Bioprogressive Mechanism에 의한 CIⅢ부정교합의 치험예

Case reports of Angle`s Class III malocclusions treated by bioprogressive mechanism

This present paper describes 3 clinical cases which were treated with Bioprogressive mechanism. Each patient has shown a deficient maxilla combined with prognathic and steep mandible. The purpose of treatment was planned to obtain the forward growth of maxilla and redirectioning of mandibular growth. The most noteworthy approach in the treatment was the application of Cl Ⅲ intermaxillary elastics with upper protraction utility arch immediately after rapid moxillary expansion. In the analysis of the data obtained from pre-and post treatment lateral cephalogram, the result achieved by this method is very favolable to the corrextion of anteroposterior relationship of maxilla and mandible.
