Dear Dr. Stevenson, Why is that the outlines for DO on #13 and #4 are different? This one looks more flared to me that the DO for #13 on Columbia. I tried DO #4 and really struggled with getting the right exit angles and the right amount of clearance.. I was trying to mentally follow the same outline (relatively straighter lingual extension like that for #13). I went back to this video to check where I went wrong and figured it looks different! Also, any tips for using hatchet on both the walls of the boxes sitting at 12'o clock? I'm struggling to get a good support for my hatchet and get the right push downwards. Thank you so much. Best, Adi

Beautiful prep !! Just a suggestion Dr. Richard , it would be great if you could remove the prepared tooth from the typhodont and show us the tooth from all angles so we could get a good idea of the extension lines. Thank you and God bless you for the wonderful work you doing and for all your contribution to our field of dentistry!!

Dear Dr. Stevenson, i certainly wish to express my sincere gratitude to your efforts in preparing such great visuals for us, however, wont it be nice if you prepare things in its original sequence? What i mean to say is, if you have to perform restorations on a Nissin teeth/ typhodont why you remove them out of socket and MARK IT, PUT IT BACK into the Socket? Why don’t you please show in its original steps, because, when a dentist is going to restore teeth, well, they wont take the teeth out of the socket to mark it down? Thanks for your support

Dear Dr. Stevenson, Unrelated to this video but regarding the restoration of class 2 amalgam MOD in maxillary molars. Even though I'm burnishing the band against the tooth well and maintaining a proper seal, I keep encountering an overhang on the mesial. Also, if there is no IPC available, how should I proceed with just the 1/2 Holleback to carve out the interproximal? I tried your technique to use matrix band and kind of slicing the amalgam in the Interproximal but it still looks bulky from the top and in the center. Thank you. Best, Adi

@StevensonDentalSolutions

Жыл бұрын

Use an explorer too. Place two wedges rather than one - approach from both buccal and lingual. Remove the band immediately after condensation - don't carve with the band in place - this leads to firm amalgam interproximally and difficulties in its removal.

Thank you doctor for this amazing video Excuse me I have one question How much the depth of the box should be? I am feeling that with Columbia typodont we need to go more gingivally to get an adequate clearance, is this true? Thanks in advance

@StevensonDentalSolutions

4 жыл бұрын

Yes, that is what this video is all about. The extension of the box gingivally is determined by the contact and the need to establish 0.5 mm clearance.

Dear Dr. Stevenson, Thank you for this video! I wanted to share that whenever I make the distal proximal box in #13 or #4, I tend to make it trapezoidal in shape. I have noticed through your preps that it should be rectangular shape. What could I be doing wrong? I also tend to make the axial depth of about 2 mm in the distal box in Columbia typodont. Could you please suggest some tips to keep the axial depth proper and not make the box wide. ( With 330, 245 &56 carbide burs only) Please throw some light on the MOD preparation for #13/ #4. 🙏 And its extension and which chair position would benefit to accomplish the task. Thank you so much. 🙏 Best regards, Adi

I have a new video coming soon which will address these questions - hang in there! For now, keep the 245 really close to the adjacent tooth and SEEK THE GINGIVAL CLEARANCE first, before the buccal and lingual - this seems to help. ALSO, you may wish to try a BOX ONLY prep and try to get the shape more rectangular, but be careful not to be too rectangular and undermine the enamel...Keep at it! Best wishes, Dr. S

Excellent work as usual 👏 But I have a question, please In the dove tail, you have preferred to go towards the facial surface saying it is not necessary to go lingually , but why have you chosen to go towards the facial rather than the lingual surface?!🤔

Typical design is to go facial, as these secondary grooves are usually the most prominent.

Sharp enamel hatchets were designed for cutting enamel. We used to prepare an entire class V with nothing but hand instruments in my early days...BUT - try using sharp thin burs, even diamonds, like a needle bur with an adjacent tooth protector. Hope this helps.
