<p>Sport, as a socially active branch of human activity, undergoes its changes towards progress, every year an increasing number of different sports and the number of adherents of an active lifestyle. Currently, to prevent injuries of the maxillofacial region, used in sports sports dental tires (kappa).</p><p> We have developed a new design of sports tires dental and its technology. The resulting construct sports tires holds the lower jaw in the right position at the moment centric load; facilitates the distribution of high blood pressure, preventing hypertonicity masticatory muscles; does not violate the diction and facial aesthetics; so there is no barrier of communication. Use of this sports mouthguard can significantly stabilize the craniomandibular system in adverse conditions for it, and will also ensure the prevention of diseases of hard tissues of the teeth, periodontal and TMJ and significantly reduce the risk of pathological changes in the dentition. </p>

Objective. To develop the bionic ear prosthesis design and a method for its manufacture based on intellectual and medical 3D technologies. Materials and methods. Taking into account the analysis of data from domestic and foreign literature, a bionic ear prosthesis and a device for its manufacture have been developed. During the implementation of the project, digital equipment and software were used. The developed design of a bionic ear prosthesis consists of several components, including an auricle prosthesis and a sound processor inserted into it. This provides the functionality of remote control, configuration and wireless charging. The system is based on the principle of bone conduction. The auricle prosthesis is an external attachment device with high aesthetic characteristics, made of biocompatible materials using modern digital technologies. Built-in hearing aid, includes a microphone; a sound processor based on a digital signal component with built-in analog-to-digital and digital-to-analog converters; Bluetooth radio channel module for communication with the settings control device (Android smartphone); and an emitter of sound vibrations. Results. The expected positive effect is to increase the effectiveness of treatment, rehabilitation and socialization of deaf and hard of hearing patients by reducing the volume of surgical intervention; prevention of postoperative complications; the use of a rational aesthetic design of the auricle epithesis made of biologically compatible materials, with an inclinated highly functional electronic hearing aid integrated with the patient's auditory environment. Conclusions. The combination of these factors can provide a significant reduction in the terms of medical and social rehabilitation of patients of different ages. In addition to the above, a significant advantage of the developed design of a bionic prosthesis and the method of its manufacture is ease of use and economic availability.

Цель исследования - разработка и оценка эффективности экспериментальной модели периимплантита, как осложнения при дентальной имплантации. Методика. Предложена экспериментальная модель для изучения процесса формирования осложнений (периимплантита) после дентальной имплантации. Периимплантит моделировали на белых крысах в 2 этапа. На первом этапе 50 крысам экстрагировали первый моляр верхней челюсти слева. На втором этапе осуществляли имплантацию. Использовали модели - импланты, изготовленные не фабричным способом из чистого титана. Животные были разделены на 2 группы. Основную группу составили 25 крыс с моделированием периимплантита. Периимплантит моделировали путем создания нестабильности положения импланта за счет наложения лигатуры из хлопковой нити на область его шейки. Группу сравнения составили 24 крысы с установкой импланта без моделирования условий для формирования периимплантита. Результаты. Приведено подробное описание модели эксперимента. Результаты оценивали через 12 нед после имплантации. В основной группе периимплантит развился у 86,4% животных (19 из 22), в группе сравнения у 17,4% (4 из 23). Заключение. Предложенный способ является эффективной экспериментальной моделью для формирования периимплантита, что позволяет использовать ее для изучения патофизиологии формирования и оценки различных методов профилактики и лечения данного осложнения. Aim. To present an experimental model of complications following dental implantation (peri-implantitis). Methods. Peri-implantitis was modeled on white rats (n=50) in two steps. At the first step, the first molar was extracted from the left side of the upper jaw. At the second step, the implantation was performed. Non-commercial implants made of pure titanium were used. The animals were divided into two groups. The main group consisted of 25 rats with peri-implantitis modeled by creating instability of the implant position by ligation of the implant neck area with a cotton thread. The comparison group (n=24) consisted of rats with an installed implant without modeling peri-implantitis. Results. A detailed description of the experimental model was provided. The outcome was evaluated at 12 weeks after implantation. In the main group, peri-implantitis developed in 86.4% of rats in the experimental group vs. 17.4% in the comparison group. Conclusion. The suggested method is an effective experimental model of peri-implantitis, which allows studying the pathophysiology of peri-implantitis and evaluating different methods for prevention and treatment of this complication.
