[The effects of twin-block magnetic appliance on the early skeletal Class III malocclusion].
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.


CONCLUSIONS
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.
