基于三维数字化模型评估恒牙早期安氏Ⅰ类与Ⅱ类错牙合患者的牙弓形态
Evaluation of arch morphology in patients with Class Ⅰ and Class Ⅱ malocclusion in the early permanent denti-tion based on three-dimensional digital model
摘要
Abstract
Objective:To evaluate the dental arch morphology of patients with Class Ⅰ and Class Ⅱ malocclusion in the early stage of permanent dentition by digital model,to compare the differences in dental arch width,palatal vault height and mandibular basal arch width between these two types of malocclusion.Methods:From June to December 2023,50 pa-tients with Class Ⅰ and 50 patients with Class Ⅱ were selected from the Stomatological Hospital of Xiamen Medical College.The width of the anterior,middle and posterior segments of the dental arch,the palatal vault height and the width of the man-dibular base arch were measured using a digital model.Results:The upper and lower dental arch widths were significantly re-duced in the Class Ⅱ patients compared with Class Ⅰ patients,and this difference was statistically significant(P<0.05).In ad-dition,the mandible basal bone widths of Class Ⅱ patients were smaller than that of Class Ⅰ patients,and the difference was statistically significant(P<0.05).However,the difference in the palate height between the two groups was not significant in statistics.Conclusion:Angle Class Ⅱ patients have narrower maxillary and mandibular dental arches and mandibular basal arch widths compared to Angle Class Ⅰ patients.This suggests that in the early treatment of permanent teeth in Angle Class Ⅱ patients,special attention should be paid to the coordination between the dental arch width and the basal arch width,as well as the matching of the maxillary and mandibular dental arch widths.关键词
