    摘要: The surface of a bone implant disposed with a plurality of grooves (20) along its longitudinal axis or at a sharp angle thereto which form an angle null radial the longitudinal axis (41) of the implant body (11) in at least one of multiple sections (16) and have different depths across their lengths. Said grooves may be configured in wedge or diamond shape or take the form of a curved wedge (231) or of elongated curved segments (251) of varying depths across their lengths and extending in axial, spiraling or crosswise-coiling manner relative the perimeter of the implant. Such a configured surface structure affords an improved deposition of bone tissue osteons. A titanium layer sputtered on the implant surface allows for osteocytes to collect in the troughs thereby created. The surface structure can be utilized preferably in the case of tooth implants but also in other bone implants including those having curved longitudinal axes.
