PROBLEM TO BE SOLVED: To propose a dental implant capable of being early stabilized after implantation by including strength capable of sufficiently bearing masticatory force, and early binding properties and affinity with gum.SOLUTION: By melt-spraying and covering a core material in a state based on a melting point of calcium phosphate having a lower melting point of calcium-phosphate-based compounds by a material containing the calcium-phosphate-based compounds having different melting points, and performing hydrothermal treatment, a melt-spray covering layer covered with crystal columns in each of which acicular and/or columnar crystals of the calcium-phosphate-based compound each having a length of 2-7 μm are arranged in a prescribed direction, and a group of the crystals radially extending from the core material surface is formed.COPYRIGHT: (C)2014,JPO&INPIT【課題】 咀嚼力に十分に耐え得る強度と歯肉との早期結合性と親和性を備えることで植立後、早期安定が可能な歯科用インプラントを提案する。【解決手段】 融点の異なるリン酸カルシウム系化合物を含む材料により、芯材を前記リン酸カルシウム系化合物の内、融点が低いリン酸カルシウムの融点に基づいた態様で、熔射被覆して、水熱処理を行い、針状及び/又は柱状のリン酸カルシウム系化合物の結晶であって、長さが2μm~7μmで一定の方向に配列した結晶列、及び芯材表面から放射状に延びた結晶の集まりで覆われた熔射被覆層を形成する。【選択図】図1
