The implant body which is embedded to a bone and carries out osseointegration has slots 1 um to 1 mm wide on the outside surface. The abutment body which carries out fitting to the central hole of the implant body has slots 1um to 1 mm wide on the outside surface. The depth of the slots is 1 nm to 1 mm. The cracks are formed in the inside of the slots. The slots are formed by laser scanning.本發明之埋入骨內而進行骨整合之植入體於外表面具有幅度形成為1μm以上1mm以下之溝。嵌合於植入體之中心孔之支台體於外表面具有幅度形成為1μm以上1mm以下之溝。溝的深度為1μm以上1mm以下。溝之內面形成裂縫。溝是照射雷射光並且掃瞄而形成。2‧‧‧齒槽骨4‧‧‧牙齦5‧‧‧植入物6‧‧‧人工牙冠8‧‧‧支台體8S‧‧‧外表面10‧‧‧植入體10S‧‧‧外表面12‧‧‧公螺絲S‧‧‧抵接部
