The skeletal class III malocclusion population takes around 5-8% population in Taiwan. The current orthodontic treatment on the class III malocclusion includes extraction the teeth, applying the temporary anchorage device (TAD) and functional muscle training. Revising the outcome of class III malocclusion treatment, if the class III malocclusion is dental origin without skeletal discrepancy, post treatment results are acceptable. But in some cases treatment, patient may achieve acceptable occlusion but still poor esthetic. In such a case, the treatment plan should combine orthodontic with orthganthic surgery treatment. The orthognathic surgery technique includes apical osteotomy, Maxilla Lefort I, bilateral sagittal split or vertical ramus osteotomy and genioplasty. After the orthodontist and oral surgeon team works, the esthetic outcome may show there is still a room for improving esthetics to be a better result. This lecture is going to discuss what are the orthodontists should know on the cosmetic problem and provide the better esthetic information to the patient.
Define the skeletal class III or mandible prognathism or maxilla retrognathism, identify the diagnosis of skeletal problem.
Determine the orthodontic and orthognathic surgery method started from the end of the outcome.
Illustrate orthognathic surgery case which combined with plastic surgery outcome.
