20140147811 | CALCIUM ALUMINATE BASED PASTE FOR STABILIZING DENTAL IMPLANTS AND RESTORING TISSUE ATTACHMENT AFTER SURGERY AND METHODS THEREFOR - 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. | 05-29-2014 |
20130236517 | Apatite Forming Biomaterial - The present invention relates to chemically bonded ceramic biomaterials, especially a dental material or an implant material. The main binder system forms a chemically bonded ceramic upon hydration thereof, and comprises powdered calcium aluminate and/or calcium silicate, and phase(s) to secure apatite formation at a pH close to neutrality. A second binder system—a cross-linking organic binder system which provides for initial crosslinking of the freshly mixed paste is advantageously added. The invention relates to a powdered composition for preparing the inventive chemically bonded ceramic biomaterial, and a paste from which the biomaterial is formed, as well as a kit comprising the powdered composition and hydration liquid, as well as methods and use of the biomaterial in dental and implant applications with the aim of remineralisation, integration and bone repair. | 09-12-2013 |
20120189987 | SIMPLIFIED CHEMICALLY BONDED CERAMIC BIOMATERIAL COMPRISING TWO BINDER SYSTEMS - 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. The inventive biomaterial is free from reactive glass and thus provides for a simplified two binder systems biomaterial with a reduced number of required reactive components The invention relates to a powdered composition for preparing the inventive chemically bonded ceramic biomaterial, and a paste from which the biomaterial is formed, as well as a kit comprising the powdered composition and hydration liquid, as well as methods and use of the biomaterial in dental and implant applications. | 07-26-2012 |
20120189983 | Calcium aluminate based paste for stabilizing dental implants and restoring tissue attachment after surgery and methods therefore - 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 a kit for preparing the paste. The invention is especially intended for re-stabilization of dental implants, and implantation into low quality bone tissue. | 07-26-2012 |
