About this trial
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.
Eligibility criteria
This trial accepts healthy volunteersQualifiers
Patient age range from 18 years -50 years old. They should be able to read and write so they can sign the informed consent.
Patient should have a good physical and psychologically state to be able to withstand the steps of the restoration procedure.
Have a molar with root canal filling with no active periodontal or apical involvement.
Patients having root canal treatment teeth indicated for endocrown treatment with 3 or 4 axial walls remaining.
Disqualifiers
Patient with periodontal or apical involvement or improper root canal treatment.
Severe loss of the tooth structure in which the amount of the remaining tooth structure is less than 2mm.
Patient with poor oral hygiene or with occlusal instability
Patient with improper physical or psychological state.
