There are many reports of tumor which occurred around dental implants, but there are few reports of the cyst. We report a case of nasopalatine duct cyst which occurred in the dental implant insertion area.
A 54-year-old female underwent immediate implant placement in the maxillary right central incisor one year before visiting our hospital. In 2007, panoramic radiograph and CT showed an oval-shaped radiolucency around the apex of the implant. By the hope of the patient, we performed only enucleation of the cyst without implant removal. Histopathological diagnosis was nasopalatine duct cyst. In 2015, panoramic radiograph and CT image showed a recurrence of the cyst. We performed enucleation of the cyst again and implant removal because of the agreement of the patient. Histopathological diagnosis was nasopalatine duct cyst. The postoperative course was uneventful. The recurrence is not seen 20 months after operation.
