Wise Periodontal Gracey Curette 13/14

The Wise Periodontal Gracey Curette 13/14 (Article# LS1-424) is a double-ended, area-specific instrument with two offset blades, each carrying a single lower cutting edge set at 70 degrees to the terminal shank face. The terminal shank diameter measures 1.1 mm with a 9 mm reach, and the blade measures 0.9 mm wide and 4 mm long, targeting all distal surfaces of bicuspids and molars. The perforated red silicone grip handle measures 165 mm (6.5 inches) overall, with the blade face curve following a true radius that conforms to distal root anatomy throughout the scaling stroke.

The offset single cutting edge on the Gracey Curette 13/14 self-positions against the distal root surface when the terminal shank runs parallel to the tooth, eliminating manual blade angulation during stroke activation. The upper non-cutting edge remains inactive throughout, reducing unintended soft tissue trauma during deep subgingival insertion on posterior teeth. The stainless-steel body tolerates repeated autoclave sterilization at 134°C without blade offset distortion or cutting-edge degradation across extended clinical cycles.

Dental hygienists and periodontists use Wise Periodontal Gracey Curette 13/14 during subgingival scaling, root planing, and periodontal maintenance on distal surfaces of all posterior premolars and molars. The Gracey Curette 13-14 – Acteon Satelec shank geometry allows the clinician to activate short vertical and oblique pull strokes from distofacial line angle to the midline of the distal surface, maintaining terminal shank parallelism throughout each stroke in pockets from 3 mm to beyond 5 mm depth.

Leader Surgical produces instruments that surgical teams reach for by name, a reputation built one consistent, well-manufactured tool at a time.

When should I use the 13/14 vs. the 11/12?
These instruments are often used as a pair; the 11/12 is used for mesial (front-facing) surfaces, while the 13/14 is used for the distal surfaces of the same posterior teeth.
