Figure 1.
Images used in the investigation derived from a treated case with maxillary lateral incisor agenesis managed using orthodontic space closure and canine substitution. Images were manipulated using Adobe Photoshop to show six (A–F) different combinations of gingival margin levels associated with the upper six maxillary anterior teeth. All manipulations were made using the maxillary central incisor interproximal contact and gingival margins as the midline (hatched black line) and vertical references (solid black line), respectively. The canines are substituting for the lateral incisors and the first premolars are substituting for the canines. The canine tips underwent enameloplasty during orthodontic treatment but no restorative work was carried out on any teeth.
