The modification of polytetrafluoroethylene surface using hydroxyapatite coating deposited by RF-magnetron method

The ossteointegration rate of the polytetrafluoroethylene (PTFE) dental implants is related to their composition and properties of surface. Osteoconductive calcium phosphate coatings promote bone healing and apposition, leading to the rapid biological fixation of implants. The deposition of the hydroxyapatite (HA) coating on the PTFE surface by the RF magnetron sputtering method and the influence of this modification on the wettability, and physicochemical properties are presented in the present work.
