Abstract: A system of treating teeth or associated tooth structure using an abrasive-laden fluid stream provides fluid at high pressure to a manifold with selectively operable valves to deliver fluid at a selected pressure to a mixer for the fluid and abrasive and delivery to a device for application to a patient's mouth. Priming air at low pressure pressurizes the mixer. An alternate air path bypasses the mixer. A selective control delivers a stream of fluid or fluid and abrasive to the tooth or tooth structure. Upon termination of treatment, pure air is diverted through a purge line to purge the system of abrasive. A vacuum is selectively operable to remove abrasive and debris from the mouth during and after the abrasive treatment. The abrasive delivery device includes a hand-held nozzle having ports operable by the fingers for control. The vacuum includes a rigid, disposable collection chamber for sterile disposal of the abrasive and debris and has a common filter for the purge circuit and for removal of abrasive and debris from the mouth. Connection to the dental office suction system or a water powered venturi provides suction. Pressure regulation and relief insures instantaneous change from one pressure level to the next.

The laser assembly includes a housing having a cavity in which a pulsed laser in contained. The laser is excited so that the laser emits a laser beam along a predetermined axis that is in line with a fiber optic delivery system and at a pulse rate of one to 10,000 pulses per second and an average power variable from one tenth to 50 watts. A handpiece is dimensioned to be inserted into a human mouth while an optical fiber optically connects the laser output to the handpiece. The laser assembly also includes a continuous output aiming laser which, upon activation, provides a continuous laser aiming beam coaxial to the treatment beam. Both beams are then introduced into a fiber optic delivery system.

Abstract: Improvements are provided for a dental air abrasive system of the type which utilizes a compressed gas or air which creates a gas stream. Abrasive particles are introduced into the gas stream and expelled out through one end of a nozzle 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 two 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 to 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 reasons. Other improvements include the use of a vacuum evacuation system to minimize dusting of the abrasive particles, as well as a dam removably positioned within the patient's mouth which reflects the abrasive particles back towards the evacuation system. Still other improvements include the use of a microvalve adjacent the nozzle which, when closed, terminates gas flow through the fluid passageway in order to further minimize dusting of the abrasive particles.

Abstract: A combination air abrasive system and laser system are provided for dental applications. The air abrasive system creates an abrasive material laden gas flow and then directs this gas flow towards a target site in the patient's mouth. The air abrasive system also includes a vacuum system which creates an air flow to remove the abrasive material after impingement on the target site. The abrasive material is filtered from the air flow and the resulting clean air is then used to create a positive pressure within the housing for the dental laser system to prevent the entry of debris and other contaminants within the laser system. Additionally, the clean air flow is used to clean the lens system for the laser. Also, the air abrasive system and laser system include a common control system and may also utilize a common aiming and illumination mechanism. Further, the combination unit has a common light source that not only illuminates the target area, but can be used as a curing light for dental materials, which light source may or may not be a laser. Further, the combination unit has a single common footswitch that allows the performance of more than one task.
