Abstract:

The contribution of malocclusion to temporomandibular disorders (TMD) has been a subject of ongoing debate. Many observational and interventional clinical studies, animal experiments, mechanical studies, and three dimensional finite element simulations have been conducted to investigate this relationship. However, significant discrepancies among research findings have made it challenging to establish a clear understanding. Based on previous findings, it is believed that while there may be some potential associations, malocclusion is not considered a primary etiological factor for TMD. Although further research is required to confirm the association between malocclusion and TMD, it is still noteworthy that the positional relationship between the dentition and the condyle may potentially affect the biomechanical and functional status of the joints. The purpose of this article is to provide a review of current research and offer our interpretation of this topic, presenting new perspectives and approaches for understanding and treating TMD.
