Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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
