Posted June 19, 2017I’ve always been “aggressively conservative” when it comes to tooth preparation. While the marginal axial preparation is more than what we need today for emax CAD and zirconia, this was required for Empress CAD.
I presented this particular case at the ADA meeting in 2007 and a couple of doctors in the audience told me to the effect: “you can’t do that!” “The tooth will break!” “You need to cover those cusps!”
Well, I think pragmatically before I do a cookie-cutter approach to anything. I assume that the cusps are doing OK next to un-bonded amalgam, so why would they do any less next to bonded ceramic? Now, the lingual cusps had fracture lines that were troublesome, so they came off.
At ten years, I think I made an appropriate choice. I’ve done many of these similar type of restorations, and I’m convinced that teeth need fewer crowns.

If you’re interested in partial coverage restorations, you should come to one of our “Only Onlays!” courses!
