The Importance of Knowing Normal Anatomy in CBCT Scans

The acquisition of CBCT scans is probably one of the most mundane tasks, but it is an important part of the imaging process. Post-acquisition involves viewing and interpreting the scans. Although the maxillofacial region is complex, by virtue of familiarity, most dentists can interpret this area very efficiently despite the complex nature of anatomy and variances in this region. Understanding what is considered normal is the first step to identifying abnormalities that could pose a challenge in the treatment planning.

Normal anatomy can be broadly divided into the maxillary and mandibular regions.

When visualized, the upper regional anatomy is comprised of (but not limited to) the bilateral maxilla, as well as the nerves and vascular supply of the region and the maxillary sinus and other paranasal sinuses (in part or full, depending on the field of view). Along with these areas, the, Osteomeatal complex and orbits are the most significant.
