本研究的目的是利用锥形束计算机断层扫描（CBCT）确定具有不同垂直面部尺寸的受试者皮质骨厚度的差异。从114个治疗前CBCT扫描中，选择48个扫描纳入研究。利用cbct合成侧位脑电图根据受试者的垂直骨骼模式将其分为三组。在上颌和下颌骨的整个有牙区，测量了从牙槽嵴开始的两个垂直水平（4和7 mm）的皮质骨厚度（CBT）。与平均角度和低角度受试者相比，高角度受试者在某些部位的神经根间认知行为明显变窄，组间差异显著。根间皮质骨在高角度比平均角度或低角度的受试者更薄，在垂直高度的少数特定位置，通常插入微型种植体用于正畸固支。
The purpose of this study was to determine differences in cortical bone thickness among subjects with different vertical facial dimensions using cone beam computed tomography (CBCT). From 114 pre-treatment CBCT scans, 48 scans were selected to be included in the study. CBCT-synthesized lateral cephalograms were used to categorize subjects into three groups based on their vertical skeletal pattern. Cortical bone thickness (CBT) at two vertical levels (4 and 7 mm) from the alveolar crest were measured in the entire tooth-bearing region in the maxilla and mandible. Significant group differences were detected with high-angle subjects having significantly narrower inter-radicular CBT at some sites as compared to average- and low-angle subjects. Inter-radicular cortical bone is thinner in high-angle than in average- or low-angle subjects in few selected sites at the vertical height in which mini-implants are commonly inserted for orthodontic anchorage.
