Osteogenic Potential of Schneiderian Membrane

Maxillary sinus augmentation is commonly performed by creating a space below the Schneiderian membrane which is further filled using autografts, bone graft substitutes, or a combination of both to allow for new bone formation. Recently, a new method called non-grafting sinus floor augmentation has been introduced as an alternative approach. This method is based on the idea of elevating the membrane and supporting it through implant insertion or the use of space-maintaining devices like titanium screws or mesh. This study was conducted to evaluate the efficacy of new bone formation after sinus floor elevation using space maintaining resorbable pins without graft material.
