Orthodontic Treatment After Surgery of Condylar Hyperplasia

Objective:To evaluate the orthodontic treatment after the surgery of condylar hyperplasia(CH),and to explore the methods for orthodontic treatment.Methods:20 patients(9 males and 11 females),aged 15-36ys with an average age of 25.5ys with condylar hyperplasia after high condylectomy were selected.Straightwire appliance was used for the orthodontic treatment.Routine radiographs including panaramics and cephalometrics were taken before,during and after the treatment.Results:After orthodontic treatment,anterior and posterior open bite was corrected,and normal overjet and overbite were obtained.Satisfactory occlusion was achieved with classⅠor complete classⅡ molar relationships on both sides.Conclusion:Malocclusion after surgery of condylar hyperplasia could be effectively corrected by straight wire appliance,vertical elastics and reciprocal elastics.
