In the maxillary posterior edentulous region, alveolar bone resorption and increased pneumatization of the sinus cavity reduce the amount of bone available to maintain an implant-supported prosthesis. This problem can be overcome by grafting of the maxillary sinus floor to provide a sufficient quantity of bone. The application of autologous platelet-derived growth factors to shorten the time required for postgrafting bone maturation and osseointegration has been reported, but their activity was immediate and short acting. Platelet-rich fibrin, an autologous concentrate of fibrin matrix as well as cytokines and growth factors that is slowly released over time, has the potential to promote and accelerate bone regeneration. This presentation will include discussion of a completed study of 20 patients who required sinus augmentation with simultaneous implant placement and presented initial bone height of 1 to 4 mm. The only grafting material used was platelet-rich fibrin concentrate. Histologic and radiographic assessments 6 months after the grafting procedure were used to analyze the efficacy of the concentrate as sole filling material during sinus lift. In addition, the presentation will emphasize innovative, minimally invasive techniques for sinus augmentation using a balloon elevation procedure that is potentially an alternative to open sinus elevation.
