| 20090029324 | Methods and Devices for Fixed Dental Restoration - This invention relates to methods and devices for restoring teeth using fixed restorations. In particular, the invention provides a system, kit, and devices for the management of interproximal areas for traditional cementation and/or bonding of dental crowns, onlays, inlays, veneers and bridges. In the method, a barrier is positioned in contact with the tooth being restored and an adjacent tooth to cover a section of the tooth being restored and to create separation of the tooth being restored and the adjacent tooth. Cement is applied to the first mating surface of the fixed restoration and/or to the second mating surface of the tooth, and the first mating surface of the fixed restoration and the second mating surface of the tooth are positioned adjacent each other to seat the fixed restoration on the tooth. The barrier covers a section of the tooth being restored to prevent cement from bonding to the section of the tooth. This eliminates the need to remove hardened cement from this section of the tooth. | 01-29-2009 |
