sinus lift
Pronunciation: SY-nus lift
Surgical procedure to increase bone height in the posterior maxilla by elevating the maxillary sinus membrane and placing bone graft material.
Full Definition
A sinus lift, also known as sinus augmentation, is a surgical procedure performed to increase the amount of bone in the posterior maxilla in preparation for dental implant placement. The procedure involves accessing the maxillary sinus either through a lateral window approach or a transcrestal (osteotome) technique, elevating the Schneiderian membrane, and placing bone graft material in the created space. This procedure is necessary when insufficient bone height exists due to natural sinus pneumatization or bone resorption following tooth loss.
Usage
Usage note: Also called sinus augmentation; specify the surgical approach (lateral or transcrestal) for clarity.
