Supernumerary tooth (11A) palatal to tooth 21

A small geminating supernumerary tooth (11A) with two crowns is present on the maxillary midline. The larger crown of the supernumerary tooth is located palatal to the apical half of the root of tooth 21 and the smaller crown slightly impinges upon the maxillary incisive canal.

No damage or displacement has occurred to teeth 11 and 21.

The root of the supernumerary tooth is fully developed and exhibits malformation. The periodontal ligament space is of uniform width around the tooth and the lamina dura is intact, which suggests that the tooth is not ankylosed.

The supernumerary tooth can be surgically accessed from the palatal aspect of the alveolar crest in the region palatal to the root of tooth 21.

Axial views of the supernumerary tooth (11A)

These axial cross-sectional images demonstrate that the periodontal ligament space lining the root circumference of this supernumerary tooth is visualized, which suggests the absence of ankylosis.

Normal tooth 21

Tooth 21 is unaffected by the supernumerary tooth. The crown of the supernumerary tooth is positioned palatal to the apical half of the root of tooth 21.

Normal tooth 11

Tooth 11 is unaffected by the supernumerary tooth. The supernumerary tooth is located mesiopalatally to the apical half of the root of tooth 11.

Axial views of the anterior maxilla

These axial cross-sectional measurements demonstrate the palatal position of the supernumerary tooth to the apical half of the root of tooth 21. No damage or displacement has occurred to any of the permanent teeth in this region. The smaller crown at the mesial aspect of the tooth slightly impinges upon the maxillary incisive canal.
