Product Description: Honchon 4D plus Multilayer Zirconia Blank
Honchon 4D plus Multilayer Zirconia Blank is our premium-grade zirconia solution, designed to achieve the perfect balance of esthetics and strength. This disc features a seamless transition in color (from cervical dark to incisal light), strength (ranging from 1200 MPa to 750 MPa), and translucency (from 43% to 57%) — all within a single blank.
Thanks to its smart gradient structure, the 4D plus Multilayer zirconia is ideal for both anterior and posterior restorations. Whether it’s a highly esthetic front tooth or a load-bearing bridge, this one disc handles it all.
Crafted for high-performance CAD/CAM systems, Honchon zirconia ensures smooth milling, precise fitting, and exceptional aesthetic outcomes. Its pre-sintered softness allows effortless shaping while maintaining outstanding edge stability and minimal wear on tools.
