Abstract: 
Orthognathic surgery, performed to correct functional and aesthetic jaw and facial irregularities, significantly enhances the quality of life for patients. Despite advancements in surgical techniques and computer-assisted planning, postoperative complications such as unintentional occlusion disorders and jaw misalignments remain common. Studies reveal postoperative jaw misalignments and malocclusions in approximately 10% of cases. Relapses after bimaxillary orthognathic surgery predominantly affect maxillary movements, especially in patients with cleft lip and palate, with up to 20% relapse due to scar contraction. Deviations from the preoperative plan occur even with advanced technologies, within generally accepted tolerances of less than 2 mm for translational and 2 degrees for rotational movements. The primary causes of relapse are linked to postoperative stability rather than planning accuracy, with contributing factors including the feasibility of orthodontic pre- and post-treatment, long-standing dysgnathia leading to tooth loss, and advanced patient age. These factors should be carefully considered to minimize the risk of relapse and improve surgical outcomes.
