I love occlusion. Crazy, huh? I may be one of only a dozen people on the planet who truly enjoys thinking about where the dots and stripes go, but hey, that’s all part of my wonderfulness.
I used to have a collection of distoincisal corners from porcelain restorations in a little plastic lab box in a drawer in my lab. I kept them until I finally knew why they all ended up in that box rather than still being on the patient’s tooth.

I had to learn to evaluate how incisal edges relate to embrasure form and to the teeth they rub against. I used to leave that to my lab, thinking that my ceramist certainly knew more about anatomy than I did and that he would take care of those issues for me.
When I seat anterior restorations today, it is only after I completely understand how the provisionals or composite mock-up are functioning, and no matter how skilled my ceramist, I still expect to refine the incisal tables in the mouth. My ceramist can get close, but he doesn’t have the benefit of the patient when he does the restorations.
If I have paid attention to my workup, my mockup and my provisionals, I will have a great handle on any refinements that need to be done. I can check the incisals in all excursions and crossover and probably only need a rubber wheel.
The incisal edge is really a table; a flat rectangular area about 2mm wide that supports the tooth when it is in contact with opposing anteriors. It should be a mirror image of the incisal table it opposes and should have its leading and trailing edges rounded so that they move smoothly against opposing teeth.


Gravity is precise in nature, governed by laws and formulas; it does not respond to individual circumstances or objectives. It’s easy because it always works. Clinical dentistry, on the other hand, is science to be sure, but an inexact science at best. Inexact science requires the skill of an artist to create a consistent and predictable result since it is not a matter of an equation, hence the “Art and Science of Dentistry.” This inexactness is why each of us come to a fork in our road daily, and it’s not always easy to know which path to follow.
