Site development in periodontal therapy--alveolar bone augmentation as an adjunct to endosseous implant placement.

This article reviews some of the current concepts of site development in periodontal therapy as well as hard tissue augmentation as an adjunct to endosseous implant placement. This article reviews the historical perspectives of guided bone regeneration and addresses the management and development of extraction sites, inadequate ridge widths, and sinus augmentation before implant placement. Selected cases are presented to illustrate these clinical situations. In addition, key concepts for the success of bone augmentation and implant dentistry are discussed.
