Class II #14 MO Preparation RTX Caries Tooth for WREB

[@georgewhitehead8185]

Thank you Dr. Stevenson for this great video. I carefully studied it, and several other of your videos, and I am happy to report I just passed the ADEX examination (10/2023) Dr. George Whitehead

[@StevensonDentalSolutions]

Awesome!

Great!! Saludos desde Córdoba Argentina 🙂🇦🇷!!

[@StevensonDentalSolutions]

Hi! Thank you for watching!

[@shockwave208]

Great video as always, thank you! Would love to see how you make crown provisionals (using Jet or Provisa)

[@StevensonDentalSolutions]

Will try!

[@MarioOoDMD]

Thank you sir!

[@StevensonDentalSolutions]

My pleasure!

Dear dr. Thank tou very much for your all videos, that you share them. Your videos are very perfect, How can i say you my thank? I really thank for your sharing these perfect videos. I am so sorrry about my bad English.

[@StevensonDentalSolutions]

So nice of you

[@a.s.america]

Dr. Stevenson, thank you for the video. How come the internal axial wall of the proximal box is concave, not convex? Shouldn't we be concerned about the pulp proximity?

[@StevensonDentalSolutions]

The axial depth is still ideal, it's just that the axioproximal line angles are rounded...the idea being that the prep is caries-driven with composite. The pulp is 3-4 mm inside the box. The axial depth would be the same for any preparation, namely about 0.5 mm into dentin. Thank you!

please doc i waiting always for the vertical prep which you promised me since a bout four months i know you dont like it but i trust you and the way you explain technics so a gain please do the demonstration.... CORDIALY

[@StevensonDentalSolutions]

I have the video completed - it's in the queue! Thank you for reminding me!

[@samarthladumor]

Greetings dr. Steveson I had a question with regards to engaging the hatchet in indirect vision to make flaring exit angle for the composite restorations Your advice on this is appreciated

[@StevensonDentalSolutions]

This is very difficult at first. Try moving the head towards or away from you. Use a very sharp new hatchet - a good hatchet, not the $15 eBay version. Try making most of the wall with the bur and use the hatchet to remove only the smallest amount of tooth.

[@MarioOoDMD]

Dr. Stevenson, when you're making a bridge prep, the principle of the prep you make is pretty much the same as for a single tooth crown prep?

[@StevensonDentalSolutions]

With the addition of line of draw, yes. The preps must be sacrificed slightly to accommodate the line of draw and knowing which prep may be altered and which walls and to what degree is the key.

[@actionpotential8749]

Dr. Stevenson, you didn't prep the distal pit in this video. Is the distal pit supposed to be included in the minimum Class II MO prep for maxillary molars (for exam purposes)?

[@StevensonDentalSolutions]

On the WREB the distal pit will be a required carious lesion to remove... You may either connect it to the MO by crossing the oblique ridge, or keeping it separate.

[@Karol00707]

Hey! I’m wondering why are you extending your preparation so much? Don’t we as a dentists need to stick to minimal invasive preparation? Just to remove caries only, not healthy dentine...

[@StevensonDentalSolutions]

Yes, I am showing both prep designs: amalgam and composite - and the WREB allows for a traditional design or a slot prep for composite as well. The slot prep will require conventional retention form as well, vis-a-vis convergent walls. Bonding alone is not enough when most (more than 50%) of the prep bondable surfaces are dentin.

[@hunkoflam1994]

Thanks for the video Dr! Just wondering, how do you prevent the tooth from burning when you're using the high speed without water?

[@StevensonDentalSolutions]

New burs, light touch, slightly lower speed.

[@allantheodor6470]

Great video doc …..I have a question what’s the position to work for molars especially the box area ( buccal and lingual )

[@StevensonDentalSolutions]

For maxillary teeth, I like 11-12 o'clock with the mirror.

[@allantheodor6470]

@@StevensonDentalSolutions I am struggling with the lower molars 😅 especially #30 so what do you recommend for mandibular molars doc thanks a lot

[@StevensonDentalSolutions]

@@allantheodor6470 Cut most of it from 7 O'clock and then finish the box with direct vision from 9-12. It takes time but keep trying different chair positions, with and without the mirror.

Dr Stevenson could u please let me know if you have any course for wreb exam preparation before March ?

[@StevensonDentalSolutions]

We might add one - stand by

[@bilgegulsumnur9344]

Hi Dr.Stevenson, What is the principle of the box cavity? What do you think about this cavity? I have a practical exam and they ask to us this cavity

[@StevensonDentalSolutions]

Box preps are very nice and conservative when no fissures are present on the occlusal. To make them last longer, make sure that the walls are flared to expose much enamel, and also the gingival is in enamel. Also, adding convergence or even retention grooves to the prep will help with macromechanical retention.

[@tayoadewuyi7729]

Thank for the videos Dr. Stevenson. With the wreb exam class 2 composite preparation, can l just stop on the box prep alone if there's no occlusal caries extension?

[@StevensonDentalSolutions]

NO - they want an occlusal extension as well

[@tayoadewuyi7729]

@@StevensonDentalSolutions Thank you....

[@1108steeveee]

In this case for the WREB exam, if you were to request extension because of the carries would you ask for a 1mm extension of the axial wall depth?

[@StevensonDentalSolutions]

Yes, or perhaps 0.5 mm then again 0.5 mm.

Hi Dr. Stevenson, I had a quick question about protecting the adjacent teeth. When I am practicing with the ModuPRO Typodont and the RTX #9 and #14 Caries Acadental teeth, nothing seems to fit interproximally as a guard on these typodonts. I know you sell a NODAT Damage Prevention Kit on your website, and I was wondering if the guards in this kit actually fit interproximally. If they don't, do you have any suggestions as to what you would use that could fit in between these tight typodont teeth? Thank you so much!!

[@StevensonDentalSolutions]

You can make them fit easily with a little separation with a small spoon between the teeth. They will all work well with this technique. Thank you!

[@bibodent]

From where can we buy those teeth models?
