• Determination of the extent of lesions, tumors, cysts, etc., which cannot be fully
visualized on plain films.
• Identifying the relationship of the inferior dental canal to a tooth/lesion that is to be
removed.
• Visualization of 3D anatomy of the alveolar clefts.
• Diagnosis of un-erupted teeth, third molar teeth, and odontomas.
• Diagnosis of third molar teeth is only available in some Asian countries and
Mexico.
• Diagnosis of root resorption of teeth.
• Assessment of cleft palate.
• Assessment of complex root canal anatomy.
• Diagnosis of periapical pathology.
• Diagnosis of vertical root fracture.
• Assessment of fractures on maxilla, mandible, and fractures of teeth where plain
film imaging is equivocal.
• Reconstruction of position, malformations, and fractures of maxilla & mandible
bones and nasal bone as 3D pictures for operational planning and patient
education.
