TetricCAD Crown Clinical Study
Completed · Not applicable
Conditions studied: Fractured Tooth, Decayed Tooth, Unsatisfactory Restoration of Tooth
In brief
This investigation will be a clinical trial to study the performance of a new resin-based ceramic material for crowns. The material 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. The purpose of the study is to measure how well the high strength crowns function over an extended period of time.
