The etiologies of skeletal Class III malocclusion include excessive growth of the mandible, insufficient growth of the maxilla, or the combination of both. The ideal treatment for severe mandibular prognathism is a combination of orthodontic treatment with orthognathic surgery to setback the mandible. However, nonsurgical approach using mini-implant anchorage could distalize the mandibular dentition and improve the occlusion if the skeletal discrepancy is mild to moderate. In this report, we present the treatment of a 20-year-old male patient with Class III malocclusion and anterior crossbite. Mini-plates were implanted on anterior border of mandibular ramus and used as temporary anchorage devices for distalization of whole mandibular dentition. At the end of treatment, correction of Class III malocclusion and anterior crossbite had been achieved. An examination 3 years 4 months after treatment revealed long-term stability of the treatment results.
