摘　　要：目的:探究安氏Ⅱ类不同年龄与Spee曲线深度的关系。方法:收集2015年7月~2019年7月来山西医科大学第一医院口腔正畸科就诊的88例安氏Ⅱ类患者牙齿石膏模型的三维数字模型及头颅侧位片。根据年龄将其分为两组:青年组(13周岁≤年龄≤18周岁)、成人组(年龄﹥18周岁)。根据GoGn-SN角将各组分成高角组、均角组、低角组。测量每组受试者的Spee曲线深度并进行统计学分析。结果:安氏Ⅱ类青年组与成人组Spee曲线深度存在统计学差异(P<0.05);安氏Ⅱ类不同垂直骨面型间Spee曲线深度存在统计学差异(P<0.05)。结论:随着年龄增长安氏Ⅱ类患者Spee曲线深度逐渐减少。Objective:To explore the depth of Spee curve between Angle II patients with different ages.Methods:The three-dimensional digital model and lateral slices of the skull of 88 Class II patients who were admitted to the Department of Orthodontics,the First Hospital of Shanxi Medical University from July 2015 to July 2019 were collected.They were divided into two groups according to age:youth group(13 years old≤age≤18 years old)and adult group(age>18 years old).The components were grouped into a high angle group,a mean angle group,and a low angle group according to the GoGn-SN angle.The Spee curve depth of each group was measured and statistical analysis was performed.Results:There was a statistically significant difference in the depth of Spee curve between the Young's class II and the adult group(P<0.05).There was a statistically significant difference in the depth of the Spee curve between the Class II and different vertical bone types(P<0.05).Conclusion:The Spee curve depth of Angle II patients gradually decreases with age.
