CAD/CAM

Spectrum Dental Laboratories uses the latest CAD/CAM technology to meet increasing demand for restorations with clinically proven strength, exceptional beauty, and uncompromising aesthetics and vitality that replicates the beauty of natural dentition. CAD/CAM Zirconia restorations produce some of the strongest and most aesthetic all-ceramic crowns and bridges to date.

With ytrria stabilized Zirconia (or YZ for short) restorations, dentists no longer sacrifice aesthetics for the strength of conventional PFM restorations. Thanks to its high strength values, zirconium based restorations can be adhesively or conventionally cemented.

Since they have to withstand high chewing forces, posterior all-ceramic bridges were contraindicated for a long time. YZ’s outstanding strength (>900 MPa) fulfills clinical requirements related to masticatory forces, particularly in the posterior region.

At Spectrum Dental Laboratories we have extensively researched the all-ceramic systems available on the market today and selected two of the leading systems that meet the criteria of most milled Zirconia substructures and eliminate the challenging task of shade adjustment. Our goal was to find a ceramic system that would complement different framework materials. We narrowed the list down to two. Our first selection is the VITA PM®, the latest restorative material in the PM line with small particles and excellent wear rates. Our second selection is the IPS e.max® Ceram, a new material generation based on nano-fluorapatite that provides restorations with optimal natural appearance. Both systems enable our technicians to consistently produce beautiful, high-strength restorations of all types.

As an alternative to conventional veneering, both systems can be pressed onto zirconium frameworks, which allows Spectrum Dental Laboratories technicians to fabricate the conventional inlay-retained bridge in a minimally invasive fashion using all-ceramic. VITA PM® and IPS e.max® Press may also be pressed without the support of a zirconium substructure for the fabrication of single or multi-surface inlays, onlays, partial crowns, veneers, and anterior crowns using the staining/glazing or layering technique.
