The impacted canine--an orthodontic perspective

The impacted canine is relatively common in incidence and can often lead to difficult treatment planning decisions. Cone Beam Computed Tomography (CBCT) imaging has improved diagnosis and treatment planning of impacted canines. In particular, this technology has allowed the clinician to accurately locate and visualize these teeth better than ever before, as well as greater appreciate the degree of damage to neighbouring teeth such as lateral incisors. Improved diagnosis and treatment planning with CBCT has therefore resulted in improved treatment outcomes. The objective of this presentation will be to cover the incidence, complications and management of impacted canines from an orthodontic perspective. Impacted canines are commonly cited as occurring in 1% of the population. Complications of impacted canines include root resorption and devitalization of the adjacent lateral incisor, ankylosis, cyst formation and prolonged retention of the deciduous canine. Interceptive management of impacted canines may include the removal of the deciduous canine. Managementof impacted canines also include either their removal or orthodontic movement into their correct position.
