On examination, the following factors were revealed: class I malocclusion, overjet of 4.0 mm, mild overbite, diastema between the central incisors of 9 mm (the mother reported that the extraction of a mesiodens was performed at the age of 8), diastemas between the central and lateral incisors and between the lower incisors, a labial frenulum with a low insertion, and rotation of the incisors (Figures 1 and 2).

The appliance was removed, and a flat wire segment was bonded into the palatal surfaces of both central incisors with the intention of being maintained until complete eruption of the canines (Figures 4 and 5).
