Abstract
Introduction: The key factors that determine the success of orthognathic surgery are the optimal diagnosis, treatment planning, and accurate surgical delivery of the preoperative simulation to the operating room. Recently, the development of virtual surgical planning (VSP) and computer-aided design/ manufacturing (CAD/CAM) technology has enabled preoperative virtual simulation to improve surgical outcomes. Aim of the study: to assess the accuracy of the (3D) customized titanium plate for maxillary repositioning in patients undergoing Le Fort I osteotomy in orthognathic surgery compared to the preoperative virtual surgical planning. Material and Methods: This study was conducted on eight patients requiring Le Fort I osteotomy procedure using 3D customized titanium plates. The post-operative computed tomography (CT) scan images was compared to the pre-operative VSP by superimposition. Volumetric analysis was calculated to detect margin of error. Results: The mean superimposition deviation between the postoperative actual bone position and preoperative planned was 0.382 ±0.490 mm Conclusion: using 3D customized titanium plates through CAD/CAM technologies and VSP bring out many advantages including reduced surgical intervention time, increased accuracy of maxillary repositioning and predictable outcomes.
