应用CEREC3 CAD/CAM对上颌隐裂磨牙牙尖斜度的研究
A measurement of cracked teeth on the maxillary first molar cusp inclination by using CEREC3 CAD / CAM.
摘要
Abstract
Objective: To study the anatnmical etiology of the cracked molars by measuring cuspal inclination of the cracked molars. Method: Measuring cuspal height, cuspal oblique ridge length and the distance between the cusp of cracked teeth group and control group by using CEREC3 CAD / CAM and calculating the inclination of the cusp, the mesial buccal-lingnal inclined angle and the distal buccal-lingual inclined angle. Result: Significant differences are found between cracked teeth group and control group in the mesial buccal-lingnal inclined angle and the distal buccal-lingnal inclined angle (P ＜0.05). Conclusion: It suggests that the factors of dental anatomy are closely related with the incidence of crocked teeth. The bigger the inclination and the smaller cuspal inclined angle, the greater possibility occurs cracked teeth.关键词
