Aim. Development of an algorithm for forecasting the shape and size of dental arches in view of the teeth size and the major maxillofacial parameters. Materials and methods. The materials of the research were the results of measurements of the cephalometric parameters and diagnostic gypsum models of the dentition series of 103 people of the first period of adulthood with a complete set of permanent teeth, physiological occlusion and various gnathic and dental types of the face and dental arches. To determine the dental type of face (normodontia, macrodontia, microdontia), the diagonal dimensions of the facial head were evaluated between the cephalometric points t (tragion) and sn (subnasale). When establishing the gnathic type of face (mesognathy, dolichognathy, brachygnathy), the gnathic index was calculated, calculated as the percentage of diagonal and transversal dimensions of the facial part of the head. Transversal dimensions represented the width of the face between the goat-bearing landmarks t-t. Gnathic variants (mesognathy, dolichognathy, brachygnathy) of dental arches (Dmitrienko S.V., 2015) were determined taking into account the dental index calculated as the ratio of the half-sum of the width of the crowns of 14 teeth to the width of the dental arch between the second molars. The types of the dental system (normodontia, macrodontia, microdontia) were determined from the results of summation of the width of the crowns of the upper teeth. Results. As a result, an algorithm was proposed for forecasting the shape and dimensions of the dental arches, which is based on measuring relatively stable parameters, namely, the dimensions of the anterior teeth and the basic features in the maxillofacial area. The algorithm is based on mathematical calculations of the circle geometry and the dependence of the length of the arch, chord and height. The circle diameter was calculated as the ratio of the dental arch width between the canines to the sine of the central angle shaped by the radii of the circle limiting the chord. The size of the front-canine diagonal is comparable to the size of the front teeth in a certain ratio. Conclusion. Optimization of diagnostic and treatment methods for adult patients with anomalies of the dentoalveolar system not only makes it advisable to revise the conventional traditional diagnostic regimens for determining the shape and size of dental arches in order to increase the effectiveness of orthodontic treatment, but also implies the expansion of existing modern ideas about the morphology of the craniophatic complex and its relationship to the shape, the size of the dental arches. in clinical orthodontics, the introduction of a forecast algorithm based on the measuring the relatively stable parameters will reveal the deviations in the teeth location as well as in the shape and size of the upper dental arch in the transversal and sagittal planes, reducing the time spent in the early diagnostics phase and increasing the effectiveness of monitoring the outcomes of orthodontic correction.

A clinical study involving 120 patients revealed multidirectional disorders of microbiocenosis in patients with dental diseases in the form of reducing the number and metabolic activity of indigenous microflora, increasing the activity of aerobic flora, in particular with proteolytic activity (caries), and increasing the activity of optional and residual anaerobic microorganisms in inflammatory periodontal diseases. This was manifested by violations of the quantitative and qualitative composition of shortchain fatty acids with isomers and other calculated parameters in saliva. Changes in these parameters were aggravated by the increase in the severity of inflammation and correlated with the results of clinical indicators. During the period of the therapy with Stomatidin, positive changes in the microbiocenosis of the oral cavity were noted, which are expressed in increasing the number and activity of the obligate microflora, reducing the activity of optional and residual microorganisms.

Lichen planus is a nodular chronic disease that occurs on the skin and visible mucous membranes and has the character of a lichenoid reaction that is characterized by a polymorphism of symptoms of clinical manifestation, a severe, prolonged, recurrent course. Erosive-ulcerative and hyperkeratotic forms of the disease are an optional precancer with a malignancy probability of up to 7 %. In the local treatment of erosive ulcerous forms of lichen planus, it is promising to use in the local treatment a drug combining anti-inflammatory, keratoplastic, analgesic, antifungicidal and antibacterial properties. In the local treatment of erosive ulcerous forms of lichen planus, it is promising to use in the local treatment a drug combining anti-inflammatory, keratoplastic, analgesic, antifungicidal and antibacterial properties. The clinical case of collagen biodegradable drugs shown in the article showed a good clinical result, which requires further study of the effectiveness of these drugs in the complex treatment of diseases of the oral mucosa in order to optimize dental care for this group of patients

The article considers the use of ultrasonic bone surgery in dentistry and maxillo-facial surgery, provides a brief review of the literature. The authors presents the indications and advantages of using this technique for bone preparation. Also describes the applied aspects and explains the most efficient, according to the author, using the method of piezosurgery in the practice of an oral surgeon.

