Alveolar ridge preservation using a bioactive glass particulate graft in extraction site defects

This article describes the application of a bioactive glass particulate graft and placement of an expanded polytetrafluoroethylene barrier into extraction sites to preserve the residual ridge and to develop the site prior to fixed prosthetic replacement. Extraction site development can enhance and facilitate the position and shape of the pontics while maximizing the natural contour of the soft tissues.
