Summary
A lack of bone in the posterior maxilla, mainly resulting from the combination of alveolar
bone resorption after tooth loss, pneumatization of the maxillary sinus, and periodontal
disease, leads to increased difficulty during dental implant treatment.
The classic technique for maxillary sinus floor augmentation entails the preparation of the
trap door to elevate the schneiderian membrane in the lateral sinus wall. it can be done
either in a single stage with simultaneous implant placement or in two stages with delayed
implant placement, depending on the available residual alveolar ridge height that necessary
for implant primary stability.
The new compartment created between the floor of maxillary sinus and the elevated membrane
was filled with either autogenous, allografts, xenograft or combination of them to maintain
space for new bone formation. The disadvantages of such methods are high costs for grafting
material, time consuming and high morbidity, because harvesting of bone grafts is needed.
