Demineralized bone matrix
Demineralized Bone Matrix (DBM)
Demineralized Bone Matrix (pronunciation: de-min-er-al-ized bone ma-trix) is a type of allograft that is used in orthopedic procedures to assist in bone repair. It is derived from the cancellous bone and cortical bone of donors, which is then processed to remove the mineral content and leave behind the organic matrix.
Etymology
The term "Demineralized Bone Matrix" is derived from the process it undergoes. "Demineralized" refers to the removal of minerals, "Bone" refers to the tissue from which it is derived, and "Matrix" refers to the intercellular substance of a tissue, or the tissue from which a structure develops.
Usage
DBM is used in a variety of orthopedic, spinal, and dental procedures. It is often combined with the patient's own bone marrow to enhance its osteoinductive properties. It is also used in bone grafting procedures as a scaffold for new bone growth.
