Seven studies focused on OMDs associated with malocclusion sagittal characteristics (Class I, II, or III), ten examined open-bite-related OMDs, and seven explored OMDs following orthognathic surgery. Only four studies (22%) were randomized controlled trials (RCTs); most studies lacked proper randomization procedures, did not report allocation concealment, and three of the four RCTs were open-label. Among the six comparisons identified, five were deemed plausible (four with a level of evidence 3 and one with a level of evidence 2). No comparisons were rated at level 1 evidence. As a result, the effectiveness of OMT alone or in combination with orthodontic treatment for the conditions of interest could not be conclusively confirmed. Further well-designed RCTs are needed to confirm or refute this finding and to strengthen the overall evidence base.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Although no high-level evidence currently supports the effectiveness of OMT for managing OMDs associated with malocclusion traits, its potential effectiveness remains plausible.
