The three basic parts of a bur are the head, the neck and the shank. Dental restorative burs are typically made from tungsten carbide or a diamond particle coating of varying degrees of roughness depending on the purpose of the bur, bonded to the underlying metal bur head. Ceramic burs are also available and are used for dental restorative procedures. They can be used for caries removal. Surgical burs are fabricated from tungsten carbide.
Most often used for: Cutting through porcelain, polishing.
