ABSTRACT:
A method and apparatus for an air abrasive unit such as those used in the dental field. This method and apparatus utilizes an internal vibrator motor with vibration transmitters which transmit the vibrations throughout the abrasive jar. The abrasive pickup assembly uses pressure differentials to suck up abrasive through a screen which controls the flow rate and particle size of the abrasive flowing through the system. This system can utilize a photo optical detection system to detect the abrasive level. Alternatively, a pressure/pulse detection system may be used to measure abrasive level. Dilution of the air/abrasive mixture and "air only" modes are possible with the present system. Depressurization and mere reductions of pressure can also be accommodated.
