Abstract(s)
Os caninos maxilares desempenham um papel fundamental na estética e função da arcada dentária, sendo essenciais para uma oclusão adequada e harmonia do sorriso.
No entanto, os caninos maxilares são particularmente suscetíveis à impactação, um problema comum, que ocorre quando o dente não erupciona corretamente na cavidade oral, ficando retido.
A impactação dos caninos pode ser provocada por diversos fatores, como predisposição genética, falta de espaço na arcada dentária, retenção prolongada dos dentes decíduos, alterações no trajeto de erupção ou obstáculos anatómicos. O canino superior, pela sua anatomia e trajeto de erupção mais complexo é mais propenso à impactação, comparativamente ao inferior.
O diagnóstico precoce dos caninos impactados é essencial para evitar complicações graves, como apinhamento dentário, má oclusão, ou reabsorção radicular dos dentes adjacentes. Várias ferramentas de diagnóstico, como as radiografias panorâmicas, tomografia computorizada de feixe cónico (CBCT) e avaliações clínicas detalhadas, ajudam a determinar a localização exata do dente impactado, a sua orientação
e a sua proximidade com as raízes dos dentes vizinhos.
O tratamento dos caninos impactados requer, muitas vezes, uma abordagem multidisciplinar, combinando técnicas ortodônticas com procedimentos cirúrgicos. Nos pacientes mais jovens, uma intervenção ortodôntica precoce pode levar à erupção natural do canino. Em casos mais complexos, a exposição cirúrgica do canino impactado, associada à tração ortodôntica torna-se por vezes necessária para orientar o dente até à
sua posição ideal na arcada dentária.
Esta revisão narrativa procura descrever as causas da impactação dos caninos maxilares, os métodos de diagnóstico disponíveis e as opções de tratamento, de modo a garantir uma abordagem clínica eficaz.
Maxillary canines play a fundamental role in the aesthetics and function of the dental arch, being essential for proper occlusion and smile harmony. However, maxillary canines are particularly susceptible to impaction, a common issue that occurs when the tooth fails to properly erupt into the oral cavity, becoming retained. The impaction of canines can be caused by various factors, such as genetic predisposition, lack of space in the dental arch, prolonged retention of deciduous teeth, alterations in the eruption path, or anatomical obstacles. Due to its anatomy and more complex eruption path, the upper canine is more prone to impaction compared to the lower canine. Early diagnosis of impacted canines is crucial to avoid serious complications, such as dental crowding, malocclusion, or root resorption of adjacent teeth. Several diagnostic tools, including panoramic radiographs, cone beam computed tomography (CBCT), and detailed clinical assessments, aid in determining the exact location of the impacted tooth, its orientation, and its proximity to the roots of neighboring teeth. The treatment of impacted canines often requires a multidisciplinary approach, combining orthodontic techniques with surgical procedures. In younger patients, early orthodontic intervention may facilitate the natural eruption of the canine. In more complex cases, surgical exposure of the impacted canine, combined with orthodontic traction, is sometimes necessary to guide the tooth to its ideal position in the dental arch. This narrative review aims to describe the causes of maxillary canine impaction, the available diagnostic methods, and the treatment options, in order to ensure an effective clinical approach.
