Aim: To investigate the long-term outcomes of dentoskeletal changes induced by facemask therapy using miniplate anchorage in growing Class III patients. Materials and Methods: Twenty Class III patients who received facemask therapy with miniplate (miniplate group, mean age: 10.6 ± 1.1) and 23 Class III patients who were treated by facemask with rapid maxillary expander (RME group, mean age: 10.0 ± 1.5) were selected for this retrospective study. The two groups’ dentoskeletal changes were evaluated using lateral cephalograms of pre-treatment (T1), about 9 months after facemask treatment (T2) and at post pubertal period (T3). The cephalometric changes in the two groups were compared by the statistical method (Mann-Whitney U test). Clinical success rates for both groups were calculated at T3. Results: In the comparison of short-term effects (T2-T1), greater advancement of the maxilla was observed in the miniplate group. In observations of T2-T3 period, the miniplate group showed less relapse tendency. After long-term observation period (T3-T1), more favorable intermaxillary relationship was observed in the miniplate group. Clinical success rates were 95% in the miniplate group and 85% in the RME group at T3. Conclusions: The miniplate group showed greater advancement of maxilla and less relapse tendency of the Class III characteristics than the RME group. So the miniplate group had more favorable dentoskeletal relationship and better clinical success rate after the circumpubertal growth.
