Altered reverse impression method involving extraoral digitalization of a verification jig for the fabrication of implant‐supported prosthesis by using a complete‐digital workflow

Abstract

AbstractThe reverse impression method involves the extraoral digitalization of the interim implant‐supported prostheses and intraoral digitalization of antagonist arch and maxillomandibular relationship. This technique allows the fabrication of implant‐supported prostheses by using a complete‐digital workflow. The scan analogs make the reverse impression method feasible. However, this method may not be recommended if the interim polymethyl methacrylate prosthesis does not have passive fit. The present manuscript describes an altered reverse impression technique that involves the extraoral digitalization of a conventional verification jig, which has attached scan analogs. With this technique modification, the implant positions captured using the verification jig are used to obtain the virtual definitive implant cast and fabricate the definitive implant‐supported prosthesis.
