Sinus bone grafting, also known as sinus lift or sinus augmentation, is a surgical procedure performed to increase the amount of bone in the upper jaw (maxilla) in the area of the molars and premolars. It is often necessary when there is insufficient bone height or density in this region due to factors such as tooth loss, periodontal disease, or natural anatomy.
The maxillary sinuses are air-filled spaces located above the upper jawbone and below the eye sockets. When teeth are lost in the back of the upper jaw, the sinus cavity can expand, causing the remaining bone to become too thin to support dental implants. Sinus bone grafting aims to create a solid foundation for dental implant placement by raising the sinus floor and adding bone to the area.
During a sinus bone grafting procedure, the sinus membrane is gently lifted and a bone graft material is placed into the space. The type of graft material depends on various factors, including the patient's individual needs and sinus anatomy. The bone graft material stimulates new bone growth and creates a stable and sufficient bone volume for the placement of dental implants. A sinus lift, via lateral window or osteotome, may either be completed prior to or at the time of dental implant placement.
Sinus bone grafting is a specialized procedure that requires expertise and experience. It is typically performed by periodontists who have advanced training in implant dentistry. The success of the procedure depends on factors such as the patient's overall health and proper post-operative care. It is important that you follow the post-operative instructions provided by your periodontist and return for periodic healing checks.
