title: Limiting the dimension of a screw-access hole with an interim screw-retained prosthesis.
abstract: Fabricating an interim screw-retained prosthesis often involves obliteration of the abutment screw access site, which later must be exposed. This frequently results in excessive preparation of the screw access site with poor esthetics and a weaker restoration. The technique described expedites the process by locating the access site and limits the size of the screw access hole preparation.
