Abstract

Objective:The aim of this study was to compare the post-surgical stability of one-jaw versus two-jaw orthognathic surgery in patients with skeletal Class III malocclusion, focusing on skeletal relapse, occlusal stability, and functional outcomes. Materials and Methods:This retrospective cohort study included 70 patients (35 in the one-jaw surgery group and 35 in the two-jaw surgery group) who underwent orthognathic surgery for skeletal Class III malocclusion. Postoperative assessments were conducted at 6 and 12 months using cephalometric analysis, occlusal stability measurements, and patient-reported outcome measures (PROMs) to evaluate skeletal relapse, occlusal changes, and functional recovery. Results: The two-jaw surgery group demonstrated superior skeletal stability with minimal relapse compared to the onejaw group. Occlusal stability, as measured by overbite and overjet, was also significantly better in the two-jaw group at 12 months. Functional outcomes, including chewing function and speech, were more favorable in the two-jaw group, with significantly higher PROM scores. Patient satisfaction with facial aesthetics was also greater in the two-jaw surgery group. Conclusion:Two-jaw orthognathic surgery offers superior post-surgical stability and functional outcomes compared to one-jaw surgery in patients with skeletal Class III malocclusion. These findings suggest that two-jaw surgery is a more reliable approach for achieving long-term skeletal and occlusal stability. However, both surgical approaches can provide significant improvements in functional recovery and patient satisfaction.
