A MANDIBULAR ADVANCEMENT DEVICE

摘要

A mandibular advancement device is dis-closed. The upper jaw (12) has fitted to it an upper plate (30). The upper plate (30) is firmly received, and generally comprises a body com-ponent (32) and two opposed flange components (34), are located to be lying in an area beside and close to the posterior teeth, and particu-larly the buccal side of the upper posterior teeth. The leading edge (36) of the flanges (34) pro-vide engagement surfaces complementing the engagement surfaces of the trailing edges (26) of the lower flanges (24). The relative lengths of the respective trailing edges (26) and leading edges (36) ensure that mandibular advancement is maintained over a desired range of jaw open-ings. The angle of inclination of the engaging edges (26, 36) provides a jaw opening path gen-erally arcuate with the protrusive border path.
