STUDI KEKUATAN ADHESI DAN APATITE INDUCTION ABILITY PADA PELAPISAN HYDROXYAPATITE PADA TITANIUM

Metallic biomaterials (titanium and titanium alloys) have been widely employed in many load-bearing orthopaedic applications, as they have excellent mechanical properties and corrosion stability. However, soaring problems such as a lack of direct chemical bonding between the implant and host tissues leading to implant loosening still persist. To prevent this problem, surface modifications such as applying hydroxyapatite onto titanium is necessary. The aim of this study is to investigate and to compare the bond strength and apatite induction ability of the hydroxyapatite coated titanium
