title: Hydroxyapatite coatings in implant dentistry.
abstract: Hydroxyapatite coatings have shown promise due to the enhanced integration of osseous tissues to coated implant surfaces. When compared with healing around commercially pure or titanium alloy implant surfaces, hydroxyapatite-coated implants appear to be superior in sites which are compromised in either quantity or quality of bone. In spite of these encouraging findings, the long-term stability of the hydroxyapatite/bone interface has been challenged. Microbiologically, the hydroxyapatite-coated implant surface may be at an increased risk to bacterial plaque. However, after 8 years of clinical utilization, the hydroxyapatite-coated implant surface has not been shown to be predisposed to increased long-term failure. Available research as it pertains to this controversial area of implant dentistry is reviewed.
