Purpose:
A new method of reconstruction of the atrophic maxilla by combining a bilateral sinus floor elevation and cancellous bone graft with buccal and labial onlay graft using L-shaped corticocancellous blocks from the posterior iliac crest is presented.
Patients And Methods:
Seventeen patients were treated with this procedure. One hundred one IMZ implants were placed in 14 patients, and 22 Brånemark implants were placed in three patients. Patients were observed for 6 months after prosthetic rehabilitation.
Results:
All patients were fully rehabilitated with fixed bridges except one, who preferred an overdenture. Only two implants were lost at the time of the abutment connection. Some bone resorption was seen around six implants. The success rate with this procedure was 92.7% 6 months after prosthetic rehabilitation if implants with bone resorption were considered failures.
Conclusions:
These preliminary results indicate that this surgical procedure is suitable for reconstruction of most atrophic maxillas.
