Titanium Bases CAD/CAM Crown and Bridge Restorations

11 TITANIUM BASES CAD/CAM FOR CROWN AND BRIDGE RESTORATIONS FABRICATION OF CROWNS AND BRIDGE RESTORATIONS ON CAMLOG ® AND CONELOG ® TITANIUM BASES CAD/CAM The rotation-locking cam of the titanium base CAD/CAM, crown, for single crown restorations, should in each case be aligned in palatal/lingual direc- tion. This ensures maximum wall thickness of the restoration on the ves- tibular side. The undercut of the rotation-locking cam is splinted with a suitable material. The surface to be scanned is coated with Scanspray. The titanium base CAD/ CAM can then be scanned using current dental scanners and the digitally captured geometry used in the fabrication of single crown or bridge resto- rations with CAD/CAM techniques. USE OF SIRONA PRODUCTS CAMLOG ® and CONELOG ® Titanium bases CAD/CAM crown, are compati- ble with Sirona's CEREC System and can be selected in the CEREC software. The scan is performed with a mounted Sirona Scanbody, optionally on the titanium base CAD/CAM crown, or on a CAMLOG ® or CONELOG ® ScanPost for Sirona Scanbody. Scanbodies from Sirona Dental Systems GmbH are available separately for different camera systems in various connection sizes. Information about the Sirona Scanbodies and their use is available from Sirona Dental Systems GmbH. FABRICATION OF A CROWN AND BRIDGE RESTORATION After fabricating the cast, the CAMLOG ® or CONELOG ® Titanium base CAD/ CAM is placed in a corresponding lab analog and fixed hand-tight with the corresponding bonding aid. Optionally, the titanium base can also be fixed hand-tight in the lab analog with the corresponding lab screw using a screwdriver, hex. The titanium base must be seated in the lab analog cor- rectly. The rotation-locking cam of the titanium base CAD/CAM, crown, for single crown restorations, should in each case be aligned in palatal/lingual direc- tion. This ensures maximum wall thickness of the restoration on the vestib- ular side. NOTE The procedures for processing of the components described in the follow- ing, the fabrication of a single crown and bridge restoration on titanium bases CAD/CAM and subsequent bonding, is identical for CAMLOG ® and for CONELOG ® .
