It is aimed to examine the tooth sizes of digital models of patients with different malocclusions with the help of three-dimensional measurement software.
Digital models of 252 patients aged between 13 and 25 years of age were included. According to the Angle classification, three different malocclusion groups were allocated such that there were 84 patients in each group, plaster models of patients scanned with the three-dimensional model browser 3Shape R700 3D Scanner (3Shape A/S Copenhagen, Denmark) and transferred to the digital format. 3Shape Ortho Analyzer (3Shape A/S Copenhagen, Denmark) software was used for making the necessary tooth size measurements.
When the measurements were evaluated, it was determined that significant changes occurred between tooth sizes of individuals with different malocclusions. Generally, higher values were observed in mesiodistal and buccolingual tooth dimensions of class II individuals compared to other groups. There was no difference between the groups in the anterior ratio values, but when the overall ratio values were evaluated among the groups, a statistically significant difference was determined. Class II malocclusion group was found to have a significantly lower overall ratio of occurrence.
Individuals with different malocclusions differ in tooth size.
借助三维测量软件，检查不同错牙合患者数字模型的牙齿大小。
纳入年龄在 13 至 25 岁之间的 252 名患者的数字模型。根据 Angle 分类，将三个不同的错牙合组分配给每个组有 84 名患者，使用 3Shape R700 3D Scanner（3Shape A/S Copenhagen，丹麦）扫描患者的石膏模型并转换为数字格式。使用 3Shape Ortho Analyzer（3Shape A/S Copenhagen，丹麦）软件进行必要的牙齿尺寸测量。
在评估测量结果时，确定不同错牙合患者的牙齿尺寸存在显著变化。一般来说，与其他组相比，类 II 个体的近远中向和颊舌向牙齿尺寸更高。各组的前牙比例值无差异，但在组间评估总体比例值时，确定存在统计学差异。类 II 错牙合组的总体发生比例明显较低。
不同错牙合患者的牙齿大小存在差异。
