Augmentation of the maxillary sinus floor and alveolar ridge for placement of endosseous implants in the edentulous maxilla

Placement of endosseous implants in the atrophic maxilla is often restricted because of lack of supporting bone limiting placement of implants of adequate length in a prosthodontically optimal position. There are several surgical procedures to create sufficient volume of bone for the placement of implants. In this paper, a technique is described for augmentation of the maxillary sinus floor and simultaneous widening of the alveolar crest with autogenous bone.
