When is an autogenous block graft especially indicated?

An autogenous block graft is especially indicated for Division B ridge conversion to a Division A ridge due to its ability to provide bone that is biologically compatible with the recipient site. Autogenous grafts, harvested from the same patient, offer the best potential for osseointegration and healing because they retain the patient’s own growth factors and living cells. This is crucial in cases where there is significant bone loss or a need for augmenting the ridge to facilitate successful dental implant placement.

In the context of converting a Division B ridge, which typically lacks adequate bone width or height, an autogenous block graft can be placed to enhance the dimensions of the ridge, ultimately improving the chances of implant success. The graft provides immediate structural support and encourages new bone formation, making it a preferred choice for these specific procedures.

While other options like socket grafting, sinus grafting, and periodontal root coverage can benefit from grafting techniques, they often utilize different grafting materials or approaches rather than specifically focusing on the structural enhancement required for Division B to Division A ridge conversions.
