Double Anterior Segmental Osteotomy Under Local Anesthesia for Correcting Adult Protrusion With Thin Alveolus and Ankylosed Tooth

摘要

Backgrounds: This paper describes an additional benefit in double anterior segmental osteotomy to correct severe anterior protrusion in adult patients with extremely thin mandibular alveolus and ankylosed tooth. For the optimal anterior segmental retraction, an ankylosed posterior tooth needed surgical inclination reposition. During anterior segmental osteotomy surgery under local anesthesia, additional single tooth osteotomy was performed without challenge.
