Many cases of posterior edentulous maxilla have thin and qualitatively poor alveolar bone. It is often impossible to apply implant in these cases. However, the sinus lift technique may provide sufficient bone augmentation for implants.
In our clinic this sinus lift technique has been used with autogenous bone grafting since 1993. From September 1993 to September 1994, 4 sinus lifts and 8 implants were performed for 3 patients.
To evaluate this technique, these implants were checked with periodontal parameters and the sinuses were checked with CT scan.
Results: Plaque index, probing pocket depth, and probing attachment level were considered successful.
The presence of peri-implant radiolucencies were analyzed with standardized radiographs.
CT scan did not show any postoperative problems in the maxilla. CT scores of alveolar bone around the implants were about the same as that of the other side of the alveolar bone.
Three-dimensional CT scan clearly showed the resorption the bone graft.
