[Late changes in a recipient's tissues after implantation of synthetic hydroxyapatite of varying density: an experimental morphological study].

The synthetic hydroxyapatite made in Russia was applied as an insert-implant to 4 rabbits (6 eyes, 6 eviscerations). These included 2 implants having a porosity of 40% and a pore size of 0.03-1.5 microm and 2 with a porosity of 63% and a pore size of 0.05-3.0 microm. The hydroxyapatite that is made in Russian and that has preferably a porosity of 40% and a pore size of 0.03-1.5 microm can be successfully used to make a locomotor stump after removal of the eyeball. The hydroxyapatite having these parameters more rapidly intergrows around the periphery with fibrovascular tissue and its vascular components mainly reduce by month 8. Our data suggest that the synthetic hydroxyapatite made in Russia may be used in ophthalmological care.
