The RTD LIGHT-POST™ combines the most modern aspects of translucency and radiopacity with the 2-stage taper design that made our fiber posts world-famous. Made from Quartz fibers , the LIGHT-POST™ is available in 3 sizes, each of which has a corresponding end-cutting Pre-Shaping drill and a side-cutting Finishing drill. Its overall design is tapered, to conserve tooth structure, and is comprised of two cylindrical sections, which provide maximum surface area for bonding and maximum bulk for strength.
