17/18 Gracey Curette, Small, DE Terminal shank is 3mm longer than Standard Gracey. Compared to the standard Gracey curette, blade is 50% shorter and 10% thinner. Good for scaling in deep, narrow pockets. The last pair of Gracey Curettes is 15/16 and 17/18 Gracey Curettes. They are useful to solve the problems hygienists had reported with access into particularly awkward spaces. 15/16 Gracey Curette allow improved mesial access, and 17/18 Gracey Curettes allow improved distal access to areas which even the complex curvature of the 11/12 Gracey Curettes and 13/14 Gracey Curettes have proved unable to reach satisfactorily. The 15/16 has the same exaggerated terminal shank design as the 13/14, but the blade is finished like an 11/12. This exaggerated angle helps correct positioning on harder to reach mesial molar surfaces. The 17/18 also has the same extreme angle, but also a longer terminal shank and reduced blade length to improve access to the distal surfaces of posterior teeth.
