ABSTRACT:
The present invention is directed toward a handheld dental instrument which automatically regulates the pressure at which the working end of the instrument engages a person's teeth or gums. The instrument includes a probe that is spring biased into a set position. The bias of the probe is predetermined, and is designed to yield to a preset minimum force. The deformation of the instrument's spring bias keeps the force of the instrument consistent against any object. This consistent pressure assures that the instrument will work in the same manner, and give the same results, time after time. Additionally, the consistency of the instrument will result in more accurate results and increase in the dentist's confidence while using the instrument.
