Recruiting now · Not applicable
Conditions studied: Endodontically Treated Molar, Marginal Fit, Internal Fit
In brief
First, Participants in this study will be recruited according to inclusion criteria. Proper examination for the participants (clinically and radiographically). Preparation for endodontically treated molar for receiving high performance polymer endocrown. Checking and verification for the restoration (trying) and assessment of marginal and internal fit by replica technique. Then final cementation of endocrown.
