The Gonial Angle is significant in orthodontics as it specifically reflects the relationship between the ramus and the body of the mandible. This angle, formed by the intersection of the ramus plane and the occlusal plane, provides essential information regarding the growth patterns and the structural configuration of the mandible. A steep Gonial Angle indicates a more vertically oriented mandible, which may relate to various dental and skeletal conditions. Conversely, a less steep angle could indicate a more horizontal orientation, which can have implications for the occlusion and overall facial aesthetics. Understanding the Gonial Angle helps orthodontists assess the configuration of the jaw and make informed decisions regarding treatment planning and diagnosis.

This focus on the relationship between the ramus and body of the mandible is crucial for evaluating mandibular morphology rather than broader relationships like those between teeth and jaw or the position of the maxilla, which are not specifically indicated by the Gonial Angle.
