  Background: Various complications of dental implants have been reported as cases with long-term implant use increase with its spread of use. It has been reported that residual cement is involved in approximately 80% of the peri-implantitis cases, and prompt management of residual cement is important. This study examined cementation of the superstructure and how the level of gingival margin of abutments affected the amount of residual cement. The study also examined the level of abutment margin to avoid residual cement.Materials and Methods: Working models were prepared using epoxy resin. Implants were placed in one part of the maxillas. Silicone rubber was used to simulate peri-implant gingiva. Morphological designing was performed for the abutments and superstructures on the prepared models. The examination was performed on four levels of abutm.. View More»
