ABSTRACT:
An implant (prosthesis) comprises biological material in its surface intended to face the body tissue. The surface is formed of a layer (3) consisting of a mixture of grains (5) of tissue-compatible type and disintegrated tissue-compatible biological material (4).
In a method of making the implant, an implant body (2) and a mixture of grains (5) of tissue-compatible type and disintegrated tissue-compatible biological material (4) as well as a nutrient solution (6) for the latter are placed in a mould (8). The biological material is allowed to grow in the mould, both out to the boundary wall of the mould cavity and in to the implant body.
