Teeth position .

  • Delayed eruption: is the emergence of a tooth into the oral cavity at a time that deviates from normal.
  • Transposition: two adjacent teeth  exchanged positions in the dental arch.
  • Ectopic eruption: is a disturbance in which the tooth does not follow its usual course.
  • Submersion: it occurs when a previously erupted tooth becomes embedded in the oral tissues.

Case 1

Horizontally impacted / misplaced canine. The crown of the impacted canine has penetrated the buccal cortical plate.

Case 2

Ectopic buccal eruption of the left 3rd molar.

Case 3

Ectopic impaction of 2nd premolar (25).

Case 4

Various cases of unerupted/impacted teeth.

Case 5

Palatally impacted right central incisor (11).

Case 6

Secondary impaction of the deciduous molar (with carious lesion) causing impaction of 2nd premolar (35).

Case 7

Delayed eruption of upper lateral incisor.

Case 8

Submersion of the lower right 2nd deciduous molar (infra-occlusal position).

Case 9

Male 16 years old.
In the upper jaw, 1st right premolar (14) is impacted and located in the position of the canine 13 (Transposition). Extensive internal resorption at the palatal surface of the root of the impacted premolar is observed (arrows).
