ABSTRACT:
Improved means for directing an atomized water spray at the tip of a bur in a dental handpiece irrespective of the length of the bur. The means comprises a water carrying tube terminating at a free end adjacent to the bur and directed at the bur at a first predetermined acute angle with respect to the longitudinal axis of the bur, a first air carrying tube disposed on one side of the water tube and having a free end terminating adjacent the free end of the water tube and a second predetermined acute angle to the longitudinal axis of the bur, the second angle being greater than the first angle, and a second air carrying tube disposed on the outer side of the water tube and having a free end terminating adjacent the free end of the water tube and at a third predetermined acute angle with respect to the longitudinal axis of the bur, the third angle being smaller than the first angle. Metering means are provided for varying the flow through the air tubes to effect the control of the direction of the atomized spray.
In accordance one aspect of the invention, the free ends of the air tubes also extend in a first plane directed laterally to one side of the bur while the water tube is directed laterally to the other side of the bur to thereby compensate for any lateral deflection of the atomized spray resulting from windage caused by the rotating bur.
