Multidisciplinary orthodontic-orthognathic management of severe skeletal Class III malocclusion and anterior open bite

Abstract

This case report presents the multidisciplinary management of a patient with severe skeletal Class III malocclusion, anterior open bite, dentigerous cyst, and multiple restorations. The patient underwent orthodonticorthognathic treatment, autotransplantation, cyst removal, and esthetic rehabilitation with porcelain veneers. The presurgical orthodontic decompensation of the proclined upper incisors involved mini-screw-assisted entire upper arch distalization. The bimaxillary osteotomy included advancing the maxilla, mandibular setback, rotating the maxillomandibular complex clockwise, and moving the chin posteriorly. The role of multidisciplinary treatment is very important in orthognathic patients with compromised dentition. Autotransplantation could help patients avoid the need for prosthetic implants. Entire arch distalization could be a possible alternative to premolar extraction for presurgical orthodontic decompensation in cases of proclined incisors.
