Study Overview
Brief Summary
patients will be divided into two groups (n=10) according to the type of abutment used: Group (1): will receive conventional shoulder abutment. Group (2): will receive customized titanium biologically oriented prepared abutments or shoulderless abutments that are prepared in the same manner as the natural abutment teeth in the BOPT protocol
Construction of the crowns:
Patients in both groups will receive porcelain fused to metal crowns.
