fa Criteria and limitations for selecting a sagittal split ramus osteotomy for patients with skeletal mandibular prognathism and open bite جراحی دهان، فک و صورت Oral and Maxillofacial Surgery پژوهشي Research <p> <strong>Purpose</strong></p><p>  The purpose of this study is to elucidate the criteria and limitations for selecting a sagittal split ramus osteotomy (SSRO) alone for patients with skeletal mandibular prognathism and open bite. </p><p> <strong>Study Design</strong></p><p>  The relationship between the mandibular relapse after 1 year and the extent of vertical movement following SSRO alone was investigated for patients with skeletal mandibular prognathism and open bite and the criteria were determined. </p><p> <strong>Results</strong></p><p> <strong> </strong>The limitation in SSRO alone was found to be 3-mm vertical movement at the gonion. There was a significant difference in the mandibular relapse between the patients with >3-mm change and <3-mm change.</p><p> <strong> Conclusions</strong></p><p>  For patients with skeletal mandibular prognathism and open bite, if the vertical movement at the gonion is <3 mm, SSRO alone could be an effective treatment. However, if the movement is >3 mm, SSRO alone should be avoided and bimaxillary osteotomies may be a preferable treatment. </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)00445-2/abstract" target="_blank"><font color="#0000ff">Full Text</font></a></p> 0 0 http://idai.ir/browse.php?a_code=A-10-32-1572&slc_lang=fa&sid=1 Izumi Yoshioka 10031947532846007268 10031947532846007268 No Division of Oral and Maxillofacial Surgery, Department of Sensory and Motor Organs, Faculty of Medicine, Miyazaki University, Miyazaki, Japan Tatsurou Tanaka 10031947532846007269 10031947532846007269 No Department of Oral Diagnostic Science, Kyushu Dental College, Kitakyushu, Japan Manabu Habu 10031947532846007270 10031947532846007270 No Department of Oral and Maxillofacial Surgery, Kyushu Dental College, Kitakyushu, Japan Masafumi Oda 10031947532846007271 10031947532846007271 No Department of Oral Diagnostic Science, Kyushu Dental College, Kitakyushu, Japan Masaaki Kodama 10031947532846007272 10031947532846007272 No Department of Oral and Maxillofacial Surgery, Kyushu Dental College, Kitakyushu, Japan Shinya Kokuryo 10031947532846007273 10031947532846007273 No Department of Oral and Maxillofacial Surgery, Kyushu Dental College, Kitakyushu, Japan Shinji Kito 10031947532846007274 10031947532846007274 No Department of Oral Diagnostic Science, Kyushu Dental College, Kitakyushu, Japan Nao Wakasugi-Sato 10031947532846007275 10031947532846007275 No Department of Oral Diagnostic Science, Kyushu Dental College, Kitakyushu, Japan Shinobu Matsumoto-Takeda 10031947532846007276 10031947532846007276 No Department of Oral Diagnostic Science, Kyushu Dental College, Kitakyushu, Japan Yasuhiro Morimoto 10031947532846007277 10031947532846007277 Yes Department of Oral Diagnostic Science, Kyushu Dental College, Kitakyushu, Japan
