摘　　要：目的研究微型生物反馈治疗仪治疗夜磨牙症的临床应用疗效，以期为夜磨牙症的治疗提供新的思路和方法。方法用微型生物反馈治疗仪治疗10例夜磨牙症患者（女性7例，男性3例，平均26．1岁），治疗仪包括磨牙信息监测、磨牙信息分析及反馈模块，磨牙信息监测模块即在上颌咬合板内放置电阻式应变片采集患者睡眠时的磨牙信息，并无线发射；磨牙信息分析及反馈模块接收和处理磨牙信息，收到持续的磨牙动作信号后通过手表式振动装置，提醒患者有意识进行神经肌肉放松，停止磨牙。分析治疗前、治疗6周和3个月后磨牙次数和磨牙持续时间的差异。结果治疗后6周10例患者的磨牙次数由治疗前的（9．8±2．2）次显著下降至（3．0±1．2）次（P〈0．05），磨牙持续时间由（20．7±12．2）s显著减少到（10．0±3．4）S（P〈0．05）；治疗3个月后，磨牙次数为（2．9±1．2）次，磨牙持续时间为（9．2±2．9）s，与治疗前相比差异有统计学意义（P〈0．05）。结论基于压力感应式的微型生物反馈治疗仪能对夜磨牙症进行监测和治疗，此治疗仪可为夜磨牙症提供有效、安全、简便的治疗手段。Objective To access the effect of wireless biofeedback therapy on bruxism. Methods Ten voluntary bruxers （ seven female and three male, mean age 26. 1 years） were invited to participate in this clinical research. An electric resistance strain gauge was embedded in the position of canine of a maxillary splint for monitoring the abnormal clenching or grinding movement of teeth during sleep. The relevant details of bruxism events, including value of relative force, occurring time and duration were recorded and analyzed by the receiver device and monitoring program respectively. Meanwhile, for the purpose of nerve system and muscle relaxation, a watch-style device around the patient＇s wrist will vibrate to alert the patient of teeth grinding or clenching if the value of biting force and duration exceed the threshold. Total average episodes of bruxism and duration was observed during eight hours sleep, and was analyzed with one-way analysis of variance in SPSS 19. 0 by the end of 6th week and three months following biofeedback therapy. Results The average episodes of bruxism has declined dramatically from （9. 8 ± 2. 2） times to （3. 0 ± 1.2） times during one night （P 〈 0. 05） , and the average duration of bruxism events was reduced from （20. 7 ± 12. 2） s to （ 10. 0 ± 3. 4） s （ P 〈 0. 05 ） after six weeks biofeedback therapy. By the end of three months, the average episodes declined to （ 2. 9 ± 1.2 ） times（P 〈 0.05）, and the average duration decline to （9.2 ±2.9） s （P 〈0.05） with contrast to preliminary night. Conclusions The pressure-based wireless biofeedback device is able to monitoring clenching and grinding of bruxism. The results suggest that biofeedback therapy may be an effective, novel and convenient measure for treatment of bruxism according to several months therapy.
