Hu-Friedy, Chicago, has added Gracey Curette designs to its line of EverEdge 2.0 hand instruments.
According to the company, EverEdge 2.0 was developed using a proprietary heat treatment process, as well as steel that allows for improved edge retention over the life of the instrument. EverEdge 2.0 scalers can be resharpened at any point to extend their life and value.
Gracey Curettes, a series of double-sided, area-specific instruments, can be used for removal of deposits from root surfaces. Hu-Friedy originally introduced the designs in 1945 in partnership with Dr Clayton Gracey.
The Gracey Curette blade design features one lower cutting edge, which allows adaptation to a a specific tooth surface. The blade is offset from the shank at 70° to the side, and the shank design enables the blade to be used on a specific group of teeth. According to the company, the 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.
EverEdge 2.0 instruments are available in the original EverEdge diamond-knurled, large-diameter handle, as well as the Resin 8 Colors handle, a lightweight resin handle featuring a color-coded system to easily identify scalers and curettes that correspond to areas of the mouth. The new purple grips allow for easier identification of the EverEdge 2.0 scalers in each setup.
