Electrospun PVP Fibers as Carriers of Ca Ions to Improve the Osteoinductivity of Titanium-Based Dental Implants.

Although titanium and its alloys are widely used as dental implants, they cannot induce the formation of new bone around the implant, which is a basis for the functional integrity and long-term stability of implants. This study focused on the functionalization of the titanium/titanium oxide surface as the gold standard for dental implants, with electrospun composite fibers consisting of polyvinylpyrrolidone and Ca ions. Polymer fibers as carriers of Ca ions should gradually dissolve, releasing Ca ions into the environment of the implant when it is immersed in a model electrolyte of artificial saliva.
