短牙弓對(duì)患者顳下頜關(guān)節(jié)的影響
[Abstract]:Objective: To study the temporomandibular joint load and the relationship between the short dental arch and temporomandibular joint disorder in patients with short dental arch.Methods: The original data of head and face were obtained by CT scanning, and a three-dimensional finite element model was established to compare the stress and load of temporomandibular joint between complete dental arch and short dental arch. Result: The stress and load of TMJ increased with the shortening of denture arch. The clinical examination showed that TMJ stress and load increased with the shortening of denture arch. Conclusion: Short dental arch is not a risk factor for temporomandibular disorder, but should be paid attention to the changes of temporomandibular joint in patients with short dental arch.
