目的:分析中度磨牙症患者软垫治疗前后颞下颌关节振动的特征,探讨软垫治疗磨牙症的效果。方法:收集20例中度磨牙症患者和20例临床无症状的志愿者分别作为实验组和对照组,采用问卷调查和临床检查相结合的方法对磨牙症患者进行分级,用BioPAK口颌功能诊疗仪记录试验对象颞下颌关节表面振动情况。结果:中度磨牙症患者的关节振动能量和振幅明显高于正常人;正常人关节振动的发生率为75%,中度磨牙症患者关节振动的发生率为100%;中度磨牙症患者经3个月软垫治疗后关节振动的发生率为80%。结论:中度磨牙症患者软垫治疗后关节振动的发生率降低,治疗效果显著。
OBJECTIVE: To analyze the characteristics of temporomandibular joint (VJ) vibration in patients with moderate bruxism before and after treatment. Methods: Twenty patients with moderate bruxism and 20 asymptomatic asymptomatic volunteers were enrolled as experimental group and control group. The patients with bruxism were classified by questionnaire and clinical examination. Instrument recorded object temporomandibular joint surface vibration. Results: The energy and amplitude of joint vibration of moderate bruxism patients were significantly higher than those of normal people. The incidence of joint vibration was 75% in normal persons and 100% in moderate bruxism patients. The incidence of moderate bruxism The incidence of joint vibration after 3 months of soft padding was 80%. Conclusion: The incidence of joint vibration in patients with moderate bruxism after treatment of soft pad is reduced, the treatment effect is remarkable.
