Abstract: The present invention relates to a unique solution for relieving repetitive stress to dental professionals during the course of a day and is directed to sets of identical instruments, having handles made with varying diameters for grasping, designed to be used interchangeably throughout the day, thus cutting down on the repetitive grasping action through the change of grasp. Therefore, even if a dental professional uses the same type of instrument throughout the day, the hands, wrists and elbows can experience varying rather than repetitive action because the positioning of the hands, wrists and elbows are interchanging throughout the day. The dental instrument may also be ergonomically designed. Additionally, the instrument may also have a vibratory module. Further, a rotator may also be implemented.

Abstract: An active dental tool including a vibratory mechanism and a power storage reservoir. The vibratory mechanism includes an electrical motor and an elliptical load. The elliptical load is adapted to be rotated by the motor and to thereby impart an oscillatory motion to a tooth-contacting portion of the dental tool.

Abstract: The present invention relates to dental instruments used in tooth restoration and replacement including dental burs, dental discs, tapes, endodontic files, surgical drills and taps, having abrading working surfaces coated or embedded with diamond particles or chips onto the substrate or shank, the abrading surfaces having a flexible diamond-like carbon (DLC) coating. The substrate may be flexible or the shank may be made of a relatively hard substrate and diamond particles or chips may be coated or embedded onto the substrate or shank through the use of polymeric bonding agents, through embedding in a nickel or nickel alloy matrix, or through chemical vapor deposition, or even direct coating if polymeric substrates are used. The abrading surface may also be formed through the formation of cutting edges or surfaces on the substrate.
