Abstract

Purpose:To assess the effect of extraoral polishing of the crown-abutment interface on the marginal fit of implant-supported screw- and cement-retained prostheses (SCRPs). Materials and Methods: In 31 patients, the marginal gap of an SCRP was measured using a stereomicroscope before and after polishing of the crown-abutment interface, and the paired data were compared. Results: The marginal gap was significantly decreased after surface polishing regardless of the prosthesis material (P <. 001). Conclusion: Extraoral polishing of the crown-abutment interface could improve the marginal fit of SCRPs. Int J Prosthodont 2020;33:629–633. doi: 10.1607/ijp.6971
