fa Three-dimensional mandibular change after sagittal split ramus osteotomy with a semirigid sliding plate system for fixation of a mandibular setback surgery جراحی دهان، فک و صورت Oral and Maxillofacial Surgery پژوهشي Research <p> <strong>Objective</strong></p><p>  This study proposes a new plate system, a sliding plate, after sagittal split ramus osteotomy (SSRO). The sliding plate was designed to adjust the spatial relationship between the proximal and distal segments during the postoperative period. This plate was used for mandibular setback surgery to minimize forward early relapse. </p><p> <strong>Study Design</strong></p><p>  Twenty-six Korean subjects who had undergone mandibular setback surgery by SSRO were included in this study. Skeletal stability was evaluated with lateral cephalograms and 3-dimensional cone-beam computerized tomography. </p><p> <strong>Results</strong> </p><p> Forward mandibular movement during the postoperative period was ∼2 mm. The condyles rotated inward on the axial view after surgery. Postoperatively, the condyle rotated outward on the axial view, inward on the coronal view, and forward on the sagittal view by a statistically significant amount. </p><p> <strong>Conclusions</strong></p><p>  The fixation method with sliding plates after SSRO was stable and convenient for the operators during surgery and postoperative care. </p><hr><p></p><p> <strong>Source: </strong>Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology </p><p><a href="http://www.oooojournal.net/article/S2212-4403(12)00229-5/abstract" target="_blank"><font color="#0000ff"> Full Text</font></a></p> 0 0 http://idai.ir/browse.php?a_code=A-10-32-1515&slc_lang=fa&sid=1 Moon-Ho Ghang 10031947532846006931 10031947532846006931 No Department of Oral and Maxillofacial Surgery, School of Dentistry, Seoul National University, Seoul, Korea Hyung-him Min 10031947532846006932 10031947532846006932 No Department of Radiology, Brigham and Women's Hospital, Harvard Medical School, Boston, MA, USA John-Yung You 10031947532846006933 10031947532846006933 No Gnatho Orthognathic Surgery Clinic, Seoul, Korea Byoung-Ho Kim 10031947532846006934 10031947532846006934 No Smilefuture Orthodontic Clinic, Seoul, Korea Jae-Pyoung Choi 10031947532846006935 10031947532846006935 No Gnatho Orthognathic Surgery Clinic, Seoul, Korea Soo-Ho Kim 10031947532846006936 10031947532846006936 No Department of Oral and Maxillofacial Surgery, School of Dentistry, Seoul National University, Seoul, Korea Pill-Hoon Choung 10031947532846006937 10031947532846006937 Yes Department of Oral and Maxillofacial Surgery, School of Dentistry, Seoul National University, Seoul, Korea
