[HIRANUMA-6] Significance of conducting research on the temporomandibular joints
[Abstract]
It is essential to consider the temporomandibular joint in prosthodontic treatment because it affects the occlusal relationship. In some patients, problems on the temporomandibular joints cause significant pain and/or acquired malocclusions such as open bite. However, the etiology and pathology of the changes in the occlusal relationship following degenerative bone changes in the mandibular condyle are still unclear, and treatment protocols for patients with acquired open bite have not been fully established.
Based on the above background, our longitudinal study using the intraoral scanner revealed that mandibular position can change owing to structural alterations in the TMJ caused by mandibular condyle resorption, but changes in condylar shape observed using imaging may not always reflect as changes in the occlusal relationship (Takaoka. et al, J Prosthodont Res 2024). In addition, we demonstrated that rs8044769 in the FTO gene could be involved in the development of temporomandibular joint osteoarthritis (Takaoka. et al, Clin Oral Investig 2022). In this presentation, I would like to introduce the data obtained from approximately 2500 patients with symptoms of temporomandibular disorders who underwent MRI and explain the significance of conducting temporomandibular joint research.
