Closed Surgery of Sinus Lift Bone Graft

Closed sinus lift surgery, or osteotome-mediated sinus lift, is a less invasive procedure used when only a slight increase in bone height is needed for implant placement in the upper jaw. In this approach, the sinus is accessed through the site where the dental implant will be placed, without the need to create a lateral window in the sinus wall. A small opening is made in the bone where the implant will go, and special instruments are used to gently push the sinus membrane upward, creating space for the bone graft material. Once the sinus membrane is lifted, the bone graft is carefully packed into the space beneath it. The dental implant may be placed immediately after the graft, or the area may be allowed to heal before implant placement. This technique is preferred for its reduced recovery time and lower risk of complications, making it a suitable option for patients with mild to moderate bone loss.
