Abstract

A grinding disk has a pilot region or ring that does not include abrasive material. The pilot region aids in positioning the disk between teeth or in other orientations. The disk may be used in conjunction with a guard. For example, the guard may include grip enhancements such as finger plates or cups. Guards can accommodate contra-angles. Guards made of transparent plastic improve work area visibility for a dentist or user. Some guards are made of plastic and are disposable. Embodiments of the guard may include a lubrication port for introducing a lubricant to the disk. The port may include an orifice in a wall of the guard. The port may also include a tube, for guiding the placement of a lubricating hypodermic needle and/or a hose barb for communication with a lubrication source via tubing. A disk stop in the guard can position the disk for receiving lubricant.
