Objective: The aim of this study was to evaluate the effect of magnetic functional and orthopedic approach on treatment of early skeletal class III malocclusion.
Methods: A new type of magnetic twin-block appliance (TMA) was developed and used on 32 growing subjects with skeletal class III malocclusion.
Results: The class III dentofacial profile significantly improved and class III molar relationship was corrected in most cases.
Conclusion: The Nd2-Fe14-B TMA could be used as effective orthopedic approach in treating class III malocclusion, which had many advantages, such as force prediction, well-controlled anchorage, small and comfortable design of appliance and good cooperation from patients.
