Soft and hard tissue defects create an anatomically less favorable foundation for ideal implant placement. Reconstruction of the alveolar bone through a variety of regenerative surgical procedures has become predictable. It may be necessary prior to implant placement or simultaneously at the time of implant surgery, to provide a restoration with a good long term prognosis.

Discussion
A variety of onlay bone graft techniques has been used for severely resorbed ridges. The success of the reconstructive procedures is influenced by the span of the edentulous ridge and the amount of attachment on the neighboring teeth. Although, autologous onlay bone graft techniques have been considered as gold standard, for horizontal augmentation (Matsumoto et coll 2002). Donor sites ,morbidity ,associated with block grafts has turned attention to the use of allogenic graft materials. Many different techniques exist for effective bone augmentation. Further comparatives studies are warranted to evaluate the best approaches.
