Aberrant Impaction of Mandibular Canine and Lateral Incisor: a Case Report

Impaction of mandibular permanent lateral incisor and canine is rare in dental practice, and its treatment is challenging because of their importance to facial esthetics and function. Aim: This case report presents a rare deep impaction of permanent lateral incisor and canine with ectopic orientation of the teeth. Material and Method: A 47 years old Saudi lady has been referred from her orthodontist to our Oral and Maxillofacial surgery clinic for consultation regarding the impacted mandibular right lateral incisor and canine. Investigations included cone beam computed tomography which showed that the right mandibular canine (#43) is impacted and the root is fully formed with dilacerations of the tip of the root, the crown is directed mesially. The right mandibular lateral incisor (#42) impacted lingual to impacted tooth #43 and the crown is directed distally below the apices of first and second premolar. Incidental finding of a unilocular radiolucency in the lower anterior area below the crown of impacted tooth #43. The treatment plan included surgical removal for future implant insertion while the orthodontic treatment was unapplicable in this case. Results: Patient undergoes surgical removal of the impacted teeth and enucleation of the associated cyst under general anesthesia. Conclusion: Mandibular canine and lateral incisor impaction is a rare condition. Its treatment options are variable including no intervention, orthodontic and surgical removal. The selection of the treatment option is highly dependent on the patient interest and need and weighting them against the possible risks.
