Fig.7: a) Pre- and Post-treatment cephalometric tracings superimposed on the SN plane at S: showing no movement of the posterior dentition and extrusion of the anterior dentition. b) Dental changes as seen in the ClinCheck™ software.
Following the treatment, a fixed lingual retainer was placed on the lower arch in addition to the Vivera™ retainers on the upper and lower arches to prevent further posterior extrusion and facilitate minimal anterior extrusion in order to overcorrect the overbite. Post retention pictures after a year showed minimal tooth movement and well aligned teeth. (Fig. 8)
