ABSTRACT
<p><b>OBJECTIVE</b>To study three-dimensional finite element analysis for external midface distraction after different osteotomy in patients with cleft lip and palate (CLP).</p><p><b>METHODS</b>Three-dimensional FEM models of Le Fort I, II and III osteotomy in CLP patients were established. External midface distraction were simulated. An anteriorly and inferiorly directed 900 g force was applied to bilateral maxillary arch in directions 30 degrees to the occlusal plane. Biomechanical changes for the maxillary complex were investigated by means of finite element analysis.</p><p><b>RESULTS</b>Maxillary complex was advanced after different osteotomy. Constriction of alveolar crest and palate occurred in Le Fort I osteotomy, but not in Le Fort II and III osteotomy. Clockwise rotation occurred in Le Fort I osteotomy complex. Counterclockwise rotation occurred in Le Fort II and III osteotomy complex.</p><p><b>CONCLUSIONS</b>Three-dimensional finite element research on external midface distraction could provide reference for the preoperative design.</p>
