A bone fixing implant is provided to secure good biocompatibility without rejection and to activate tissues by using composite ceramic used for an outer layer. A bone fixing implant(10) having a hollow inside is composed of threads(12) formed on the outer surface of a body(11); a conical flange(15) of which an upper end is tapered downward; and a polygonal head unit(16) formed at the upper part of the flange. The body comprises inner and outer layers(13,14). The thickness of the inner layer is one third or two thirds of the thickness of a radius of the body. One of the inner and outer layers is made of composite ceramic and the other is made of plastic. The outer and inner layers are integrated. |
