Abstract

Work is devoted to research of influence of morphology of a surface porous implants on their adhesion to bone tissue.

Material of researches - porous samples in diameter 8 and height 12-14 mm from spherical and spongy powders of technically pure titan. The average of pore sizes 120-160 microns, porosity 0,42-0,56.

Samples were implanted in bone tissue by a laboratory animal and in terms 1, 3 and 6 months left together with near bone fragments. Durability of coupling implants with a bone was investigated, and also preparations for histologic researches prepared. The effect of influence of a condition of a surface of particles of the titan on process of growing - ingrowth bone tissue is established. In case of ideally smooth spherical particles bone tissue simply fill pore space, being kept in it mainly due to an interlacing and jamming in the goffered pores. Only in case of spongy particles with a rough and microporous surface bone tissue form close intimate
