Sinus Grafting Using Autogenous Bone and Platelet-Rich Plasma: Histologic Outcomes in Humans

Mario Aimetti, MD, DDS/Federica Romano, DDS/Claudia Dellavia, DDS, PhD/Sergio De Paoli, MD, DDS

PMID: 19146054

Four partially edentulous patients received particulate autogenous bone and platelet-rich plasma (PRP) in one sinus and particulate autogenous bone alone in the contralateral sinus. After 6 months of healing, two or three Osseotite implants were inserted, and an additional Osseotite mini-implant was placed into the graft through the lateral wall of the sinus. At abutment connection, the mini-implants were retrieved for histologic examination. Despite similar clinical and radiographic healing patterns, a higher bone-to-implant contact rate was observed on the implants placed in bone and PRP than on those placed in bone only (46.75% ± 13.6% versus 20.5% ± 5.57%, respectively).
