“…50 In a recent analysis by Ferguson et al on 151 palatally impacted teeth, 51 they found that this method around the impacted teeth will provide 2 to 4 times increase in the rate of tooth movement compared with closed exposure. 51,52 It includes performing ostectomy between the adjacent teeth to provide a pathway from the impacted canine crown to the final archwire position but leaving about 1.5 mm of bone interproximally. Furthermore, it should be followed by penetrations over the root prominence of the impacted tooth toward movement direction.…”

“…Furthermore, it should be followed by penetrations over the root prominence of the impacted tooth toward movement direction. 51 Outcome evaluations: open vs closed surgeries. In terms of periodontal health, Parkin et al has concluded that these two techniques present no impact on the prognosis of the palatally impacted canines after the treatment.…”

Aim: This study aimed to overview and collect the current trends and techniques in managing maxillary impacted canines by retrieving recent literature, in a chronological manner from the prevention to the very late stages of treatment in adults. Background: We performed a review on the recent literature regarding the current trends on the management of impacted canines. We have researched various types of available articles such as clinical trials and case presentations, meta-and systematic analyses, and literature reviews focusing on clinical management of impacted canines and their outcome evaluations. We adhered to those articles published within the last decade with a focus on treatment planning for impacted and displaced canines. Review results: Depending on the diagnosis and its timing of it, a maxillary impacted canine can be managed by either prevention or interception, surgical opening followed by autonomous eruption or orthodontically traction, autotransplantation, and at last by removal and space closure. These techniques are elaborated one by one according to the age and severity of the diagnosis. Conclusion: Impaction of the canines is a manageable abnormality which is highly dependent on the timing and localization of the displaced tooth. Early detection will give the upper hand to orthodontists to engage by either prevention through extraction of deciduous canines or intercepting via assistant devices to create more space. According to the clinical situation, open or closed surgical uncovering might be required to bond an attachment. However, generally, those techniques did not show any significant clinical distinction in the outcome assessments. Clinical significance: These approaches are highly technique sensitive and require collaborations with other specialties. Proper diagnosis and prognosis assessment are necessary before making any decision to bring an impacted canine in alignment.

“…[51] Forced-eruption time can be significantly reduced using ostectomy-decortication [ Figure 6]. For a detailed description of the ostectomy-decortication technique see Wilcko et al [52] and Ferguson et al [53] In a study with 118 patients, 57 treated with ostectomy-decortication and 61 with open-closed surgical exposure, forced-eruption time was on average 6.6 months for the ostectomy-decortication group and 21.0 months for the open-closed surgical exposure group. [53] Forced-eruption time is the time between surgery date and date the canine which was tied into the orthodontic arch wire in a position similar to the adjacent teeth.…”

The prevalence of impacted maxillary canines is 2–3%. In Caucasian populations, it is reported to be more palatally displaced than buccally, with the opposite trend seen in Asian populations. At the ages of 9–11 years, the position of the canine germ should be diagnosed, for most children through clinical supervision. In 7–10% of children, the clinical investigation must be supplemented with radiographic investigation, in most cases with intraoral radiographs. About 50% of impacted canines cause root resorption of the adjacent teeth. To detect the severity of resorption, cone-beam computed tomography is necessary. Root resorptions on incisor roots occur most often at 11–12 years of age. Early diagnosis of ectopically positioned maxillary canines is very important. In cases with palatally displaced canines and no root resorptions, extraction of the primary canines has been found in different studies to give good results. If the permanent canine has not started to normalize its position within 12 months, orthodontic treatment must be taken in consideration. Often, this is done by surgical exposure and orthodontic traction of the canine out into the dental arch.

“…Palatally impacted canine (PIC) forced-eruption time averaged 6.6 months using the ostectomy-decortication technique compared with 21.0 months using open-closed surgical exposure techniques (i.e. 3.2 times more rapid) [30]. Fischer [31] reported six cases of bilateral PICs treated in a splitmouth design with randomly assigned surgical exposure on one side and selective alveolar decortication (without ostectomy) on the other; the treatment duration was 28-33% more rapid in the corticotomyassisted technique.…”

The objective of the current review was to evaluate the effectiveness of traditional and accelerated methods of palatally impacted canine's (PIC) traction in terms of treatment duration, velocity, periodontal, and patient-reported variables.An electronic search for randomized controlled trials (RCTs) and controlled clinical trials (CCTs) published between January 1990 and October 2021 was conducted in nine databases. Five major orthodontic journals were hand searched for additional studies. The participants were patients with unilateral or bilateral PICs who received conventional or accelerated orthodontic treatment with fixed appliances. Cochrane's risk of bias tool (RoB 2 tool) for RCTs and ROBINS-I tool for CCTs were used to assess the risk of bias. The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) guidelines were used to assess the overall quality of the evidence.Nine articles (eight RCTs and one CCT) were included in this review (371 patients). There was no clarity in most studies about the possible effect of the mechanical traction method on treatment outcomes. The treatment duration decreased (about three to six months) when the open surgical method was used with traditional techniques and the traction velocity increased significantly (about 1-1.5 mm/month) when acceleration methods were used. No significant differences were found between the conventional intervention groups, as well as between the traditional and accelerated groups, in terms of most periodontal variables (p > 0.005).No significant differences were found in the pain levels associated with traditional PICs' traction when comparing different exposure methods in the short-term follow-up (1-10 days), while contradictory results were found in the pain incidence between these methods. The relationship between the pain/discomfort levels and the type of mechanical traction method was not evaluated. According to the GRADE, the quality of evidence supporting these findings ranged from low to very low.The combination of the open surgical technique with various designs of either superelastic wires or elastic traction means can lead to a reduction in the orthodontic treatment duration of PICs. The use of direct anchorage by miniscrews to move the PICs away from the adjacent teeth roots can lead to a reduction in root resorption and shorten the treatment duration. The evidence supporting these findings ranged from low to very low. The use of different types of mechanical means for conventional PICs' traction, with the use of open or closed traction techniques, does not lead to significant differences in periodontal outcomes between intervention groups. Contradictory results exist regarding the severity of the perceived pain in relation to the surgical exposure type, and the relationship between this variable and the mechanical traction method is still unclear. The use of accelerated methods for PICs' traction can lead to an increase in the velocity of traction movement with no significant differences in periodontal outcomes ...
