A tooth extraction assisting device includes an ultrasonic machine, an ultrasonic hand piece, and 5 different insert tips that are hook-on to the hand piece. The ultrasonic machine outputs a signal with high frequency oscillation. This high frequency oscillation signal received by the ultrasonic hand piece generates a high frequency vibration of the insert tip. A set of 5 different configuration insert tips was designed for a precision surgical cut at the coronal portion of the periodontal ligament around tooth to be extracted. This device also provides a better visibility at the surgical area with the cavitation effect. With the help of the tooth extraction assisting device dental clinician is able to perform tooth extraction with less chair-time without damaging to the buccal alveolar process which increases the chance of immediate implant placement at the same appointment.
