Abstract
METHODS: 90 patients with irreducible ADD of TMJ treated from August 2020 to August 2021 were acquired in our hospital. They were randomly divided into control group and trial group randomly. There were 45 patients in each group. The sufferers in the control group were treated with oral drug therapy and small incision reduction and suture, while those in the trial group were treated with small incision reduction and suture linked with functional appliance. The pain score, dysfunction, joint function recovery, facial improvement, and clinical impacts of the two groups were contrasted. RESULTS: Compared with that in the control group at 1 week, 4 weeks, and 6 months after therapy, the pain score in the trial group was markedly higher. After therapy, in the two groups, maximum vertical opening (MVO), left lateral excursion (LLE), and right lateral excursion (RLE) levels were markedly higher than those in the control group. The MRI score of the trial group was markedly higher than that of the control group at 1 week, 4 weeks, and 6 months after therapy, and the total effective rate of the trial group was markedly higher than that of the control group. CONCLUSION: The use of small incision reduction and suture linked with functional appliance in the therapy of sufferers with irreducible ADD of TMJ is beneficial to relieve pain, promote the recovery of body function, and contribute to the recovery of joint function.
