Figure 4
The artifacts reduction ratio (%) is calculated to compare to the prosthesis type. The ratio was calculated as the edge reduction ratio (%) = \(\left(\frac{{\rm{Edges}}\,{\rm{in}}\,{\rm{MARoff}}\,{\rm{image}}\,-\,{\rm{Edges}}\,{\rm{in}}\,{\rm{MARon}}\,{\rm{image}}}{{\rm{Edges}}\,{\rm{in}}\,{\rm{MARoff}}\,{\rm{image}}}\right)\times 100\). Note that gold crown shows the highest reduction ratio with significance regardless of scanning condition. The significance in reduction ratio difference is noted with asterisk. *P-values are calculated using an one-way analysis of variance (ANOVA) with Welch’s F correction (p < 0.05).
