*** Same product, same composition, different name! The universal composite you know, Ceram.X SphereTEC One, has been renamed by the manufacturers, its new name is Neo Spectra ST HV! (High viscosity) The product is based on the advanced SphereTEC technology of a granular filler, a technology implemented under a patent.*** SphereTEC represents the process of producing micron-scale, well-defined spherical superstructures containing glass particles in sub-micron dimensions.*** The SphereTEC particle morphology, particle size distribution and surface microstructure are part of the recipe for the success of this material: unique ease of use and outstanding aesthetic results.*** Exceptional use. The new filler material technology, consisting of spherical granules together with the optimized resin matrix system, provides preferred usability features: - Easy adaptation to cavity walls - Does not stick to hand instruments - Maintains its shape, does not flow Shade A1 (= VITA® Shades A1; B1; C1) 60701981 Shade A2 (= VITA® Shades A2; B2; D2) 60701982 Shade A3 (= VITA® Shades A3; C2; D3; D4) 60701983 Shade A3.5 (= VITA® Shades A3.5; B3; B4; C3) 60701985 Shade A4 (= VITA® Shades A4; C4) 60701984
