28 Distal Margin Trimmer

28 Distal Margin Trimmer – Double-Ended Gingival Margin Trimmer (SKU R6-2298)

The NNA Medical 28 Distal Margin Trimmer is a double-ended gingival margin trimmer designed for bevelling and planing the distal gingival cavosurface margin of Class II (proximal box) cavity preparations. Its curved blades and angled cutting edges reach the gingival floor of the proximal box so you can finish the enamel margin cleanly and precisely, without damaging the adjacent tooth. Distal-pattern trimmers are also commonly used to bevel or round the axiopulpal line angle of the preparation.

Made from surgical-grade stainless steel and finished with a diamond-knurled, non-slip handle, this distal margin trimmer gives excellent tactile control during margin refinement. It is fully autoclavable and built for years of daily use in restorative and operative dentistry. The instrument number and SKU are engraved on the handle for quick identification on the tray.

Key Features

• Double-ended design – two working ends on one instrument for complete access around the distal margin.
• Curved blades with angled cutting edges – shaped specifically for bevelling gingival enamel margins.
• Surgical-grade stainless steel – corrosion resistant, holds a sharp cutting edge and is fully autoclavable.
