Appearance and character being approximate to the organism bone, it offers the artificial bone which is superior in bone conduction talent and bone induction talent. The sponge bone and/or to extract the part which is suitable to the adrenal cortex bone in three dimensional graphics data of the organism bone which is digitalized, (the figure 1 (a))The extraction process which sets the centerline (the figure 1 (b))The picture formation process which forms the artificial bone graphics data by drawing even diameter or the beam or the wall of wall thickness with, alongside the aforementioned centerline, (the figure 1 (c))With, on the basis of the aforementioned artificial bone graphics data, the laser you sinter the metal powder, modelling process and the alkali which accumulate sinterring layer after processing, you heat, alkali after processing, before the heating deviation from alkali it does that the process which is heated simultaneously with deviation from alkali is had or according to need and or it features.外観的にも性質的にも生体骨に近似していて骨伝導能及び骨誘導能に優れた人工骨を提供する。デジタル化された生体骨の三次元画像データにおいて海綿骨及び/又は皮質骨に相当する部分を抽出し(図1(a))、中心線を設定する抽出工程(図1(b))と、前記中心線に沿って一様な直径又は肉厚の梁又は壁を描くことにより、人工骨画像データを形成する画像形成工程(図1(c))と、前記人工骨画像データに基づいて、金属粉末をレーザー焼結し、焼結層を積み重ねる造形工程と、アルカリ処理した後、加熱する、又は必要に応じてアルカリ処理した後、加熱前に脱アルカリしもしくは脱アルカリと同時に加熱する工程とを備えることを特徴とする。
