<p>A system and method for forming a framework of foundation elements (10) as a component of and foundation for an impression and to support a prosthesis (68) to form a final restoration (70) in a patient. The foundation elements (10) and the prosthesis (68) may be made of the same or similar prosthetic material, or of a metallic or metal alloy material. Each foundation element (10) includes a base member (12) defining a bore (20) therethrough and at least one elongate member (14) extending from the base member. To form the framework, each foundation element is attached to an implant (26) in a patient and a free end of the elongate member (14) is oriented and cut such that it optimally contacts a base member (12) 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 (56) and placed along with the master model in an articulator. A prosthesis is molded or sculpted onto the rigid framework and the prothesis is then attached to the implants in the patient. Final locking screws are placed. The filing and sealing of each of the permanent screws completes the restoration.</p> |
