Abstract
Impaction of maxillary central incisors are only seldom encountered in
clinical practices. Impaction of permanent anterior teeth results in both aesthetic
impairment and functionally compromised occlusion. Careful planning and
interdisciplinary approach are required for the successful management of impacted
central incisor. The present case report highlights a case where patient reported with a
missing left central incisor, at the age of 9 years and 2 months. A palpable crown
prominence on labial gingival mucosa in the vestibule was suggestive of the impacted
maxillary central incisor. On Cbct examination 21 was located below the nasal floor
with long axis of the tooth near parallel to palatal plane. The crown of the impacted 21
faced labially at the level of middle third of the root of 11. The root formation was
incomplete. The crown of the impacted teeth was exposed with the help of a diode laser
under LA. A lingual button is bonded on the palatal surface of the exposed crown. PAE
brackets are bonded to 12, 11 and 22 with slot alignment. E- thread is tied from the
monkey loop from the attachment of exposed crown to the 0.018 special Autsralian base
archwire. Traction was progressively continued till a PAE bracket could be bonded
followed by a piggy back traction by 0.014 Niti. Case was finished with disimpacted 21
in alignment with the arch. Disimpaction and alignment of incisor achieved by a
minimally invasive technique was successful and showed good stability.
