Since their introduction into dentistry in 2001, zirconium oxide materials have remained the strongest material class for tooth-coloured indirect restorations, while consistently improving in translucency and overall aesthetics. High strength and low minimum wall thickness make them an excellent choice for implant-based restorations, which need to withstand high chewing forces, due to a lack of tactile feedback for the patient. While dedicated blocks for chairside CAD/CAM fabricated implant restorations have been available before, they were not yet able to benefit from the aesthetic improvements of zirconium oxide formulations with higher translucency or multilayering. In response to the needs of dental practitioners, Dentsply Sirona is launching CEREC Cercon 4D Multidimensional Zirconia Abutment Block, an aesthetic zirconia abutment block with more than 1100 MPa strength, 0.5 mm minimum wall thickness and a new, proprietary, three-dimensional layering technology.

Conventional multilayer zirconia blocks are constructed from several horizontal layers. As this does not fully reflect the contouring of dentine and enamel in natural teeth, the new, highly aesthetic CEREC Cercon 4D CAD/CAM zirconia block is designed with three-dimensional layering that includes a dome-shaped dentine core with a higher pigment content and opacity, and a more translucent enamel contour. This results in more natural aesthetics that mask the TiBase and match the VITA shade. Time as the ‘fourth dimension' comes into play through an efficient milling and sintering workflow with CEREC Primemill and CEREC SpeedFire and makes the CEREC Cercon 4D abutment block a real ‘4D' experience. But CEREC Cercon 4D Abutment Block does not stop there, as it also is the world's first aesthetic zirconia meso block that offers 2-in-1 versatility, as it is indicated for both screw-retained crowns and custom abutments. The high strength of more than 1100 MPa of its 4Y-zirconia also allows for a minimum wall thickness of just 0.5 mm for restorative treatments in areas with limited space.

Due to differences in the approval and registration times, not all technologies and products are immediately available in all countries.
