Abstract
Background:Temporomandibular joint (TMJ) disorders caused by skeletal deformities can significantly affect jaw
function and quality of life. Surgical interventions, such as Bimaxillary Orthognathic Surgery (BOS) and MandibularOnly Surgical (MOS) correction, are commonly used to address these issues. This study aims to compare the effects of BOS and MOS on TMJ function, pain levels, jaw mobility, and recovery time.
Materials and Methods: A total of 60 patients were included, divided into two groups of 30. The BOS group underwent both upper and lower jaw repositioning, while the MOS group received only mandibular correction. Pain levels, TMJ function (jaw mobility and lateral movements), and recovery time were assessed pre-operatively, post-operatively, and 6 months post-surgery. Data were analyzed using descriptive and inferential statistics.
Results: Both surgical approaches resulted in significant improvements in TMJ function, pain reduction, and jaw
mobility. The BOS group showed superior long-term outcomes in pain relief and jaw mobility, while the MOS group
experienced quicker recovery times.
Conclusion: Both BOS and MOS effectively improve TMJ function, with BOS offering slightly better long-term
outcomes. The study highlights the potential of integrating Artificial Intelligence (AI) and the metaverse for improving surgical planning, patient care, and post-operative follow-up.
