[Combined sinus lift procedure and lateral augmentation. A treatment concept for the surgical and prosthodontic rehabilitation of the extremely atrophic maxilla].
OBJECTIVE
This paper describes a surgical and prosthetic procedure for treating the extremely atrophic maxilla. It explains a two-staged surgical technique, donor and recipient site morbidity, implant survival, and the implant-retained prosthetic rehabilitation of the patients.


METHODS
A total of 57 consecutive patients were treated with a sinus lifting procedure and a simultaneous lateral augmentation using autogenous corticocancellous block and particulate bone grafts from the iliac crest. After a 6-month bone healing period, a total of 284 endosteal Titanium screw implants were inserted. Following a 3-month osseointegration period, the implants were exposed and loaded with either fixed or removable prostheses.


RESULTS
In three cases a partial bone graft loss was observed; however, enosseous implantation was possible as planned. During the observation period none of the 284 implants was lost; 3 implants exhibited treatable peri-implant infection. Complications at the donor and recipient sites were minimal and did not negatively influence the overall clinical result of the treatment.


CONCLUSIONS
The combination of sinus lift procedure and lateral augmentation for the treatment of the extremely atrophied maxilla proved to be a safe method that produces good and reliable clinical results.
