A new condyle repositionable plate for sagittal split ramus osteotomy.
In sagittal split ramus osteotomy (SSRO) surgery, variable methods are used to maintain the proximal segment in the anatomic position during fixation to minimize early built-in relapse. However, there is still a chance of condyle malposition.In this study, a new titanium plate, which has a sliding oval hole in its distal part, was used to enable postoperative mobility of the proximal segment. This plate makes it possible to reposition the condyle during the postoperative intermaxillary fixation period.These plates were used successfully in 23 patients who received SSRO setback surgery. All of the patients were followed up without any complications, including early relapse or temporomandibular joint problems.The authors used a new plate that enables sliding of the proximal segment after SSRO, which can minimize early relapse without any postoperative complications.
