The book "Distraction Osteogenesis" provides a comprehensive introduction to the modern technique of distraction osteogenesis, which is applied in orthodontics and dentofacial orthopedics. This innovative method aims to regenerate new bone and soft tissue through tissue engineering by gradually moving a bone fragment after a surgical osteotomy. The use of a distraction device creates tension around the callus, promoting the formation of new bone and triggering an adaptive response. This response allows for greater bony movement, reduces the risk of relapse, and eliminates the need for autogenous grafts, thereby avoiding complications at the donor site. The book covers the origins and advancements in this field, the fundamental mechanisms of action, indications, contraindications, as well as treatment protocols for craniofacial developments.
