Expression of artefacts from different orthodontic brackets and wires in cone beam computed tomography scans-an in vitro study.

Objectives: To investigate artefacts produced by different orthodontic brackets and wires in cone-beam computed tomography (CBCT) scans.

Materials And Methods: Two dental arches were made using extracted human teeth and plaster. Three pairs of acetate plates containing different brackets - metallic, ceramic, and self-ligating ceramic with NiTi clip - along with a control plate (i.
