安氏Ⅱ类患者牙颌面硬组织结构对Spee曲线深度的影响
Influence of dentofacial hard tissue structure on Spee curve depth in class Ⅱ division 1 mal-occlusion patients
摘要
Abstract
Aim To investigate the influence of dentofacial hard tissue structure on Spee curve depth in class Ⅱ division 1 malocclusion patients.Methods A total of 111 adult patients with class Ⅱ malocclusion were divided into three groups according to Spee curve depth,namely ≤2 mm group,2～3 mm group,and＞3 mm group,with 37 cases in each group.The parameters of dentofacial hard tissue structure among groups were compared,their correlation with Spee curve depth was analyzed,and the influen-cing factors of Spee curve depth was investigated.Results Compared with the＞3 mm group,the ODI and L6-MP angle were low-er,while the APDI and SNB angle were higher in the ≤2 mm group.Compared with the 2～3 mm and＞3 mm groups,the ANB an-gle,L7-MP angle and Spee curve depth were lower,while the L1-MP angle was higher in the ≤2 mm group.The Spee curve depth in the 2～3 mm group was lower than that in the＞3 mm group(P＜0.05).ODI,ANB angle,L6-MP angle,and L7-MP angle were positively correlated with Spee curve depth,while APDI,SNB angle,and L1-MP angle were negatively correlated with Spee curve depth(P＜0.05).ODI,ANB angle,L6-MP angle,L7-MP angle,APDI,SNB angle,and L1-MP angle were all influencing factors of Spee curve depth,among which SNB angle,followed by ANB angle(P＜0.05),were the most significant influencing factors.Conclusion The dentofacial hard tissue structure is closely related to the Spee curve depth in class Ⅱ division 1 malocclusion pa-tients,with SNB angle and ANB angle as significant influencing factors.关键词
