It would be desirable to regenerate bone vertically in a predictable way; such a technique would allow for more favorable implant - crown ratio and better esthetics for implant placement. Traditionally, several techniques has been proposed for this purpose including GBR with particulated bone and block bone graft using mandible or illium however, the efficacy of these techniques has not been firmly established because they have some week points or complications each other that it is difficult to draw firm conclusion for superiority. In recent years, We have treated 11-cases of vertical deficiency of alveolar bone using thin block and chip bone graft technique and the postoperative results showed good prognosis with few complications. So we report the results of its treatment and cases with review of literature.
