Subject. Syndrome of pain dysfunction of the temporomandibular joint is one of the common pathologies of TMJ. Patients with this diagnosis complain of a violation of the movements of the lower jaw, discomfort and pain in the joint. The writings of many authors contain a deep and comprehensive discussion of various aspects of this problem, and scientific justification is given that TMJ dysfunction is almost always accompanied by muscle symptoms. One method of treatment is the use of occlusal splints. In this regard, the task of determining the effectiveness of eliminating muscular-articular dysfunction using individual occlusal splints is relevant. The aim of the study was to determine the effectiveness of treatment of TMJ dysfunction with occlusal splints according to kinesiography. Methodology. The kinesiographic study on the Myotronics K7 apparatus consisted of sequentially performing functional tests (opening and closing the mouth, lower jaw movements to the side) and using the method of percutaneous electroneurostimulation. In the treatment of all patients, an occlusal positioner splint was used, which was made individually in an articulator using an interocclusal register in the neuromuscular position of the lower jaw. The average treatment period was 4.5 months with monthly adjustments to the occlusal splint. Results. As a result of treatment with the use of the occlusal splint, disturbances in the trajectory in the transverse (in 70 % of cases) and sagittal (in 65 % of cases) planes were eliminated, the position of the lower jaw in the neuromuscular position (in 100 % of cases) was normalized. Conclusions. Treatment of patients with TMJ dysfunction using individual occlusal splints is one of the most effective ways to treat this pathology.

Tmj Pain

A clinically similar entity to classical migraine is seen in certain dental patients suffering from temporomandibular joint (TMJ) pain dysfunction syndrome. Patients selected for study gave symptoms of classical migraine on waking. Facial pain on waking is typical of some cases of TMJ dysfunction syndrome and the hypothesis was tested that some patients with symptoms of classical migraine were at the extreme end of the spectrum of dysfunction syndrome. However, rather than experience muscle or temporomandibular joint pain these patients had symptoms on waking which were typical of classical migraine. Nineteen patients with migraine symptoms were provided with acrylic occlusal splints for nocturnal wear. A good clinical response with considerable reduction in frequency and severity of pain attacks was achieved.

As a result of examination and questionnaire of 143 patients who applied for orthopedic treatment of defects of teeth and dental rows, it was found that signs of dysfunction of temporomandibular joint with preserved dental rows are diagnosed in 36—55% cases, and with defects of dental rows — in 45—90% cases. The absence of eighth teeth in the dental row does not significantly change the functional state of the dental-jaw system. A statistically significant frequency of signs of EHS dysfunction has been identified among individuals having terminal dentition defects.In patients with terminal dentition defects, each 3rd patient is diagnosed with cochleovestibular syndrome, and in each 2nd, sounds are determined in the area of VNHS when the lower jaw moves. It has been found that if 15—13 and 12—11 pairs of antagonist teeth are preserved, the signs of dysfunction are determined in 55—45% cases, if the number of teeth having antagonists is reduced to 10—5 (in 90.0% these are patients with preserved 7—8 pairs of antagonist teeth), then the frequency of dysfunction signs increases to 75.0% (t1-3=1.33; t2-3=2.00), in such patients significantly more often — in 75.0% of cases, mandibular deviation is diagnosed when opening and closing the mouth than in persons with a large number of preserved antagonist teeth, respectively 55.0% (t=2.66) and 45.0% (t=3.93) in 1 and 2 groups. Thus, the identification of such signs as crunching, clicking in the joints, hearing loss or tinnitus, suggests the presence of intra-articular disorders in such patients. The deviation of the jaw from its main trajectory when opening the mouth indicates the possible involvement of the masticators muscles in the pathological process. All this requires the dentist to carry out early diagnosis and timely orthopedic treatment.

Occlusal splints (Michigan splints, night/bite guards or bite-raising appliances) can be an effective, inexpensive and reversible treatment for a wide range of dental problems. Objective The aim of this study was to analyse retrospectively the provision of occlusal splint (‘Michigan’ type) in general dental practice, following a prescription by a restorative dental consultant. Method One hundred patients were recruited from consultant clinics in a department of conservative dentistry during 1995 and 1996. All patients were prescribed a maxillary, full-coverage, heat-cured, acrylic-resin splint (Michigan splint) as part of a treatment plan. An explanatory letter and questionnaire were sent to all patients and to their referring general dental practitioner in 1997 and 1998. Results A response rate of 79% was achieved in obtaining completed questionnaires from both patients and general dental practitioners. Of respondents 43% (34/79) received an occlusal splint of some form. A small proportion of the respondents (16.5% [13/79]) received a Michigan splint as prescribed. Irrespective of the type of appliance provided, most patients (82% [28/34]) found them helpful. Of those who did not receive an occlusal splint, 38% (17/45) of patients felt financial implications deterred them from obtaining an appliance. Other common reasons for non-provision included: patients felt that symptoms had improved (18% [8/45]) and patients did not agree with treatment (18% [8/45]). The general dental practitioners had similar opinions to their patients. Discussion These findings raise some serious doubts on the efficacy of consultant clinic advice in the prescription of occlusal splints in general dental practice. The financial and educational issues raised by this study will need to be addressed to improve service provision. Conclusion The results of this study indicate that 16.5% of patient respondents prescribed a Michigan splint at a consultant clinic received such an appliance in general dental practice.

