A new prosthetic concept, today available under the name CeraOne™, for single tooth replacement with the Brånemark system is described. This concept is characterized by a new design of the prefabricated components. A mechanical torque driver is used together with a gold screw and a special counter-torque device to ensure that the screw is tightened in an optimal manner to resist screw loosening and only transmit minor stress to the fixture interface. Another characteristic is the use of a prefabricated cap of sintered aluminum oxide as the basis for the ceramic crown. The crown is cemented to provide better esthetic possibilities even in situations of somewhat unfavorable fixture placement. Schlagwörter: abutment, single tooth implant, titanium
