Impacted canines are a common finding in patients seeking orthodontic treatment. The management of impacted canines usually requires cooperation between oral surgery, orthodontics and periodontology. The orthodontic approach aims in moving the corresponding tooth into its correct position in the dental arch without causing periodontal problems. Optimum periodontal support is related to initial position of the impacted tooth as well as to the type of the surgical and orthodontic technique used. Aim of this paper was to critically review the periodontal interactions in reference to the management of impacted canines and the corresponding orthodontic and surgical techniques used. It can be concluded that the periodontal condition of treating impacted canines is almost always affected not-depending from the surgical or orthodontic procedures used. However, it seems that less damaging effects on the periodontium should anticipated when using the closed-surgical exposure techniques, which involve raising of a surgical flap, bonding of an attachment and finally resuturing of the flap to its original position.
