3. ANATOMIC LANDMARKS OF THE MANDIBULAR REGION

Radiopaque landmarks

Coronoid process (Fig. U12) is the thin, triangular‐shaped process of the anterosuperior aspect of the ramus. Its triangular shape resembles the dorsal fin of a shark. This mandibular landmark is typically observed in extraoral images. However, it may also appear in maxillary molar periapical images. This can occur because the mandible must swing open to accommodate the intraoral receptor holder. In so doing, the coronoid process rotates anteroinferiorly and often becomes superimposed over the maxillary molar tuberosity region. The coronoid process appears as a homogeneous triangular radiopacity.
