This clinical report describes the management of chronic, proliferative inflammatory epithelial and fibrous hyperplasia following loss of a mandibular implant-retained prosthesis. A classic surgical technique was used. The patient was referred to the oral surgeon for sialodochoplasty and sulcoplasty. With a combination of surgery and prosthodontic management with a conforming surgical stent, a satisfactory denture foundation was created, allowing for fabrication of an implant-retained definitive prosthesis.
