Abstract
A 55-year-old female and a 81-year-old male presented with general gingival overgrowth under full-arch implant-supported fixed prostheses, with poor hygiene and fetid odor. Prostheses removal revealed extensive calculus accumulation covering the peri-implant region and prosthetic surface in addition to ulcers and nodular masses in the adjacent mucosa, compatible with fibrous hyperplasia. In the first case, the prosthesis was repositioned after scaling and surgical recontour of peri-implant gingivae in the same session. In the second case, after scaling, protection cylinders were installed on the mini-conical abutments, and the patient stayed 15 days without the prosthesis. On his return, remission of hyperplasia was observed, and surgical recontour of the peri-implant gingivae was performed before the prosthesis’s repositioning. It was observed that the nodular masses were neglected by the patients, indicating the need for proper orientation of hygiene techniques for implant-supported prosthesis wearers, as is widespread in removable total dentures.
