Abstract:
Objective:To study the occlusion characteristics of the young subjects with bruxism before and after treatment by elastic occlusal splint. Methods:10 patients with bruxism and aged 22-27 years(n=10) were treated by elastic occlusal splint, before and 6 months after treatment they were examined by T-Scan occlusion detector. The occlusion time( OT) , disclusion time( DT) , oc-clusion force( OF) , the perentage of occlusion force( POF) , the changes of the position of center occlusal force( COF) and the asym-metry index of occlusion force(AOF) were observed and compared with those of the healthy controls(n=10). Results: ① In the case group there was significant difference in the OT and DT between left and right anterior teeth before treatment (P<0. 05), but not after treatment (P>0. 05). There was significant difference in the momevent of COF of left and right side, the POF of right side and the AOF between the 2 groups before treatment, but not after the treatment(P>0. 05). ② In the case group after treatment the OT and DT of left and right anterior teeth were shortened(P<0. 05). The POF of right side and the AOF were significantly improved. In the case group DT, OF center excursion, the left POF and the AOF showed no significant difference before and after treatment( P>0. 05). Conclusion:The occlusal factors such as early contact, lateral teeth synthetic interference, occlusal force center excursion have close relationship with bruxism. Elastic occlusal splint can effectively correct muscle dysfunction and make occlusal relationship more coordinated and stable, and therefore is effective in the treatment of bruxism.
