Hydroxyapatite (HA) largely consists of calcium and phosphorous. This composition allows HA to function in the biomedical industry as a coating that promotes osseointegration between bone and various orthopedic implants.
HA is so often used in hip, knee and other implants and as a synthetic bone substitute because it allows for cement-less implants and it helps promote bone ingrowth. Many reports suggest that HA coatings precipitate faster bone fixation and a reduction of pain and recovery time for implant patients. Hydroxyapatite can also be used as an equally effective coating in the dental implant industry.
HA Bio Coatings
The advantages of using hydroxyapatite as a bio implant coating over more traditional coatings are typically seen as negligible at first. It is over an extended period of time that the benefits of hydroxyapatite coatings become clearer. As time passes, dental and orthopedic implants coated with hydroxyapatite show a greater success rate in terms of the overall function of the implant. Hydroxyapatite coatings and titanium coatings are unique in that they are capable of connecting structurally and functionally with human bone.
Hydroxyapatite is becoming increasingly popular as an implant coating. And, the biomedical industry has demonstrated a tremendous level of confidence in APS’ ability as a provider of hydroxyapatite coatings.
