Fabrication of a customized impression metal jig for an implant‑supported overdenture with a milled bar

Abstract

The use of computer‑aided design/computer‑aided manufacturing technology simplifies the
laboratory and clinical steps for the fabrication of implant prostheses. It also reduces additional
costs for the prosthetic components and technical procedures. This article describes a modified
impression technique using an impression metal jig to enhance the accuracy of final impression
and also to eliminate the need for the try‑in of resin pattern of the milled bar.
