The famous golden stan- dard remains to be the autologous bone block4, 5 as it is not involved in any immunological concerns, and contains vital cells. However, the vitality of the graft is highly dependent on the perioperative storage of the graft.6 It is generally accepted that class IV and V, according to the Cawood and Howell classification,7 need block augmentation before implant placement. The use of osseous allograft blocks for alveolar pro- cessaugmentationisnotverywelldocumentedinthe literature. Antonio Barone et al.8 published his study in 2009 and showed a good success with the osseous allo- genic block, 24 blocks were used to augment the maxilla in 13 patients. Five blocks were used for ver- Figs. 1 & 2: Case 1: Horizontal atrophy of the alveolar process in the maxilla. Figs. 3 & 4: Allogenic bone block is fixed with two osteosynthesis screws.
