Abstract: Cement-retained method is the main retention method of fixed implant-supported denture and is widely used in clinics. Compared with screw-retained implant-supported restorations, cement-retained method offers superior aesthetics and lower production costs in the lab. Cement-retained method is easy to obtain passive fit. However, residual excess cement is a serious potential trouble in clinical practice, which is the main pathogenic factor of peri-implantitis and may even lead to implant failure. How to reduce residual excess cement is a problem that implantologists must pay attention to. In this review, five aspects of reducing residual excess cement are summarized from the management of dental crown and abutment, application of barrier materials, cements, and abutment dies, in order to provide clinical guidance for preventing and reducing cement-related complications.
