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.
L'invention concerne un système destiné à un matériau d'obturation dentaire ou à un matériau d'implant, en variante un système permettant de lier, respectivement, une dent ou un os à un matériau d'obturation dentaire ou à un matériau d'implant. Ce système comprend un liquide d'hydratation à base d'eau et un matériau en poudre, la phase liante du matériau en poudre étant essentiellement constituée d'un système de ciment à base de calcium. Ledit matériau en poudre peut, après saturation avec le liquide, réagir avec la phase liante afin d'hydrater un matériau céramique lié chimiquement. Selon l'invention, ledit matériau en poudre et/ou ledit liquide d'hydratation comprend un phosphate soluble dans l'eau ou une phase pouvant former un phosphate soluble dans l'eau, ce qui permet au système de pouvoir former de l'apatite pendant l'hydratation. L'invention concerne également ledit matériau en poudre et ledit liquide d'hydratation tels quels, un matériau d'implant et un procédé de liaison.
