What does “Block bone graft” mean?
A block bone graft augments deficient jawbone by adapting and fixing a block-shaped graft to the area.
A different form from particulate graft material
Instead of filling with particles, a shaped block is fitted to the defect. Required width, height, and stability are considered, and screws or other devices may immobilize it. “Block” describes form and is a separate classification from origin.
Graft origin and surgical extent
The graft may be harvested from the patient’s jaw or another site, or a processed allogeneic block may be used. Autogenous harvesting also requires consideration of donor-site pain, swelling, and sensory changes. Required quantity and surrounding tissues guide material choice and surgical sequence.
Fixation and placement after healing
Graft fit, stable fixation, and soft-tissue coverage are secured and healing monitored. Resorption, wound exposure, or infection may affect the plan. After healing, actual conditions determine implant placement and management of fixation screws.
Frequently Asked Questions
Is a block graft always autogenous bone?
No. “Block” describes a solid form. Confirm separately whether the source is autogenous, allogeneic, or another type.
Can block grafting and implant placement occur on the same day?
It depends on whether stable implant fixation is possible in remaining bone and on the defect extent. Some plans first wait for graft healing.
