Abstract
The authors examined the condylar movement in 28 patients with closed locking of the temporomandibular joint before and after treatment and 33 controls by transcranial radiography. The Treatment adminstered to the patients were noninvasive and conservative therapy such as patient education, home care, reductive manipulation, physical therapy and occlusal splint.
The authors obtained the following results.
1. In patient group, the mean amount of condylar translation was 5.07±2.00㎜ in the affected side and was 7.39±3.22㎜ in the unaffected side before treatment, the mean amount of condylar translation in affected side was 12.77±2.75㎜ and in unaffected side was 15.52±2.53㎜ after treatment. And the condylar translation was significantly improved after treatment(P<0.001).
2. In patient group, the ranges of comfortable mouth opening were 27.04±4.12㎜ and maximum mouth opening were 29.96±3.69㎜ before treatment, the ranges of mouth opening were below 40㎜, And the ranges of comfortable mouth opening were 43.86±1.86㎜ and maximum mouth opening were 43.96±1.90㎜ after treatment. And the mouth opening was significantly improved after treatment(P<0.001).
3. In patient group, the mean amount of treatment time was 4.13 ±1.52 months when patients opened above 40㎜.
4. The mean amount of condylar translation was 17.23±2.75㎜ in control group and was 12.77±2.75㎜ in the affected side of patient group after treatment. There was a significant difference between the groups(P<0.001), And in the unaffected side of patient group, the mean amount was 15.52±2.53㎜ after treatment. There was a significant difference between the control group and the unaffected side of patient group(P<0.05).
5. The ranges of comfortable mouth opening were 43.86±1.86㎜ in patient group after treatment and 42.82±4.47㎜ in control group. There was no significant difference between the groups. But the ranges of maximum mouth opening were 43.96±1.90㎜ in patient group after treatment and 46.48±3.85㎜ in control group. There was a significant difference between the groups (P<0.05).
