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.
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.
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. [4]
Socket preservation or alveolar ridge preservation is a procedure to reduce bone loss after tooth extraction. [1] [2] After tooth extraction, the jaw bone has a natural tendency to become narrow, and lose its original shape because the bone quickly resorbs, resulting in 30–60% loss in bone volume in the first six months.

A heart-lung transplant is a procedure carried out to replace both heart and lungs in a single operation. Due to a shortage of suitable donors, it is a rare procedure; only about a hundred such transplants are performed each year in the United States. [citation needed] The patient is anesthetised. When the donor organs arrive, they are checked ...
[9] [7] Rather than removal of excessive or irregular areas of labial cortex, it involves the removal of intraseptal bone and repositioning of labial cortical bone. This technique is commonly used in an area where the ridge is of relatively regular contour and adequate height but presents an undercut to the depth of the labial vestibule because ...
Articular cartilage stem cell paste grafting was initially described by Kevin R. Stone M.D., a San Francisco-based orthopedic surgeon, in 1997 .The technique was devised in response to reports that many of the contemporary cartilage restoration procedures lead to the development of fibrocartilage, not true hyaline articular cartilage.
In orthopaedic medicine, a bone graft can be sourced from a patient's own bone in order to fill space and produce an osteogenic response in a bone defect. However, due to the donor-site morbidity associated with autograft, other methods such as bone allograft and bone morphogenetic proteins and synthetic graft materials are often used as alternatives.
