| Abstract Objectives: The purpose of present research was to clinically and radiographically evaluate the accuracy and effectiveness of customized titanium plates in Le Fort I orthognathic surgery. Materials and Methods: Ten participants with dentofacial abnormalities were included. Preoperative CT scans were used for virtual surgical planning (VSP), the design and fabrication of cutting guides and customized titanium plates. Clinical evaluations focused on the accuracy of the cutting guides and plates, dental occlusion, operative duration, soft tissue dehiscence or infection, plate fractures, and screw loosening. Postoperative CT scans were used to assess the accuracy of the customized plates using Mimics Medical 19.0 and 3-matic Medical 11.0 software through superimposition and measurement of discrepancies in millimeters. Written informed permission was acquired from all participants. Every participant underwent both clinical and radiographic evaluations. Results: There were no statistically significant differences between VSP and postoperative outcomes at the five pre-selected reference points, with discrepancies of 0.80 ± 0.26 mm (MSP), 1.10 ± 0.23 mm (FHP), and 1.08 ± 0.25 mm (CP) (p > 0.05). All patients achieved stable postoperative occlusion. One patient experienced transient upper lip numbness, which resolved within two months. No cases of plate loosening, infection, or soft tissue complications were reported. Conclusion: Customized titanium plates demonstrated high accuracy in translating the VSP into the operating room. The observed variations amongst planned and postoperative results were minimal and clinically insignificant. Additionally, the use of customized plates significantly reduced operative time and facilitated surgical procedures. Keywords: VSP, PSI, customized titanium plates, POSG system. | ||||
