Research Abstract

Thermally induced liquid-phase deposition method was developed to produced a thin hydroxyapatite (HA) film on a porous surfaced titanium oral implant in a calcium phosphate solution. It was also demonstrated that osteoconductive properties of HA film was most likely attributed to its buffering action in inflammatory tissue with low pH when the implant was inserted into bone.
