Abstract
A piezoelectric device comprising:
- (a) a handpiece for holding by a user;(b) a cutting insert for said handpiece;(c) an ultrasound transducer disposed within the handpiece, the ultrasound transducer capable of providing first and second ultrasound frequency vibrations to the cutting insert in response to an electrical signal; and(d) a switch allowing the user to control the electrical signal and thereby provide either said first or second ultrasound frequency vibrations to the cutting insert.The device is useful in a method of placing an implant into an implant site comprising cutting overlying gingival tissue at a first ultrasound frequency capable of cutting soft tissue, then switching to a second ultrasound frequency capable of cutting the underlying jawbone.
