Dental prosthesis and method

摘要

A permanent dental prosthesis and a method of installing the prosthesis in the mouth of a patient to replace a missing tooth. The prosthesis comprises a body portion, first and second lugs which project outwardly from opposite side edges of the body portion and which are inwardly slidable with respect to each other, a spring element for biasing the lugs apart and a cap receivable on the body portion for defining an outer tooth-like configuration for the prosthesis. In accordance with the method, the prosthesis is installed between a pair of spaced teeth by first forming elongated notches in the inwardly facing edges of the teeth and then assembling and cementing the prosthesis between the teeth so that the lugs are received and cemented in the notches. The spring element is preferably then removed, and a cap is formed over the body portion to provide an outer configuration for the prosthesis which simulates a natural tooth.
