Comparing border saw and reciprocating saw for lower jaw osteotomy
Official title: Evaluate How Use of an Inferior Border Saw While Making the Inferior Border Osteotomy During Sagittal Ramus Osteotomy Using the Low and Short Medial Osteotomy Modification Technique Affects the Lingual Fracture Pattern of the Mandible
Run by University of Alabama at Birmingham · NCT07104656 · Data updated 2026-11-12
This will see if using a border saw versus a reciprocating saw when making the lower jaw cut changes the pattern of inner bone breaks in people having mandibular surgery.

Is this trial a fit for you?
✓Likely a good fit
Patients scheduled for mandibular osteotomy who can undergo bilateral/split-mouth treatment and do not have severe syndromic dentofacial deformities are ideal candidates.
✕Probably not a fit
Patients with severe syndromic dentofacial deformities or those not undergoing mandible osteotomy would not be expected to benefit from this comparison.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This split-mouth interventional study enrolls patients undergoing mandibular osteotomy and applies a different cutting tool to each side: an inferior border saw on one side and a reciprocating saw on the other. Surgeons will document the medial cortex fracture pattern and any bony overlap that occurs after the inferior border osteotomy. The primary focus is whether use of the inferior border saw is associated with a specific medial cortex fracture pattern compared with the reciprocating saw. Procedures and follow-up are performed at the University of Alabama at Birmingham and exclude patients with severe syndromic dentofacial deformities.
Why it matters
Potential benefit: If successful, the results could reduce the rate of medial cortex fractures and improve healing and outcomes after lower jaw osteotomy.
How similar studies have gone: Direct split-mouth comparisons of these two specific saw techniques are limited, so this approach is relatively novel though instrument comparisons have appeared in surgical literature.
