Optimised Particle Composite System Micro-hybrid composite for anterior and posterior restorations. Available in 16 Vita shades, 3 Xtra Light and 3 Translucent shades. Point 4 is based on Herculite and Prodigy formulations, the difference in the filler phase is that the particle size distribution is significantly smaller. The filler is fabricated using new advanced grinding technology that gives an average particle size of 0.4 microns. This smaller particle size gives a high lustre, translucency and opalescence to match dentition.
