Abstract

This entry explains the details of bone remodelling, including the separate activities of osteoclasts and osteoblasts, and discusses recent findings that explain how remodeling leads to mechanically adapted bone tissue, and the role of the mature bone cells or osteocytes in this process. A hypothesis is presented that relates osteocyte apoptosis resulting from disuse, to the loading-aligned tunnelling activity of osteoclasts. Last, the entry discusses how adaptive remodeling leads to unwanted bone loss, e.g., around arthroplastic implants and after tooth extraction.
