Augmentation procedures for deficient edentulous ridges, using onlay autologous grafts: an update.

The purpose of this review was to analyze publications related to augmentation procedures using autologous onlay grafts and to evaluate the survival/success rates of implants placed in the augmented areas. An automated search was made in Medline, of clinical publications from 2002 to 2007, including at least 5 patients and with a minimum follow-up of 6 months. Ten papers were included. These suggested that grafts are indicated when the height of the alveolar crest is less than 5mm, or the width less than 4mm. The surface resorption of grafts protected by guided bone regeneration membranes was less than for unprotected grafts. Calvarial grafts suffered less resorption than did iliac grafts. …
