Management of Peri-Implantitis with PRF as a Sole Grafting Material: A Case Report

Abstract

PRF was used as a sole grafting material for surgically treatment of a 8 mm pocket around an implant that had 3 threads of bone loss, BoP, and exudate, and the patient was followed up for 1 year. Surgical treatment with the help of PRF, home care reinforcement, clinical indices records, and radiographic examination was done. The patient was monitored frequently for the first 3 months. Subsequently, maintenance visits were scheduled at 3 month intervals. The patient had a decreased probing pocket depth and a negative BoP index compared to initial clinical data, and the results were stable after a year. After 1 year of follow up visit, there appeared to be rebound of the bone level radiographically.

Biomimetic Implant Surface Functionalization with Liquid L-PRF Products: In Vitro Study

“…In these patients, osseointegration is negatively affected as a result of the hypocellular, hypovascular, and hypoxic tissue environment [ 33 ], with an increased risk of failure particularly in the maxilla and in grafted sites [ 34 ]. These products could also prove beneficial in immediate implant placement after extraction, to stimulate fibrin clot formation in the gap between the alveolar bone and the implant surface, in guided bone regeneration procedures with simultaneous implant placement [ 35 ], and in the regeneration of peri-implant defects [ 36 ]. However, rather than as hitherto described in the literature, this study proposes use of liquid L-PRF instead of clots in order to enhance direct contact of the fibrin layer with the implant surface, obtaining an immediate biofunctionalization of the surface.…”
