dc.description.abstract | Distraction osteogenesis (DO) is a biologic process that generates new bone between surfaces of bone segments, which are gradually separated by traction forces. It is a uniquely effective method with multiple applications in the craniofacial region. This concept has been the basis of all bone-lengthening operations; it involved an osteotomy of the shortened bone and an external/internal fixator device, which slowly elongates the bone to its new dimension while a bony callus is being formed at the side to distraction. The biology of DO is similar to callus fracture healing. The bony regenerate passes through the same phases: formation of a collagen fibril template, mineralization, bony union and finally remodeling. The mechanisms by which the mechanical stresses applied to the bone tissue cause the cells to proliferate and form new bone are not well understood. More studies are needed to understand the cellular events underlying DO and the effects of the strains applied during DO on cellular proliferation and mineral apposition. | |
