ABSTRACT:
An air driven dental handpiece having an air turbine at one end thereof. Collet means for securing a dental bur therein are positioned within the air turbine. The air turbine is mounted in ball bearings, which are in turn resiliently mounted within the turbine housing. The handpiece handle is hollow and includes air and water tubes therein. The air and water are mixed within the handpiece at the point of expulsion from the handpiece, thereby creating a coolant mist or fog on the dental bur and the tooth being drilled.
