Пористые сплавы никелида титана (TiNi), благодаря своим уникальным свойствам сверхэластичности и биосовместимости, находят широкое применение в медицине и используются в качестве костнозамещающих имплантатов, однако длительное ручное изготовление и невозможность создания точной геометрии существенно ограничивают их клиническое применение. В реконструктивной хирургии при замещении костных дефектов необходимы биосовместимые эндопротезы индивидуальной формы и сложной геометрии. Применение пористых 3D-TiNi имплантатов может стать решением многих проблем в области травматологии и костной онкологии.</p></sec><sec><title>Цель</title><p>Цель: оценка возможности применения пористых 3D-TiNi имплантатов в остеопластических операциях на основе исследования структуры и биосовместимости материала в условиях in vivo.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. Пористые образцы в виде конусов и индивидуального имплантата для челюстно-лицевой хирургии были получены методом селективного лазерного плавления из порошка TiNi. Для печати индивидуального имплантата для челюстно-лицевой хирургии использовали персональные данные пациента НИИ онкологии. Макроструктуру, элементный и фазовый состав пористых образцов никелида титана исследовали методами растровой микроскопии и рентгеноструктурного анализа.

Структурные исследования пористых образцов TiNi показали, что методом селективного лазерного плавления можно получить сквозную пористую структуру с прочными контактными перемычками между частицами порошка трехфазного состава. В результате испытаний in vivo имплантатов в виде конусов не наблюдалось местных воспалительных изменений, отторжения и деформаций осей задних конечностей лабораторных животных. Показана принципиальная возможность изготовления индивидуального имплантата сложной геометрии из порошка TiNi методом селективного лазерного плавления, по данным МСКТ больного.</p></sec><sec><title>Выводы</title><p>Выводы. Пористые 3D-TiNi имплантаты, полученные методом селективного лазерного плавления, показали высокую биосовместимость в условиях in vivo. Экспериментальное исследование подтвердило эффективность и простоту применения 3D-TiNi имплантатов, их отличную самофиксацию в костной ткани, а также аугментацию костной ткани на границе с имплантатом. Выявлено, что макроструктура, химический и фазовый состав материала имплантата близки к традиционным пористым сплавам TiNi. Показано, что метод селективного лазерного плавления позволяет создавать сложные геометрические дефекты костных тканей из TiNi.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Porous TiNi alloys are widely used in medicine as osteoreplacement implants due to their unique properties of superelasticity and biocompatibility, but their clinical use is severely limited by time-consuming manual fabrication and the inability to create precise geometries. Reconstructive surgery for the replacement of bone defects requires biocompatible endoprostheses of individual shape and complex geometry. The use of porous 3D-TiNi implants can be a solution to many problems in traumatology and bone oncology.</p></sec><sec><title>Aim</title><p>Aim: To evaluate the possibility of using porous 3D-TiNi implants in osteoplastic surgery based on a study of the structure and biocompatibility of the material under in vivo conditions.</p></sec><sec><title>Material and Methods</title><p>Material and Methods. Porous samples in the form of cones and a single implant for maxillofacial surgery were prepared from TiNi powder by selective laser melting. To print an individual implant for maxillofacial surgery, the personal data of the patient at the Oncology Research Institute were used. The macrostructure, elemental and phase composition of porous titanium nickelide samples were investigated using scanning microscopy and X-ray diffraction analysis. The biocompatibility of porous cone-shaped samples was evaluated in vivo using guinea pigs whose condition was analysed by CT scanning.</p></sec><sec><title>Results</title><p>Results. Structural studies of porous titanium nickelide samples showed that selective laser melting can be used to obtain a continuous porous structure with strong contact bridges between particles of a three-phase powder. In vivo testing of the cone-shaped implants showed no local inflammatory changes, rejection or deformation of the hind limb axes of the experimental animals. The basic feasibility of fabricating a custom implant of complex geometry from TiNi powder using selective laser melting according to a patient’s MSCT data was demonstrated.</p></sec><sec><title>Conclusions</title><p>Conclusions. Porous 3D-TiNi implants obtained by selective laser melting showed high biocompatibility under in vivo conditions. An experimental study confirmed the efficacy and ease of use of 3D TiNi implants, their excellent self-fixation in bone tissue, and bone tissue augmentation at the interface with the implant. The macrostructure, chemical and phase composition of the implant material was found to be close to traditional porous TiNi alloys. It was shown that the method of selective laser melting makes it possible to create complex geometric defects in bone tissue from TiNi.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>никелид титана</kwd><kwd>микроструктура</kwd><kwd>пористый 3D имплантат</kwd><kwd>биосовместимость</kwd><kwd>остеопластика</kwd></kwd-group><kwd-group xml:lang="en"><kwd>titanium nickelide</kwd><kwd>microstructure</kwd><kwd>porous 3D implant</kwd><kwd>biocompatibility</kwd><kwd>osteoplasty</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">исследование выполнено за счет гранта Российского научного фонда № 22-72-10037, https://rscf.ru/project/22-72-10037/.</funding-statement><funding-statement xml:lang="en">The study was supported by the Russian Science Foundation grant No. 22-72-10037, https:// rscf.ru/project/22-72-10037/</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Zhu J., Zeng Q., Fu T.
