21B Cone Burnisher, 2.7mm/3mm, Black Non Stick

Clinical Use

21B Cone Burnisher, 2.7mm/3mm, Black Non Stick is a finishing-stage instrument, built with cone-shaped tips at 2.7mm and 3mm with a black non-stick coating. It’s reached for after a restoration – composite, amalgam, or a metal crown margin – has already been placed, to smooth and adapt the material against the tooth surface rather than to shape or place it.

The rounded ball or cone tip burnishes rather than cuts: run along a margin or occlusal surface, it closes small gaps, smooths transitions, and knocks down minor high spots left behind by the placement or carving instrument, without removing material the way a carver’s edge would.

Design and Handling

Two tip sizes on a single double-ended handle mean a fine margin adjustment and a broader smoothing pass are both available without reaching for a second instrument. The polished, rounded tip surface is shaped to glide rather than dig in, giving consistent, controlled pressure across the restoration surface.

SurgiWorld’s Burnishers range covers ball, acorn, cone, and Ladmore tip patterns across several sizes, so the right burnishing profile for a given margin or occlusal surface is always available on the finishing tray.

SurgiWorld supplies this instrument to dental clinics, restorative practices, and dental schools across Canada and the USA, backed by fast replacement stock so a worn or lost instrument doesn’t leave a gap in the tray setup.

Material and Sterilization

Manufactured from medical-grade stainless steel with a black non-stick coating that keeps composite and bonding material from clinging to the blade during placement and sculpting, fully autoclavable and rated for repeated sterilization cycles.
