One of the problems I have always had is over, or under-reducing the occlusal on molars. Either I cut away too much and decrease the retention and resistance forms or I do not cut enough away to make room for the porcelain.

I have tried to use a piece of baselplate wax to gauge the reduction. I have also tried utility wax that I ball up and have the patient bite on. In addition, I have also tried making the temporary crown before I take the final impression and looking at my occlusal room. None of this has worked for me.

I saw an advertisement for PrepCheck made by Common Sense Dental. This is a rubberized strip with articulating paper on one side. Comes in 1mm, 1.5mm and 2mm thicknesses. You have the patient bite on the strip and it shows where you need to reduce more. Sounds great. But, these are expensive. Has anyone tried these? What do you think?

Editor’s Note:
According to Common Sense Dental:

“PrepCheck promotes adequate reduction allowing ideal thickness of the final restoration and ensures superior strength and aesthetics. PrepCheck’s special coating marks the tooth in areas that need to be reduced.”
