Class III malocclussion correction through surgical-orthodontic treatment

Abstract

Patient treated in the clinic of Orthodontics of the Universidad Autonoma de Guadalajara, referring as reason for consultation «I can not eat comfortably and I feel ashamed of my facial appearance». A full dentofacial study was conducted. The patient was diagnosed with a skeletal class III malocclusion caused by maxillary hypoplasia and mandibular prognathism. Surgical-orthodontic treatment was determined. The patient and his parents were informed about the treatment, risks, benefi ts, advantages and disadvantages, duration of treatment, costs and post-operatory care. Once the treatment plan was accepted, the objectives were to achieve skeletal class I as well as bilateral canine class I and molar class II. 0.022 Roth appliance placement was indicated with upper 1st premolars extractions, going through the stages of alignment, leveling and space closure. We worked as a team with the Department of Surgery. A successful treatment of pre-surgical orthodontics and maxillofacial surgery (maxillary advancement and mandibular retroposition) was achieved thus obtaining as a result skeletal class I, canine class I and bilateral molar class II. The patient recovered his chewing function and self-esteem by being aesthetically accepted by society.
