Can a bone block graft, as a platform for a dental implant, come from other than a person's own body when the goal is to build height?

no: So any body tissue brought from another persons body will be rejected. The only acception to this is that twins can sometimes get away with it because they have the same genetic material. This bone graft would serve like a transplant and would not work. Now sometimes there are bone grafts or substitutes that have had the genetic material removed that can be used. Check with your surgeon for more.

Yes: Bone loss limits the ability to successfully place dental implants and/or partial dentures due to the absence of sufficient bony volume in the mandible or maxilla. The block allograft replaces the need for autogenous bone harvesting by providing a sterile-packaged block of corticocancellous bone for implantation. The block allograft eliminates the need for a secondary surgical procedure. See dent.

Yes: Blocks of bone from another individual are termed 'allograft blocks'. Although the bone is not as ideal as your own bone, since it's not capable of growing bone cells from itself, it can still be effective in allowing bone cells to migrate to the defect area and help eliminate the bone height defect. This type of graft can be successful, but does offer risks of less bone volume produced.

Yes: Block grafts can come from cadavers or synthetic products. But the god standard and the highest success block grafts come from your own bomne.

Yes: This type of graft is known as autogeneous graft in which bone from one self (chin area, ramus area) is removed to build up bone that is deficient in height or width or both.
