incisal 1/3 and 1-1.2 mm at margin. 1-1.5 mm lingual clearance and 1-1.5 mm lingual reduction in fossa. Lingual axial wall is 0.5-0.7 mm (chamfer). I start with less and finish to the final measurements to avoid over-cutting.

It’s all about line of draw. Since the teeth don’t naturally line up, you’ll need to taper the distal of the canine more than if it was a single prep. Also, make sure that you have even shoulders of adequate depth. Making the preps smooth is good but not as important. Best wishes!

Hey.. Did you use 847 KR supercoarse or fine grit??

@StevensonDentalSolutions 3 года назад

847KR-016 is considered a medium grit and has 100 micron diamond particles, and has no color ring on the bur shank. The 6847KR-016 is a coarse grit and has 125 micron diamond particles and has a green ring around the shank. The 5847KR-016 is an extra-coarse grit and has a black ring around the shank. The finishing diamond in this shape (the *847KR* shape) is the 8847KR-016, with a red ring on the shank with 30 micron particles - a fine grit. I use the 847KR followed by the 8847KR, however it works equally well to use the coarse 6847KR instead of the 847KR.

For posterior teeth, bevel the functional cusps. For anterior teeth, simply reduct enough for incisal translucency, facial ceramics and lingual clearance for function. I'd recommend that you carefully watch the PFM and FGC playlists.
