Sinus lift surgery, also known as maxillary sinus floor augmentation, is a dental surgical procedure performed to increase the vertical dimension of the posterior maxilla (upper jaw) by elevating the sinus membrane and grafting bone material into the subantral space. This procedure is typically indicated when there is insufficient bone height in the posterior maxilla to support dental implants. #sinuslift #sinus #dental #surgery #DentalImplants | Dental Daily
