Sinus Lift Procedure: Sinus lift procedures are used sometimes used when there is insufficient bone to place a dental implant. If the x-ray or CAT reveals that there is not enough bone height to place the implant, a bone graft may be required. If the maxillary (upper jaw) sinus is in the area where implants need to be placed, a procedure called a sinus lift may be preformed. With a sinus lift procedure, a small window of bone is formed and the delicate membrane of the sinus is pushed up. Bone can then be grafted into the area where the sinus was. Many dental surgeons prefer to use bone from the patient (an autogenous graft) to add the needed jawbone height to place implants. The grafts are usually taken from the iliac crest of the hip, a different area of the jaw, or the skull.
