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.
