Impacted maxillary canines: A clinical perspective

Abstract

As impacted permanent maxillary canine occurs in 1-2% of the population, the clinician should know th e signs and symptoms of this condition and the interceptive treatment. Features of palatal canine impaction include lack of canine bulges in the buccal sulcus indicating a lingual eruption path and possible impaction; lack of symmetry between the exfoliation and eruption of canine that may indicate palatal or lingual impaction; and abnormal mesio-distal location and angulation of the developing maxillary permanent canine on radiographs. Diagnosis of impacted canine teeth at age 8-10 years can significantly reduce serious ramifications, including surgical exposure and orthodontic alignment as well as root resorption of the lateral incisors. In specific cases, extraction of the primary maxillary canine can prevent impaction of the permanent maxillary canine and additional sequelae. This article discusses the etiology, diagnosis, and clinical management of impacted maxillary canine teeth.
