Abstract

Surgical therapy alone cannot successfully treat some deformity of the single jaw. We present a case with maxillary retrognathism. Sagital discrepancy o f 14 mm distance between lower and upper jaw was present. We have the problem in planing of therapy which require booth surgical and orthodontic treatment. Analysis showed that advancement of maxilla will not resolve the problem and therefore we decided to treat the patient with bimaxillary osteotomies. Lost of the permanent teeth makes the problem in preoperative planing. Presurgical orthodontic treatment require application of full banded edgewire application to align the arches for surgical advancement of the maxilla and repositioning of the mandible. The application was also used for bimaxillary fixation after surgery and during the time of retention. Surgical therapy includes LeFort I downfracture technique and bilateral sagital splitting technique according to Bell. The result showed the validity of bimaxillary osteotomies in cases o f deformity o f the single jaw.
