Computer-assisted autogenous shell technique and simultaneous implantation for reconstruction of an atrophic alveolar ridge in the esthetic zone.

The autogenous shell technique offers strong biological performance by combining the mechanical stability of cortical bone with the rapid revascularization of particulate autograft. However, the method is highly technique-dependent, particularly when performed concurrently with implant placement, as both the bone shell and implant require spatially accurate positioning. A technique involving a fully digital protocol delivering controlled, predictable, and prosthetically guided shell grafting with simultaneous implant placement is described.
