GUIDED BONE REGENERATION Guided Bone Regeneration (GBR) is a surgical technique that enables us to repair bone defects by creating a greater volume of bone in areas where there is some bone deformity or defect following a dental extraction. The objective of Bone Regeneration is to create the appropriate support for the placement of dental implants. The process of Bone Regeneration begins with osteogenesis, which stimulates the formation of new bone-forming cells from the bone graft. The placement of a membrane or mesh serves as a barrier at the site of the bone defect to protect and stimulate the growth of new bone. The barrier membrane prevents non-bone cells from invading the area, allowing bone cells to regenerate the lost bone. New bone will form in approximately 4 to 6 months after the bone graft. WHAT MATERIALS DO WE USE FOR GUIDED BONE REGENERATION? Depending on the origin of the biomaterial to be used, we can classify it into three groups: AUTOLOGOUS GRAFT This is when bone from the patient's own body is used. ALLOGRAFT In this type of graft, the bone comes from another person, so we are dealing with a graft that will be genetically different. In most of these cases, the graft comes from donors who may belong to blood and tissue banks. XENOGRAFT This type of bone graft comes from another animal species (usually bovine) and contains all the minerals of a human bone.
