In cases when bone length and width is not sufficient for implant treatment the following treatments are possible
Sinus lift basically means lifting the maxillary sinus membrane through a surgical operation by pushing it upwards and the gap created is filled with bone graft material. It is performed either as open or closed lifting. In case, there is a bone structure of 4-5 mm in the implant area, closed lifting is preferred while with the bone structure less than 4 mm, open surgery is performed.
External Sinus Lift is performed when patients have extremely resorbed upper jawbone. Sinus membrane is pushed upwards by opening a window from the cheek side of patients’ upper jaw. The gap is filled with bone grafts. 4-6 months of waiting time is necessary for bone graft to augment the bones there with new bone tissue.
