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.

Claim (Index 16):
A method comprising:\n receiving an air supply and a water supply in a back end at a proximal end of an air driven dental handpiece device, the back end comprising an exterior port of air, an exterior port of water, and a rear air exhaust assembly, the exterior port of air configured to receive air from the air supply, the exterior port of water configured to receive water from the water supply, and the rear air exhaust assembly to expel the air out the back end, the rear air exhaust assembly comprising at least one of a plurality of exhaust air holes or a rear air exhaust port; flowing the water through a water line tube in a body and flowing the air through an air intake tube in the body, the air intake tube connecting to the exterior port of air, the water line tube connecting to the exterior port of water; powering a dental spindle using the air received at a head, the head at a distal end, the head comprising an air intake port and an air return exhaust port, the air intake port driving the dental spindle using the air, and the air return exhaust port returning the air back through the body and to the rear air exhaust assembly; blocking air leakage from the head; and expelling the air out the back end of the device using the rear air exhaust assembly.
