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 improved esthetics. https://fid.tums.ac.ir/index.php/fid/article/view/387 https://fid.tums.ac.ir/index.php/fid/article/download/387/363
