case_images: In order to make an objective assessment and choose which pair of incisors to be surgically extracted to alleviate the accumulation, a CBCT examination was ordered (Figure 1).

case_images: After extraction of the temporary and redundant incisors, the two ectopically located incisors spontaneously changed their position and erupted (Figure 2).

case_images: A follow-up with subsequent X-ray ascertained a double tooth (Figure 6).
case_images: Development of the lower dental arch. (a) Initial state. (b) After extraction of temporary first molars. (c) Placed lingual arch. (d) Eruption of the lower right first and second premolars and left first premolar:double tooth. (e) Spontaneous eruption of the lower left second premolar, after extraction of tooth 34. (f) Complete eruption of the lower left second premolar.

case_images: The orthodontic treatment plan included the following: extraction of double tooth 34, preservation of the perimeter of the lower dental arch, levelling of the two dental arches, and normalization of the occlusion (Figure 7).
case_images: CBCT: 3D vestibular and lingual view and transverse sections.
