Abstract: The present invention generally relates to the use of pre-formed bodies of Chemically Bonded Ceramics (CBCs) biomaterial for implantation purposes wherein the bodies are prepared ex vivo allowing process parameters to be optimized for desired long term properties of the resulting CBC biomaterial. More particularly, the pre-formed CBC material bodies of the present invention are sintered. The pre-formed body of CBC material is machined to the desired geometry and then implanted using a CBC cementation paste for fixation of the body to tissue. The invention also relates to a method of preparing pre-formed bodies of CBC biomaterial for implantation purposes, methods of preparing an implant thereof having desired geometry, and a method of implantation of the implant, as well as a kit for use in the method of implantation.

Abstract: The present invention relates to a calcium aluminate based paste forming a chemically bonded biomaterial on hydration thereof for in vivo anchoring of new implants, or stabilizing of existing implants in situ to an adjacent bone tissue, which paste provides a controlled pH value and temperature as well as initial hardening time. By virtue of the pH value and temperature the paste exhibits antibacterial and/or bacteriostatic properties. The present invention also relates to a method of preparing implants to be implanted wherein the implant is coated with the paste, a method of implanting a coated implant, as well as methods of preventing and treating implant related conditions, such as periimplantitis, and kit for preparing the paste. The invention is especially intended for re-stabilization of dental implants, and implantation into low quality bone tissue.

Abstract: The present invention generally relates to chemically bonded ceramic biomaterials, preferably a dental material or an implant material, comprising two binder systems. The main binder system forms a chemically bonded ceramic upon hydration thereof, and comprises powdered calcium aluminate and, optionally, minor amounts of calcium silicate. The second binder system is a cross-linking organic binder system which provides for initial crosslinking of the freshly mixed paste forming the biomaterial. The biomaterial also comprises inert filler particles.
