Abstract
Objective This study aims to investigate the correlation between the inclination of the occlusal plane of maxillary canines and first molars in adult patients with different sagittal skeletal patterns,as well as the differences in the direction of occlusal plane inclination and the sagittal relationship of molars between Angle's subclasses,which provides a reference for the clinical treatment of such patients.Methods A total of 180 adult patients with normal occlusion were selected,including 60 cases of Angle class Ⅰ,60 cases of Angle class Ⅱ division 1,and 60 cases of Angle class Ⅲ(with 30 cases of subclass and non-subclass for Angle class Ⅱ division 1 and Ⅲ).Three-dimensional reconstruction of cone beam computed tomography was performed using Mimics software.The vertical distances from the maxillary bilateral ca-nines and first molars to the Frankfort horizontal plane were measured,and the inclination of the occlusal plane was calcu-lated.The direction of the occlusal plane inclination and the sagittal relationship of the molars were recorded.SPSS 26.0 software was used to statistically analyze the correlation between the inclination of the occlusal plane and diffe-rent sagittal skeletal patterns.The correlation between the sagittal relationship of molars and the direction of occlusal plane inclination in Angle subclasses was also explored.Results A correlation existed between the inclination of the occlusal plane of canines and first molars and different sagittal skeletal groups(P<0.05).A correlation existed be-tween the inclination of the occlusal plane in Angle subclass groups and non-subclass groups(P<0.05).In the Angle sub-class group,a correlation existed between the bilateral molar relationships and the direction of occlusal plane inclination(P<0.05).Conclusion Certain differences are observed in the inclination of the occlusal plane in adult patients with dif-ferent sagittal skeletal patterns.The correction of the occlusal plane inclination should not be ignored in the clinical diag-nosis,analysis,and treatment of patients with Angle class Ⅱ and Angle class Ⅲ,as well as their subclass.关键词
