Class III malocclusion with severe anteroposterior discrepancy

Abstract

This study aims at reporting the clinical case of a patient with Class III skeletal malocclusion with severe maxillary deficiency, producing a reduced midface associated with severe mandibular prognathism. The pre-surgical orthodontic preparation was composed mainly by dentoalveolar expansion and repositioning of the incisors in the lower arch. Then, a combined maxillary and mandibular orthognathic surgery was performed. The treatment objectives were achieved, with significant improvement in facial esthetics and occlusion, followed by post-treatment stability. This case was presented to the Brazilian Board of Orthodontics and Facial Orthopedics (BBO), as part of the requirements for obtaining the title of Diplomate by BBO.

“…Patients with dentofacial deformities are at disadvantage in society due to low self-esteem, decreased confidence levels, as well as associated physiological problems. This facial and dental deformity impairs the mastication, speech and swallowing, and affects the social behavior of the individual in its multiple aspects, 26 thus affecting the entire spectrum that constitutes the quality of life. 22,[27][28][29][30] Esthetics motivates patients with dentofacial deformity to seek for orthodontic treatment and orthognathic surgery as a treatment option.…”

“…20,21,37 besides allowing earlier postsurgical orthodontic treatment, without the fear of disturbing the new jaw positions. 26,54 Finally, orthodontists should be aware of the orthognathic principles and limits in orthodontic movement and must be experienced and skilled with the skeletal anchorage technique, which is essential to achieve predictable three-dimensional molar movement. The interaction between Orthodontics and Surgery can achieve results that would not be possible if either treatment was applied independently.…”
