Abstract:
The present invention provides an air driven dental handpiece device with a back end configured to receive an air and water supply; a handpiece body having an air intake tube and a water line tube carrying air and water respectively through the device; and a head receiving air to power the device's dental spindle. The head securely blocks air from leaking and returns the air through a large air return exhaust port back through the inside of the body and out a rear air exhaust assembly including a plurality of exhaust air holes and/or an air return exhaust port. The device helps eliminate a patient's sensitivity and discomfort, helps eliminate the risk of surgical air emphysema, as well as helps eliminate any cross contamination during oral surgical procedures.
