Interdental distraction osteogenesis and rapid orthodontic tooth movement: The distraction osteogenesis DO is a method developed for induction of new tecidual psea between two segments of a bone for a slow and gradual force of traction Diistraccion, a; Ilizarov, b; Meyer et al. With the success, they proposed an intra-buccal distractors model for human, but it did not arrive to be used.
The tension-stress effect on the genesis and growth of tissues. Los autores extraen una serie de conclusiones.
This abstract may be abridged. With the technology and the materials used for the construction and ,andibular of odontologics equipments and instruments advanced, more delicate distractor were done. In maxillary bones, the ossification is largely intramembranous, ristraccion foci of endochondral ossification have been reported by some authors.
Once the distraction is ended, the central fibrous and osteoid areas ossify and gradually mineralize in a largely intramembranous manner in facial bones, becoming immature bone that will form remodeling areas for transformation into mature lamella bone.
The role of chondrocytes in intramembranous and endochondral ossification during distraction osteogenesis in the rabbit. Distraction lengthening of the mandibular costochondral graft: The concept of osteotomies oosea established in the century XIX when Malgaine described the concept of the external setting in the treatment of patelares composed breakings McCarthy et al.

Br J Oral Maxillofac Surg ; This adaption process of adjacent soft oea provoked by tensions generated for the distraction forces is also known as histogenic distraction.
Distracción mandibular y articulación temporomandibular
Studies about compression, twist and shear forces application of the bone prolongated by osteogenesis distraction had been carried out. Mandibular lengthening by gradual distraction. In a beagle mandibular elongation model.
El trabajo fundamental que se soea a este aspecto es el de Samchukov. Simultaneous mandibular and maxillary distraction in hemifacial microsomia in adults: J Craniofac Surg ; It was verified that after a period of stabilization between 4 and 8 weeks, after the distraction forces application, the levels of regenerated bone compressibility and twist already met normalized, although the levels of shear strenght, exactly after 8 weeks still remain reduced.
InMartin Chin related be the first author to carry out DO with intra-bucal apparatus in human for alveolar process growth Feichtinger et al. After distraction, atrophy of the epithelium was observed, with the distracccion of papillae and the loss of intercellular connections in granular and spinous layers, the formation of dilated capillaries was increased in the lamina propria, there was a mild inflammatory infiltrate, and the collagen fibers were distributed parallel to mandibilar distraction vector.
There has been little study of changes in the oral mucosa as a consequence of distraction. Distraction osteogenesis of the craniofacial skeleton.
Mechanical stimulation of osteoblasts in cell culture. According to recent studies, reabsorption toothless alveolar rims or mandibular and maxilar atrophies caused by a syndrome can also be corrected successfully with this technique Jazrawi et al. Distraction osteogenesis; Bony formation; Dentistry. The biology of fracture healing in long bones. One of the important applications occurs in the extensive oral rehabilitations cases where unsatisfactory prosthetic reconstructions are frequent because of the advanced alveolar rim mandiublar and the difficulties in recovering it with enxertia.
This technique was only spread out when Ilizarov presented his studies in a Symposium occurred in New York in the year of a, b. Ellis E, Hinton RJ. Los pacientes con deformidades craneofaciales requieren generalmente multiples y, a veces, complejos procedimientos quirurgicos para reconstruir tejidos blandos y duros alterados.
