Adult patients' severe malocclusions, especially the skeletal ones, cannot be exclusively solved by the orthodontic treatment and therefore a combined orthodontic-surgical treatment is necessary. Today, numerous software allows to plane and to visualize the final treatment results simulating the best therapeutic option. This is a retrospective experimental study that aims to analyze the changes in the buccal cortical bone in patients undergoing orthodontics surgeries and to evaluate the correlation between the dental movement and the changes in the relative bone cortex. The study sample consists of 32 subjects. By applying the CBCT radiographic examinations, the measurements were made in well-defined points of reference. The 3D study of the dental changes of position and the cortical buccal bone related variation, suggests how the determined orthodontic movement of the dental element does not achieve an easily predictable bone variation. Therefore, it also suggests that there is no direct proportionality relationship between the extent of bone apposition/reabsorption and dental movement.
成人患者的严重错颌畸形，尤其是骨骼畸形，不能仅通过正畸治疗来解决，因此需要进行正畸-正颌联合治疗。如今，许多软件可以通过模拟最佳治疗方案来规划和可视化最终的治疗效果。这是一项回顾性的实验研究，旨在分析接受正畸手术的患者颊侧皮质骨的变化，并评估牙齿移动与相对骨皮质变化之间的相关性。研究样本包括 32 名受试者。通过应用 CBCT 射线照相检查，在明确的参考点进行了测量。对牙齿位置的三维研究和相关的颊侧皮质骨变化表明，确定的牙齿元素正畸移动并不能实现可预测的骨变化。因此，这也表明骨吸收/形成的程度与牙齿移动之间没有直接的比例关系。