Postoperative rehabilitation of patients with perforated forms of odontogenic maxillary sinusitis includes rational orthopedic treatment. However, during the surgery using traditional methods, such as oro-antral fistula closure using vestibular muco-periosteal trapezoidal flap are unavoidable complications - reduction in the depth of the vestibule of the oral cavity and the amount of attached gingiva, which requires preprosthetic surgical training. We have proposed a method of oro-antral fistula closure, which prevents the development of the above complications and decreases the period of postoperative rehabilitation.

For several years, actively discussed the issue of standards in dentistry. Materials and methods evolve constantly. New methods and technologies demand from dentists to be in line with the up-to-date level of science and assure the patients with treatment, which meets the rising requirements of population. The last 15 years, musculo-articular TMJ occupies the third place after caries and periodontal disease among lesions of the oral system. The share of muscle pain is 97 % of all cases of chronic orofacial pain and can be mistakenly attributed to odontogenic pain. Because of ignorance of the essence of the problem, the diagnosis is limited to ascertaining atypical pains, which results in inadequate and more ineffective treatment. The introduction of the botulinum toxin type A standard in a comprehensive dental treatment plan in patients with myogenic dental syndromes minimizes the risks of complications in the treatment process, and cases of improper prescribing by doctors are excluded.

A clinical study of the effectiveness of occlusive disorders correction and periodontitis and masticatory muscles hyperfonus treatment via electroneurostimulation, grinding, laser and anti-inflammatory therapy, and bioreparation. 73 patients with periodontitis and hypertonus of the masticatory muscles with occlusive disorders were treated. it was found that combined treatment significantly reduces the time of treatment and leads to rapid relief of periodontal inflammation.

The study compared the various types of maxillary sinus by cone beam computed tomography. Sinus pneumatization was identified after extraction of maxillary posterior teeth in 90 % of cases, the sclerotic type of maxillary sinus was discovered after radical maxillary sinusotomy (Caldwell-Luc). The comparative analysis of various methods of radiodiagnosis set that cone beam computed tomography can get helpful information for planning the treatment and predict the result of sinus-lift surgery and dental implantation.

Prevention of bone atrophy in the area of the tooth to be removed is one of the components of the success of dental implantation. This tactic consists of atraumatic removal of the tooth, as well as in carrying out the technique of preservation of the holes with osteoplastic material. In this article, the successful experience of using the domestic demineralized bone material Xenograft Collagen of Cardioplant Co. with the preservation of the holes of the remote teeth is given. The quality of the bone obtained is estimated after four months by 3D-modeling and histologically.

A computer analysis of the telediography of the head in the lateral projection using the Dolphin Imaging program was performed in eight patients aged 18-35 years with gnathic mesial occlusion. The results of cephalometric analysis showed that two patients were shown to perform a surgical operation on the lower jaw. Complex orthodontic treatment in combination with orthognathic surgery in patients after 18 years allows us to normalize not only the aesthetics of the face and the smile, but also the vital functions of biting and chewing food, swallowing, speech, breathing.

A comprehensive examination of 30 patients was carried out, of them 5 patients had a history of chronic hyperplastic candidiasis, 7 had salivary gland diseases, 5 had a hyperplastic process while taking medications from the group of nifedipine, 5 people were diagnosed with Leukemia, 5 patients noted in an anamnesis chronic administration of cyclosparin. Dental status was determined during the examination and conduct of an index assessment of the mucous membrane of the oral cavity. For the statistical analysis of the material studied, MS Excel 2003 spreadsheets were examined. In patients with chronic hyperplastic candidiasis, the hyperplastic process and the periodontal pathology were diagnosed in all. In 74.2 % of the presence of tartar, soft plaque, in 54.2 % of the mobility of teeth II degree. When examining patients with a hyperplastic process against a background of long-term use of medications, an inflammatory process in the gum area, periodontal pockets with an outgrowth in 60 % was noted. Dentility was determined in 65 % of teeth. In the group of people with salivary gland diseases, 100 % complained of discomfort and bleeding gums. Periodontal pockets have been revealed in 100 % of patients with severe hemorrhagic exudate. The index of hemorrhage in hypertrophic processes on the background of long-term use of drugs was 2.12 ± 0.15. When assessing the periodontal index in patients with hyperplastic process and salivary gland diseases, generalized periodontitis of medium degree was found in 40 %, severe in 60 % of the patients.
