| Abstract | ||||
| Aim:This RCT further explores maximizing the benefits of using PSIs in Orthognathic surgery. Does it improve the postoperative stability of the operated maxilla and does using different designs change affect that outcome? Subjects and Methods:A Randomized clinical trial was done to compare the stability of the operated maxilla following orthognathic surgery. 34 patients were recruited from the Oral and maxillofacial surgery clinic and were divided into two groups: the first group a one-piece fixation plate was used, while a two-piece fixation plate was used in the second group. Immediate and four moths postoperative CT scans were done to evaluate the stability using seven dental and bony landmarks Results: There were no statistically significant differences (P ≤ 0.05) between the two groups in all seven landmarks used for stability measurements, indicating the absence of significant clinical stability between the two groups. Conclusion:Based on this research findings, the two different fixation schemes proved to be very similar after 4 months of surgery. Further longer-term studies are indicated to reach final conclusions about the use of PSIs and the best use of VSP in orthognathic surgery. | ||||
