OBJECTIVE
To test the hypotheses that (i) there is a significant correlation between the curve of Spee (COS), basal arch (WALA ridge) to dental arch distance (WALA-FA distance) and curve of Wilson (CW) and that (ii) the deepening of the COS is affected by the CW and the WALA-FA distance.
METHODS
Mandibular models of 50 patients aged between 20 and 35 years were scanned with TRIOS. The xyz coordinate system was determined, and a reference occlusal plane was generated. The depth of the COS, the CW, and WALA-FA distance were measured using an engineering software.
RESULTS
The greatest difference in the measurement of the depth of the COS between the right and left was found to be 0.41±0.50 mm in the first molar teeth. On the basis of the results of Pearson correlation analysis, there was no strong correlation between the depth of the COS, the CW, and the WALA-FA distance.
CONCLUSION
It was shown that there was no strong correlation between the depth of COS, CW, and WALA-FA distance. The CW and WALA-FA distance could not be effective in the deepening of the COS.
目的
验证以下假设：（i）司皮曲线（COS）、基骨弓（WALA嵴）至牙弓距离（WALA-FA距离）与威尔逊曲线（CW）之间存在显著相关性；（ii）COS的加深受CW和WALA-FA距离的影响。
方法
使用TRIOS对50名年龄在20至35岁之间患者的下颌模型进行扫描。确定xyz坐标系，并生成一个参考咬合平面。使用工程软件测量COS的深度、CW和WALA-FA距离。
结果
发现第一磨牙处COS深度测量的左右最大差异为0.41±0.50毫米。根据Pearson相关性分析结果，COS深度、CW和WALA-FA距离之间没有强相关性。
结论
结果表明，COS深度、CW和WALA-FA距离之间没有强相关性。CW和WALA-FA距离对COS的加深无效。
