Abstract: An ultrasonic dental tool for use with an ultrasonic transducer, comprises a substantially elongate tool defined by a shaft having a proximal end with a connector for attachment to an ultrasonic transducer, a distal end having a tip configured for performing a dental procedure, and a uniform gradual tapered portion intermediate the distal end and the proximal end is composed of a medical grade titanium alloy.

Abstract: An ultrasonic dental tip that is hardened by a novel process that includes roughing the tip and then applying a metal nitride coating, such as titanium nitride (Ti--N) or zirconium nitride (Zr--N). The roughing is preferably accomplished by sandblasting the tip with a microblaster. Optionally the tip may be heat treated after it has been roughened and prior to being coated in order to further increase its hardness.
