摘要

Cement-retained implant-supported restorations are commonly used, and have advantages and disadvantages. Retention of implant-supported crowns by using cement eliminates unesthetic screw access openings. Another advantage is the potential to compensate for minor dimensional discrepancies in the fit of multiunit restorations by using cement and the cement space.1 However, cemented implant-supported crowns are more difficult to retrieve for subsequent maintenance.1 If the location of the access screw opening is not known, the removal of a cement-retained implant-supported restoration with a loose abutment screw or fractured porcelain may result in difficulties and perhaps irreversible damage to the restoration or the abutment#
