Summary
Titanium is the reference material for dental implants, but it does not itself stimulate the formation of new bone around the implant - the very process on which long-term stability depends. This study functionalises the titanium/titanium oxide surface with electrospun composite fibres of polyvinylpyrrolidone carrying calcium ions, designed to dissolve gradually and release Ca2+ into the implant environment when immersed in artificial saliva. Scanning electron microscopy, energy dispersive X-ray spectroscopy and ATR-FTIR confirmed that the coated fibres formed as intended, and electrochemical measurements followed the behaviour of the interface over time, supporting the use of the fibre coating as a route to osteoinductivity.

The PVP/Ca2+ fibres were produced on a Starter Kit-Random device (Linari Engineering S.r.l., Pisa, Italy), operated at 10.02 kV with a flow rate of 1 ml/h - the entry-level complete station for randomly oriented nanofibres, whose control unit is coded HVG-CONT-LCD.
