The maxillary sinuses are anatomical air-filled cavities located at the level of the roots of the posterior teeth of the upper jaw. Sinus cavities tend to sag downward due to the loss of teeth in the posterior regions of the upper jaw, the effect of gravity and respiration. The sagging and enlargement of the sinus cavities causes loss of bone volume in the posterior regions of the upper jaw and poses a problem when it comes to implant treatment due to bone deficiency.
Sinus elevation procedure is the filling and elevation of the sinus cavities that have sagged down with bone graft materials and allows implant treatment to be applied to the edentulous areas of the upper jaw with bone deficiency. This procedure ensures that sufficient bone volume is created for the length and width of the implant that needs to be placed in the bone.
