<p>PURPOSE:To accomplish strong and long-lasting bond with own bones by furnishing through holes from the own bone conjugate side to the base material conjugate side while increasing the dia. gradually, and allowing the surface on the base material side to be missing partially. CONSTITUTION:Through holes 9 are provided from the own bone conjugate side of a living body bone-affinity member 8 to the base material conjugate side of a substitute bone in such a way as increasing the dia. gradually. The surface of this member 8 on its base material side is left partially missing so as to form a groove 10, and thereby openings at the base material conjugate side are put in mutual communication between one or more adjoining ones. When osteoblasts intrude into these through holes 9 and a new-born bone is formed, it works as if anchor to fix the substitute bone and own bones together firmly.</p> |
