Management of peripheral giant cell granuloma around complete-arch fixed implant-supported prosthesis: A case series.

Abnormal peri-implant tissue response in the form of benign reactive lesions, such as peripheral giant cell granuloma and pyogenic granuloma, is a less frequent biologic complication associated with dental implant therapy. However, these lesions can cause gingival pain, swelling, and discomfort, as well as peri-implant bone loss and possible implant failure. Few reports in the dental literature have described these lesions around complete-arch fixed implant-supported prostheses. The purpose of this clinical report was to describe 3 distinct scenarios in patients with complete-arch fixed implant-supported prostheses presenting with benign reactive lesions that were histologically diagnosed as peripheral giant cell granulomas. Each of these 3 patients had acrylic resin as one of the materials in their prosthesis. The distinctive management of each of these 3 patients encompassed surgical, prosthodontic, and pharmacologic means.
