Distraction Osteogenesis of the Facial Skeleton. William H. The book highlights the application of distraction osteogenesis in repositioning of teeth. The paradigm in orthognathic surgery has shifted in a way that it is now possible to perform distraction osteogenesis in an outpatient basis. The principles and procedures involved in this cutting edge technique are outlined in the book.

Musculoskeletal Tissue Regeneration pp Cite as. Distraction osteogenesis of the facial skeleton has provided both a powerful tool to those who are interested in studying the biology of bone and has added a powerful technique to the armamentarium of surgeons who treat facial disfi gurement. The application of bone distraction to the facial skeleton has been largely derived from prior work in the lower extremity, and the fundamental biologic concepts of distraction osteogenesis must be thoroughly understood before the extension of this work to the facial skeleton can be consistently applied successfully. Bone distraction initiates a complex biologic process that induces biosynthetic pathways to form additional soft tissue and bone. The application of this principle to the facial skeleton must also take into consideration specifi c characteristics of the face and its anatomy. Surgeons traditionally view the face in three separate domains: 1 the upper face — from the eyes to the top of the head, 2 the mid-face — from the upper teeth to the eyes, and 3 the lower face — from the lower teeth to the neck. Each of these three domains of the facial skeleton has its specifi c biological requirements and constraints, and each domain requires different considerations for fi xation of bone devices and for the design of linkage systems.
Innovative Surgical Sciences
In the field of orthopedic surgery, distraction osteogenesis DO is well known for limb lengthening procedures or secondary corrective surgery in the fracture treatment of the extremities. The principle of gradual expansion of bone and surrounding soft tissues as originally described by G. Ilizarov is also applicable to the craniofacial skeleton when growth deficiency is present, and the patients affected by craniofacial or dentofacial anomalies may require distraction procedures. The surgical management is comparable. Subsequently, distractors are locked to provide appropriate stability within the distraction zone for callus mineralization during the consolidation phase of 3—6 months, which is followed by a further remodeling of the bony regenerate.
Bell, a prime mover in oral and maxillofacial surgery, collected contributions from visionaries and pioneers in the field making an impact on oral and craniomaxillofacial surgery around the globe. The focus of the text is the treatment of patients with dentofacial and craniomaxillofacial deformities, which cannot be corrected by immediate repositioning of the facial bones. The work of the international contributors is described in extensive photographs and medical illustrations. Video Materials on DVD
