Review. greater successful eruption in comparison to sector 3 and 4. Two periapical or periapical with anterior occlusal radiographs are the radiographs needed to perform HP This is because the crown of the developing permanent canine lies just palatal to the apex of the primary canine root. The incidence of impacted upper canines has been reported around 1/100 [4], in addition, when impacted, canines have been found to overlap the adjacent lateral incisor in almost 4/5 of cases [5]. Ectopic canines should be identified early through effective clinical and radiographic examination. However, it is important to note that all cases in this study had a mild crowding and small space deficiency (< 4mm). It is also not uncommon to have the likelihood of creating a communication between the oral cavity and antrum, which may lead to post-operative nasal bleeding. . prevent them by means of proper clinical diagnosis, radiographic evaluation and timely (c) Drill holes placed in the cortical plate overlying the crown so as to expose the crown, after the full exposure of the crown, elevator is applied beneath the crown to mobilize the tooth, (d) If the tooth is resistant to elevation, the crown is sectioned using bur and it is removed, (e) Cavity created following removal of crown, (f) The root is moved into the space created by the removal of the crown and it is then removed.

This may be done by utilizing the socket of deciduous canine or first premolar, depending on the amount of space needed and available. Adding to If the root is >75% formed, the likelihood of requiring root canal treatment increases. accuracies [36]. orthodontist. If the tooth lies close to the lower border of the mandible, an additional incision may be needed extra-orally for proper exposure. Not only that the CBCT technique is more costly than the conventional radiographs as it costs It generates more radiation compared to the conventional technique [34]. Alternately, a horizontal incision may be made below the attached gingiva. Accordingly, if the impacted canine is located buccally, the crown of the tooth moves mesially. 2007;131:44955.

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. If the impacted canine is close to the alveolar crest, or if a broad band of keratinized tissue covers the tooth, a surgical window may be created.

This chapter elaborates on canine impaction, keeping in mind the basic principles mentioned in the chapter on third molar impactions. For attempting this technique, the case must fulfil the following criteria: The impacted canine must be favourably positioned. On the other hand, PDCs in sector 3 and 4 have a lower success rate, which equals 64% [9]. Community Dent Oral Epidemiol 14:172-176. If not, bone is removed to expose the root.
