Lengthening of the mandible by distraction osteogenesis: Eur J Oral Sci ; An experimental investigation in Adult Macaca mulatta. The influence of stability of fixation and soft tissue preservation. Histomorphometry of distraction osteogenesis in a caprine tibial lengthening model. Los autores extraen una serie de conclusiones. Distraction osteogenesis of the craniofacial skeleton.
The role of chondrocytes in intramembranous and endochondral ossification during distraction osteogenesis in the rabbit. Gradual traction of the tissues creates stress that activates tissue growth and regeneration law of tension-stress ; and the shape and mass of the bone are influenced by the mechanical load and blood supply. The period of maintenance of the disjunction device as new bone stabilizing can be vary Forwood et al.
El trabajo fundamental que se refiere a este aspecto es el de Samchukov. Histologic and radiographic analysis. The effects of magnitude and frequency of distraction forces on tissue regeneration in distraction osteogenesis of the mandible. 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.
Mechanical stimulation of osteoblasts in cell culture. The effect of gradual distraction of the mandible on the sheep temporomandibular joint. It can be classified in two basic types: There has been little study of changes in the oral mucosa as a consequence of distraction. Ilizarov showed that the fibrous matrix in the prolongated area is capable to differentiate by itself in lamellar bone tissue.
The DO technique presents wide possibilities of use in some areas of Dentistry, as Surgery, Orthodontics, Facial Orthopedic and also in the Oral Rehabilitation where one of the major problems is the alveolar bone loss, the support for protheses, implantations and adjacent soft tissues.
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. Simultaneous mandibular and maxillary distraction in hemifacial microsomia in adults: Casilla D Temuco – Chile Tel.: Distraction Osteogenesis of the Craniofacial Skeleton.
Osez serial histological study. Modification of the in vivo four-point loading model for studying mechanically induced bone adaptation.
Interdental distraction osteogenesis and rapid orthodontic tooth movement: Remodeling of the temporomandibular Joint following mandibular distraction osteogenesis in the transverse dimension.
Clin Orthop Relat Res. 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 Osteogenic Distraction is a method developed for induction of new bone formation between two segments of a bone for a slow and gradual force of traction Campisi et al.
Alveolar distraction osteogenesis for dental implant preparation: Time periods usually applied range from 0 to 7 days and coincide with the initial events in the normal process of bone repair; Distraction phase is the period in which traction is applied to the transport bone fragment and the formation of new immature woven and parallel-fibered bone commences.
The concept of callotasis is of interest in implant surgery, especially monofocal callotasis for distraaccion linear regeneration of tissues. He demonstrated that distraction was also produced transversally to the longitudinal axis of the bone, which is of relevance to the distraction of the alveolar ridge. Three Dimensional Alveolar Distraction Osteogenesis. Changes in the temporomandibular joint after mandibular lengthening with different rates of distraction.
Vega LG, Bilbao A.
Distracción mandibular y articulación temporomandibular
In the continuous DO an intramembranous bone regeneration occurs, while in the not continuous distraction process the regeneration follows a standard of chondroid ossification. El primer trabajo concretamente es el de McCormick.
With respect to the frequency of distraction, he recorded better outcomes when it was performed 60 times a day compared with 1 or 4 times a day. Ilizarov had already reported that the ideal frequency of distraction is continuous. Biomechanics of mandibular distractor orientation: This article reports three cases of mandibular deformity correction in children, carried out using the distraction osteogenesis technique with resorbable devices.
J Oral Maxillofac Surg ; Bone lengthening in the craniofacial skeleton. The effects of the distraction vector, the distrator stabilization and the distraction intensity and frequency of the bone corn are variable that have been examined in some studies Kessler et al.
Clinical application of the tension stress effect for limb lengthening. Healing process after alveolar ridge distraction in sheep. The aim of this article is to revise the literature related to bone formation, mechanically induced by Osteogenic Distraction, in order to supply subsidies for this process.
Distracción ósea mandibular con aparatos reabsorbibles (reporte de tres casos).
Distraction osteogenesis for dental implants. Combined Surgical therapy of temporomandibular joint ankylosis and secondary deformity using intraoral distraction. These have been experimentally studied in bones of endochondral or intramembranous origin. J oral maxillofac Surg ; Until the present moment, the process that the mechanical forces created by the distraction osteogenesis are translated in biological signals able to induce osteogenesis in a perfectly coordinated way is still not clarified.
The distraction osteogenesis DO is a method developed for induction of new tecidual formation between two segments of a bone for a slow and gradual force of traction Ilizarov, diistraccion Ilizarov, b; Meyer et al. All patients were treated at Advanced Specialty Medical Unit UMAE 71 of the Mexican Institute of Social Security, which, for the last ten years, has been using the distraction osteogenesis method to correct mandibular deformities in children, with optimal results.
