Using concentrated growth factors as an alternative to bone graft material in sinus augmentation to rehabilitate atrophic posterior maxilla

Abstract

A larger number of senior patients want to eliminate the use of conventional overdenture such as Conventional Complete Denture or Removable Partial Denture and replace it by an Implant-supported fixed prosthesis or at least implant-supported overdenture with the purpose of restoring and improving the masticatory function, aesthetics besides helping them gain confidence to talk and smile. Most of those patients have lost their teeth and been posteriorly edentulous for extended periods of time, causing severe bone resorption and Pneumatized Maxillary Sinus that makes it impossible for conventional dental implant placement. This report reviews two successful cases of rehabilitation of the atrophic posterior maxilla with previous bilateral ridge augmentation in Pneumatized Maxillary Sinuses using solely Concentrated Growth Factors (CGF) without bone graft augmentation with simultaneous implant placement. Where CGF is obtained from the patient's which was collected in blood collection tubes and processed by a special centrifuge device.
