영문 초록

This case report describes an orthopedic and orthodontic treatment of a young female patient who had skeletal Class II malocclusion with mandibular deficiency and vertical growth tendency. Favorable anterior growth of the mandible was acquired by using Twin-block appliance. In application of the Twin-block, it was modified using microscrew to reduce the side effects, like lower incisor proclination and upper incisor reclination, which reduces the potential of achieving maximum skeletal effects. The aim of this case report is to present an idea when using the Twin-block appliance. By this method, the proclination of the lower incisors and the reclination of the maxillary anterior teeth could be prevented. Moreover, the vertical growth of the maxillary dentition could be inhibited by using intraoral elastics between the microscrews and buttons on the Twin-block. This idea may be useful in the treatment of the growing skeletal Class II patients with deficient mandible.
