PRIMA+ is a high-end zirconia milling disc developed for precision CAD/CAM dental applications. Built on a multilayer zirconia block structure, it offers a strength of> 800 MPa and translucency ranging from 46% to 57%, ensuring both mechanical reliability and natural esthetics. The material combines Japanese TOSOH powder with proprietary fully composite technology, resulting in enhanced optical performance and stable machining behavior. Its gradient design eliminates the need for manual staining, enabling efficient production of natural-looking restorations for crowns, bridges, and full-contour prosthetics.
Translucency: 46%-57%
Strength: >800 Mpa
