全牙列软(牙合)垫治疗夜磨牙的临床疗效观察

磨牙症是人在非生理功能状态下,产生上下牙齿彼此磨动或紧咬的现象,危害最严重的是夜间的紧咬牙和夜磨牙。夜磨牙的发病率为9．78％,其病因复杂,治疗方法多,传统治疗方法主要是采用硬学料[牙合]垫,但存在制作相对复杂,易对牙体、牙周、颞下颌关节造成损伤等缺点。由于加压成型机和透明塑睃片的使用,使治疗方法得以改进。本采用全牙列软[牙合]垫,对严重的夜磨牙症患进行治疗,并与硬[牙合]垫治疗进行了比较,取得了良好的临床效果。

目的比较NTI-tss咬合板和稳定咬合板（OS）对于磨牙症的短期疗效。方法10例磨牙症患者采用随机自身交叉对照试验,戴用NTI-tss和OS治疗各1周,于戴用咬合板前一晚、戴用当晚和戴用1周后进行多导睡眠监测,计算磨牙指数和睡眠微觉醒指数,数据采用SAS 9.1混合效应模型进行分析。结果两种咬合板在戴用前、戴用当晚、戴用1周后的睡眠微觉醒指数均无明显差异（P>0.05）。两种咬合板戴用后,磨牙指数均降低。NTI-tss戴用前、戴用当晚和1周后的磨牙指数分别为（7.50±1.11）、（3.45±1.22）、（3.51±1.03）次·h-1,戴用当晚与戴用前、戴用1周与戴用前的差异均有统计学意义（t=26.52,t=26.12,P<0.01）。OS戴用前、戴用当晚和1周后的磨牙指数分别为（7.44±1.23）、（2.97±0.91）、（6.43±1.02）次·h-1,戴用当晚与戴用前、戴用1周与戴用前的差异也有统计学意义（t=16.79,t=3.79,P<0.01）,但与NTI-tss相比,降低程度较小。结论NTI-tss和OS对于睡眠微觉醒的发生无影响,两者都可以降低磨牙指数,但前者对于夜磨牙症的短期疗效可能更稳定。     

Soft versus hard occlusal splint therapy in the management of temporomandibular disorders (TMDs)

Aim

To compare between soft and hard occlusal splint therapy for the management of myofacial pain dysfunction (MPD) or internal derangement (ID) of the temporomandibular joint (TMJ) with reciprocal clicking.

Patients and methods

This study included 50 patients (age range: 24–47 years) who had been diagnosed with MPD or ID of the TMJ in the form of reciprocal clicking. Patients were divided into two groups. They were treated for 4 months with either a vacuum-formed soft occlusal splint constructed from 2-mm-thick elastic rubber sheets (soft splint group) or a hard flat occlusal splint fabricated from transparent acrylic resin (hard splint group). Monthly follow-up visits were performed during the treatment period. Before treatment and 1, 2, 3 and 4 months after treatment, the dentist measured all parameters of TMJ function (pain visual analog scores, tenderness of masticatory muscles, clicking and tenderness of the TMJ, and range of mouth opening).

Results

All parameters of TMJ function showed significant improvement in both groups during the follow-up period, with a statistically significant difference between the two groups at the 4-month follow-up visit.

Conclusions

Both forms of occlusal splints (soft and hard) improved TMJ symptoms in patients with MPD or ID of the TMJ. However, the soft occlusal splints exhibited superior results after 4 months of use.     

咬合板高度对TMD患者咀嚼肌肌电的影响

目的:研究不同高度的咬合板对颞下颌关节紊乱病(TMD)患者颞肌前束、咬肌肌电的影响。方法:73例TMD患者随机分为3组,戴用不同高度咬合板使咬合距离分别增加3mm、5mm、7mm,比较分析戴板前和戴板后即刻测量的双侧颞肌前束(TA)和咬肌(MM)肌电电位。结果:在静息及紧咬状态下,戴用不同高度咬合板即刻测量的TA及MM肌电电位均明显低于戴板前的测量值(P<0.05);紧咬状态下5mm和7mm咬合板对MM肌电电位的降低程度显著高于3mm组。结论:咬合板是治疗肌功能紊乱的有效方法。高度为5mm和7mm的咬合板降低咀嚼肌肌电的能力较3mm咬合板更强。     

[牙合]垫对牙齿重度磨耗患者口颌功能影响的临床研究

Effects of jaw clenching while wearing an occlusal splint on awareness of tiredness,bite force,and EEG power spectrum

PurposeTreatment with an occlusal splint is used for temporomandibular disorders, bruxism, and occlusal disturbance to relieve orofacial symptoms such as myofascial pain and jaw movement restriction. However, the effects of various types of occlusal splints have not been elucidated. We investigated the effects of jaw clenching with soft and hard occlusal splints on the awareness of tiredness, bite force, and EEG activity.MethodsSix healthy adults were used as subjects, with a visual analogue scale utilized to evaluate the awareness of each patient's tiredness both preceding the session and following the clenching trials. In addition, a Dental Prescale was used to measure bite force and an EEG recording was conducted while performing jaw clenching. The jaw clenching task comprised 1 min of maximal voluntary clenching under 3 kinds of clenching conditions: with natural dentition, and with soft and hard occlusal splints, which were each repeated 5 times.ResultsJaw clenching with natural dentition and a hard occlusal splint did not cause a significant awareness of tiredness following repetitive jaw clenching, and there was not a significant alteration of EEG spectrum values with those conditions. In contrast, jaw clenching with a soft occlusal splint caused a significant increase in awareness of tiredness, as well as significant decreases in bite force and EEG alpha 2 power spectrum values.ConclusionsJaw clenching with a soft resilient occlusal splint causes an awareness of tiredness, which might be accompanied by declines in bite force and EEG spectrum values.

Fabrication of an occlusal splint

Occlusal splints used in the treatment of bruxism or occlusal-incisal attrition are not often completely successful in effecting a complete cure. Even if complete remission of nocturnal bruxing is never attained, the hard, smooth polymethyl methacrylate occlusal splint does an admirable job of fulfilling its other functions. It eliminates further nocturnal occlusal abrasion by keeping the patient's teeth apart and by preventing most of the effects of bruxing. The best way of accomplishing this is with a smooth, nonyielding splint andnot with the athletic mouth-guard type of appliance, the very resilience of which is likely to stimulate bruxing and clenching.
