Abstract
An endosseous implant having a mesh pore structure including at least an embedding portion to be embedded in a living bone tissue, the embedding portion being a single sheet of a platelike body or a desired shape of body obtained by working the platelike body. The platelike body can be a single metal mesh sheet or a laminate of a plurality of metal mesh sheets formed into one body by mechanical bonding or by sintering, the laminate having a multiplicity of mesh pores passing through the embedding portion, whereby the embedding portion provides a mesh pore structure adapted to permit into the mesh pores the ingrowth and penetration of a fibrous tissue along out of three kinds of bone, osteoid, and fibrous tissues or not less than two tissues inclusive of the fibrous tissue.
