Point 4 Unidose - Kerr: Bottle of 1
Point 4 optimized particle composite system is a light-cured, resin-based composite dental restorative that contains approximately 76% by weight (57% by volume) inorganic filler with an average particle size of 0.4 microns. All shades are radiopaque. Point 4 represents years of research aimed at bridging the gap between microfill and hybrid composite materials. A patented grinding process combined with sophisticated rheological modifiers allow Point 4 to polish to a very high, long-lasting luster similar to microfills, while providing strength equivalent to today's microhybrids.
