Purpose : This study aimed to determine the relationship between mandibular submarginal cortical bone morphology and vertical maxillofacial morphology in patients with skeletal mandibular prognathism using the mandibular cortical index (MCI) and digital imaging.
Materials and methods : The subjects consisted of 142 patients diagnosed with skeletal mandibular prognathism. FMA of the lateral cephalogram analysis was used to classify the patients into long, middle, and short face type. MCI Ⅰ was classified as Group 1, and MCI types Ⅱ and Ⅲ were classified as Group 2 using digital panoramic radiographs.
Results : Group 2 with low bone mineral density accounted for 75.0％ of the long face, 56.1％ of the medium face, and 44.8％ of the short face type, showing a significant difference between the long and short face types.
Conclusion : These results suggest that the long face type has low mandibular bone density.
