This paper from Seattle in the United States looked at 20 patients with a mean age of 19.9 +/- 3.2 years with a fairly standard surgical movement. They found that functional sensory recovery of the inferior alveolar nerve resulted in a higher neurosensory score at the time of assessment and a shorter time to complete neurosensory recovery using a piezoelectric in comparison to a reciprocating saw. Whilst there are many shortcomings within this brief paper including genioplasty in addition to sagittal split osteotomies, it being completed with split mouth and not randomised and small size, it does add to the increasing evidence of the benefits of piezoelectric surgery.

Does the use of a piezoelectric saw improve neurosensory recovery following sagittal split osteotomy.
