Abstract:
A method for forming a final biocompatible implant supported restoration comprising a framework and a prosthesis, wherein'said framework comprises foundation elements used for taking an impression of implants in a patient and the same framework is used as a component of the final restoration, said method comprising the steps of:attaching a foundation element via guide pins to at least two implants fixed in the bone of a patient, each foundation element having a base member having first and second ends defining an aperture for insertion of a guide pin therethrough for attaching said base member to an implant; and at least one elongate member extending from the base member, having a first end at a point of attachment to the base member and a second free end that can be cut to optimally contact the base member of an adjacent foundation element;connecting said free end of each of said elongate members of each foundation element to said base member of an adjacent foundation element thereby forming a framework;taking an impression of said framework on the implants in the patient;removing said impression and framework from said implants in the patient;forming a rigid master mold from said impression and framework and containing said impression and framework;removing said impression material from said framework on said master mold; andattaching a biocompatible prosthesis onto said framework to form the final restoration.
