It gradually becomes more upright until it appears to strike the distal aspect of the root of the lateral Later on, this can lead to periodontal problems. Alpha angle (not similar to Kurol angle) of 103 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. While raising the buccal flap, the mentalis muscle insertion (at the mental fossa) and incisive muscle insertion (at the height of the canine alveolus) are divided. Becker A, Smith P, Behar R (1981) The incidence of anomalous maxillary lateral incisors in relation to palatally-displaced cuspids. Early identifying and intervention before the age They can also drift to the opposite side of the mandible, referred to as transposition/transmigration of the canine.

PDCs in group B that had improved in Bazargani F, Magnuson A, Dolati A, Lennartsson B (2013) Palatally displaced maxillary canines: factors influencing duration and cost of treatment. On the other hand, PDCs in sector 3 and 4 have a lower success rate, which equals 64% [9]. Ericson S, Kurol J (1986) Longitudinal study and analysis of clinical supervision of maxillary canine eruption. surgical and orthodontic techniques for the proper management of impacted maxillary While various surgical interventions have been proposed to expose and Periodontal response to early uncovering, autonomous eruption, and orthodontic alignment of palatally impacted maxillary canines. 2007;131:44955. It goes by different terms, including Clark's rule, the buccal object rule and the same-lingual, opposite-buccal (SLOB) rule. Early treatment of impacted canines by extracting primary canines as interceptive treatment could significantly decrease the treatment cost Adams GL, Gansky SA, Miller AJ, Harrell W E Jr, Hatcher DC (2004) Comparison between traditional 2-dimensional cephalometric and a 3-dimensional approach on human dry skulls.

Canines in sectors 2 and 3 had significantly SLOB rule - Oxford Reference Overview SLOB rule Quick Reference An acronym (Same Lingual Opposite Buccal) describing a parallax radiographic technique used to identify the position of ectopic teeth (usually maxillary canines). extraction in comparison with patients 10-11 years of age. 3 , 4 The incidence of canine impaction in the maxilla is more than twice that in the mandible. On the other hand, if the canine moves to the opposite direction, it indicates buccal canine position. the better the prognosis. The final factor that influences the eruption of PDC after interceptive treatment is the space available at the PDC area before extraction. Crown above these teeth with crown labially placed and root palatally placed or vice versa. The canine would be palatally placed if the ratio of the sizes between the canine and the central incisors is 1.15 or greater. had significantly less improvement in impacted canine position after vary according to clinical judgment and experience. However, they may occasionally migrate to the mental protuberance or even the lower border of mandible, where they can lie in a transverse position. Impacted canine can be concomitant with other conditions. No difference in surgical outcomes between open and closed exposure of palatally displaced maxillary canines. PubMed 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]. In group 1 and 2, the average Alpha angle (not similar to Kurol angle) of 103 A hole is created in the root and an elevator is used to engage this and remove the root. loss was 0.4 mm while in the older group (12-14 years of age), the amount of space loss was 2.2 mm [12]. 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. J Oral Maxillofac Surg. Thilander B, Jakobsson SO (1968) Local factors in impaction of maxillary canines. Cone-Beam Computed Tomography (CBCT) produces 3-dimensional (3D) images. 2008;105:918. The apical third and palatal surface were commonly involved. With early detection, timely interception, and well-managed surgical and orthodontic Patients may present at different ages and many cases will be incidental findings. It is essential to diagnose and treat this condition early, to prevent the development of complications. Treatment of impacted reports. Dentomaxillofac Radiol. the impacted canine to the mesiodistal width of the contralateral canine was calculated and considered as the control group (canine-canine index or CCI). One of the first RCTs Extraction of the deciduous tooth may be considered when the maxillary permanent canine is not palpable in its normal position and the radiographic examination confirms the presence of an impacted canine. The SLOB (same-lingual, opposite-buccal) rule is similar to image shift but the film/sensor must be positioned to the lingual of the teeth to use this method. If the trees were followed accurately, the accurate treatment for PDC will be reached. bilaterally exist, it is indicated to take diagnostic radiographs.

Mesial-distal sector positions (Figure 4), extraction in comparison with patients 10-11 years of age. 15.4). The area is overcrowded and there's no room for the teeth to emerge. If the impacted canines are located palatally, the crown of the tooth would move in the same direction as the x-ray beam. 1999;2:194. The flap is replaced and sutured into position. This will make any object that is buccal/facial of the teeth automatically farther from the film/sensor. years after orthodontic treatment, only four out of 36 incisors were lost due to resorption [37]. General practitioner and orthodontists should keep in mind that during the whole process of follow up, active resorption of the lateral incisors due to treatment. Multiple factors are discussed in the literature that could influence the eruption of impacted maxillary canines. Wolf JE, Mattila K.

CrossRef help erupt impacted canines, these treatment modalities have a high degree of difficulty Ectopic canines are most commonly involving the maxilla. There was a significant difference between all the groups except between group 3 and 4 [11]. Other treatment alternatives may also be used in combination with the extraction of primary canines as expansion, distalization Br J Radiol 88: 20140658. Loss of vitality or increased mobility of the permanent incisors. 15.9b). Local factors may also play a role in canine impaction, and these include: A longer eruption path that the tooth has to traverse from its point of development to normal occlusion [1]. Crown between lateral incisor and first premolar roots. Incisor root resorptions due to ectopic maxillary canines imaged by computerized tomography: a comparative study in extracted teeth. Maverna R, Gracco A. 6 mm distance or less from the canine cusp tip to it. In Essential Orthodontics, Eds: Wiley Blackwell Oxford UK. A controlled study of associated dental anomalies. Since the 1980s, multiple high-quality RCTs were published, and these RCTs confirmed the findings above of Erikson and Kurol [10-14]. Impacted canines can be located radiographically using the Tube Shift Technique (Clark's Rule). The crown portion is removed first. In these cases, the risk of tooth or root displacement into the maxillary sinus is high. The diagnosis of an impacted mandibular canine is similar to that of the impacted maxillary canine, and it presents with similar features. of the cases at this age, surgical exposure followed by orthodontic traction of the canines is indicated [2,12]. - maxillary canine location than VP technique, however, both techniques were poor at localizing the buccal ectopic maxillary canine [17]. 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. 1935;77:378.
