摘　　要：目的通过对安氏Ⅱ类与Ⅲ类患者数字化牙颌模型进行测量分析,为临床矫治计划的设计提供依据。方法收集30例安氏Ⅱ类与30例安氏Ⅲ类患者,扫描其石膏模型生成数字化模型,使用三维测量软件对数字化模型的牙弓宽度及基骨弓宽度进行测量,采用SPSS 25.0软件对测量结果进行统计学分析。结果安氏Ⅱ类错[牙合]畸形各测量牙位数据比较,差别有统计学意义(P<0.05);安氏Ⅲ类错[牙合]畸形患者在上颌第二前磨牙区牙弓与基骨弓宽度比较,差别无统计学意义(P>0.05),其牙弓宽度为(52.94±1.85)mm,基骨弓宽度为(52.31±3.03)mm,其他牙位测量数据比较,差别有统计学意义(P<0.05)。安氏Ⅱ类与Ⅲ类错[牙合]畸形牙弓宽度比较,差别有统计学意义(P<0.05);安氏Ⅱ类与Ⅲ类错[牙合]畸形基骨弓宽度对比在上颌第二前磨牙区、上颌第二磨牙区、下颌第二前磨牙区差别无统计学意义(P>0.05),其他牙位比较差别有统计学意义(P<0.05)。结论安氏Ⅱ类上颌尖牙区宽度较安氏Ⅲ类患者大,其他部位牙弓宽度较Ⅲ类患者小;安氏Ⅱ类错[牙合]畸形患者上颌基骨弓宽度大于安氏Ⅲ类患者,而下颌基骨弓宽度小于安氏Ⅲ类患者。Objective To analyze and compare ClassⅡ dental arch and basal bone characteristics of patients with ClassⅢ through digital dental model,and to provide the basis for the design of clinical treatment plan.Methods There were 30 patients with ClassⅡand 30 patients with ClassⅢ who were collected.The gypsum model was scanned by digital scanning to generate a digital model.The digital model was measured using 3D measurement software.The measurement results were statistically analyzed using SPSS 25.0 software.Result There were statistically significant differences in the ClassⅡ malocclusion dental position measurement data(P<0.05)There were no significant differences in the width of the dental arch and the basal bone in the maxillary second premolar area of the ClassⅢmalocclusion(P>0.05),the width of the dental arch was(52.94±1.85)mm and the width of the basal bone arch was(52.31±3.03)mm,comparison of other dental measurement data were statistically significant(P<0.05).There was a statistically significant difference in the width of dental arch between ClassⅡand ClassⅢ malocclusion(P<0.05).There was no significant difference in the maxillary molar area,the second molar area,and the mandibular second premolar area in the width of the base bone arch between the ClassⅡand ClassⅢ malocclusion;the data of other dental measurements were statistically significant(P<0.05).Conclusion The width of the ClassⅡ maxillary canine is larger than that of the ClassⅢ patients,and the width of the other parts is smaller than that of the ClassⅢ patients.The width of the maxillary basal arch of the ClassⅡ malocclusion is greater than that of the ClassⅢ patients,while the mandibular basal arch width is smaller than ClassⅢ patients.
