“…The incidence of severe relapse is 3% and of mild relapse 8% . Possible factors that can lead to relapse are : the amount of mandibular advancement or setback; advancements more than 7 mm increase the risk; type of fixation; proximal segment control, including condylar positioning and prevention of proximal segment rotation; prevention of counterclockwise rotation of the distal segment in cases with a high mandibular plane angle; stretching of the perimandibular tissues, including skin, connective tissues, muscles and periosteum.…”

“…To summarize these 6 studies, the outcomes of 141 patients with CPDs were compared with those of 112 patients treated using conventional manual repositioning. Three studies supported the use of CPDs, 1 study supported the use of CPDs only in patients with temporomandibular disorders (TMDs), and 2 studies did not support the use of CPDs because they failed to improve skeletal stability or TMJ function, irrespective of the skeletal deformities treated [ 4 8 9 10 11 12 13 ].…”

BackgroundNumerous condylar repositioning methods have been reported. However, most of them are 2-dimensional or are complex procedures that require a longer operation time and a highly trained surgeon. This study aims to introduce a new technique using a condylar repositioning plate and a centric relation splint to achieve a centric relationship.MethodsWe evaluated 387 patients who had undergone surgery for skeletal jaw deformities. During the operation, a centric relation splint, intermediate splint, final centric occlusion splint, and condylar repositioning plate along with an L-type mini-plate for LeFort I osteotomy or a bicortical screw for bilateral sagittal split ramus osteotomy were utilized for rigid fixation. The evaluation included: a physical examination to detect preoperative and postoperative temporomandibular joint dysfunction, 3-dimensional computed tomography and oblique transcranial temporomandibular joint radiography to measure 3-dimensional condylar head movement, and posteroanterior and lateral cephalometric radiography to measure the preoperative and postoperative movement of the bony segment and relapse rate.ResultsA 0.3% relapse rate was observed in the coronal plane, and a 2.8% relapse rate in the sagittal plane, which is indistinguishable from the dental relapse rate in orthodontic treatment. The condylar repositioning plate could not fully prevent movement of the condylar head, but the relapse rate was minimal, implying that the movement of the condylar head was within tolerable limits.ConclusionsOur condylar repositioning method using a centric relation splint and mini-plate in orthognathic surgery was found to be simple and effective for patients suffering from skeletal jaw deformities.

“…A CPD is a valuable tool in the transition from nonrigid to rigid fixation, but these devices are cumbersome, and there is no scientific evidence to support their routine use in orthognathic surgery. Gerressen et al39 and Costa et al38 reported that a manual positioning technique enabled equally stable results in orthognathic surgery. They suggested that manual repositioning of the proximal segment continues to be the method of choice because it is easier and less expensive for intraoperatively identifying a malpositioned condyle.…”

Condylar repositioning using centric relation bite in bimaxillary surgery

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.
