Abstract :

Abutment screw fracture is a challenging technical complication in implant retained restorations. When an abutment screw is fractured or deformed, it must be removed without damaging the implant body for the new abutment. Once the internal threads are damaged the clinician can either remove the implant and place a new one which will be an expensive and invasive option, or abandon the implant and cover it with soft tissue, which may lead to compromised function, phonation, or aesthetics. Therefore, salvage of an implant with a non–retrievable screw fragment or damaged internal threads may prove beneficial to the patients. This article describes a relatively cost effective and less time–consuming method for salvaging an implant with damaged internal threads using custom cast post and core.
