Covering the Screw-Access Holes of Implant Restorations in the Esthetic Zone: A Clinical Report

Screw-retained implant restorations have an advantage of predictable reten- tion as well as retrievability, and obviate the risk of excessive sub-gingival cement commonly associated with cement retained implant restorations. Screw- retained restorations generally have screw access holes, which can compromise esthetics and weaken the porcelain around the holes. The purpose of this study is to describe the use of a separate overcasting crown design to cover the screw access hole of implant screw-retained prosthesis for im- proved esthetics.
