Prima Dental Group has commercialised the new AccuPrep tungsten carbide bur with Predator AccuPrep. Crown and bridge preparation has traditionally used diamond tipped burs, and Prima has developed a parallel product with its tungsten carbide fluted drills. These burs deliver a faster, more efficient cut and better preparation surface.
With the minimum of clogging for precision, with less friction and therefore little heat generated, Prima's AccuPrep burs match the most popular diamond patterns, so you need not change your technique.
