Aim : The aim of present study was to evaluate BMAC/bovine graft utilization in Sinus membrane augmentation on bone height gain and quality of bone on histological assessment.~Methodology: sixteen patients suffering from atrophic posterior maxilla with sinus pneumatization were randomly divided into two equal groups: study group: the sinus membrane was elevated with bone marrow aspirate concentrate loaded on bovine graft whereas the control group recieved bovine graft only for sinus floor augmentation.~All patients will be evaluated at 1 week, 4 months by CBCT to measure bone height and bone core biopsy for histological assessment at 4 months during implant placement.
