Artificial bone forming method by powder lamination method

摘要

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.
