Abstract:   (379 Views)
The treatment of impacted maxillary permanent incisors is challenging due to its importance for facial aesthetics. This anomaly has several detrimental effects that can lead to aesthetic and dental occlusal problems. Dental impactions can be associated with various factors. The most common factors associated with impacted teeth include extra teeth, odontomas, cysts, root anomalies, deviation from the eruption pathway, retention of supernumerary deciduous teeth, genetics, bone disease, and trauma to primary teeth. In addition, the highest probability of the transposition phenomenon was observed in the upper permanent canines. Transposition of the upper permanent canines occurs in 80% of cases with the first premolar and in 20% of cases with the lateral incisor. Both general and local factors can be responsible for tooth displacement. Local factors include genetic factors as well as dental anomalies (congenital absence of lateral incisors, conically shaped lateral incisors, rotation, hypodontia), migration of the tooth buds from their natural growth path, root dilaceration, dental trauma and enamel formation disorders. Cone beam computed tomography (CBCT) is the most accurate imaging procedure for diagnosing tooth misalignment. Intraoral surgery with sequential movements of impacted and displaced teeth helps to achieve an optimal treatment result. This study reports a case of the patient in whom an impacted central incisor was radiographically detected in the late mixed dentition together with transposition of the maxillary permanent canine.
