摘要:

目的 对个别正常牙合者的牙弓与基骨弓匹配性进行研究,以期指导临床治疗。方法 选取30例个别正常牙合患者并拍摄锥形束CT,将牙弓与基骨弓标志点坐标进行数学处理,并通过统计学分析建立上下颌牙弓匹配的数学方程,以及牙弓与基骨弓的匹配数学方程。结果 上下颌牙弓在尖牙区及第二磨牙区的宽度、深度有很强的相关性(r尖牙深度=0.967,r尖牙宽度=0.949,r磨牙深度=0.948,r磨牙宽度=0.942),上下颌基骨弓在尖牙区的深度与宽度匹配关系较弱(r上颌尖牙深度=0.922,r上颌尖牙宽度=0.701,r下颌尖牙深度=0.971,r下颌尖牙宽度=0.629),在第二磨牙区的宽度与深度有很强的相关性(r上颌磨牙深度=0.973,r上颌磨牙宽度=0.988,r下颌磨牙深度=0.971,r下颌磨牙宽度=0.976)。结论 上下颌牙弓、基骨弓在尖牙区及第二磨牙区的宽度、深度存在匹配关系。

Abstract:

Objective To study the matching of dental and basal bone arch form in three-dimensional space in individual normal occlusion, to provide references for the clinical treatment. Methods A total of 30 subjects with individual normal occlusion were selected and taken CBCT, the dental arch and the basal bone arch mark point coordinates were processed by mathematical method in order to establish the matching mathematical equation of maxilla and mandibular, the matching mathematical equation of the dental arch and basal bone arch by statistical analysis. Results The width and depth of maxilla and mandibular dental arch were highly correlated in canine region and the second molar region. The width and depth of basal bone arch were moderate correlated in canine region,and strong correlated in the second molar region. Conclusion Maxilla and mandibular dental arch, the basal bone arch of individual normal occlusion were highly correlated in the width and depth of canine region and the second molar region. Personalized dental arch matching mathematical equation was established through the regression equation.
