摘要： 目的 基于CBCT分析青少年骨性Ⅰ类与骨性Ⅱ类均角患者上颌前后平面倾斜度、下颌平面角、下颌角（总角、上角、下角）及面下部高度的差异及相关性,为两类患者的正畸诊疗提供参考。方法 选择2023年1月—2023年12月于苏州口腔医院正畸一科治疗的青少年骨性Ⅰ类与Ⅱ类均角患者各37例。采用CBCT扫描及Dolphin Imaging 11.95软件重建头颅侧位片,测量上颌前平面、后平面倾斜度,以及下颌总角、下颌上角、下颌下角、面下部高度、下颌平面角（MP-FH）、SNA角、SNB角、ANB角。结果 骨性Ⅱ类组的上颌前平面、后平面倾斜度显著大于骨性Ⅰ类组（P<0.01）,骨性Ⅱ类组的下颌总角、下颌下角、面下部高度、下颌平面角均显著大于骨性Ⅰ类组（P<0.05）;骨性Ⅱ类组SNA角更大（P<0.05）,SNB角更小（P<0.01）。两组患者上颌前平面、后平面倾斜度均与面下部高度、下颌平面角呈正相关,且相关性均有统计学意义（P<0.05）;与SNA角、SNB角呈负相关,与ANB角呈正相关,其中骨性Ⅱ类组的相关性有统计学意义(P<0.05)。结论 上颌前、后平面倾斜度与矢状骨面型及垂直骨面型有关;与下颌平面角、面下部高度及ANB角呈正相关,与SNA角及SNB角呈负相关。

Abstract: PURPOSE: To analyze the differences and correlations in the inclination of the maxillary anterior and posterior occlusal planes, mandibular plane angle, mandibular angles(total angle, upper angle, lower angle), and lower facial height between adolescent patients with skeletal Class Ⅰ and skeletal Class Ⅱ normodivergent facial patterns based on CBCT, so as to provide a reference for orthodontic diagnosis and treatment of these two groups of patients. METHODS: A total of 37 adolescent patients with skeletal Class Ⅰ normodivergent facial pattern and 37 with skeletal Class Ⅱ normodivergent facial pattern who received orthodontic treatment at Suzhou Stomatological Hospital from January 2023 to December 2023 were selected. CBCT scanning and Dolphin Imaging 11.95 software were used to reconstruct lateral cephalograms. The inclinations of the maxillary anterior occlusal plane and posterior occlusal plane, as well as the total mandibular angle, upper mandibular angle, lower mandibular angle, lower facial height, mandibular plane angle(MP-FH), SNA angle, SNB angle, and ANB angle were measured. RESULTS: The inclinations of the maxillary anterior and posterior occlusal planes in the skeletal Class Ⅱ group were significantly greater than those in the skeletal Class Ⅰ group(P<0.01); the total mandibular angle, lower mandibular angle, lower facial height, and mandibular plane angle in the skeletal Class Ⅱ group were significantly larger than those in the skeletal Class Ⅰ group(P<0.05); the SNA angle in the skeletal Class Ⅱ group was larger (P<0.05), while the SNB angle was smaller (P<0.01). In both groups, the inclinations of the maxillary anterior and posterior occlusal planes were positively correlated with the lower facial height and mandibular plane angle, with statistically significant correlations(P<0.05); they were negatively correlated with the SNA angle and SNB angle, and positively correlated with the ANB angle, among which the correlations in the skeletal Class Ⅱ group were statistically significant (P<0.05). CONCLUSIONS: The inclinations of the maxillary anterior and posterior occlusal planes are related to the sagittal and vertical skeletal facial patterns; they are positively correlated with the mandibular plane angle, lower facial height, and ANB angle, which negatively correlates with the SNA angle and SNB angle.
