   <abstract xml:lang="ru">
    <p>Получение оттиска тканей протезного ложа при протезировании имплантационными конструкциями, особенно их протяженными типами, является важнейшей манипуляцией, влияющей на точность и пассивность прилегания протеза к имплантатам, а значит, и определяющей качество окончательного результата. Получение цифровых моделей беззубых челюстей с разным количеством опор внутриротовыми устройствами по-прежнему является нерешенной в полной мере задачей. Эргономика процесса получения модели непроста в силу необходимости как размещать в полости рта оттискные переходники, так и манипулировать вокруг них рабочей частью снимающего устройства. Точность цифровых моделей, полученных с беззубых челюстей для создания протяженных имплантационных конструкций, не превышает таковую при получении аналогового оттиска, а по данным ряда исследований, и вовсе уступает ей.&#13;
Целью работы является создание разборных оттискных имплантационных ложек повышенной до оптимума жесткости, легко разбирающихся и обеспечивающих легкий доступ к переходникам, и проведение сравнения жесткости авторских ложек цифровым способом.&#13;
Методами исследования являлась цифровая технология изучения сопротивления материала изделий и их внутренних напряжений и деформаций в программе SolidWorks (SolidWorks Corporation). Проводился анализ устойчивости конструкции к внешним нагрузкам. Нами были разработаны и созданы варианты верхних и нижних оттискных разборных ложек из жесткого и ригидного титанового сплава методом трехмерной печати по технологии DMLM на аппарате Concept Laser из титана высокой степени жесткости Ti6-Al4-V. Моделирование проведено в программе Mimics Medical 21 (Materialise, Германия) по контурам челюстной кости на основе данных конусно-лучевой компьютерной томографии. &#13;
Проведенные цифровые исследования выявили преимущественные достоинства авторских оттискных ложек.</p>

    <p>Impression taking procedure from prosthetic area in case of constructing implant supported prostheses is one of the most important steps in the process of patient rehabilitation especially in producing long span structures. Quality of the impression could affect the precision and passive fit of the prosthesis to the implants therefore the overall quality of the work.&#13;
Obtaining digital impressions of edentulous jaws with a different number of implants using intraoral devices is still an unresolved problem in full. The ergonomics of the process of obtaining an impression is not easy due to the need to place both scan abutments in the oral cavity and manipulate the working part of the intraoral scanner around them. The accuracy of digital impressions obtained from edentulous jaws for obtaining full-arch implant supported prostheses does not exceed that when obtaining a classic impression, and according to a number of researchers, it is even lower.&#13;
The aim of this study was to construct implant impression convertible trays with increased to the optimum levels of rigidity, with simple disassemble process and having an easy access to the adapters, and also to digitally compare the rigidity of the author’s impression trays.&#13;
The method of assessment was digital technology of analysing structural resistance and inherent stresses and deformations using SolidWorks software. We performed analysis of the resistance of the structure to external loads. &#13;
We have developed and created the customised copyrighted versions of the upper and lower impression trays made of rigid titanium alloy by 3D printing using DMLM technology on a Concept Laser device made of titanium Ti6-Al4-V. Modeling was carried out in the Mimics Medical 21 program (Materialize, Germany) along the contours on the data of cone-beam computed tomography.&#13;
Performed digital tests reveal the underlying advantages of the designed by authors impression trays.</p>
