Esthetic perception of maxillary lateral incisor agenesis treatment by canine mesialization

Regarding the space closure treatments, although all groups regarded simple dental reshaping of the canine to be attractive, the dental professionals considered gingival and crown reshaping to be more esthetic. In contrast, laypersons were not significantly responsive to this dental and gingival modification as compared to only slight reshaping of the mesial edge of the cusp of the mesialized canine in MLIA.
