- Class III malocclusion, Reverse Twin Block, growing child
- Class III malocclusion has a great variation of skeletal pattern in either the antero-posterior orvertical planes. If left untreated, Class III malocclusion in the growing children will become worse with age, presented by the growth of the mandible exceeding the growth of the maxilla.A male patient aged 10 years and 6months came to Orthodontic Clinic Faculty of Dentistry University of Sumatera Utara with a chief complaint of unaesthetic appearance of lower front teeth. Diagnosis showed Class III malocclusion with mandibular prognathism, anterior cross-bite, and smaller upper jaw relative to lower jaw. In this case, stage 1 treatment was done by using Twin Block Class III or Reverse Twin Block appliance to correct the skeletal relationship in sagittal plane, obtain normal overjet and also prevent concave and asymmetry facial profile. Reverse Twin Block is designed by reversing the angulation of the inclined planes, drives forward maxillary development and restricts forward mandibular growth by harnessing occlusal forces as the functional mechanism to correct arch relationship. The results of this treatment were the correction of skeletal relationship, normal overjet, and stable facial profile. As a conclusion, Reverse Twin Block appliance can be used as an early treatment for skeletal Class III malocclusion in growing child.
