When a patient needs a dental implant in the upper jaw but the bone at the implant site is too thin or weak, this can sometimes necessitate what is called a “sinus lift,” which carefully moves the sinus out of the way and adds a bone graft to the area. Depending on the site of the implant and the specific conditions of the case, our periodontist, Dr. Robert Ferrell, will provide one of two different types of sinus lift procedures:

Lateral Window Sinus Lift

In this procedure, the periodontist will carefully cut a small “window” into the bone of the upper jaw, exposing the outer membrane of the sinus just behind it. With precision, the membrane is detached from the outer wall of the sinus cavity and it is pushed upward. The area below the sinus is filled with bone grafts and the incision is closed up. This method is usually used when there is less than 5mm of bone at the intended implant site.

Indirect Sinus Lift

For the indirect method, a small hole is drilled in the crest of the gums at the site of the future implant almost all the way through the bone. When just a thin layer of bone is left under the sinus floor, this last layer is carefully cracked, and granulated bone (or another grafting material) is inserted through this break to gently lift up the sinus with rising bone material, which hardens and is integrated into the natural bone of the jaw. Indirect sinus lifts are recommended when there is at least 6mm of bone at the implant site.
