Artificial bone forming method by powder lamination method

Abstract

An artificial bone forming method, comprising a) a powder layer forming step ( 32 ) for forming, into a flat powder layer ( 6 ), a powder bone material ( 5 ) having biocompatibility and hardening by hydration, b) a partial hardening step ( 34 ) for jetting an aqueous solution ( 7 ) with biocompatibility to a part of the powder layer to harden a jetted portion ( 6 a ) by hydration, and c) an artificial bone forming step ( 36 ) for repeating the steps a) and b) for lamination to form a specified artificial bone ( 9 ) of a predetermined three-dimensional structure in which the hardened portions ( 6 a ) are connected to each other.

         10 . An artificial bone forming method by a powder lamination method, wherein the artificial bone forming method comprises:
 (a) a two-dimensional data creating step including sequentially moving a target bone in a predetermined direction to create two-dimensional data of a cut section;   (b) a tissue data processing step including creating data to be subjected to rapid prototyping for a plurality of tissues comprising a bone from the two-dimensional data; and   (c) an artificial bone forming step including forming an artificial bone comprised of a plurality of tissue structures by using a rapid prototyping device.   
     
     
         11 . The artificial bone forming method by the powder lamination method according to  claim 10 , wherein the tissue data is comprised of data corresponding to tissue selected from the group consisting of a cancellous bone, a bone trabecula, a tissue provided with a lumen, and a cortical bone.
