Criteria and limitations for selecting a sagittal split ramus osteotomy for patients with skeletal mandibular prognathism and open bite

Purpose 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. Study Design The relationship between the mandibular relapse after 1 year and the extent of vert...

Description
Summary:Purpose 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. Study Design 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. Results 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
