<p>The invention relates to a dental implant which can prevent peri-implantitis and in which an affinity of a jawbone embedded portion embedded into the jawbone with the jawbone is not degraded. In a dental implant (10), at least a region (12a) of a gingiva contacting portion (12) which is in contact with gingiva (D), is antibacterially treated, and an arithmetic average roughness Ra of an outer surface of the region (12a) is set to 2 µm or less. At least the region (12a) of the gingiva contacting portion (12) has antibacterial properties, and becomes such a surface texture that bacteria are less prone to attach to and stay in the region, and the region is prone to be in close contact with the gingiva (D).</p> |
