  • System for a dental filling material or implant material, and powdered material, hydration liquid, implant material and method of achieving bonding
    Patent number: 7699925
    Abstract: A system for a dental filling material or an implant material, alternatively a system for bonding between a tooth or a bone and a dental filling material and a implant material, respectively, which system comprises a water based hydration liquid and a powdered material, the binder phase of which powdered material essentially consisting of a calcium based cement system, which powdered material has the capacity following saturation with the liquid reacting with the binder phase to hydrate to a chemically bonded ceramic material. According to the invention, said powdered material and/or said hydration liquid comprises water soluble phosphate or a phase that has the capacity to form water soluble phosphate, whereby the system exhibits the capacity during hydration to form apatite. The invention also relates to the powdered material and the hydration liquid as such, an implant material and a method of achieving bonding.
