The Balkwill angle and the height of the Bonwill triangle were measured on cephalograms of 128 adult females and males who had all their natural teeth. The size of the Balkwill angle was dependent on the choice of the condylar reference point, whereas the height of the Bonwill triangle was not. When analysed by sex, it was found that the Balkwill angle was larger in males than in females. Likewise, the height of the Bonwill triangle was larger in males.
在128名拥有全部天然牙的成年女性和男性的头颅侧位片上测量了Balkwill角和Bonwill三角的高度。Balkwill角的大小取决于髁突参考点的选择，而Bonwill三角的高度则不受此影响。按性别分析时发现，男性的Balkwill角大于女性。同样，男性的Bonwill三角高度也更大。
