摘要: Abstract This study was performed to assess the effect of correcting skeletal class II malocclusion based on application computer-assisted design and manufacturing (CAD/CAM) cutting drilling guides accompanied with pre-bent titanium plates. Fifty patients were recruited into this prospective randomized controlled clinical trial assigned two groups. Patients underwent bilateral sagittal split ramus osteotomy directed by CAD/CAM plates (group A) or splints B). Postoperative assessments performed. Differences between virtually simulated postoperative models measured. in both groups had a satisfactory occlusion appearance. More accurate repositioning proximal segment found group A than B when comparing linear angular differences reference planes; however, no significant difference revealed for distal segment. In conclusion, can provide considerable surgical accuracy positional control segments correction deformities.
