ABSTRACT:
A method to impregnate a porous bone replacement material (1) with a liquid impregnating agent (5), whereina) the bone replacement material (1) is or will be enclosed in a chamber (2) with two openings (3, 4) that can be closed,b) the impregnating agent (5) is introduced into the chamber (2) until the bone replacement material (1) is at least partly immersed in the impregnating agent (5),c) one of the two openings (3, 4) will be closed,d) the chamber (2) is evacuated at least partly via the other, open, opening (4, 3), so that the air contained in the pores of the bone replacement material (1) is at least partly removed from it,e) the vacuum produced in the chamber is terminated again by supplying air or a gas through one of the openings (3, 4), andf) the vacuum produced in the pores of the bone replacement material (1) is terminated by the impregnating agent (5) penetrating into the pores of the bone replacement material (1) immersed into the impregnating agent (5).
