A 28-year-old patient presented at her general dentist’s office and complained about the appearance of her tooth 21. The patient had a history of trauma to this tooth. Endodontic treatment had been performed in the past and a crown placed on the tooth. A procedure to replace the old crown was performed by her dentist; however, a perforation on the middle third of the root occurred, and extraction of tooth 21 was suggested. Upon clinical and radiographic examination of the patient, who had been referred to us, replacement of tooth 21 by a dental implant appeared to be indicated.
