<p>A dental implant comprising a cylindrical core material and a recrystallized apatite-based ceramic coating layer, said coating layer being adhered to at least a part of the outer peripheral surface of the core material, wherein the coating layer is configured to be a hydrothermally treated plasma spray coating which is formed by plasma-spraying a composite material, said composite material comprising two or more kinds of calcium phosphate-based compounds having different melting points, toward the outer periphery surface of the core material on the basis of the melting point of a calcium phosphate-based compound having a lower melting point among the calcium phosphate-based compounds. This dental implant has such a strength as being sufficiently tolerant to masticatory power over a long period of time, a quick bonding ability to the gingiva and a high affinity therefor. Moreover, the dental implant has an excellent drawing strength.</p> |
