BACKGROUND: Among the adult socially active population, one of the most common pathologies of the maxillary system is musculoskeletal dysfunction of the temporomandibular joint (TMJ). One of the modern methods of correction and treatment of TMJ dysfunction is splint therapy, which involves the use of splints and permits to consistently and selectively act on a particular level of disorders: occlusive, muscular, articular. This ultimately forms a new myostatic reflex of holding the jaw, builds physiological biomechanics and neuromuscular activity of the speech apparatus and the stomatognathic system as a whole. AIM: To prove the positive effectiveness of the use of splint therapy from the point of view of physiological concepts in optimizing the neuro- and myofunctional state of the stomatognathic system with an analysis of the effectiveness of the mode of using occlusal splints in patients with TMJ dysfunction. MATERIALS AND METHODS: The treatment was carried out in 34 patients with diagnosed TMJ dysfunction at the age from 17 to 40 years. For the treatment of patients, a relaxing therapeutic and diagnostic articular splint was used. The patients were divided into 2 groups of 17 people each: for the first group of patients, a round-the-clock mode of wearing a splint was set, for the second group, a 16-hour mode was set. The total observation period was 6 months. The criteria for achieving therapeutic goals were considered: absence/reduction of pain in the TMJ and orofacial pain, absence of pain on palpation of the masticatory muscles and in the TMJ, stable position of the lower jaw in the central occlusion, stability and uniformity of movements of the lower jaw at various functional positions, comfort when chewing and at rest, absence/reduction of hypertonicity of the masticatory muscles. RESULTS: The treatment results were evaluated 3 and 6 months after the primary stabilization of the mandible position. At the same time, among the patients of the first group, primary stabilization was achieved on average at the third visit (after 1.5 months from the start of splint therapy), in the second group of patients only at the fourth or fifth visit (after 2–2.5 months). Three months later, all patients of the first group and 8 patients from the second group noted a decrease in pain and orofacial pain, as well as the absence of pain on palpation of muscles and TMJ. Chewing discomfort was observed in 4 patients from the first group and 7 from the second. According to the results after 6 months, all patients were satisfied according to all criteria, all established objective criteria for treatment goals were achieved. CONCLUSIONS: With the correct selection of patients with symptoms indicative of muscle or occlusive dysfunction, splint therapy shows itself as an effective method that allows, with a full understanding of the biomechanics and functional physiology of the occlusal-muscular-articular complex, to effectively correct the neuromuscular state of the stomatognathic system towards it full balance.

Bruxism is a parafunctional activity of the masticatory system, which is characterized by clenching or scraping of teeth. This condition is often accompanied by a change in the shape and size of the teeth, as well as the function of the stomatognathic system. Bruxism can occur during sleep and in the waking state. The etiology is multifactorial and all causes can be divided into peripheral and central. The clinical signs and symptoms of bruxism are primarily characterized by temporomandibular disorders, the appearance of bruxofacets and changes in the hard dental tissues, supporting apparatus of the teeth and masticatory muscles, as well as headaches. The diagnosis of bruxism is made on the basis of anamnesis and clinical signs and symptoms, while electromyography and polysomnographic analysis are used in scientific researches. Therapy is aimed at controlling etiological factors and reducing symptoms. Occlusal splints are the most commonly used in the treatment of bruxism. Medications are used in situations when other methods, including psychotherapy, do not give positive results. Given the multifactorial etiology, the therapeutic approach must be multidisciplinary. The approach to the patient must be individual in order to treat as effectively as possible.

