the SLOB rule and later confirmation by surgical exposure, there were 37 labially impacted canines, 26 palatally impacted canines, and 5 mid-alveolar impactions. 2007;131:44955. In these cases, the risk of tooth or root displacement into the maxillary sinus is high. affect the diagnostic quality of the images: anatomical superimposition and geometric distortion. Impacted canines may not be associated with any symptoms, and may be accidentally discovered during the routine radiographic examination, or during the investigation of other dental conditions. Although the exact cause of impacted maxillary canines remains unknown, multiple factors may play a role. Short-and long-term periodontal evaluation of impacted canines treated with a closed surgical-orthodontic approach. primary canines is performed in those cases, the crowding most probably will be solved by the movement of the adjacent teeth into the extraction space, Thilander B, Jakobsson SO (1968) Local factors in impaction of maxillary canines.

No difference in surgical outcomes between open and closed exposure of palatally displaced maxillary canines. (e) Palatal flap is outlined and reflected. or crowding at the PDC area is considered as a contraindication to extract the primary canines and wait until the PDC correct its position. 305. Used to determine where an impacted canine is located Can be used in vertical or horizontal parallax technique OPG + PA taken, or two PAs Although one Periapical radiographs are not accurate for determining the sector since any 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. treatment. 1.

The tooth may be elevated in toto, or may require sectioning if resistance is met (Figs. It is an area which has been extensively studied with regard to the various imaging modalities and their advantages. Conventional CT imaging is associated with high radiation dose and high cost. This chapter elaborates on canine impaction, keeping in mind the basic principles mentioned in the chapter on third molar impactions. Wolf JE, Mattila K (1979) Localization of impacted maxillary canines by panoramic tomography. In the extraction site in the group with the younger patients (10-11 years of age), the amount of space The apical third and palatal surface were commonly involved. sandiway.arizona.edu Other treatment alternatives may also be used in combination with the extraction of primary canines as expansion, distalization Ericson S, Kurol PJ (2000) Resorption of incisors after ectopic eruption of maxillary canines: a CT study. It goes by different terms, including Clark's rule, the buccal object rule and the same-lingual, opposite-buccal (SLOB) rule. Related data were Review. On the other hand, patients at 12 years old of age and above show a significantly less response to interceptive treatment [9,12-14]. 15.14ah and 15.15). - 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. reports. On the other hand, if the PDC position worsens in relation to sector or angulation, This indicated (Figure 3), while small resorption areas of grade 1 and 2 in the apical third of the root were misdiagnosed when using panoramic or periapical radiographs [36]. Tunnel traction of infraosseous impacted maxillary canines. eruption. help erupt impacted canines, these treatment modalities have a high degree of difficulty If the tooth lies close to the lower border of the mandible, an additional incision may be needed extra-orally for proper exposure. Of the 37 labially impacted canines, 31 (83.78%), 5 (13.51%), and 1 (2.7%) were in the coronal, middle, and apical zones, respectively. In all, 40.7 % and 26.1 % of the impacted maxillary canines were located buccally in males and females, respectively.

Maxillary canine is the second most commonly impacted tooth, after the mandibular third molar. Br Dent J. 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 are one of the common problems encountered by the oral surgeon. The VP technique requires panoramic and anterior occlusal radiographs [15,16]. 15.3). at age 9 (Figure 1). Premolars, incisors and other teeth may be impacted but most of the surgical principles and approaches mentioned for canine can be applied to them as well. On comparing the buccal object rule and panoramic localization techniques in these patients, it was found Chaushu et al. This will make any object that is buccal/facial of the teeth automatically farther from the film/sensor. Angle Orthod. 1935;77:378. About 50% of maxillary incisors adjacent to PDC show root resorption [35]. Thick palatal bone and mucoperiosteum, which can obstruct eruption of palatally oriented canines.

If non-palpable canines unilaterally or is needed and the patient should be recalled after additional 6 months. A hole is created in the root and an elevator is used to engage this and remove the root. At the age of 11, only 5% of the population has non-palpable or non-erupted canines unilaterally or bilaterally. Indications include: This option is only considered when other options are not feasible or have failed. J Contemp Dent Pract 14:153-157.

Not only that the CBCT technique is more costly than the conventional radiographs as it costs happen. Closed eruption technique: If the impacted canine lies in the middle of the alveolus, near the nasal spine, or high in the buccal vestibule or the palate, this technique may be indicated (Vermette et al., 1995) [19].

Periodontal health of orthodontically extruded impacted teeth: a split-mouth, long-term clinical evaluation. 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]. The Orthodontic Treatment of Impacted Teeth. This method may pose a risk of haemorrhage from the nasopalatine vessels which can, however, be controlled by pressure pack or by electrocautery.
