A study was conducted to evaluate the relationship between morphological characteristics of vertical sections of the mandibular body and dentopfacial morphology. Cortical bone thickness, tooth inclination and bone inclination of the mandible were investigated. Among skeletal components, ANSMe distance was associated with the buccal cortical bone thickness of the P2 (second premolar) section. Gonial angle, SN to mandibular angle, and palatal to mandibular angle were negatively correlated with the buccal cortical bone thickness of P2 and M1 (first molar) sections. SNA and SNB which indicated the protrusion of the upper and lower jaws were positively correlated with the buccal cortical bone thickness of the M1 section. Among denture components, lower and upper incisor positions showed a significant negative correlation with the buccal cortical bone thickness of the P2 section. The interincisal angle was associated with the basal cortical bone thickness of the M2 (second molar) section. In summary, there were significant and complex relationships between the structures of the mandibular body and maxillofacial morphology. Facial types which relate to masticatory function are associated with the cortical bone thickness of the mandibular body.
进行了一项研究以评估下颌体垂直截面的形态特征与牙颌面形态之间的关系。研究了下颌骨的皮质骨厚度、牙齿倾斜度和骨倾斜度。在骨骼组成部分中，ANSMe距离与P2（第二前磨牙）截面的颊侧皮质骨厚度相关。下颌角、SN至下颌角以及腭至下颌角与P2和M1（第一磨牙）截面的颊侧皮质骨厚度呈负相关。表示上下颌前突的SNA和SNB与M1截面的颊侧皮质骨厚度呈正相关。在义齿组成部分中，上下切牙位置与P2截面的颊侧皮质骨厚度呈显著负相关。切牙间角与M2（第二磨牙）截面的基底皮质骨厚度相关。总之，下颌体结构与颌面形态之间存在显著且复杂的关系。与咀嚼功能相关的面部类型与下颌体的皮质骨厚度有关。
