Surgical treatment of dental and skeletal Class III malocclusion.

Orthodontic preparation for surgical treatment of skeletal Class III malocclusion involves joint planning with an oral and maxillofacial surgeon to address the functional and esthetic needs of the patient. In order to allow surgical manipulation of the jaws in the preoperative phase, the need to achieve a negative overjet through incisor decompensation often leads the orthodontist to extract the upper first premolars. This report illustrates an orthodontic preparation case where due to specific factors inherent in the patient's psychological makeup retroclination of the upper incisors and proclination of the mandibular incisors was achieved without removing any teeth. This case was presented to the Brazilian Board of Orthodontics and Facial Orthopedics (BBO) in partial fulfillment of the requirements for obtaining the BBO Diploma.
