<p>A fixture (10), which is formed from titanium or a titanium alloy and is embedded in bone (2) and osseointegrated, wherein the external surface (10S) has grooves (M) formed with a width of 10μm to 100μm and a depth of 1μm to 30μm and the external surface (10S) is formed with a three-dimensional roughness (Sa) of 1μm to 5μm. The grooves (M) are formed by irradiating while scanning laser light on the external surface (10S). The external surface (10S) is roughened by etching with acid.</p> |
