Study Summary

This investigation will be a clinical trial to study the performance of a newly developed high strength ceramic material for crowns. The ceramic has been approved by the FDA for patient treatment. A computer technique will be used to fabricate the crowns in a single appointment without the need for a temporary crown or second appointment. Two adhesive resin cement techniques will be used to hold the crown to the tooth and they will be evaluated for creating sensitivity to the tooth. The purpose of the study is to measure how well the high strength crowns function over an extended period of time.

Primary Outcome

Restoration failure is scored by visual loss of the crown from the tooth requiring replacement of the study crown with a new crown at any time between delivery and five years.
