The Custom Approach for Complex Defects

Patients with severe atrophy of the mandible or maxilla who have elected for an implant-supported restoration may benefit from customized treatment. Allogenic (human) blocks as well as autologous blocks are the choice materials for the bone graft required for these cases. The success or failure of the grafting procedure may be determined by how well the block conforms to the defect.

Puros Allograft Customized Blocks are a crucial developmental step in block grafting. A custom block is produced using CAD/CAM technology based on a CBCT/CT scan of the defect area. This makes the procedure more comfortable for your patient by reducing surgery time and minimizing the risk of complications.1
