Osteogenic Potential of Schneiderian Membrane

In the study group: 2.0 mm screws were fixed to the lateral wall of the sinus above the superior osteotomy and placed buccopalatally where the schneiderian membrane was elevated and maintained. this technique will suspends the membrane in position to allow the blood clot to organized and formation of bone.

ll Patients in this group underwent open sinus procedures to lift the sinus membrane followed by application of the xenograft as an augmentation material xenograft is used instead of autogenous bone graft to avoid the morbidity of the donor side