Research objective: to develop and implement a new clinical method of producing a set of kappa-splints for splint therapy: treatment and prevention of various forms of pathological teeth abrasion in combination with dentition defects and dentition deformations, which will enable to prevent significant disorders in the dentition.Materials and Methods: 36 patients aged 30-59 have been selected for the targeted research with a generalized form of pathological tooth wear in combination with dentition defects and dentition deformations.Results: After studying the movements of conventional hinge axis in articulate heads of TMJ with the help of condylograph «Cadiax Compact», some asynchronous, asymmetrical bias of articulate heads during the movements of the mandible were revealed in patients with pathological tooth wear in combination with dentitiondefects and dentition deformations. While examining, the patients complained about the aesthetic defects due to the abrasion of teeth and the change of their colour, the discomfort while closing, chewing and phonetic disorders. In the clinical picture of these patients, the typical symptoms of TMJ dysfunction can be singled out, such as pain and crunch in joints, fatigue of chewing muscles and pain in the muscles, the displacement of the mandible to the side during vertical movements, a feeling of fullness in the ears, headaches and bruxism. Dentition deformations were presented as a violation of the occlusal curve. The results indicate on the presence of functional TMJ disorders and masticatory muscles dysfunction in pathological teeth abrasion in combination with dentition defects.So, in most cases, temporary prosthesis structures and occlusal splints can be applied to normalize occlusive correlations at the dysfunction of TMJ and masticatory muscles. Gradual lifting of occlusion has been done due to a set of kappa-splints in terms of 14 days, 1 month and 3 months from 1.0 to 5.0 mm to the full restoration of occlusal height, depending on the severity of pathological teeth abrasion. It is the gradual application of a kappa-splints’ set which allows prevention of further tooth wear; it doesn’t influence the periodontium of teeth; it’s aesthetic and does not violate the pronunciation of sounds. The material, which a kappa-splints set is made of, provides better fixation and bite separation with optimal thickness throughout the dentition, which allows the lower jaw to take a position that helps to restore the functional balance of the entire dentition.Conclusions:1. According to the results of the research it has been established that the orthopedic treatment with the help of occlusive splints at the preparatory stage for the patients with occlusive disorders at pathological dental hard tissues abrasion in combination with dentition defects, periodontium tissue disease and dentition deformations are urgent for the normalization of occlusive correlations of the jaws.2. After studying the movements of conventional hinge axis in articulate heads of TMJ with the help of condylograph «Cadiax Compact» and eliminating the symptoms of stress in masticatory muscles of the patients with occlusive disorders at pathological dental hard tissues abrasion, it is the gradual application of a kappa-splints set, made of hard transparent plates of Ercodent Ercodur material (Germany) with a thickness of 1.0 to 5.0 mm, which allows prevention of further tooth wear, normalization of occlusive correlations of the jaws, separating a bite with optimum thickness throughout the dentition, thus the lower jaw takes a position at which the state of functional equilibrium of the entire dentition is restored.

Abstract Introduction The rapid maxillary expansion (RME) reduces the risk of developing structural and functional disorders in the stomatognathic system. Objective To examine the effects of the RME as a treatment for the posterior crossbite, related with the electromyographic activity of the masticatory muscles and the TMJ noises in a population of children. Material and method 13 girls and 7 boys, regardless of the type of malocclusion, with a mean age of 9 years old (± 3), were treated with RME. The electrovibratography analyzed the TMJ noise, and the electromyography analyzed the masticatory muscles before treatment (T0) and after three months of a short-term follow-up (T1). The comparisons of the affected and unaffected sides by the crossbite were performed using Mann-Whitney’s test, and to compare data before and after treatment the Wilcoxon’s test was used (level of significance: 5%). Result No significant differences were found in the parameters of joint noise in comparison to the sides affected and unaffected by the crossbite, in both T0 and T1 (p>0.05); only the side without the crossbite observed decrease in the peak amplitude of the joint noises after treatment. In the static electromyographic analysis, inter-side differences were observed before and after treatment, since the deliberate unilateral chewing showed greater asymmetry activity in T0 for both sides, which has been corrected after treatment, improving the functional chewing. Conclusion The proposed treatment did not lead to the occurrence of joint noises and improved the functional pattern of electromyographic activity during chewing at the end of treatment.

Examination along with implant treatment was carried out in 21 patients with severe tooth wear on the occlusal surface. This disorder features a variety of clinical symptoms including changes in the facial features and the lower jaw movement amplitude, disturbed canine and incisor guidance, supercontacts, asynchronous operation of the masticatory muscles, etc. We have proposed a treatment algorithm aimed at eliminating these issues. The temporary non-removable dentures allowed creating occlusal marks (Stage 1) followed with their transfer onto permanent orthopedic structure (Stage 2) using implants. The complexity of the approach to treating this disease, as well as the effectiveness of our method has been confirmed by clinical data and the outcomes obtained through an instrumental study involving electromyography and electronic axiography. The extra additional research methods employed, such as electromyography and electronic axiography, allowed to assess the activity of masticatory muscles and the lower jaw articulation, thus to ensure occlusal-articulation interaction when restoring the lower facial height.

Background. Joint pain is often associated not only with disc displacement but also due to the level of inflammatory mediators in the synovial fluid. Injections of platelet growth factor not only expand the joint cavity, performing a purely mechanical function but also create a high concentration of growth factor in the synovial fluid, which favorably affects the cartilage tissue, joint capsule, ligamentous apparatus. Objectives ― to study the effectiveness of platelet growth factor in the complex treatment of patients with TMJ malfunctions. Methods. A clinical examination of two groups of patients (50 people) aged 18 to 67 years with a malfunctions of TMJ was conducted. Were used in all patients in the complex: splint therapy, myogymnastics, and manual traction drive. For the first group (25 people), concentrated growth factor in the liquid phase (PRP) was used in the treatment. For the second group (PRP) was not used. The patients were divided into two groups randomly. Results. The results of the study were carried out according to the following criteria: pain in TMJ with a maximum opening of the mouth, protrusion, laterotruzii, sound phenomena in TMJ, myofascial pain (palpation), the presence of deviation/deflection of the lower jaw, incisional distance. Conclusions. 1. Complex therapy, including splint therapy, myogymnastics, manual traction of the disc, the use of platelet growth factor, showed good results in the treatment of TMJ malfunctions. 2. According to all the studied criteria (pain in TMJ with a maximum opening of the mouth, protrusion, laterotruzii, sound phenomena in TMJ, myofascial pain (palpation), the presence of deviation/deflection of the lower jaw), the most effective result of treatment was obtained after 1 month.

