In an electromyographic study of 17 adults suffering from nocturnal bruxism and of a control group consisting of 18 adults without any functional disturbances of the masticatory muscles, the effect of this kind of neuromuscular stimulation on the temporal and masseter muscle was examined. The myoelectric signals were registered before and after TENS treatment in 3 different positions of the mandible. Each person was treated 3 times with both the Myo-Monitor (Myo-Tronics, Seattle) and the TNS SM2 MF stimulator (schwa-medico, Giessen). The different effects of continuous low frequency and intermittent high frequency muscular stimulation were studied simultaneously. Muscular activity was determined by computer aided integration of the electromyographically measured raw signals. A fourier analysis of the power spectrum yielded information on the frequency behavior of the studied muscles resulting from the TENS treatment. A statistical analysis of the results led to the following significant conclusions: 1. TENS treatment decreased the values of the registered integrated signals on all test persons, however, the treatment increased the median frequency and the mean power frequency (MPF). Since this effect is contrary to muscle fatigue, these electromyographic results can be interpreted as providing objective proof of a relaxation in the treated muscles. 2. The electromyographic changes after TENS treatment were similar when using either the Myo-Monitor or the TNS SM2 MF stimulator. In addition, the 2 different types of stimulation (high or low frequency) showed the same effects. 3. Compared to the persons in the control group, there was no significant increased muscular activity in patients with nocturnal bruxism. Following TENS treatment both groups showed the same alterations in the electromyograms. The results of the study provide further evidence that TENS treatment is an adequate supportive procedure in the treatment of nocturnal bruxism.</p>","PeriodicalId":77135,"journal":{"name":"Fortschritte der Kieferorthopadie","volume":"56 5","pages":"245-53"},"PeriodicalIF":0.0,"publicationDate":"1995-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/BF02299665","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18562991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The \"closed form\" questions were designed to provide insight into the patients' motivations for seeking treatment and into their perceptions of its course and outcome. Nine working hypotheses taken from the literature served as the study's starting point. The evaluation of the data gathered revealed that, contrary to other studies, the motivation for patients to seek treatment was not directly related to sex, i.e., was not sex specific, although this must be qualified. The unequal distribution of the sex of the patients who had sought treatment, and who were covered in the survey, points to differences between them in their decision making processes. When the results were evaluated, the data showed 92.2% patient satisfaction and even high satisfaction with treatment outcome. 86.4% of the patients stated that they would recommend the operation to others and 82.9% said that they would undergo the operation again. This high level of patient satisfaction was to a great degree directly attributable to, above all, the positive aesthetic result, the quality of the consultation and care, and to the absence of persisting postoperative complications. When the patients were divided into subgroups by means of using single criteria, significant varying degrees of satisfaction could be distinguished among segments of the subgroups. It was not possible, however, through the use of cluster analysis to separate out with precision the small group of patients who were not satisfied with the overall results of their treatment.</p>","PeriodicalId":77135,"journal":{"name":"Fortschritte der Kieferorthopadie","volume":"56 5","pages":"265-73"},"PeriodicalIF":0.0,"publicationDate":"1995-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/BF02299667","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18562993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It was especially helpful that during therapy simultaneously with exerting influence on the maxillary base plane, the influencing of the occlusal plane occurred in the same direction. Through the additional application of high-pull headgear, maxillary growth was clearly restrained and the inclination of the maxillary base plane inhibited.

When using such torque-segmented arch wires, the crimped connector rests mesially to the canine bracket and the lateral components exhibit a torque of 0 degree. The use of the torque-segmented arch wires requires the practitioner to adjust the anterior tooth segment, to bend in first order bends in the steel lateral portion as well as to bend in a sweep to avoid an anterior tooth extrusion, and, if desired, to bend in third order bends to influence premolars and molars. In some cases the simultaneous application of palatal arches can become necessary, because each torque transfer results in a transversal enlargement in the molar area. Compared to conventional steel wires with dimensions of 0.016 x 0.022 in which an anterior tooth torque is bent, the torque segmented arch wires exhibit considerably fewer side effects, but there is a larger distally rotating moment for the molars. 1. When applying torque-segmented arch wires, the extrusive force transferred to the anterior teeth is considerably smaller. 2. The protrusive force acting on the anterior teeth is also considerably smaller, which results in a reduced demand being placed on the anchorage of the molars. 3. The torque transfer to the incisors rests in a quite moderate range, even in the case of a 50 degrees torque. For this reason, the practitioner can expect diminished or no resorptions at all compared to the aforementioned steel wires. 4.
