@salmanasim8980 2 года назад

Thank you Doctor for this tutorial. In reality, when caries is shallow but includes proximal area, do we prepare box for composite restoration or only extend enough to remove carious area? Why do we need proximal box and gingival clearance when composite provides micro mechanical retention and preserve tooth structure? Thank you in advance

@StevensonDentalSolutions 2 года назад

You need to break contact in order to: 1. visualize caries removal at the enamel margins, 2. facilitate matrix placement, 3. confirm adaptation and seal of the composite, 4. allow for finishing of the composite and inspection for voids. Small lesions (E1 and E2) without cavitation don't require surgical intervention. The philosophy is this: if it's small and uncavitated, it requires a pharmacological approach, not surgical, however if it is cavitated, and you must drill, then do it thoroughly.

@mam.a1229 4 года назад

Another awesome video! Thank you so much. What is the main difference between class 2 in composite and amalgam? Any videos on the tunnel prepration?

@StevensonDentalSolutions 4 года назад

Composite has more rounded internal line angles, may have flared exit angles and is typically smaller in width and depth, however, not always, as the prep outline is determined by caries.

@KHgoalkeeper21 4 года назад

Hello Dr. Stevenson, all of these bur uses are amazing, but I've started to noticed that small diamond high speed burs are quite common among restorative dentistry community to remove caries. I was wondering if maybe you could do a Class I/II restoration of premolars or molars of your choice? I've used them in clinic and I find that more review with this bur usage will help others. It's quite unique in that because it's a round bur, you can actually angle the bur so that it's not "perpendicular" to the occlusal plane when using say a 330 carbide bur. This would potentially increase vision when approaching occlusal surfaces of the upper arch and help with suctioning in real patients!!!

@KHgoalkeeper21 4 года назад

I hope this wasn't too confusing

@StevensonDentalSolutions 4 года назад

Okay good. Keep it up.

@stormraven989 8 месяцев назад

For a composite prep, should the walls be divergent or convergent?

@StevensonDentalSolutions 8 месяцев назад

It really may not matter much, but traditional convergent walls will add to the retention of the composite and might be of importance when minimal enamel remains.

@hodasaleh6072 5 лет назад

why you made a conventional old design for class 2 composite ? I mean this design is indicated for amalgam ... thanks in advance to your amazing videos .. I learned alot from it

@StevensonDentalSolutions 5 лет назад

The WREB exam demands this - it's not a true class II amalgam either - the extensions are less, line angles are not sharp, the depth is less and there are no retention grooves. Thank you!

@oakamz8718 5 лет назад

Thanks for the high quality videos doc. Is there any alternative to the 330RGS for smoothing the pulpal wall in composite preps? What did you use before it was developed?

@jemimachatla7911 5 лет назад

Thank you so much for the wonderful prep. Doc, can you please make a video of #20 DO for amalgam. While I am trying to make the facial exit angle, it's flaring up and I am ending up with obtuse exit angle. If I am trying to avoid that, I could barely get any facial clearance and having an acute exit angle.Appreciate if you can help.

@StevensonDentalSolutions 5 лет назад

Try prepping the box first with ideal extensions and exit angles, THEN, add the occlusal area - you'll see a huge difference.

@stevensondentalsolutions What should be the hand piece speed on a electric hand piece for beginners 200K or 100K?

@StevensonDentalSolutions Год назад

Either - the issue with too slow is the need to use more pressure - the issue with too fast is the speed at which tooth structure us removed. The speed may be modulated with the foot pedal to a certain extent.

@1smail.khaled 5 лет назад

The same as amalgam prep but with more conservation and rounded line angles but with occlusal divergance Not occlusal convergence . Is that correct ? Or there is also occlusal convergence ?

