Gracey Curettes STANDARD GRACEY CURETTE Originally designed to be finishing curettes for fine scaling and root planing, Gracey Curettes were developed in the 1940’s by Dr. Clayton Gracey in coordination with Hugo Friedman, the founder of Hu-Friedy. Each Gracey Blade is offset at 70˚
Wider
Standard vs. Rigid SG1/2R
and has one cutting edge—the lower edge. The combination of this unique blade and 9 different shank designs for specific tooth surfaces provide improved adaptation and deposit removal in scaling procedures.
Rigid & Extra Rigid Gracey • Shank diameter is wider than Standard Gracey Curette • Blade width is the same as standard Gracey Curette • Rigid: Used for moderate to heavy calculus removal • Extra Rigid: Used for tenacious calculus removal
Standard Gracey SG1/2
Instrumentation: The blade of a Gracey Curette is correctly adapted when the lower cutting edge is against the tooth, and the terminal shank is parallel to the tooth surface being scaled. Apply lateral pressure against the tooth (root) and pull upward, maintaining the parallel shank.
• The blade is offset from the shank at 70°. This creates one cutting edge which is referred to as the lower edge. • Gracey Curettes are used in a set to completely scale the dentition.
