  • Dental Drill - an overview

    They are normally made of stainless steel, diamond grit or particles, and tungsten carbide and fitted to a dental drill incorporating an air turbine. The dental bur was developed <300 years ago [8] and still widely used. The dental bur [4,8,9] has three parts: the head, the neck, and the shank. The head contains the blades, which produce cutting action by rotary motion.
