Inlfuence factor analysis of facial proifle and features of skeletal class III malocclusion before and after combined orthodontic and surgical treatments
摘要
Abstract
Objective To provide further and effective reference for the combined orthodontic and surgical treatments of patients with skeletal class III malocclusion.through studying the changes between the characteristics of soft and hard tissue proifle before and after combined orthodontic and surgical treatments.MethodsThe study included 73 skeletal class III malocclusion patients.Chose 21 indexes which pertaining to the characteristics of soft and hard tissue proifle from the imaging data before and after combined orthodontic and surgical treatments.then research the influencing factors through contrast analysis and correlation analysis.Results There was signiifcant differences between the before and after combined orthodontic and surgical treatments in the 17 of above mentioned indexes,except for ANS-Me/N-Me (%),L1-NB (mm),Y-axis angle(°) and MP-SN (°). High correlation was found in several hard tissue indexes and their corresponding soft tissue indexes, the correlation coefifcient of NP-FH(°) and Y-axis angle(°),SNA(°) and FH- N`Pg`(°) attain to 0.914,-0.883,-0.742 respectively.Conclusion According to skeletal class III malocclusion patients,osseous factor is the main inlfuencing factors on facial proifle,others are dental factor and soft tissue thickness.Cephalometric characteristics of these patients mainly reflected the lower one third of the face to the overgrown in the sagittal deformity, often accompanied by receding chin, while the vertical to the general has no obvious abnormalities. Through combined orthodontic and surgical treatments can improve the side appearance.关键词
