咬合板治疗磨牙症的磨牙信息监测研究

目的　应用自行研制的磨牙症监测仪客观评价稳定型咬合板与尖牙高型咬合板治疗磨牙症的临床效果。方法　将 2 0名磨牙症患者随机分为两组 ,在受试条件基本一致的情况下 ,于低于息止颌位 0 5mm的高度分别制作稳定型咬合板与尖牙高型咬合板。应用自行研制的磨牙症监测仪监测每名患者治疗前后的磨牙时间与磨牙次数。结果　尖牙高型咬合板组患者磨牙时间与磨牙次数明显减少 ,治疗前后差异有极显著性 ;稳定型咬合板组患者治疗前后的监测数据差异无显著性。结论　磨牙症监测仪能自动测量和记录戴咬合板的磨牙症患者的磨牙数据 ,有一定的临床应用价值 ;尖牙高型咬合板治疗磨牙症的临床效果明显优于稳定型咬合板。

A study of electric information monitoring in the treatment of bruxism with occlusal splint

Objective An electric monitor of bruxism had been invented in order to evaluate the curative effect of cuspid occlusal upheaving splint and stabilization splint. Methods 20 patients with bruxism were randomly divided into two groups. A cuspid occlusal upheaving splint or a stabilization splint was fabricated respectively for patients. The vertical dimension for each splint was 0.5 mm lower than mandibular postural position. Sleeping time,bruxist time and times of bruxism were recorded with bruxism monitor that was invented for studying bruxing. Results The bruxist time and the times of bruxism were decreased obviously in patients with cuspid occlusal upheaving splint,while no significant difference was shown before and after using the stabilization splint. Conclusions The bruxism monitor can automaticly measure and record the data of bruxism with splint,which is valuable for clinic. The curative effect of cuspid occlusal upheaving splint is better than that of stabilization splint for treating bruxism.
