An analysis of peripheral giant cell granuloma associated with dental implant treatment

This report discusses the management of a 21-year-old male who developed a peripheral giant cell granuloma (PGCG) associated with dental implant therapy, and reviews 4 previously reported cases of PGCGs developing in association with dental implant treatment. The patient described in this report was treated with multiple dental implants to manage severe oligodontia. Six years after implant placement, with the patient lost to follow-up, he presented to his dentist complaining of increasing swelling in the right mandibular vestibule. The patient was noted to have a large exophytic, ovoid-shaped, firm, smooth-surfaced, maroon-colored lesion. The lesion was found to be a PGCG associated with a dental implant. The lesion was treated successfully by explantation of the dental implant, complete excision of the lesion, and curettage of the underlying bony defect. No evidence of recurrence was seen over 12 months of follow-up.
