Common orthodontic appliances cause artifacts that degrade the diagnostic quality of CBCT images

Matthew A Sanders et al. J Calif Dent Assoc. 2007 Dec.

Abstract

Objective: This study evaluates artifacts generated by orthodontic brackets in CBCT images.

Methods: Cadaver heads with restoration free dentitions were prepared. CBCT scans with four orthodontic bracket materials utilizing thermoplastic carriers and a control were compared in three phases.

Results: Stainless steel brackets caused statistically significant (P<0.0001) differences from the control in the three phases.

Conclusion: These observations support the hypothesis that metallic and nonmetallic orthodontic brackets interfere with the diagnostic quality of CBCT images.
