Abstract
Distraction osteogeneses (DO), also called callus distraction, callotasis, osteodistraction, and distraction histogenesis is a biological process of regenerating neoformed bone and adjacent soft tissue by gradual and controlled traction of the surgically separated bone segments. Physical and biological parameters affecting the success of DO include the macro and microscopical bone anatomy, the direction and amount of the applied distraction forces, and the regenerative capacity of the tissues involved. Force transduction via adjacent structures (joints, ligaments, muscles, and soft tissue) influences the regeneration of the tissue between the bone fragments by modulating the stress produced within the callus. The clinical applicability of DO is dependent upon device-related and tissue-related factors. Device-related factors affect the mechanical integrity of the distractor and the stability of bone fixation. The number, length, and diameter of fixation pins, the rigidity of the distractor fixation, and the material properties of the device affect the clinical result of the distraction procedure. Additionally, the orientation of the distraction device and the resulting distraction vector relative to the anatomical axis of the distracted bone segments. In case of the jaws ? the occlusal plane and the joint position are important considerations. Tissue-related factors affecting the quality of the generated distraction tissue include cross-sectional area, the density of the distracted bone segments, the length of the distraction gap, and the tension of the soft tissue envelope. In the maxillofacial skeleton, DO replacing many of the traditional surgical treatment for Congenital and acquired deformities. The Biomechanics of DO and its Clinical Implications in the maxillofacial skeleton will be discussing.
