Gracey curette

Area specific instrument for subgingival debridement

This type of curette has specific design created for use on certain teeth and certain tooth/root surfaces. Gracey’s curettes are named after Dr Clayton Gracey and designed in 1940’s.

They have specific design characteristics:

  • The face of the working end is tilted in relation to terminal shank at 70 degrees
  • Lower edge of the working end is sharp and used for calculus removal – working cutting edge
  • Upper edge of the working end is blunt and not used for calculus removal – non-working cutting edge
  • Long, complex functional shank

Other design features of Gracey curettes are similar to those of universal curettes:

  • Rounded toe and back
  • Semi-circular cross section

The Gracey series continues to evolve and is currently available in standard, rigid, extended shank (after five) and miniature working end versions (mini five, micro-mini five).

Gracey curette can be used to remove subgingival calculus deposits from deep periodontal pockets (PPD>5mm).

The original Gracey series contains 14 curettes. In practice, a set of three or four Gracey curettes may be enough to debride entire dentition.

Commonly used are Gracey 1&2, Gracey 5&6, Gracey 7&8, Gracey 11&12, Gracey 13&14.
