Thank You for this very well-presented informative video! Finally I found a decent instructional video for class 2 on maxillary premolar. I'm a dental student and your videos are of big help...definitely worth subscribing.

Amazing! I just finished the WREB licensing exam this past weekend, and this would have been a phenomenal addition of knowledge for my Class II preparation. A couple professors at my school say they know you; one a friend and another your classmate in dental school! The latter said you were holding a CE course sometime soon at UOP, but I wasn't able to find information on it. I would love to know if you'll be holding a course in the SF area anytime soon. Thank you for your wonderful videos!

@Adi-jj5ih Год назад

Dear Dr. Stevenson, Could you please explain the concept of exit angles with an example of maxillary 2nd premolar? It's a little hard for me to imagine. I tried extrapolating the concept you discussed in #30 class2 but most of the times it's a hit and miss on maxillary premolars for me. Especially with MOD cavity. It would be very helpful if you could draw the outline or perhaps sometime you could make a video on MOD #13 or #4. 🙏 Thank you so much for being our light of knowledge. Best regards, Adi

Great video! does the dove tail need to be extended in the same buccal position of the box? And is it recommended to start with 7 o'clock in the direct vision to do this class 2 prep?

@StevensonDentalSolutions 5 лет назад

Not sure what you mean by the dove tail extending in the same buccal position of the box - the dave tail usually extending buccally about 0.5 mm or more towards the buccal wider than the isthmus. I's do the entire prep from 11 or 12 o'clock.

@innatep4411 5 лет назад

Stevenson Dental Solutions Thanks! I see what u mean, the dovetail needs to extend 0.5 mm buccally, and it is not related to the box.

@StevensonDentalSolutions 5 лет назад

Cool - glad this makes sense. Thank you for your question!

@salihayounis1508 Год назад

Please repeat the measurement of burs and how it relate to cavity to depth and width

@StevensonDentalSolutions Год назад

330 = 1.6 mm = ideal pulpal depth minimum 245 = 3 mm = good start to dropping proximal box, but gingival wall location is determined by need to break gingival contact. both the 330 and 245 are 0.8 mm wide. The axial depth, measured at the gingival is 1.2-1.4 mm which is about 1.5 x the bur width.

@danielkangX 3 года назад

DR. Stevenson I am having a problem with #13 DO dove tail mounted on the pole, I don't have any problem with #4 on the pole neither #13 on a table, it's very challenging with the mirror. Either dove tail gets larger or accidentally passed too far marginal ridge area leaning mesially and facially for divergence. Thank you for the videos..

@StevensonDentalSolutions 3 года назад

This is the time when you must use direct vision. Lean the head towards you, fully reclined, and watch the bur move directly.

@mam.a1229 4 года назад

Thank you so much,amazing demonstration. My school doesn't allow hand instruments for class 2 , any advice please?

@StevensonDentalSolutions 4 года назад

Use thin burs like the 169L or even a small flame like the 7901 to achieve clearance. The rest will be with the burs as best as you can. Too bad they don't allow hand instruments! Strange.

Dr; what should the angles be of the lingual and buccal walls on the distal surface?

The same - 90 degrees relative to the unprepared surface or minimally flared.

What is the thickness of the proximal box from axial wall to outwards doc

@StevensonDentalSolutions 3 года назад

1.2-1.4 mm on plastic teeth and 0.5 mm into dentin on real teeth (at least 1.0 mm) This measurement is termed the "Axial Depth."

@mam.a1229 3 года назад

Do you the occlusal lock distal to the buccal fissure? Thanks

@StevensonDentalSolutions 3 года назад

Yes about 0.5 mm towards the buccal

@younusaltaie1077 3 года назад

May I know if you are inclining the bur when you are doing the buccal wall?

@StevensonDentalSolutions 3 года назад

Yes, just enough to compensate for the convergent nature of the bur in order to create an orthogonal gingival buccal angle.

@Adi-jj5ih Год назад

Dear Dr. Stevenson, Could you please share some tips to finish the class 2? Most schools don't provide slow speed for exams in that case what is the best way to get a nice and smooth surface in class 2? Many times my line angles in the box don't look defined and the occlusal cavosurface margins look sharp as well. I have tried running 330 in low speed (high speed handpiece with low foot pedal pressure) but it still doesn't look smooth.. the fear of widening the isthmus is of course present. Hatchet leaves scratches too. Someone suggested I try using dull burs like 245 to polish the prep. Haven't tried it yet. I know one school that might give us a slow speed handpiece but I haven't ever practiced in that setting. Would you suggest I give it a shot directly in the exam? Eagerly waiting for your MOD preparation guidance on #13/ #4. 🙏 Thank you so much for clearing so many of my doubts. 🙏 Best regards , Adi

@StevensonDentalSolutions Год назад

I've never found that dull burs are a good idea for smoothing - but rather sharp burs with a feather or brush stroke - aimed at the sharp areas, not the entire wall.

@afrozekhan2269 3 года назад

Hi Dr, for class 2 proximal box, buccal wall needs to be convergent relative to gingival and lingual wall at right angle to the gingival in the upper premolars and molars as well just like the lowers?

@StevensonDentalSolutions 3 года назад

Not exactly. For maxillary teeth the lingual wall is convergent relative to the gingival wall. The facial wall forms a right angle with the gingival wall. For mandibular teeth the lingual wall forms a right angle with the gingival wall, while the buccal wall is convergent relative to the gingival forming an acute angle. Easiest way to remember this principle is that the wall adjacent to the functional cusp is always convergent.

@@StevensonDentalSolutions perfect 👍..thanks alot!

@sadaftaheri5555 Год назад

@@StevensonDentalSolutions hello Dr. Thank you for the great videos. so, are you saying one wall should be parallel to the gingival wall and one wall should be convergent?(as it has an acute angle?)

@sadaftaheri5555 Год назад

because in this case, only one wall would be convergent and the other not, am i right?

@innatep4411 5 лет назад

why divergent the dovetail?

Resistance form so the marginal ridge is not weakened

what is the function of 330 bur and 245 bur?

@StevensonDentalSolutions 4 года назад

330 Occlusal - pulpal depth, convergence and outline. 245 Proximal box.

@afrozekhan2269 4 года назад

Hi..how wide should the proximal box be buccolingually and mesiodistally?

@StevensonDentalSolutions 4 года назад

Thank you for the question! The buccolingual dimension is determined by the contact area and the need to break contact, by 0.3-0.5 (ideally). The mesiodistal dimension is determined by the need to prepare into dentin on the axial wall and to go at least 1 mm. Since this is a plastic tooth, the measurement for the gingival width (the proper term is axial depth) should be 1-1.5 mm at the gingival, but I recommend 1.2-1.4 mm to be within the ideal range. You didn't ask about the occlusogingival dimension but I'll add this information too: the gingival wall is located 0.5-1.0 mm apical to the contact area. So you can see there is no standard measurement for the box - it is entirely dictated by its environment.

Hi all, I'm 4 month away from the practical part of my exam to get my approbation (Germany). I need your help to figure out a little problem I have (teeth, phantom head, armamentarium are not a problem). In the exam we are required to work with water cooling, yet all the dental motors don't have that option, anyone got an Idea how I can get a water cooling setup at home? (without ruining my self too much). Thx.

@StevensonDentalSolutions 5 лет назад

There are many systems online (eBay) that sell water systems, however, water collection becomes the challenge...You may be able to use an extra large rubber glove around the typodont to collect the water.
