Abstract

The invention relates to a trace element selenium slow-release type artificial tooth root based on a nanometer tube array surface. A layer of sodium titanate nanometer tube array layer is formed on the surface of a metallic titanium base body of the artificial tooth root, and a trace amount of sodium selenite and bone morphogenetic protein are loaded in the sodium titanate nanometer tube array layer. A preparation method of the trace element selenium slow-release type artificial tooth root based on the nanometer tube array surface comprises the following steps: adopting pure titanium or titanium alloy for processing the artificial tooth root; then, adopting the two-step anodic oxidation technology for obtaining a titanium dioxide nanometer tube array layer with the tubular structure on the surface of the pure titanium or titanium alloy artificial tooth root; next, converting the titanium dioxide nanometer tube array layer into the sodium titanate nanometer tube array layer through an alkaline solution hydrothermal synthesis technology; and finally, loading a trace amount of sodium selenite and bone morphogenetic protein into the sodium titanate nanometer tube array layer on the surface of the artificial tooth root by a centrifugal load technology.

Description

technical field [0001] The present invention relates to a trace element selenium sustained-release artificial tooth root based on the array surface of nanotubes, in particular to a sodium titanate nanometer material composed of pure titanium or titanium alloy artificial tooth root matrix and loaded with trace element selenium and bone morphogenetic protein. An artificial tooth root composed of a tube surface layer and a preparation method thereof belong to the technical field of artificial tooth root materials. Background technique [0002] Dental implants are internationally recognized as the first choice for restoration of missing teeth. They are similar to real teeth in terms of function, shape, and use effects, and can be called "artificial teeth." Dental implants are composed of artificial tooth roots and porcelain crowns. Pure titanium and its alloys are widely used in the manufacture of artificial tooth roots for dental implants. However, ordinary titanium dioxide la...
