Abstract
This study aimed to compare the mandible inferior cortical bone thickness before and after orthognathic surgery on panoramic radiographs. Among 1092 orthognathic surgery patients, 37(12male, 25 female, average age 23.8 yrs± 4.4) were selected who underwent mandible inferior cortex contouring. The total mandible sides which underwent inferior cortex contouring were 62. The mandible inferior cortical bone thickness was measured below the mesial root of the first molar tooth. The mandible inferior cortical bone thickness was 3.49mm± 0.6mm before orthognathis surgery and 1.92 mm± 0.88 mm after surgery, with statistically significant difference between the two(p<.05). The mean contouring amount was 1.57 mm± 0.8 mm. Mandible inferior cortex contouring are often included in orthognathic surgery.
