Recently, researchers such as Zhu Xiaohong, Han Jingying and Liu Jie from the Department of Orthodontics, the Second Affiliated Hospital of Harbin Medical University, jointly published a paper. The purpose of this study is to use a new cephalometric method – W angle to evaluate the sagittal relationship of maxilla and mandible, and analyze the W value of three types of angle’s errors This study pointed out that w angle can reflect the sagittal misalignment of the maxilla and mandible, and has good repeatability.

In this study, 153 patients aged 11-20 years were studied by cephalometric analysis. According to anb angle, wits value and beta; angle, they were divided into three groups. The mean value and standard deviation were taken to analyze the difference between men and women
The result of this study is to analyze the normal value of W angle in patients with angle’s three types of malocclusion; the difference of W value among the three groups was statistically significant (P < 0.05); the W value of each group had no significant difference in gender
