The Surface Modifications of Dental Implants that are made of a Near-β Type Titanium Alloy

Abstract:

Abstract Titanium and its alloys are widely used as dental implant materials due to their excellent biocompatibility, mechanical properties and erosion resistance. The b type titanium alloys are becoming more promising dental implant materials for their low elastic modulus and suitable mechanical properties. Because the titanium alloys are bioinert. The dental implant’s surfaces that contact with bone tissues need modification. To bioactivate the implants, hydroxyapatite/TiO2 composite material was coated onto dental implants by sol-gel and micro arc oxidation (MAO) methods. The HA (Hydroxyapatite) was employed to enhance the bioactivity of the Ti substrate. Owning to TiO2, the HA/TiO2 composite coatings adhered tightly to the dental implants and no longer existed cracks.
