为了探讨中国人 Bonwill's 三角的具体情况,本文以26例髁突完好、牙列较完整的中国成人下颌骨为对象,对下颌中切牙至两侧髁突的距离以及髁突间距进行了测量和统计学处理。从测量和统计结果看,Bonwill 三角形的边长在不同个体之间相差相当显著;而同一个体 Bonwill 三角形三个边长之间在统计学上还不能说有显著性差异,即可以近似地看成等边三角形,但实际上绝大多数中国成人的Bonwill 三角形基本上属于等腰三角形。
In order to investigate the Chinese Bonwill's trigonometry, we measured the distance between the mandibular incisor and the condyles and the distance between the condyles in 26 adult mandibular congenital intact mandibles Statistical analysis. From the measurement and statistical results, the side length of the Bonwill triangle is quite significant among different individuals; while the statistical statistics of the three sides of the Bonwill triangle of the same individual can not be said to be statistically significant Equilateral triangles, but in fact most Chinese adults Bonwill triangles basically belong to the isosceles triangle.
