Impacted upper canines: examination and treatment proposal based on 3D versus 2D diagnosis.

Aim: The purpose of this diagnostic cross-over study was to evaluate whether three-dimensional (3D) diagnostics (cone-beam computed tomography, CBCT) was superior to two-dimensional (2D) diagnostics (panoramic X-ray, OPG) in patients with impacted upper canines for assessing their position and the probability of their alignment.

Materials And Methods: Panoramic X-rays, CBCTs, and study casts of 21 patients with a total of 29 impacted maxillary canines were analyzed. Patients with syndromes or tooth aplasias were excluded.
