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)
