- Abstract
<bold>Purpose: </bold>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).<bold>Materials and Methods: </bold>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.<bold>Results: </bold>The marginal gap was significantly decreased after surface polishing regardless of the prosthesis material (P < .001).<bold>Conclusion: </bold>Extraoral polishing of the crown-abutment interface could improve the marginal fit of SCRPs.
