结构化摘要目的 目的是利用混合效应分析，根据 9 年纯纵向数据的侧位头颅照片，评估与骨骼开合和深覆合受试者生长相关的骨骼因素。背景和样本人群从总共 223 名受试者中，将 51 名 14 岁时前面部高度与前面部总高度 (LAFH/TAFH) 比率值极低的儿童分配到骨骼性开咬合组或骨骼性深咬合组。材料与方法 测量并分析腭平面角（PPA）、下颌平面角（MPA）、角角（GA）、腭下颌平面角（PMA）、上角角（UGA）、下角角（LGA）、咬合平面角（OPA）和覆牙合深度指示器（ODI）。混合效应回归模型分析用于解释具有随机效应的数据。结果 MPA、GA、PMA、ODI 和 LGA 的形态差异从一开始就很明显，并且随着年龄的增长变得更加明显。所有变量的初始值均具有统计显着性。 GA、OPA、ODI 和 UGA 随年龄增长的年增长率具有统计学意义。 MPA、GA、PMA和UGA逐年增加的形态差异也具有统计学意义。结论 形态上不同的生长模式主要是由于前面部高度尺寸较低造成的。个体差异的程度要求在临床情况下做出明智的决策。
Structured Abstract Objective The purpose was to evaluate skeletal factors related to the growth of subjects with skeletal open and deep bites based on lateral cephalographs from 9 years of pure longitudinal data using mixed effect analysis. Setting and Sample Population Fifty-one children with extreme lower anterior facial height to total anterior facial height (LAFH/TAFH) ratio values at the age of 14 were assigned to either skeletal open bite or skeletal deep bite groups from a total of 223 subjects. Material & Methods The palatal plane angle (PPA), mandibular plane angle (MPA), gonial angle (GA), palatomandibular plane angle (PMA), upper gonial angle (UGA), lower gonial angle (LGA), occlusal plane angle (OPA) and overbite depth indicator (ODI) were measured and analysed. Mixed-effects regression model analysis was used for the interpretation of data with random effects. Results Morphological differences were evident from the beginning and became more pronounced with age in MPA, GA, PMA, ODI and LGA. The initial values of all variables were statistically significant. Annual increases with age were statistically significant in GA, OPA, ODI and UGA. The morphological differences in the annual increases in MPA, GA, PMA and UGA were also statistically significant. Conclusions Morphologically different growth patterns were mainly contributed by lower anterior facial height dimensions. The extent of individual variations mandates judicious decision-making in clinical situations.
