Non-surgical Treatment of an Adult Patient with Class III Malocclusion Using RPE Appliance and Anchor Value Control

In adult patients with skeletal Class III malocclusion, orthodontic treatment with orthognathic surgery may be the best choice for stability and esthetics. However, non-surgical camouflage treatment can be performed considering the patient s non-acceptance, risk and high cost of the surgery. For successful treatment, functional and aesthetic factors must be considered together with skeletal correction. This clinical case report presents the nonsurgical orthodontic treatment of a patient with skeletal Class III malocclusion, narrow maxilla and anterior crowding. The proposed treatment involved maxillary expansion using RPE (rapid palatal expansion) appliance and anchor value control. After 18 months of the total treatment, her occlusion was significantly improved by orthodontic treatment, and the harmonious smile was also obtained. Seven months follow up records after treatment showed excellent results with a good stable occlusion.