Active myofascial trigger points (MTrPs) in masticatory muscles are associated with a reduced range of motion and muscle weakness within the stomatognathic system. However, it is hard to identify the most effective treatment technique for disorders associated with MTrPs. The objective of this study was to analyze the acute effect of the compression technique (CT) on active maximal mouth opening (MMO) and electromyographic activity of the masseter (MM) and temporalis anterior (TA) muscles in subjects with active myofascial trigger points in the MM muscles. The study group comprised 26 women (mean age 22 ± 2) with bilateral active myofascial trigger points (MTrPs) in the MM. The control group comprised 26 healthy women (mean age 22 ± 1) without the presence of MTrPs in the MM. Masticatory muscle activity was recorded in two conditions (during resting mandibular position and maximum voluntary clenching) before and after the application of the CT to the MTrPs in MM. After the CT application, a significant decrease in resting activity (3.09 μV vs. 2.37 μV, p = 0.006) and a significant increase in clenching activity (110.20 μV vs. 139.06 μV, p = 0.014) within the MM muscles were observed in the study group, which was not observed within TA muscles. Controls showed significantly higher active MMO values compared to the study group before CT (50.42 mm vs. 46.31 mm, p = 0.024). The differences between the study group after CT and controls, as well as among the study group before and after CT did not reach the assumed level of significance in terms of active MMO. The compression technique appears to be effective in the improvement of the active maximal mouth opening and gives significant acute effects on bioelectric masticatory muscle activity. Therefore, CT seems to be effective in MTrPs rehabilitation within the stomatognathic system.

Abstract Introduction With the aging, the orofacial structures may suffer changes related to disorganization of the stomatognathic system, with a reduction in the strength and resistance of the tongue reflecting delays in the handling of the boluses in the mouth and the elevation of the hyolaryngeal complex; it may result in changes in swallowing (presbifagia or dysphagia). Changes in swallowing may be adjuvants for the illness of the elderly with great socioeconomic impact due to the high costs that bring to the public health with prolonged hospitalizations. Objectives Before it an app was created with a board game for android operating system with the possibility of training in the functions of chewing and swallowing in elderly using biofeedback. Methodology A hardware was built capable of capturing, conditioning and transmitting the electrical signal of the masseter and supra-hyoid muscles, with surface electrodes, using an interface system scan with four channels for a mobile device with Android operating system via Bluetooth. The electrical signal is received by software through a biogame, which originally held the calibration of the data, being the value range of the strength of the bite ranging from zero to 255 µV. The participant will receive the information to chew and swallow through the simulation of a “virtual farm” with the displacement of a tractor irrigating the earth which will create a plantation. The chewing cycle was standardized in 10 insect chewing’s, five for each side, ending with the swallowing. Results At the end of the game a report stating: date of the examination, consistency of the food chosen, testing time, masticatory cycles completed and incomplete, maximum and average power of bite and muscle activity of the swallowing of each side. Conclusion The application with game developed is a promising resource for training of the masticatory muscles and the swallowing of the elderly.

Subject. The state of the stomatognathic system in patients who used removable implant-retained overdentures for a period more than 4 years was analyzed by evaluating the bioelectrical activity of temporal and masticatory muscles. Objectives ― to analyze the influence of long-term usage of removable implant-retained overdentures on the dynamic parameters of the stomatognathic system by evaluating the bioelectrical activity of temporal and masticatory muscles. Methods. Clinical studies of bioelectrical activity and symmetry of the temporal and masticatory muscles using surface electromyography were carried out. Electromyography was carried out in five probes: physiological rest, occlusion, natural swallowing, clench and clench on rolls. Results. It was revealed that in a state of physiological rest and occlusion, the absolute electromyography indicators were elevated. During natural swallowing, the bioelectric activity of the muscles in patients who used removable implant-retained overdentures was characterized as reduced. During clenching and clenching on rolls, the indicators were at the level of the lower limit of the norm. It was also found that the symmetry of the temporal and masticatory muscles was below the normal level. Conclusions. The obtained data is a sign of the modified dynamic state of the stomatognathic system in patients who used removable implant-retained overdentures. In addition to changes of the bioelectric activity of the muscles, a significant violation of the symmetry of the muscles has been revealed.

This study was conducted to investigate two clinical types of masticatory muscles parafunction: teeth compression and teeth grinding using clinical and functional methods. Teeth compression and teeth grinding were found to have a common tooth compression symptom. Our finding has been proven not only through clinical, yet via electromyographic and axiographic research methods as well. Based on the obtained data we developed a palatal plate-occlusal guard. It enables to fix reliably the lower jaw and reduces muscle tension. The proposed appliance helps prevent possible complications that occur in the course of orthopedic treatment.
