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.
An operation to graft the OOKP is undertaken in severe pemphigoid, chemical burns, Stevens–Johnson syndrome, trachoma, Lyell syndrome and multiple corneal graft failure. [ 4 ] There is a significant risk of anatomical failure of lamina in the long term, estimated at 19% in a small study, [ 5 ] with the main risks being laminar resorption ...
Osseointegration is also defined as: "the formation of a direct interface between an implant and bone, without intervening soft tissue". [1]An osseointegrated implant is a type of implant defined as "an endosteal implant containing pores into which osteoblasts and supporting connective tissue can migrate". [2]
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 .
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.
