Fig. 6From: Implementation of iterative metal artifact reduction in the pre-planning-procedure of three-dimensional physical modelingPatient acquired without jaw spacer and no iterative metal artifact reduction algorithm (MAR) showing extensive metal artifact affecting the display of the frontal upper teeth (a). The segmented extensive metal artifact had a volume of 36 ml (b). The use of MAR (c) reduced the metal artifact by 90.8% (d). In addition, MAR allowed a better dental displayBack to article page
