Synthetic and Biological-Derived Hydroxyapatite Implant Coatings.

This document discusses the use of hydroxyapatite (HA) coatings for orthopedic and dental implants. HA is a bioceramic material that enhances fixation and osseointegration at the implant-tissue interface. The document highlights the advantages of using biodegradable implants, such as eliminating the need for a secondary surgical intervention. It also explores the use of synthetic and biological-derived HA, with the latter showing enhanced mechanical performance and bioactivity. Various techniques for coating implants with HA are discussed, including plasma spray, pulsed laser deposition, and biomimetic coating. The document concludes by emphasizing the focus on the synthesis and characterization of HA-based coatings for applications in bone repair, tissue engineering, and dental implants.
