摘要/Abstract

摘要： 目的: 分析青少年安氏Ⅱ类亚类错患者平面倾斜度、磨牙倾斜度及磨牙高度的CBCT表现,为临床诊疗提供参考。方法: 选择2019年1月—2022年12月苏州口腔医院收治的青少年错患者80例,其中安氏Ⅱ类亚类错40例为试验组,安氏Ⅰ类错40例为对照组。通过CBCT测量、比较2组患者后平面、前平面、上颌平面角度以及上下磨牙近远中倾斜度、颊舌向倾斜度、磨牙高度的差异。采用SPSS 23.0 软件包对数据进行统计学分析。结果: 试验组中性侧与远中侧后平面、前平面、上颌平面角度,上磨牙高度、下磨牙高度比较,差异有统计学意义（P<0.05）;上磨牙近远中倾斜度、下磨牙近远中倾斜度、上磨牙颊舌向倾斜度、下磨牙颊舌向倾斜度比较,差异无统计学意义（P>0.05）。对照组安氏Ⅰ类错患者左右两侧后平面、前平面、上颌平面角度,上磨牙高度、下磨牙高度、上磨牙近远中倾斜度、下磨牙近远中倾斜度、上磨牙颊舌向倾斜度、下磨牙颊舌向倾斜度比较,差异无统计学意义（P>0.05）;试验组前平面、后平面、上颌平面角度与上颌磨牙近远中向倾斜度、颊舌向倾斜度均呈显著负相关（P<0.01）,与磨牙高度呈负相关（P<0.05）。结论: 安氏Ⅱ类亚类错患者可能在后平面、前平面、上颌平面角度,上、下磨牙高度与安氏Ⅰ类患者存在显著差异,临床正畸治疗中需对此类患者提高警惕,选择合适的治疗时机,制定合理的矫治方案。

Abstract: PURPOSE: To study the CBCT imaging features of occlusal plane inclination, molar inclination, and molar height in adolescent patients with Class Ⅱ subdivision malocclusion, in order to provide reference for clinical diagnosis and treatment. METHODS: A total of 80 adolescent patients with malocclusion admitted to Suzhou Stomatological Hospital from January 2019 to December 2022 were selected, including 40 cases of Class Ⅱ subdivision malocclusion as the experimental group and 40 cases of Class Ⅰ malocclusion as the control group. The angles of the anterior, posterior and maxillary occlusal planes, as well as the inclination of the upper and lower molars in the mesial and distal direction, the inclination of the buccal and lingual direction, and the height of the molars were analyzed based on CBCT data. SPSS 23.0 software package was used for data analysis. RESULTS: There were significant differences in the angles of the neutral and distal anterior, posterior and maxillary occlusal planes, as well as the height of the upper and lower molars between the experimental group of patients with Class Ⅱ subdivision malocclusion(P<0.05); There was no significant difference in the inclination of the upper and lower molars in the mesial and distal direction, as well as in the inclination of the buccal and lingual directions(P>0.05). There was no significant difference in the comparison of left and right measurements in the control group(P>0.05). The angles of the anterior, posterior and maxillary occlusal planes in the experimental group were significantly negatively correlated with the inclination of the maxillary molars in the mesiodistal and buccal lingual direction(P<0.01), and negatively correlated with the height of the molars(P<0.05). CONCLUSIONS: Patients with Class Ⅱ subdivision malocclusion may have differences in the angles of the posterior, anterior, and maxillary occlusal planes, as well as the height of the upper and lower molars, compared to Class Ⅰ malocclusion patients. In clinical orthodontic treatment, it is necessary to be vigilant for such patients, trying to choose appropriate treatment opportunities, and reasonable treatment plans to prevent malocclusion from developing towards a more severe direction.
