Abstract

Some kinds of ceramics are being successfully used in clinic practice and showed biocompatible and bioactive behavior. Under highly loaded condition titanium metals are used but they need to be coated for the protection of human body from extraction of titanium ions and ill effect. The concept of coating metal implant surfaces with hydroxyapatite (HA) ceramic coatings combines the mechanical benefits of metal alloys with the compatibility of HA. Titanium metals coated by HA ceramic coatings show the high bone-bonding ability as well as high fracture toughness and biocompatibility. However adhesion of apatite layer leaves to be improved. To improve the adhesion between coating and implants in this study titanium implants have been covered with two layers. The titanium oxide layer has been produced by electrochemical oxidation that provides the strengthening and high adhesion of the oxide layer to the metal. Then oxidized surface has been covered by calcium-phosphate containing layer when using ceramic technology or in electrochemical process. It has been found that the composition and structure of the implant surface strongly influence its bioactive properties. Different ratio of mixture of different dispersity HA and bio glass provides the formation layer having different levels of porosity and pores' size upon heat treatment. Thus the implant bioinductivity and bioconductivity could be controlled.
