Background: The placement of dental implant in the edentulous posterior maxilla often present difficulties as a result of insufficient bone due to pneumatization of the maxillary sinus and bone resorption after extraction. Lateral window Technique is usually accomplished by creating lateral bony window and elevation the sinus membrane. The new compartment created between the floor of maxillary sinus and the elevated membrane was filled either with autograft, bone graft substitutes or combination of them to maintain space for new bone formation. Recently, non grafting sinus floor augmentation was established based on the concept of membrane elevation and its support either by implants insertion (tenting Technique) or space maintaining devices (titanium screws or Mesh) have proven new bone formation both experimentally and clinically . Aim: Evaluate the predictability of new bone formation at sinus floor after elevation of the membrane using a space maintaining mesh without graft material
