نقش پوشش های بیوسرامیکی در موفقیت ایمپلنت ها

Characterization of bioceramics coating and evaluation of the influence of kind of coating on the implantation has been developed in recent years.Different bioceramics coating like calcium phosphate, hydroxyapatite, fluorapatite and bioglass were coated on dental and orthopedic implants. In-vitro and in-vivo experiments were done for evolution of implant success and reliability and study of factors, which may influence the results.Researches indicate that different bioceramic coating may affect the bone bonding mechanism.Biodegredable calcium phosphate coating can be resorbed and be replaced with bone tissues.Hydroxyapatite cause earlier stabilization of dental implant in surrounding bone (biological fixation) and reduce healing time. Bioglass can protect substrate and provide interfacial attachment to bone.
