Abstract
|
|
|
|
Various methods have been introduced to augment the resorbed alveolar bone including guided bone regeneration, ridge splitting and autogenous block bone graft. Among these methods, the autogenous block bone graft has been the method of choice in unprotected area, subject to compressive forces like mastication. By using this method, a predictable amount of horizontal and vertical augmentation on the narrow alveolar ridge could be gained. Therefore, it has been considered as the golden standard for ridge augmentation. There are several intraoral sources of autogenous bone grafts such as symphysis, ramus, torus and maxillary tuberosity. Among them, maxillary tuberosity which consists mainly of a thin cortical layer and abundant marrow space has been used as a donor site for particulate bone, however there is lack of information on the use of block bone graft. This study presented a block bone graft obtained from maxillary tuberosity that could be used to correct the severely resorbed alveolar bone prior to implantation over 3 years.
