Comparison of the piezoelectric cutter with a conventional cutting technique in orthognathic surgery

Comparison of the piezoelectric cutter with a conventional cutting technique in orthognathic surgery: The use of a piezoelectric cutter has been reported to improve outcomes in orthognathic surgery, particularly with regards to neurosensory disturbance of the inferior alveolar nerve. The aims of this retrospective longitudinal cohort study were to compare outcomes regarding neurosensory disturbance, and operating time. During two 15-month periods a single surgeon treated 24 consecutive patients with a conventional cutting technique and a further 24 consecutive patients with a piezoelectric cutter.
