简要总结
Clinical and radiographic evaluation of a new modification of ring technique using omputeraided design/computer-aided manufacturing (CAD/CAM) milling of allogeneic bone block for anterior maxilla ridge augmentation with immediate implantation
详细描述
Dental implant failure remains a clinically significant challenge, with early failures typically attributed to insufficient osseointegration, surgical trauma, bacterial contamination, or micromotion during healing. In contrast, late failures are often associated with occlusal overload, peri-implantitis, or implant mispositioning.
These challenges have driven the adoption of allogeneic bone blocks, particularly those fabricated using computeraided design/computer-aided manufacturing (CAD/CAM) technology, which offer precise anatomical adaptation, reduced surgical time, and minimized complications compared to manual grafting techniques
