Abstract

Improvements are provided for a dental air abrasive system (10) of the type which utilizes a compressed gas or air (12) which creates a gas stream. Abrasive particles are introduced into the gas stream and expelled out through one end of a nozzle (24) whereupon the abrasive laden gas stream impinges upon the target, i.e. tooth amalgam, composites, stain and/or tooth dental filling materials. The improvements include the use of tow (22, 28) or more hoppers each containing different sized abrasive particles, which are selectively fed, either together or independently of each other, into the gas stream.
Different sized abrasive particles are provided in each hopper for cutting different types of tooth structures. Other improvements include the use of fluorescent and/or colored abrasive particles lo facilitate the aiming process, a laser beam, strobe, white light or other illuminating means for aiming the abrasive stream and/or illuminating the target area as well as a disposable nozzle for hygienic reason.
