Abstract

Objective: The aim of this study is to evaluate the effect of exposure parameters as milliampere
(mA) and field of view (FOV) in CBCT on metal artifact of dental implant, Can change of
milliampere (mA) and field of view (FOV) reduce the metallic artifacts in CBCT that result from
metallic structures?

Methodology: Four dry human mandibles with implants inserted in them, were scanned by using
Planmeca ProMax® 3D Mid CBCT machine, using different values of FOV and mA, without the
activation of MAR tool. Romexis® software was used for image analysis. For each implant linear measurements were measured (length & width), implants real length and width were used as gold standard.

Results: In general, the change of the size of FOV had no significant effect on metal artifacts
reduction (P > 0.05), Also; it was the same on mA values, there was no significant effect on metal artifacts reduction (P > 0.05).

Conclusions: According to the results of this study, Size of FOV and different values of mA
of CBCT have no significant effect on the metal artifacts around dental implants.
