Hi there Dr. Stevenson. I just wanted to say I've pretty much watch all your KZread videos and found each one to be incredibly informative a well as inspiring. I hope one day to be able to match the precision of your preps. I was just wondering if there was a text book you might recommend describing the dimensions and outline form of common cavity and preparations along with the rational for such features. I studied at Kings college London, England and was never taught this level of detail when planning our cavity preparations. Please keep up the great work!

Do you find that hand instruments can be used clinically in the way they’re used on the typodont teeth? Maybe our hand instruments in dental school weren’t properly sharpened, but I don’t remember being able to undermine and create a bird beak, and shave it off so cleanly with the hatchet, like you do on the typodont teeth. I currently don’t have hand instruments in my operative cassette but these videos are making me want them back again!

Yes, absolutely - I use them all the time clinically. Yes, they must be of high quality and sharp. Most dental school instruments are neither! I use them for composites, inlays, inlays, and even crown preps. I will make a video soon of clinical procedures - like an inlay or composite prep. They actually work better on enamel than plastic.

If you realize you lack enough gingival clearance when you chip away the proximal box enamel shells, what would you do in that case to minimize iatrogenic damage but lower the gingival floor?

@StevensonDentalSolutions

5 жыл бұрын

Hi Ryan, in this case, I use the “Sturdevant Chip” technique. Use a 245 and position the bur against the axial wall. Drop the bur ginigivally about 0.3-0.5 mm (takes some practice bur it’s very repeatable), while just skimming the axial wall as you move the bur buccolingually. You will have created a ditch in the gingival which leaves a small wall (a lip) adjacent to the proximal tooth. Now use either an enamel hatchet or bin-angle chisel in the ditch and rotate the instrument with the cutting edge swinging towards the adjacent tooth. The little wall will easily chip off, thereby gaining more clearance. Smooth the margin as you always would with burs and the hatchet or ginigival margin trimmer and you should have an iron clad predictable method for this requirement of class II preparations. Note: Sturdevant, - I knew him personally - was a humble gentleman and would never have named this after himself. Thank you - I hope this helps. I plan to demo this in an upcoming vid!

Hi, it might be by 1 degree but it’s very close. It’s always better to be flared up to 5 degrees vs. being potentially undermined. Imagine a matrix band around the tooth and visualize the angle which the amalgam will make at the cavosurface. I think that you’d agree that in this prep we’ve satisfied the criteria. Best, Dr. S

hi I would like to ask is this the preparation for all levels of decay if so if a tooth doesn't have a large amount of decay spreading to the outer case at both sides of the tooth then why are the walls of the tooth breached on both sides surely it would make sense to keep the shell of the tooth intact as to make a shell for the filling to sit and mould with giving the tooth more integrity in some videos they even go as far as making a complete + shape breaking the integrity of the tooth both sides

For amalgam: There are at least the following 20 designs available to treat class I /II caries, depending on the clinical situation: M (Box only) MO (leave the oblique ridge), D (Box only) DO (leave the oblique ridge), MOD, MODL, MOL, DOL (leave the oblique ridge), DOL cross the obliques ridge, MOB (leave oblique ride) MOBL, DOBL, MODBL, O+O+O, O+O, OL , OL (leave the oblique ride) OB, L pit, B pit in combination with most of the above.

Hi,I would like to know if it’s just a DO where do we start the outline of the preparation...

@StevensonDentalSolutions

5 жыл бұрын

Hi Doc - two choices: either extend all the way to the mesial pit and cross the oblique ridge, or perform a DO which is entirely restricted to the area distal to the oblique ridge. With the first option, it's more aggressive, however, it is very retentive and relatively easy to perform. With the second option, the difficulty lies in obtaining enough retention without damaging the DF cusp with a dovetail. For the distal only prep, start with the BOX and complete it, THEN add enough retention with the occlusal form. This technique works well with small DO and MO preps on lower first premolars as well. I'll demo this video soon! Thank you for the excellent question. If you email me, I will send you a photo: info@stevensondentalsolutions.com

Oh that is just mean! Any chisels at all? Hoe? Off-angle? Bin-angle? Hopefully you may use some instrument - if not, you'll never be able to create defined axioproximal line angles. Very strange for a school to subject one to this. Anyway, do the best you can with the tip of the bur to obtain the proper extensions on the buccal and lingual of the box. It can be don, but it's like asking an F1 driver to take one of the wheels off the car and win a race. BOO!

Place the band as usual, then cut a small piece of the matrix material (a shim), about 10 mm in length, and insert it in the area where you have no adjacent tooth, extending beyond the buccal and lingual proximal walls, then insert a wedge vertically between the shim and the band and secure with composite or compound. this will seal the gingival area beautifully.
