'Surgery First' Orthognathics to Correct a Skeletal Class II Malocclusion with an Impinging Bite

摘要

Surgical-orthodontic treatment of jaw deformities presents challenges in both diagnosis and mechanotherapy. This is particularly true for a skeletal Class II patient with a short anterior face and an impinging bite pattern. Traditional treatment involves presurgical orthodontic preparation, including tooth alignment, incisor decompensation, and arch coordination. In short-face, deepbite patients, however, the heavy occlusal forces often associated with strong muscles can complicate all these processes. Many clinicians therefore elect to postpone most of the orthodontic correction until after surgery.
