Role of Hydroxyapatite (HA) Coatings in Implants : A Review
Abstract
Biomaterials are the materials that are used for the restoration and reorganization of various tissues as well as organs. Some of the common materials presently used are organic, metallic, and composites. To increase the biocompatibility of these materials, some types of coatings are regularly applied. Hydroxyapatite is one of the materials which is mostly used for coating these materials. Hydroxyapatite acquires the same structural and chemical characteristics as human bone. In the present review, we discussed the various aspects of hydroxyapatite coatings that consist of rationale, coating process, various techniques, and coating failures.
