Identification Of Stiffness Variations In Supporting Substances Of A Human Canine Tooth With A Bracket-Beam-Piezoelectric Sensor And Its Electromechanical Impedance, Hector A. Tinoco
Future Dental Journal
In this paper, an experimental method is described to identify the stiffness variations produced by drillings done in different supporting substances of a human canine tooth. To measure the supporting substances parameters through of a canine, a sensor-actuator systemwas developed. The sensor-actuator device was composed of a stainless steel bracket bonded to a steel wire attached to two piezoelectric transducers, with a concentrated mass attached to the end of the wire. To excite the device, high frequency voltage (between 5 and 10 KHz) was applied through the piezo-transducers, which affects the tooth by means of the vibration of the wire. …