@rinjujohn795 5 лет назад

Dr. Stevenson, can you let me know what was the cavity depth of proximal box both facially and lingually? Because the mandibular premolar has a lingually inclined occlusal table, should the gingival seat follow the same or if it should be flat what is the minimum depth at proximal box(lingually) in this case? Thank you

@StevensonDentalSolutions 5 лет назад

The box dimensions are not absolute. They are determined by the contact size and the need to remove caries and break contact. The gingival seat (better nomenclature = gingival wall) has no relation to the pulpal wall or the plane of the occlusal table, but is determined by the need to break the gingival contact in a uniform fashion. The pulpal wall is always (ALWAYS) parallel to the occlusal table for all teeth.

@rebeccabahar3754 Год назад

For the adex exam, how far mesiodistally do you extend the box before asking for a mod? The manual says 1.5mm past the DEJ bht that would be 2.5mm (really big) before asking for a mod. Are we better off asking for a mod at 1.5mm (0.5mm into dentin) or will we be docked for asking for a mod before meeting the maximums

@StevensonDentalSolutions Год назад

Great question. THe best approach is the following: 1. Prep to ideal in all respects. 2. Extend only those areas that need to be extended to remove caries (first outline, then internal with slow speed and round burs). Make these extensions close to the max but not quite...and 3. Ask for further mods in 0.5 mm increments. If you do 1 and 2 properly, you'll have little to ask for in step 3. Sometimes nothing. Yes, it is entirely possible to ace this prep with no interaction at all with the floor examiner. The team at CDCA understands that these teeth are tricky. They want you to leave stain and only remove that which has explorer "tug back".

Sir ..when I do box preparation where caries is very little ... I go for composite but get fractured in few months ..why is it?

@Ahuromazda Год назад

Is the S curve just on the buccal side or both sides?and what's the aim of it?

@StevensonDentalSolutions Год назад

The "S" curve is simply a smoothing of the outline from the occlusal to the box - it increases the resistance form of the restoration. It occurs anywhere that a sharp edge needs refinement.

#Q: sometimes facing difficulty in recognize between infected dentin &affected.. Dr Do you have any advice help?

@StevensonDentalSolutions 5 лет назад

First of all, the enamel and DEJ must be pristine, then soft to the explorer peripheral dentin caries is best to be removed. From this point on, it's a much harder call but essentially, remove what won't expose the pulp, and leave hard stained dentin. Thank you Doc!

@YourBetterOffBlack 5 лет назад

Doctor Stevenson, what are your thoughts on using an acorn burnisher for composite restorations? My dental school does not have it in our D1 kits so I’m tempted to buy my own to try it out

@StevensonDentalSolutions 5 лет назад

I think it may work, but using the wall and lobe technique, building the lobes or triangular ridges individually will create nice anatomy and the grooves will form as the natural intersections of the lobes.

@martinlaird4738 4 года назад

Dear Dr Stevenson, I love the idea of having enamel hatchets for clearing contact points and cleaning up the proximal box. But here in Scotland we don’t use them and instead clear them using burs which to me is just asking for iatrogenic damage. I was wondering if you could do one prep video where you do it using a handpiece and particularly that stage of the prep so I can see a way of helping to minimise damage.

@StevensonDentalSolutions 4 года назад

Will do!

@cooldentico1 5 лет назад

With all due respect, are we not supposed to bevel the cavo-surface line angels for composite restorations? I have been taught in my dental school in India to do so and I have been following it all my life. The rationale, to prevent micro leakage caused by the eventual disintegration of bonding agent. Please correct me if I'm wrong.

@StevensonDentalSolutions 5 лет назад

Hi, bevelling composites serve two main purposes: they increase the bond strength/retention of the final restoration due to the enamel rod configuration which results after beveling, and they help blend the composite more seamlessly for esthetic cases (large facial class III and IV, and Vs on the enamel wall only) Using bevels for other classes, like class II's is a double edge sword - the bevel may increase the seal, but flowing the composite into the proximal acute area created by the bevel is unpredictable, and often results in voids. Bonding to enamel will not disintegrate - it is the strongest bond we have so the rationale isn't quite correct. We never bevel any areas that will be in function, as the thin composite will be subject to fracture over time. With most class I, II and III preparations, retention is not an issue and bevels are usually avoided to facilitate better filling of the cavity. Thank you for the question!
