Abstract
The metal implants with helicoid carving and rough or smooth polished surfaces (3S, Israel) were administrated in tibial proximal condyle of not purebred rabbits. At 2 and 6 months after intervention the bone tissues from implantation places were investigated by method of light microscopy. In all cases the edges of bone tissue had minimal scar changes, and both types of metal articles connected to bone densely. Implants were delimited from red and yellow bone marrow structures by thin layer from different types of connective tissue. Morphological symptoms of an inflammation and merge of macrophages in multinuclear cells weren't detected in one supervision. However the very small metal fragments were observed in tissues near both types of articles in isolated cases. Considerable microscopic differences of bone tissue condition after implantation of rough or polished metal articles weren't found. Also essential distinctions of condition of tissues around implants between in 2 and 6 months were absent after administration of each article type.
