[Treatment effects with expansion and multiloop edgewise arch wire technique on skeletal class III malocclusion with mandibular deviation].

OBJECTIVE

The purpose of this study is to evaluate the methods of treatment on Class III malocclusion with mandibular deviations, and clarify the principles of expansion and multiloop edgewise arch wire technique.

METHODS

8 skeletal class III with mandibular deviations patients were selected (male 3, female 5, aged 12-18). They were all corrected with maxillary expansion and multiloop edgewise arch wire technique.

RESULTS

In all cases, molar relationships were class I, the overbite and the overjet were normal, and the upper and lower midline were harmony.

CONCLUSION

Mild and moderate skeletal class III with mandibular deviation can be corrected successfully by maxillary expansion and multiloop edgewise arch wire technique.
