Abstract

FIELD: medicine. SUBSTANCE: method involves applying a four-layer coating system to titanium base of implant, having two titanium or titanium hydride layers of differing thickness and dispersity degree, the third layer made of mechanical mixture of titanium or titanium hydride and hydroxyapatite in 60-80% by mass to 20-40% by mass proportion, respectively, and an external hydroxyapatite layer. To reach high mechanical strength implant properties, layer-by-layer spraying process is carried out under various modes to provide smooth transition from compact titanium structure to biologically active layer structure. EFFECT: improved biocompatibility properties; long service life as tooth root implants. 1 dwg

Используется в ортопедической стоматологии для изготовления внутрикостных имплантатов. Сущность изобретения: на титановую основу имплантата методом плазменного напыления наносят систему покрытий из четырех - двух слоев титана или гидрида титана различной дисперсности и толщины, третьего слоя из механической смеси титана или гидрида титана и гидроксилапатита с соотношением соответственно 60 - 80 мас.% и 20 - 40 мас.%, и наружного слоя - гидроксилапатита. Для повышения механической прочности имплантата напыление ведут послойно при различных режимах, обеспечивающих плавный переход от структуры компактного титана к структуре биоактивного слоя. Благодаря идеальной биомеханической совместимости с костной тканью предлагаемый имплантат выполняет роль "вечного" корня зуба.Used in orthopedic dentistry for the manufacture of intraosseous implants. The essence of the invention: on the titanium base of the implant by plasma spraying, a coating system is applied from four to two layers of titanium or titanium hydride of various dispersion and thickness, the third layer from a mechanical mixture of titanium or titanium hydride and hydroxylapatite with a ratio of 60 to 80 wt.% And 20 to 40 wt.%, And the outer layer is hydroxylapatite. To increase the mechanical strength of the implant, the deposition is carried out layer by layer under various conditions, providing a smooth transition from the structure of compact titanium to the structure of the bioactive layer. Due to the ideal biomechanical compatibility with bone tissue, the proposed implant acts as an “eternal” root of the tooth.
