PERIODONTAL GUIDE

Gracey Curettes — the complete numbering, types & technique guide

Numbering, four type variations, two systems that change how your Gracey performs, the right handle for your hand, and clinical technique — all in one place.

Numbering — what fits where

  • 1/2, 3/4 — Anterior, all surfaces
  • 5/6 — Anterior & premolars
  • 7/8, 9/10 — Posterior buccal & lingual
  • 11/12, 15/16 — Posterior mesial
  • 13/14, 17/18 — Posterior distal

Four types — pick the right geometry

  • Standard (Classic) — routine SRP, moderate pockets
  • Mini Gracey — narrow pockets, furcations, maintenance
  • Rigid Gracey — heavy or tenacious calculus
  • Titanium (blue) — peri-implant maintenance, won’t scratch implants

Two systems — applied on top

  • ErgoRazor® — sharpness system, 440C cryogenic steel, 3× longer edge
  • ErgoTip® — modular system, replaceable working tips, no sharpening
  • Available across every type and number

Five handles — choose your comfort

  • ErgoX® — silicone, 11.5 mm
  • ErgoX® Plus — silicone, 13.65 mm (larger grip)
  • ErgoSteel Standard — stainless, 9.5 mm
  • ErgoSteel Plus — stainless, 10 mm
  • ErgoLite X — lightweight resin over steel

Technique — the 5 fundamentals

  • Modified pen grasp for control
  • Establish a stable fulcrum
  • Lower shank parallel to tooth surface
  • Short overlapping strokes
  • Sharpen at first sign of dullness — or use ErgoRazor / ErgoTip

From budget-friendly to premium

  • Same ErgoDenta build quality across the range
  • Designed in Denmark · CE / EU-MDR / FDA / UKCA
  • Fully autoclavable — instruments and handles

UNIVERSAL VS GRACEY

How does this curette compare across families?

Universal and Gracey curettes solve different clinical problems. The blade angle, edge count and intended pocket depth tell you which to reach for at the chair.

Universal curette working end — 90° blade, two cutting edges

Universal Curette · 90°

Both edges sharpened. Adapts to multiple surfaces with one instrument. For supragingival and light subgingival scaling.

Gracey curette working end — 70° offset blade, single cutting edge

Gracey Curette · 70° offset

Single lower edge sharpened. Area-specific. For deep subgingival pockets and definitive root planing.

Quick rule: Universal for routine recall prophylaxis and shallow pockets · Gracey for moderate-to-deep periodontal pockets and area-specific root planing. Most kits hold both.
