Description
このステム1の本体部3には、その表面の一部(図1中斜線で示す範囲)に凹凸が設けられた表面処理部5が形成されており、図4に拡大して示すように、その表面処理部5の表面には、ハイドロキシアパタイトの結晶6aを接着剤としての樹脂皮膜6bに含浸させた化学的結合層6が形成されている。この表面処理部5の凹凸によりステム1とステム1の埋め込まれる骨7に穿設された挿入孔8の内面との機械的結合を高めると供に、その表面の化学的結合層6に含有するハイドロキシアパタイトの結晶6aにより骨7との化学的結合を高めて、より強固にステム1と骨7とが結合するようになっている。
一方、ステップS106において、解析結果が設計条件を満たしていると判定された場合は、ステップS107へ進み、ステムデータ作成手段28によりその解析結果および設計条件を基にステム1の設計図となるステムデータを作成する。
