Orthodontic management of impacted maxillary canines

Abstract

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.

Modified Cantilever System (MCS) for Early Distalization of Palatally Impacted Canine in an Adult—A Case Report

“…Distalizing the canine away from the incisor root at the earliest is recommended. 10 Age is another determinant for the prognosis of treatment involving the traction of impacted canine into the arch. This case is being highlighted owing to its extremely good outcome despite the presence of 2 factors that could have undermined its prognosis viz: age and a periodontally compromised lateral incisor.…”

Tratamiento interceptivo de los caninos impactados. Revisión de literatura.

“…Stabryta cita a varios investigadores como Ericson y Kurol, Bacetti et al, quienes reportan que entre el 65% y 78% de los casos de exodoncias de dientes temporales presentaron erupción espontánea del permanente (Stabryła et al, 2021). Bjerklin et al mencionan que la extracción del canino temporal tiene una mayor tasa de éxito cuando está en el sector 2 o 3 y el ángulo alfa está entre 20° y 30°, (Bjerklin, 2020) además se indica que la exodoncia es exitosa cuando es realizada en la etapa prepubereral (Sharma et al, 2021).…”

Cone beam computed tomography indications for interdisciplinary therapy planning of impacted canines

“…Maxillary canines that are embedded in the alveolus, unable to erupt at an appropriate time in the dental arch are considered impacted. 10 The prevalence of impacted maxillary canines is approximately 2%, but varies amongst different ethnicities. 11,12 Studies on orthodontic patients have shown that this condition appears more frequently in females.…”
