At present, guided bone regeneration is predominantly applied in the oral cavity to support new hard tissue growth on an alveolar ridge to allow stable placement of dental implants. When bone grafting is used in conjunction with sound surgical technique, guided bone regeneration is a reliable and validated procedure.
Bone grafting is a surgical procedure that replaces missing bone in order to repair bone fractures that are extremely complex, pose a significant health risk to the patient, or fail to heal properly. Some small or acute fractures can be cured without bone grafting, but the risk is greater for large fractures like compound fractures.
Demineralized bone matrix (DBM) is allograft bone that has had the inorganic mineral removed, leaving behind the organic "collagen" matrix. It was first discovered by Marshall Urist in 1965 that the removal of the bone mineral exposes more biologically active bone morphogenetic proteins . [ 1 ]
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.

When there is inadequate bone available, bone grafting procedures and sinus lift procedures may be carried out to increase the volume of bone. Bone grafting procedures in the jaws have the disadvantage of prolonged treatment time, restriction of denture wear, morbidity of the donor surgical site and graft rejection .
The quality of the repair tissue after these "bone marrow stimulating techniques" depends on various factors including the species and age of the individual, the size and localization of the articular cartilage defect, the surgical technique, e.g., how the subchondral bone plate is treated, and the postoperative rehabilitation protocol.
An autograft reduces the risk of rejection but requires a second surgery site, adding pain, risk and possible longer aftercare. Xenograft, a transplant from another species; Isograft, a transplant from a genetically identical donor, such as an identical twin. Synthetic and metal implants. Unlike allografts, such grafts do not corporate into the ...
A Phemister graft is a type of bone graft which uses bone tissue harvested from the patient to treat slow-healing, or delayed union bone fractures. [1] Thus, it is a form of autotransplantation. Typically, the tissue used in the graft is cancellous bone harvested from the patient's Iliac crest and laid in strips across the fracture site.
