  • Patent number: 5967779
    Abstract: An abrasion hand piece for use with an air abrasion system to perform dental procedures. The hand piece is adapted for connection to the air abrasion system by a hose and has a body member which allows tips to be releasably attached thereto. The releasable tip feature allows the body member to be used with a number of different tips, thereby reducing the number of tools that the dentist must have on hand and must sterilize between procedures. The tips have an outer coating which is softer and warmer to the patient when placed in the mouth. The outer coating is color coded so that the orifice size of the tips may be readily identified. An illumination device is attached to the hand piece to allow the dentist to better monitor the procedure and to provide for aiming the hand piece at the desired tooth area.
