Reduction Ring

The Reduction Ring
Englewood, Colo.

As many of you probably know, I am a big fan of depth cut-based preparation techniques. In my opinion, they are a foolproof way of ensuring you get adequate reduction and thus a functional and esthetic restoration. Some dentists are too set in their ways to consider trying a new prep technique, but the fact remains that the majority of the posterior crown preps we receive at the lab are under-reduced. Enter the Reduction Ring. Unless your patients have translucent cheeks, checking occlusal reduction on a molar visually is substandard. With a 1.5 mm or 2 mm Reduction Ring, you are able to watch the ring slide between teeth to indicate if you have enough reduction on the lingual cusp of that upper first molar. The best news? No more calls from our technical advisors asking you to re-prep and re-impress!
