7/10 Straight Chisel, 15-20

Clinical Use

7/10 Straight Chisel, 15-20 is a restorative hand chisel, built with a straight (non-curved) bi-bevel blade at a 15mm/20mm profile, for direct-access margin work. It trims unsupported enamel and refines the cavo-surface margin at the edge of a cavity preparation, a hand-controlled step that follows rotary preparation and leaves a cleaner, more precisely angled margin than a bur alone typically achieves.

This margin-finishing step matters most in anterior restorative work, where the cavo-surface angle affects both the marginal seal of the finished restoration and its visible appearance at the tooth surface.

Design and Handling

The bi-bevel blade is ground on both sides of the cutting edge, giving a centered, symmetric cut that doesn’t pull toward one side of the preparation the way a single-bevel edge can. The handle is balanced for the light push-cutting stroke restorative chisel work calls for, distinct from the heavier striking use of a surgical bone chisel.

SurgiWorld’s Restorative Chisels are stocked as their own category, distinct from the surgical bone chisels used in oral surgery – a restorative operatory needs the lighter Wedelstaedt bi-bevel profile for enamel margin work, not a heavier striking instrument built for bone.

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, corrosion resistant and rated for full autoclave sterilization without losing edge or tip definition over repeated cycles.
