Still University, Mesa, when this article was written. The flap is designed in such a way that vertical incisions are placed on the soft tissue at the distal side of the lateral incisor and at the mesial side of the first premolar. For example, when extraction of permanent tooth is needed to create space for PDC
The incision is initiated in the gingival margin on the palatal side from the ipsilateral first premolar and, depending on the position of the impacted tooth, is extended up to the contralateral lateral incisor or premolar. or the use of a transpalatal bar. in 2012 have brought out a useful classification of maxillary canine impactions based on which the exposure technique may be decided [25].

Eur J Orthod 25: 585-589. The next follow-up is one year after the intervention. - Early intervention/extraction of deciduous canines (before or latest at 11 years of age) and/or canine position in sector 1-3 will give the best results.

Chaushu et al postulated that if the ratio of the canine to the central incisor is greater than or equal to 1.15, the canine is likely palatally positioned.11 Third option is to look for canine superimposition on the root of the central incisor, as proposed by Wolf and Mattila.12 As per their rule, if impacted maxillary canine is superimposed . -
If there is haemorrhage, it can usually be controlled by pressure application. Orthodontic reasons, such as the need to move an adjacent tooth into the area of impaction.

However, since CT exposes the patient to a high dose of radiation, the unfavourable relationship between cost and benefit to the patient determines its use only in particular cases, such as in the presence of craniofacial deformities.

This method can be applied effectively only when the canine is not rotated, does not touch the incisor root and the incisor is not tipped [11]. To prevent soft tissue regrowth over the exposed crown, a pack (such as a perio pack or roller gauze impregnated with iodoform or antibiotics) may be inserted or sutured in place. Crown deeply embedded in close relation to apices of incisors. If the beam angle moves mesially, then the image of the impacted canine moves mesially too. referred to an orthodontist for evaluation of the best treatment method. A mnemonic method for remembering this principle is the SLOB rule (same lingual opposite buccal). Except the third molars, maxillary canines are among the last teeth to erupt. Alqerban A, Hedesiu M, Baciut M, Nackaerts O, Jacobs R, et al. 1995;65(1):2332. Palpation should be done at the canine area labially, then moving the finger upward to the vestibule high as much as possible (Figure 2) [2]. Schmidt AD, Kokich VG. Radiographic examinations may include periapical X-ray with cone shift technique, occlusal radiography, anteroposterior and lateral radiographic views of maxilla, OPG, CBCT, CT scan.
