DENTAL IMPLANT AND SURFACE TREATMENT METHOD OF DENTAL IMPLANT

摘要

PROBLEM TO BE SOLVED: To provide an implant that has macro pores having an inner diameter with the level of several tens of μm and micro pores having an inner diameter of 1-2 μm while having pores with the nanometer level in the surface.;SOLUTION: The implant has the surface that has the macro pores having the inner diameter with the level of several tens of μm and micro pores having the inner diameter of 1-2 μm and comprises nano discharge craters having an inner diameter with the level of several tens of nm. The surface treatment method includes steps of producing the macro pores having the inner diameter with the level of several tens of μm by acid treatment of the surface; producing the micro pores having the inner diameter of 1-2 μm by blast treatment of the implant surface; and producing the nano discharge craters having an inner diameter with the level of several tens of nm by anodic oxidation treatment of the implant surface.;COPYRIGHT: (C)2012,JPO&INPIT
