postoperative pain, intraoperative bleeding
SUPERNUMERARY TEETH, INTRAOPERATIVE BLEEDING
Using piezosurgery to remove the inverted, horizontal, and root tip embedded supernumerary teeth, although the long operation time is its shortcoming, it can reduce the amount of intraoperative bleeding, postoperative pain, and facial swelling, improve the comfort of patients, and reduce the risk of surgery. Therefore, we recommend that the application of piezosurgery be considered first in this case. However, the application of piezosurgery combined with HSCAH is first considered in the extraction of oblique, orthodontic, middle and crown segments of embedded supernumerary teeth.
