You may try an Off-angle Chisel, the 45S for the mesial box and the 44s for the distal - other than that, it can be done with a reverse approach and a palm-thumb grasp - tricky but doable!

Hi Dr. Stevenson, I am wondering if you have an answer for what I am seeing. After placing a composite restoration I noticed on a radiograph that there was a radiolucent area around the filling. I don't know if after light curing the bonding adhesive then packing the composite into place. If the radiolucent area I am seeing is the space where the bonding adhesive lays, or I am not packing the composite correctly. I value your insight and thought you may have the answer. Thanks again. Dr.R

@StevensonDentalSolutions 3 жыл бұрын

Hi Larry, yes, this is most likely the bonding layer, especially if the bonding resin is not highly filled. OptiBond FL is a filled adhesive and doesn't leave this radiolucent pattern, but many of the Universal adhesives do, as they are much less filled. It's good to blow the adhesive thin and use HVAC to facilitate thinning before curing - this may help as well. If the adhesive layer is too thick, the bond strength will be diminished due to the shift from adhesive to the cohesive failure mode. In other words, the adhesive tears apart intrinsically before the dentin-adhesive interface fails.

@lannyrubin2600 3 жыл бұрын

thanks for the quick reply. So i just watched the video you did on Class III composite #9 ML fill where you mention not to light cure the adhesive just pack the composite and then light cure. Do you normally suggest not curing the adhesive like this for all your restorations. and will a radiograph not show the radiolucent area under the composite if you do not light cure it?? Thanks for all your wonderful videos. Lanny

Thank you doc Would like to see a demo of only proximal box class 2, minimal prep , not with occlusal extension, I am struggling with this as in my simulation lab ,everytime my bur ends up going bit further down towards Distal occlusally if preparing a Mesial box only for composite class. 2, have practical exam in a week and my cavity prep still not confining to minimal prep in proximal box only , Also any tips how to view class 2 cavity box prep in manikin indirect vision upper molar please

@StevensonDentalSolutions Жыл бұрын

Keep the bur nearly touching the adjacent tooth when prepping. Shoot for gingival clearance first, then extend facial and lingual. Deep the axial carefully to allow better access. Use a good stable finger rest and take your time...best wishes

i find that it's basically impossible to view the enamel wall since this is the upper 6. any tips on how to safely box prep without hitting adjacent tooth and thinning the wall just enough to break it with a gingival marginal trimmer?

@StevensonDentalSolutions 5 жыл бұрын

I know what you mean - using 3.5x or higher loupes, adjusting your mirror position, and using the "global orientation - finger rest - local execution" technique make it easier. I teach this in my courses - and have great results with the students. View the position of the handpiece and bur with direct vision, then set your finger rest securely, and now look through the mirror with your loupes to initiate the bur movement. Stop and assess often until it becomes possible.

Sir, what is the depth of the proximal box?

@StevensonDentalSolutions 3 жыл бұрын

Gingival Extension or Axial Depth? Axial depth is 0.5 mm into the dentin and at least 1.0 mm total. For typodont teeth we usually find that 1.2-1.5 is good. As far as gingival extension, you extend past the cønact and caries. In most situations, this will create an axial wall height of 1.5-2.0 mm.

Hold handpiece perpendicular to occlusal table - be aware of the curve of Wilson, and use a finger rest to lock your position in. Let the 330 do the work and while refining be mindful of the walls and the angles. Focus on the internal line angles at the end and the bur will take care of it.

@@alicerobinson9533 When you refine, you might be altering the convergence - in other words, making the walls divergent - this is common. When you refine the prep, use the 330 0r 245 and focus on the internal line angles, taking care not to extend the cavosurface margin.
