The aim of the study was to compare in a randomized controlled clinical trial use piezoelectric osteotomy as an alternative conventional approach terms surgery time, intraoperative blood loss, cut quality, nerve injury, and costs. One hundred ten patients who had orthognathic procedures with bimaxillary were divided into 2 groups: group A treated piezosurgery device, B, reciprocating saw bur. piezosurgical bone permitted individualized designs. surgical time reduced, mean for mandibular (1 side) between 3 minutes 31 seconds 5 seconds, whereas 7 23 10 22 seconds. Le Fort I 17 55 8 38 15 11 B. All low loss (<300 mL) versus B medium high (medium loss: 400 mL, >500 mL). Inferior alveolar sensation retained 98.2% 92.7% at 6 months postoperative testing. Piezoelectric reduced inferior injury osteotomy. Absence macrovibrations makes instrument more manageable easy allows greater control higher safety cutting difficult anatomical regions.
