In an artificial bone that is custom-made medical equipment, there is a trend that artificial bone transplantation has increased compared with autologous bone transplantation because of its safety and less-invasive. However, there are some problems in a metallic artificial bone such as titanium used for load part: (a) The toughness and strength of the metallic artificial bone is much higher than the one of the autologous bone, (b) In the joined part to the human bone part, loosing occurs because uniting with the bone is weak, (c) QOL of patient is low after surgery of mandibular reconstruction. Because, fixation with plate is not shape rebuilding but only functional restoration and there is no custom-made artificial bone for the bone part where a defect has occurred. In order to be solved the above object, the technique for producing custom-made medical equipment consists of biomaterial and based on CT image data corresponding to a shape of the artificial bone has been developed by the metal laser-sintering hybrid milling method which enables a complex shape parts to manufacture with one process and one machine.
