The animation shows the general procedure of bone augmention using the maxgraft® bonebuilder (here shown a typical atrophy in the lower jaw). The ridge is too thin for a secure implant placement, the bone defect requires both a horizontal and a vertical augmentation. The individually designed allogenic bone block enables this complex horizontal and vertical augmentation by using the latest 3D-CAD/CAM technology. After proper soft-tissue mobilization, maxgraft® bonebuilder is placed on the recipient site and due to its individual planning fits perfectly to the patient’s defect. The maxgraft® bonebuilder is fixated with flat-headed osteosynthesis screws. A slow-resorbable barrier membrane is placed above the operation site to prevent the ingrowth of soft tissue and as protection against resorption. A tension-free, saliva-proof wound closure is essential to avoid wound dehiscence. The healing time is approximately 6 months and at re-entry the screws are removed and implantation can follow. With full bony ingrowth of the block, now there is enough space to place the implants.

In clinical practice, the application of allogenic blocks has been established as a reliable alternative to autogenous bone blocks for alveolar ridge augmentation to avoid donor site morbidity and limitations in material quantity or as an alternative treatment if previous surgery has failed.
