The angle of jaw is a term used in anatomy to describe the specific angle formed by the meeting point of the lower jawbone (mandible) and the side of the skull, just below the ear. It is also referred to as the mandibular angle or gonial angle. This angle is a key anatomical landmark in various medical and dental fields.
The angle of jaw plays a significant role in determining facial structure and aesthetics. In individuals with a well-defined and prominent angle of jaw, it contributes to a broader and more defined lower face. The angle of jaw is essential in determining the shape of the lower face, particularly the jawline and chin.
This anatomical feature is important in various dental procedures, such as orthodontics, oral and maxillofacial surgery, and dental implantology. It provides a reference point for assessing and modifying the position of the lower jaw, as well as determining the positioning and alignment of the teeth.
Moreover, the angle of jaw is crucial in identifying certain medical conditions. Changes in the angle may be indicative of skeletal abnormalities, such as temporomandibular joint disorder (TMJ), jaw asymmetry, or jaw fractures. It is also considered during facial reconstructive surgeries, as alterations in the angle of jaw can significantly impact facial symmetry and overall appearance.
Understanding the angle of jaw is vital in the fields of anatomy, dentistry, and medicine, as it serves as a fundamental component of facial structure, dental treatment planning, diagnosis, and aesthetic assessment.
