The hybrid MMF takes advantage of MMF using both arch bars and SASs for mandibular fractures. In addition, it overcomes many problems presented by previous MMF methods.

ObjectiveThe purpose of this study was to evaluate displacement of the mandibular condyle after orthognathic surgery using a condylar-repositioning device.MethodsThe patient group comprised 20 adults who underwent bimaxillary surgery between August 2008 and July 2011. The degree of condylar displacement was measured by pre- and postoperative tomographic analysis using centric relation bite and a wire during surgery. A survey assessing temporomandibular joint (TMJ) sound, pain, and locking was performed. The 20 tomographs and surveys were analyzed using the Wilcoxon signed-rank test and McNemar's test, respectively.ResultsNo significant changes were observed in the anterior, superior, or posterior joint space of the TMJ (p > 0.05). In addition, no significant change was observed in TMJ sound (p > 0.05). However, TMJ pain and locking both decreased significantly after surgery (p < 0.05).ConclusionsDue to its simplicity, this method may be feasible and useful for repositioning condyles.
