摘要：
The invention relates to medicine, namely to orthopedic devices for dental implantation of dental prostheses.The technical result provided by the claimed solution utility model is to provide a structure that ensures reliable connectable bone and soft tissue to the outer surface of the porous implant, cost reduction and application processing method providing guaranteed chemical purity porous structure.The cylindrical implant structure is made of a titanium alloy TB6 to the outer surface in the form of a helix, on which are formed elements mikroretentsii a microporous with a porosity of 60 ÷ 70% of the surface formed by blind holes quasi-spherical shape with a diameter of 80 ÷ 140 microns and a depth of 60 ÷ 100 microns, disposed tightly to each other. A porous surface structure is formed by plasma electrolytic anodic etching in an electrolyte with a content of 2% ammonium fluoride NH 4 and 3% by weight of NaO 4 in distilled water with the addition of a chemically passive powder is calcium phosphate Ca 3 (PO 4)2, the particle size of which is determined microgeometry porous structure. A plasma electrolytic etching implant preform is carried out at a constant current with a density of 2A / dm 2 at a voltage of 32 ÷ 36 V at a temperature of 25 ÷ 30 ° C with an exposure of 30 ÷ 40 ° C, a particle removing Ca 3 (PO 4)2 of the porous structure producing etching solution of 3% by weight of sodium fluoride NaF and 2% by weight of hydrochloric acid HCl in distilled water.1 s.p.formuly 1 ZP f-ly.Изобретение относится к области медицины, а именно к ортопедическим стоматологическим устройствам для имплантирования зубных протезов.Техническим результатом обеспечиваемым заявляемым решением полезной модели является создание конструкции, обеспечивающей надежность соединяемых костных и мягких тканей с внешней пористой поверхностью имплантата, снижение себестоимости и применение способа обработки, обеспечивающего гарантируемую химическую чистоту пористой структуры.Цилиндрическая конст
