Abstract

BACKGROUND

For determining the cervical column curvature, the curve fitting method is the most precise method, but using this method in clinic seems to be difficult if not possible. In this study, we used a modification of cervical column inclination angle that has been already mentioned

OBJECTIVES

The aim of this study was to evaluate the posture and curvature of the cervical column introducing a modified constructed angle in order to evaluate the cervical column curvature in a relax position in relation to the jaws sagittal position.

PATIENTS AND METHODS

The lateral cephalometries of patients with no anomaly were taken in the natural head position. The mean age of the patients was 13.49 years including 56 female and 44 male. Steiner and Wits analysis was used to evaluate the sagittal position of the jaws. Modified constructed CVT/HOR and OPT/HOR angles were used to evaluate the cervical column posture and curvature. Patients were classified into three groups according to the angle's classification.

RESULTS

The results showed a significant positive correlation between modified constructed angles and sagittal jaw relationships (P < 0.05). Besides, in class II patients, there was a significant correlation between OPT/HOR and parameters ANB and Wits (P < 0.05 and P < 0.01, respectively). Age could not affect the curvature and posture of the cervical column.

CONCLUSIONS

According to the result of this study using modified constructed angles may be a simple method for evaluation of the relation between cervical column curvature and sagittal position of the jaws. There is significant correlation between cervical column posture angles and parameters ANB and Wits in Cl. II patients.

摘要

背景

在确定颈椎曲度时，曲线拟合方法是最精确的方法，但在临床中使用该方法即便可行似乎也很困难。在本研究中，我们对已提及的颈椎倾斜角进行了改良。

目的

本研究的目的是通过引入改良构建角来评估颈椎的姿势和曲度，以便在放松状态下相对于颌骨矢状位评估颈椎曲度。

患者与方法

对无异常的患者在自然头位下拍摄头颅侧位片。患者的平均年龄为13.49岁，其中女性56例，男性44例。采用Steiner和Wits分析法评估颌骨的矢状位。使用改良构建的CVT/HOR和OPT/HOR角来评估颈椎姿势和曲度。根据角度分类将患者分为三组。

结果

结果显示改良构建角与颌骨矢状位关系之间存在显著正相关（P < 0.05）。此外，在II类患者中，OPT/HOR与参数ANB和Wits之间存在显著相关性（分别为P < 0.05和P < 0.01）。年龄不会影响颈椎的曲度和姿势。

结论

根据本研究结果，使用改良构建角可能是评估颈椎曲度与颌骨矢状位关系的一种简单方法。在II类患者中，颈椎姿势角与参数ANB和Wits之间存在显著相关性。
