From contacts and bondings between bone and bioactive glass to bonding of bioactive glass and porcelain to metal alloys, different methods of fracture repair.

Bioactive glass has the ability to bond to bone. In this article the contact between glass and bone is discussed and the development of core alloy for an implant coated with bioactive glass and the oxidation of metal surface in ceramic fusion has been studied. Good bonding of coating materials to core alloys is necessary in dental implants. Using a pull test method we studied the bond strengths between various alloys and some composite materials clinically used to repair fractures of porcelain-veneered dental crowns. An experimental bioglass material was also studied. The bonding of composite materials to metal surfaces etched with hydrofluoric acid was almost as good as the bonding between metal and porcelain, or glass.
