ABSTRACT:
An air driven dental handpiece having means for securing a dental bur and means for supplying a rotative power to the dental bur. The power is supplied, in the preferred embodiment, by an air turbine. The handpiece includes an air supply conduit within the handle, with a conduit furnishing the air to supply the rotative power to the dental bur. The improvement comprises the insertion of a means for reducing the air pressure to the power supply means in order to have the handpiece run at a pressure which is lower than the dentist's line pressure, without the necessity of changing the line pressure.
