Abstract
- This study was intended to evaluate condyle position using simple ruler method in sagittal split ramus osteotomy for mandibular setback in 15 patients by paired t-test. We used oblique transcranial radiographs taken before operation and immediate after operation. And we concluded as follows; 1. The joint spaces changed under 0.2mm were 21.2%, 0.2mm to 1.0mm were 67.7%, above 1.0mm were 11.1%. 2. The mean changes of AJS, SJS, PJS were all increased and SJS was most changed of them, but there is no statistically significant change in SJS. 3. Comparing the preop. measurements with the postop. ones, there is no statistically significant changes in over all joint spaces (P> 0.05)
