研究目的: |
选取2019年1月至2024年3月于哈尔滨医科大学就诊骨性I类面部对称、骨性III类面部对称及骨性III类偏颌患者,利用CBCT评估骨性三类伴偏颌畸形患者、骨性III类面部对称患者上下颌后牙牙齿近远中、颊舌向倾斜角度及牙槽骨厚度,并与骨性I类面部对称患者对比。 |

Objectives of Study: |
Patients with skeletal class I ,asymmetrical skeletal Class III malocclusion and symmetrical skeletal Class III malocclusion were selected from Harbin Medical University from January 2019 to March 2024.The purposes of this retrospective study was using cone-beam computed tomography to investigate the dental compensation and alveolar bone thickness of posterior teeth in patients with asymmetrical skeletal Class III malocclusion and compared with Class III patients without mandibular deformity and skeletal class I patients. |
