Abstract

The aim of this study is to present the contemporary approach as well as the interdisciplinary management of impacted canines in the upper jaw. Impacted canines are common and frequent complain. After the third molars, the maxillary canines are the most commonly impacted permanent teeth. About one third of impacted maxillary canines are positioned labials or within the alveolus, and two thirds are located palatals. The appropriate timing and surgical procedure for uncovering an impacted canine are determined by specific criteria. Although the mechanical management of impacted teeth is a routine task for most orthodontists, certain impactions can be frustrating, and the esthetic outcome can be unpredictable if the oral surgeon uncovers the impacted tooth improperly. When referring a patient to have an impacted tooth uncovered, the orthodontist might assume incorrectly that the surgeon knows which surgical procedure to use. However, if not instructed properly, the surgeon could select an inappropriate technique, leaving the orthodontist with the difficult if not sometimes lengthy and challenging task of erupting the impacted tooth into the dental arch. On the other hand, if the correct uncovering technique is chosen, the eruption process can be simplified, resulting in a predictably stable and esthetic result. This is very important in the surgical-orthodontic treatment of impacted maxillary canines. Retention of permanent maxillary canines incurs the risk of complications, among which resorption of permanent incisors is quite frequent. Early diagnosis of resorption is difficult as in most cases it occurs posterior or anterior in the mid-root of the lateral incisor. Studies have demonstrated the necessity to take X-ray pictures not later than at the age of 10 to supplement the clinical examination whenever resorption is suspected. If in the oral cavity examination, lateral incisors exhibit atypical position, i.e. the crowns are distally protruding and deviated and canine ridge is palpable, resorption can be recognized. Completing the orthodontic part of the therapy does not mean finalization of the definitive treatment of the impacted canines. An appropriate periodontal status of the repositioned impacted tooth as well as of the nearby teeth is the only reward for the dentists for a successful oral-surgical as well as orthodontic therapy of the impacted canines.
