What is the curved part of the mouth,

Curved surface tomography is a common examination method for oral cavity.

The main purpose is that it can see all your teeth.

Therefore, patients with periodontitis will routinely do a comprehensive tomographic scan.

In addition, we can see whether the temporomandibular joint, maxilla and alveolar bone are absorbed by flexion.

It is equivalent to a normal scan from the nose to the mandible. It's a plan, and you can't see the three-dimensional structure. So you need to do some other tests after you find the problem.
