Gracey #9/10 Long contra-angle for molar buccal and lingual surfaces. More pronounced angle than 7/8 for less accessible root surfaces.
Gracey curettes are area-specific to allow for deep scaling, root planing and periodontal debridement. They have an offset blade which provides a perfect working angulation for the tooth surface. Offset blade angulation means only the lower cutting edge of each blade is used.
