A computerized tomographic study on the structure of the mandibular ramus

0.05).2. On horizontal section, The distance between the inferior alveolar canal and the lateral cortical plate of the mandibular ramus were 6.73+/-1.24mm minum, 7.70+/-1.44mm maximum.3. On coronal section, Outer mandibular angle were 4.84+/-2.37degrees right side, 4.93+/-2.12degrees left side.4. The design of the ideal true sagittal split ramus osteotomy is that posterior border of osteotomy must be limited vertically, at the right posterior point of lingula mandibularis and anterior border of osteotomy must be extended to mandibular body, anteroinferiorly.
