The size of the Balkwill angle and the height of the Bonwill triangle.
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.
