摘要:

目的 对儿童和成人深覆牙合患者的颅颌面形态进行横断面研究,分析其生长发育中颅颌形态变化的趋势,探讨成人深覆牙合患者的颅颌面形态特征。方法 随机抽取Ⅲ度儿童深覆牙合患者159例(平均年龄12.47岁),成人深覆牙合患者81例(平均年龄21.76岁),个别正常对照组51例(平均年龄18.41岁)。采用Winceph 7.0软件对3组X线头影测量项目进行测量,采用SPSS 12.0软件进行统计学分析。结果 儿童深覆牙合患者在上前面高、下前面高、上颌第一磨牙相对于上颌前部的位置、上颌骨长度、上下颌骨-平面距、上颌磨牙-腭平面距、下颌切牙-下颌平面距、上下齿槽座点平面-下颌平面角、下颌角、下颌切牙距、覆盖、下颌平面-前颅底平面角、下颌磨牙-下颌平面距、后面高、上颌切牙距、下颌体长度、下颌升支高度、平面-前颅底平面角、上颌中切牙-前颅底平面角与成人深覆牙合患者间差异有统计学意义。成人深覆牙合患者在下颌-前颅底平面角、上下颌骨-前颅底平面角、颌凸角、上下颌骨矢状向不调指数、上下颌骨垂直向不调指数、上下颌骨-平面距、上下齿槽座点平面-下颌平面角、下颌角、覆盖、下颌平面-前颅底平面角、上颌后部位置、下颌磨牙-下颌平面距、上颌中切牙-前颅底平面角、下颌体长度、下颌升支高度、后颅底长度、平面-前颅底平面角、后面高与正常个体间差异有统计学意义。结论 深覆牙合患者随着年龄的增长,颅、颌、、面部仍表现有一定的生长潜力,但是患者颌骨矢状关系并无改善。成人深覆牙合患者颌面部特征表现为垂直向、矢状向关系显著不调。

Abstract:

Objective To investigate the changes in the craniofacial morphology of deepbite from childhood to adulthood using cross-sectional methods. To analyze the maxillofacial characteristics of adult deepbite. Methods The sample included 159 children (with average age of 12.47 years old) and 81 adults (with average age of 21.76 years old) with class Ⅲ deepbite. The control group consisted of 51 normal individuals (with average age of 18.41 years old). Lateral cephalometric radiographs were taken and recorded in a computer through a scanner. Cephalometric measurements were conducted by using Winceph 7.0 software, and results were analyzed with SPSS 12.0 software. Results Significant differences between child and adult deepbite were observed in the following: N-ANS, ANS-Me, A-Ms, A-Ptm, Wits, Mo-Ms, Ii-Ii, A-B plane angle to the man-dibular plane angle, Gonial angle, L1 to NB length, overjet, mandibular body to anterior cranial base, Mo-Mi, posterior facial height, U1 to NA length, Pog-Go, Cd-Go, occlusion plane angle to SN, and U1 to SN. In addition, significant differences between adult deepbite and normal occlusion were observed in SNB, ANB, convexity, APDI, ODI, Wits, A-B plane to man-dibular plane, Gonial angle, overjet, mandibular body to anterior cranial base, S-Ptm, Mo-Mi U1 to SN; Pog-Go, Cd-Go, posterior cranial base, and occlusion plane to SN and posterior facial height. Conclusion  Deepbite patients have certain growth potential after puberty, but the sagittal relationship of their jaws exhibits no improvement. Adult deepbite patients exhibit significant problems in the vertical and sagittal jaw positions.
