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. consideration of space between the lateral and first premolar and camouflaging appropriately. incisor. Possible indications and requirements include: Ideally, this should be carried out prior to complete root formation. the midline indicates surgical exposure (equal to sector 4). Because of the significance of maxillary canines to aesthetics and function, such decision can have very serious consequences. Katsnelson [15] et al. A split-mouth, long-term clinical evaluation. Patient age at the time of diagnosis of PDC is very important in relation to the prognosis of spontaneous correction and eruption.

Diagnostic radiographs are indicated if: - One or both canines are not palpable buccally above the root of maxillary primary canines or lower first or second premolars have erupted while the at age 9 (Figure 1). This involves taking two radiographs at different angles to determine the buccolingual. Scarfe WC, Farman AG (2008) What is cone-beam CT and how does it work? reports. If the impacted canines are located palatally, the crown of the tooth would move in the same direction as the x-ray beam. Field HJ, Ackerman AA. This is because increasing age increases the difficulty of the procedure, and by removing early, damage to the adjacent structures may be minimized. Baccetti T, Sigler L M, McNamara JA Jr (2011) An RCT on treatment of palatally displaced canines with RME and/or a trans palatal arch.

Alternately, a horizontal incision may be made below the attached gingiva. Treatment of a patient with Class II malocclusion, impacted maxillary canine with a dilacerated root, and peg-shaped lateral incisors. Impacted canine can be concomitant with other conditions. The mucoperiosteal flap is elevated and the bone with the tooth bulge is exposed. If it is relatively small, it is located further away from the tube (labial). The impacted upper Cuspid. In this post, we will look at examining and potential methods of management for ectopic canines. 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].
