Abstract
To study the relationship between the depth of the curve of spee (COS) and different Angle classifications of malocclusion, overbite, overjet. The dental 3D models of 200 patients with malocclusion were selected as samples from Shenzhen Stomatology Hospital (Pingshan) of Southern Medical University from January 2021 to October 2022,Data are expressed as mean ± standard deviation (SD). SPSS 26.0 statistical software was used to conduct statistical analysis. The depths of the COS in the different categories of malocclusion, overbite, and overjet were compared by One-way analysis of variance (ANOVA) of the Duncan method. The correlation between the depth of the COS and dental diseases, including malocclusion, overbite, and overjet was analyzed by Pearson correlation analysis.Results. There was statistically significant difference between different types of Angle's classification ,overbite, overjet in the depth of COS.There was correlation between the depth of COS and overbite ,overjet of front teeth, overjet showed the highest correlation with the depth of COS.
