ABSTRACT
Two patients, sought treatment for chief complaints of protruding frontal tooth and desired treatment to reduce the prominence of lips, were diagnosed as bimaxillary protrusion via clinical and cephalometric analysis. The authors corrected them by combined surgical and orthodontic treatment. As pre-surgical survey, paper and cast surgery were performed and wafer and resin sprint were constructed. We performed anterior maxillary and mandibular osteotomies in first premolar site to retract the maxillary and mandibular dentoalveolar segment in order to; 1) Decrease prominence of upper and lower lips. 2) Create proper lower incisor intrusion. By use of intramaxillary fixation, prompt oral intake was possible. We made good result of esthetic improvement and there was no evidence of relapse and any complication.
