Clinical Use

The burs, cutters, abrasives and polishers in this collection are used to trim, shape and finish acrylic dentures, provisional crowns and bridges, bite trays and other plastic appliances. Nearly all items have an HP shank for the straight laboratory handpiece; carbide and steel cutters remove bulk material, and the abrasives, polishers, brushes and buffs smooth and polish afterwards.

Care and Reconditioning

Clean, disinfect and sterilize the burs, abrasives and polishers between uses following the manufacturer instructions, and replace an instrument once it loses cutting or polishing performance or shows damage. Our Dental Bur Reprocessing & Sterilization Guide covers the workflow for Busch rotary instruments; maximum speeds are in the Dental Bur Speed Chart.