AbstractSuccessful treatment of foot and ankle diseases requires an accurate diagnosis. In addition to differentiated history taking, clinical examination is the most important component in the diagnosis of foot and ankle diseases. The present video explains the common provocation tests and functional tests that are used in the basic clinical examination of the foot and ankle complex. In addition to general inspection and palpation, the focus is on different diagnostic tests and clinical signs that improve diagnostic accuracy. The present basic clinical examination methods allow a structured approach to clinical issues and can be a good basis, if supplemented by further specific and individual tests.

Purpose One popular method to study the motion of oral articulators is 3D electromagnetic articulography. For many studies, it is important to use an algorithm to decouple the motion of the tongue and the lower lip from the motion of the mandible. In this article, the authors describe and compare 4 methods for decoupling jaw motion by using 3D tongue and lower lip data. Method A 3D position estimation method (3DPE), an adapted version of the estimated rotation method (ERM) proposed by Westbury, Lindstrom, and McClean (2002) for 3D recordings, a linear subtraction method, and a new method called Jaw and Oral Analysis (JOANA) were evaluated with data recorded from sensors attached to the lower molars, lower lip, and tongue. Results The 3DPE method showed the fewest errors. However, unlike the other methods, it requires more than one sensor attached to the lower jaw. Among the single-sensor methods, JOANA was found to be the most comparable to 3DPE. Conclusion The findings suggest that JOANA is efficient in decoupling tongue and lower lip motion from jaw motion, whereas ERM, with its less complicated procedure for attaching the lower jaw incisor sensor, can be considered a viable alternative.

Mechanical Aeration

The gaseous exchanges of terrestrial insects are regulated by (i) the opening and closing of the spiracles—the “diffusion control” of Hazelhoff (1926, 1927)—and, in the larger and more active forms by (ii) the mechanical aeration of the tracheal system by pumping movements—“ventilation control.” Spiracular and pumping movements may occur at the same time; for example, in those insects in which a directed stream of air is driven through the main tracheal branches (Fraenkel, 1932; McGovran, 1931); and then the spiracles, by allowing air to pass through them in one direction only, are believed to play a part in the mechanism of ventilation. The object of the present work was to study in greater detail than hitherto the spiracular movements of an insect in which these are not complicated by mechanical ventilation. For this purpose the common rat flea of the tropics, Xenopsylla cheopis , has proved an ideal subject.

The aim of this study was to investigate the manifestations of headaches in adult patients with types of malocclusion and occlusion deformities. Methods and Results: The study was conducted in 171 adult patients (43 men and 128 women) with malocclusion and occlusion deformities at the age of 18 to 62 years old, who were examined in the orthopedic dentistry clinic. The nature of the dentition closing was studied directly in the patient's oral cavity, and with the help of the "Gnatomat" universal articulator on diagnostic plaster models of the jaws. The occlusal relationships of the teeth were analyzed in the position of the central, anterior, lateral and dynamic occlusions. The biomechanics of the lower jaw movements were studied in 3 mutually perpendicular directions. The detected anomalies and deformities of the occlusion were grouped as sagittal, transversal and vertical. Each group was diagnosed as independent forms of malocclusion, and combined with other anomalies and deformities of the dentoalveolar system. All the subjects were asked to answer the questions of a questionnaire specially developed for our study. The unified questionnaire was developed based on a modified rating questionnaire and the determination of the life disorders index in neck pain. The questionnaire includes blocks of questions aimed at identifying the localization of the headache in the temporal, parietal (in one or both) regions, occipital, frontal regions and in the longitudinal seam region. We identified complaints of patients with pain in adjacent regions of the head. Of the 171 examined adult patients with malocclusion and occlusion deformities, 99 (57.9%) complained of headaches. The presence of a headache in the parietal region of the head was associated most often with sagittal and transversal malocclusions. The presence of a headache in the temporal part of the head was associated often with vertical malocclusion The results of correlation analysis showed that pain in 2 regions of the head was associated with malocclusion: the temporal region (rb=0.9892, P=0.0013) and parietal region (rb=0.9712, P=0.0058). Other regions were not statistically significantly associated with malocclusion. Conclusion: There is a certain relationship between the types of malocclusion, occlusion deformities and localization of headaches in adults. Headaches in the parietal and temporal regions of the head are associated with malocclusion and occlusion deformities more often. The obtained data can serve as a basis for the development of recommendations for appropriate corrective measures in orthodontic practice.

Occlusal Interferences

Occlusal splints are used to protect teeth, relieve orofacial pain, and preview the patient response to a simulated occlusal correction. This chapter outlines proper occlusal splint fabrication that employs T-Scan analysis to verify a therapeutic occlusion. The T-Scan provides objective relative occlusal force and timing data that guides the refinement of a splint's occlusal scheme. Therefore, this chapter explains adjusting an occlusal splint's contact pattern with ink ribbon followed by the T-Scan. It also addresses the controversy regarding the existence of, or lack thereof, a relationship between occlusal interferences and masticatory muscle dysfunction. The author postulates that the research studies that argue against the existence of a relationship are absent of occlusal measurement and lack a scientific basis to deny a relationship exists. Lastly, recommendations are made to include the T-Scan in Temporomandibular Disorder treatment studies with both occlusal splints and natural teeth, so that researchers might resolve this controversy for dental clinicians.
