The correlations between the sagittal jaw position and the cranio-cervical inclination are described in literature. Only few studies focus on the sagittal jaw position and the body posture using valid and objective orthopaedic examination methods. The aim of this study was to test the hypothesis that patients with malocclusions reveal significant differences in body posture compared to those without (upper thoracic inclination, kyphotic angle, lordotic angle and lower lumbar inclination).
Eighty-four healthy adult patients (with a mean age = 25.6 years and ranging from 16.1 to 55.8 years) were examined with informed consent. The orthodontic examination horizontal overjet (distance between upper and lower incisors) was determined by using an orthodontic digital sliding calliper. The subjects were subdivided in respect of the overjet with the following results: 18 revealed a normal overjet (Class I), 38 had an increased overjet (Class II) and 28 had an reversed overjet (Class III). Rasterstereography was used to carry out a three-dimensional back shape analysis. This method is based on photogrammetry. A three-dimensional shape was produced by analysing the distortion of parallel horizontal white light lines projected on the patient's back, followed by mathematical modelling. On the basis of the sagittal profile the upper thoracic inclination, the thoracic angle, the lordotic angle and the pelvic inclination were determined with a reported accuracy of 2.8 degrees and the correlations to the sagittal jaw position were calculated by means of ANOVA, Scheffé and Kruskal-Wallis procedures.
Between the different overjet groups, no statistically significant differences or correlations regarding the analysed back shape parameters could be obtained. However, comparing males and females there were statistically significant differences in view of the parameters 'lordotic angle' and 'pelvic inclination'.
No correlations between overjet and variables of the thoracic, lordotic or the pelvic inclination could be observed.
文献中描述了矢状位颌骨位置与颅颈倾斜度之间的相关性。仅有少数研究使用有效的客观正畸检查方法关注矢状位颌骨位置和身体姿势。本研究的目的是检验以下假设：与无错颌畸形的患者相比，错颌畸形患者在身体姿势方面存在显著差异（上胸段倾斜度、胸椎后凸角、腰椎前凸角和下腰段倾斜度）。
在获得知情同意后，对84名健康成年患者（平均年龄 = 25.6岁，年龄范围为16.1至55.8岁）进行了检查。使用正畸数字游标卡尺确定正畸检查中的水平覆盖（上下切牙之间的距离）。根据覆盖情况将受试者分为以下几组：18人覆盖正常（I类），38人覆盖增加（II类），28人覆盖反向（III类）。使用光栅立体摄影术进行三维背部形状分析。该方法基于摄影测量法。通过分析投射在患者背部的平行水平白线的变形，然后进行数学建模，生成三维形状。根据矢状面轮廓确定上胸段倾斜度、胸椎角、腰椎前凸角和骨盆倾斜度，报告的精度为2.8度，并通过方差分析、谢费检验和克鲁斯卡尔 - 沃利斯程序计算与矢状位颌骨位置的相关性。
在不同的覆盖组之间，未获得关于所分析的背部形状参数的统计学显著差异或相关性。然而，比较男性和女性，在“腰椎前凸角”和“骨盆倾斜度”参数方面存在统计学显著差异。
未观察到覆盖与胸椎、腰椎前凸或骨盆倾斜变量之间的相关性。
