Gonial Angle

The gonial angle is the angle formed where the lower jaw (mandible) curves upward at the back, near the area called the gonion. It is measured between the lower border of the mandible and the rear part of the jaw's vertical branch. This angle helps in understanding the shape and size of the jaw, which can affect facial appearance, bite, and jaw function. Dental and medical professionals often assess the gonial angle during orthodontic evaluations and jaw surgeries to plan treatments and diagnose certain conditions. It’s an important anatomical feature that reflects the overall structure of the lower face.
