Fig. 4From: Effects of different patterns of movement for correcting a deep curve of Spee with clear aligners on the anterior teeth: a finite element analysisTrends in total displacement (mm) of the dentition for each configuration. Arrows indicate the direction of tooth movement;Â (a) Configuration A, (b) Configuration B, (c) Configuration C, (d) Configuration D and (e) Configuration E. the color intensity reflects the magnitude of tooth movement, with cooler hues indicating smaller movement trends and warmer hues indicating greater movement trends Back to article page
