Immediate Loading of the Grafted Maxillary Sinus Using Platelet Rich Plasma and Autogenous Bone: A Preliminary Study With Histologic and Histomorphometric Analysis

The preliminary results of this clinical study indicate that immediate nonfunctional loading using PRP and 50% autogenous bone combined with different substitute graft materials is a predictable protocol in the grafted maxillary sinus as early as 4 months of postgrafting. The high implant survival rate is due to the early formation of large percentages of new vital bone as confirmed by using histologic and histomorphometric analysis.
