PDF: 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.

Caucasian female patient, aged 17 years and 7 months, reported dissatisfaction with her facial and dental esthetics after undergoing orthodontic treatment to camouflage her negative overjet. The patient's substantially compromised lower face made her feel a deep dissatisfaction with her face. 

The interview revealed good overall health and a family history of mandibular prognathism, a trait inherited from the paternal side.
