Clearfil Majesty Posterior is a light-cure, nano-superfilled, radiopaque restorative composite resin composed of nano and micro inorganic filler treated with a proprietary new surface coating technology. The new surface technology permits a larger quantity of nanofiller to be dispersed in the resin matrix, a matrix which consists of monomer and microfiller. Clearfil Majesty Posterior has an improved high surface hardness very close to that of human enamel (high wear resistance), high mechanical strength, high durability, high depth of cure, extremely low polymerization shrinkage and very low thermal expansion coefficient. These features assure a reliable posterior restoration with better marginal adaptation and a restoration that will last. In spite of the extremely high filler loading, Clearfil Majesty Posterior also has a very shapeable consistency and the high refractive matrix also provides another essential benefit, a very minor transparency shift after light curing.
