Bone grafts are used in hopes that the defective bone will be healed or will regrow with little to no graft rejection. [19] Besides the main use of bone grafting – dental implants – this procedure is used to fuse joints to prevent movement, repair broken bones that have bone loss, and repair broken bone that has not yet healed.

Although there has been evidence that alloplasty is a viable method for repairing and substituting defects, there are disadvantages including suitability of patient bone quality and quantity for long term implant stability, possibility of rejection of the alloplastic implant, injuring surrounding nerves, cost of procedure and long recovery times.
Artificial bone refers to bone-like material created in a laboratory that can be used in bone grafts, to replace human bone that was lost due to severe fractures, disease, etc. [1] Bone fracture, which is a complete or partial break in the bone, is a very common condition that has more than three million US cases per year.

Demineralized freeze dried bone allograft, referred to as DFDBA, is a bone graft material known for its de novo bone formation properties. [1] It is used extensively in bone grafting of alveolar bone in oral and periodontal surgery.
Microfracture surgery is an articular cartilage repair surgical technique that works by creating tiny fractures in the underlying bone. This causes new cartilage to develop from a so-called super-clot.
Another study, conducted by Baylor University, found that ACL reconstruction procedures using the bone-patella tendon-bone technique took 2.5 hours longer than using a hamstring graft. The operation room costs and hospital charges for that amount of extra time came to about $1,580 more expensive. [ 42 ]
Hair grafting involves taking skin from areas of the scalp where there’s hair and attaching (or grafting) it to bald or thinning areas. There are two types of grafts: slit grafts and micrografts.
The GBR principle was first examined by Dahlin et al. in 1988 on rats. The selective ingrowth of bone-forming cells into a bone defect region could be improved if the adjacent tissue is kept away with a membrane; this was confirmed in a study by Kostopoulos and Karring in 1994. GBR can be used for bone regeneration on exposed implant coils . [4]
