“…[4][5][6] For these reasons, several positioning devices have been proposed and applied, but generally do not provide better long-term outcomes in either mandibular advancement or setback surgery. 7 These condylar repositioning devices seem to place the distal segment into the maxilla-mandibular fixation position, and the positioning plate is replaced, theoretically repositioning the condyle in all three dimensions.…”

Purpose. The purpose of this study was to evaluate bone formation between the proximal and distal segments after a sagittal split ramus osteotomy (SSRO) with bent plate fixation.Subjects and Methods. The subjects were 23 patients (46 sides) who underwent bilateral SSRO setback surgery. They were divided into titanium and absorbable plate groups. A 3-7 mm gap was made between the proximal and distal segments and a bent plate was fixed with 4 screws in each side of the mandible. The square of ramus (RmS), the antero-posterior length (RmA-RmP), and the medio-lateral width (RmM-RmL) of the ramus at the horizontal plane under the mandibular foramen were assessed preoperatively, immediately after surgery, and 1 year postoperatively by computed tomography (CT).Results. There were no significant differences between the titanium and absorbable plate groups over time. RmS after 1 year was larger than pre-operatively in both groups (P<0.0001). RmA-RmP significantly increased immediately after surgery and significantly decreased after 1 year in both groups (P<0.0001). RmA-RmP after 1 year was significantly larger than the preoperative value in both groups (P<0.0001). RmM-RmL showed a similar tendency to the antero-posterior length, but was not significant. Conclusion.The gap between the proximal and distal segments can fill with new bone after SSRO with both titanium and absorbable plates, even with few bony contacts between segments.

“…[4][5][6] For these reasons, several positioning devices have been proposed and applied, but generally do not provide better long-term outcomes in either mandibular advancement or setback surgery. 7 We previously used bent titanium plates to secure fragments in 20 patients without a positioning device. The angle of the bent plates was adjusted to avoid displacement of the condyle after osteotomy using the preoperative position of the condyle on submental-vertical (S-V) cephalograms.…”

Results. There was no significant difference in reduction in mandibular length between SSRO alone and SSRO with Le Fort I on the axial view of a 3D CT. There were no significant differences between pre-and postoperative horizontal changes in the condylar long axis or in the antero-posterior and medio-lateral displacement of the condylar head, although the length of the proximal segment in SSRO with Le Fort I osteotomy was significantly shorter than in SSRO alone (P<0.05). Conclusion.These results suggest that the use of a bent plate for SSRO does not change preoperative angle or position significantly in setback surgery, regardless of the addition of Le Fort I osteotomy.
