When replacing missing back teeth in the upper jaw, some patients may find they do not have enough bone height due to the proximity of the maxillary sinuses. The sinuses are air-filled cavities located above your upper teeth. A sinus lift, or sinus augmentation, is a surgical procedure that raises the sinus floor to create space for additional bone graft material.
During the procedure, a dentist or oral surgeon carefully lifts the thin membrane lining the sinus. Bone grafting material is then inserted into the newly created space. Over several months, this material integrates with your natural bone, providing a thicker foundation. This ensures that when a dental implant is placed, it is fully surrounded by bone rather than protruding into the sinus cavity.
This procedure is often necessary because the bone in the back of the upper jaw is naturally thinner than in the lower jaw. Additionally, once teeth are lost, the sinus cavity can expand, further reducing the available bone. A sinus lift addresses these anatomical challenges, making it possible for patients to receive stable and long-lasting implants in the upper molar and premolar regions.
Recovery from a sinus lift involves specific aftercare, such as avoiding blowing your nose forcefully for a short period. Your dentist will provide instructions and may prescribe medications to prevent infection or congestion. It is important to attend all scheduled reviews to ensure the graft is healing correctly. If you experience unusual pressure or swelling, seek advice from your dental professional promptly.
