A system and method for forming a framework of foundation elements as a component of and foundation for an impression and to support a prosthesis to form a final restoration in a patient. The foundation elements and the prosthesis may be made of the same or similar prosthetic material, or of a metallic or metal alloy material. Each foundation element includes a base member defining a bore therethrough and at least one elongate member extending from the base member. To form the framework, each foundation element is attached to an implant in a patient and a free end of the elongate member is oriented and cut such that it optimally contacts a base member of an adjacent foundation element and is rigidly bonded thereto. A rigid framework is thereby produced which is used to produce the impression. The impression is removed from the patient and a master model is made therefrom. The rigid framework is removed from the impression material and placed along with the master model in an articulator. A prosthesis is molded or sculpted onto the rigid framework and the prosthesis is then attached to the implants in the patient. Gaps in the prosthesis are then sealed.
