Method of using ultrasonic dental tool

A method for disintegrating the cement which adheres a cap to a tooth thereby loosening the cap for removable comprising the steps of:

• providing an adjustable clamp, wherein said clamp has two legs, one leg having an ultrasonic device mounted thereon adapted and constructed to lie in abutment of a lower portion of said cap on one side thereof, said other leg having a compliant means adapted and constructed to lie in abutment of a lower portion of said cap on the other side thereof,
• clamping said device on the lower portion of opposite sides of a cap mounted on a tooth whereby the ultrasonic device is substantially perpendicularly held against one side of said lower portion of said cap,
• maintaining in abutment said compliant means against the opposite side of a lower portion of said cap thereby inhibiting lateral movement of said cap,
• activating said ultrasonic device to impinge lateral strokes against the side of said cap against which the ultrasonic device abuts
• controlling the lateral strokes of the ultrasonic device whereby lateral motion imparted to the said side of said cap is less than 10 microns, whereby causing a disintegrating of the cement to occur at said side of said lower portion of said cap to which the ultrasonic device impinges,
• permitting the said disintegrating to extend around to the other side of the said cap while continuing the activation of the ultrasonic device until the said cap is completely loosened,
• thereafter removing said cap.
