Sinus lift augmentation using autogenous bone grafts and platelet-rich plasma: radiographic results.

Objectives: Autologous bone grafting and sinus floor elevation is a widely accepted method for reconstruction of the atrophic maxilla. The aim of this investigation was to examine the influence of platelet-rich plasma (PRP) on bone grafting in sinus floor augmentation.

Study Design: A prospective, controlled, randomized study including 34 patients undergoing sinus augmentation before implant placement was designed.
