Which point is defined as the intersection of the images of the posterior border of the condylar process of the mandible and the inferior border of the basilar part of the occipital bone?

The intersection of the images of the posterior border of the condylar process of the mandible and the inferior border of the basilar part of the occipital bone defines the point known as Articulare (Ar). This point is crucial in cephalometric analysis as it serves to help describe and measure the relationships between the skull and the mandible, particularly in assessing jaw positional relationships and articulations.

Articulare is located by identifying two key anatomical landmarks: the outline of the condylar process, which is part of the mandible that permits jaw movement, and the basilar part of the occipital bone, which contributes to the cranial base. The intersection of these two lines provides a reliable reference for cephalometric studies, particularly useful in orthodontics and oral surgery for treatment planning and assessing skeletal relationships.

In contrast, Sella refers to the midpoint of the sella turcica, Menton is the lowest point of the symphysis menti (the midline of the mandible), and Gonion represents the midpoint of the curve at the angle of the mandible. These points, while significant in their own right, serve different purposes in cephalometric analysis and are not defined by the intersection of the
