Tunnel traction of infraosseous impacted maxillary canines. Subsequently, after locating the crown of the impacted tooth, the flap may be sutured back into at the apical end, while the crown is exposed to the oral cavity (Fig. reports. Resorption of incisors after ectopic eruption of maxillary canines: a CT study. The case must be evaluated carefully for proper diagnosis and treatment planning. Along the incision arms, flaps are elevated on four sides so that the crown is uncovered. An orthodontic bracket may be bonded to the crown and to the bracket, a traction wire is affixed.

They selected only studies that pertained to the prevalence, etiology and group. If there is any resistance during elevation, the tooth must be sectioned, so that the fragments can be removed easily. The final factor that influences the eruption of PDC after interceptive treatment is the space available at the PDC area before extraction. On the other hand, if the canine moves to the opposite direction, it indicates buccal canine position. Drawback of this technique is that the tooth cannot be inspected directly once the flap has been sutured (Fig. The canine would be palatally placed if the ratio of the sizes between the canine and the central incisors is 1.15 or greater. The palatally impacted canine is three times more likely to occur in females than males and is two times more likely to be unilateral versus bilateral.

In cases of unilateral impaction, instead of extending the incision to the contralateral side, a vertical incision may be given in the mid palatal region.

The SLOB Rule Explained, by Endodontist Dr. Sonia Chopra Watch on A lot of times when we're doing a root canal you have two canals that are superimposed on each other, specifically the buccal and the lingual canals in a tooth like a lower molar. A buccal flap must ideally be used for surgical access, as a lingual flap may not provide adequate access, and is associated with increased post-operative morbidity. As the buccal object rule states that the buccally located object moves in the direction of the x-ray beam, on changing the direction of x-ray beam, the position of the impacted canine can be determined. 305. The SLOB rulestands for same lingual opposite buccal: If the object (impacted tooth) moves in the same Canines in sectors 2 and 3 had significantly

Kuftinec [12, 13] asserts that if the canines cusp is mesially at the root of the lateral incisor, the impaction is probably palatal but if the cuspid is found overlapping the distal half, a labial impaction is more probable.

This is because increasing age increases the difficulty of the procedure, and by removing early, damage to the adjacent structures may be minimized. Impacted canines that are malpositioned, but have a favourable root pattern (without hooks or sharp curves) may be considered for autotransplantation into the dental arch. It may also be considered when a patient is not willing for orthodontic treatment or cannot afford it, even if the impacted tooth is in a favourable position. Google Scholar.
