In a beagle mandibular elongation model. In addition, it offers a shorter waiting time between the initial stage and the placement of the implants 10 weeks in comparison with the 6 months that must usually pass for rehabilitation with implants when autogeneous bone grafts are used.
Travesera de Gracia,Barcelona, Barcelona, ES, maxilo elsevier. Patient selection is essential.
The operative lengthening of the femur. Efect of allogenic, freeze-dried, demineralized bone matrix on guided bone regeneration in supraalveolar peri-implant defects in dogs.
However, in the case that concerns us there was one great disadvantage in that the mandibular advancement required for xistraccion the OSAS was more than 10 mm, while the maximum limit for mandibular advancement by means of bilateral sagittal lsteogenica is 10 mm; in addition the risk of relapse is greater, the greater the advancement required due to the tension exerted by the soft tissue attached to the mandible.
Conjunctive papillae began to appear, the epithelial thickness increased, and the cells recovered a normal architecture, although the inflammatory infiltrate and low thickness of the horny layer persisted.
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.
Distraction osteogenesis of the mandible with a modified intraoral appliance: However, the DO also has its inconveniences; the main one is based on the direction of the vector of distraction, a factor that increases when two or more distractors are used simultaneously that require a parallelism to be maintained among them; 3 in the case of mandibular advancement, the tendency to develop open bite during the distraction is frequent.
Obstructive sleep apnea syndrome: The position on the bone was marked previous to the osteotomy so that the distraction vector could be maintained parallel to the occlusal plane, and so that both distractors could be kept suitably parallel to each other in order to avoid any convergence which could damage the TMJ; 1 these devices are fixed by means of unicortical screws in the distal fragment before the osteotomy and once this has been carried out with a chisel the proximal segment can be fixed.
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. Plast Reconstr Surg ; Thus, the periosteum and endosteum osteogenesis capacity are related to the formation of a new bone matrix in parallel columns to the extend axis Querido, Osteogeica 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.
Differences in mandibular distraction osteogenesis after corticotomy and osteotomy. In maxillary bones, the ossification is largely intramembranous, although foci of endochondral ossification have been reported by some authors. Minor complications arising in alveolar Distraction osteogenesis.

Rev Esp Cir Oral Maxilofac ; We present the case of a year-old male that came to our unit for an assessment of a dento-facial deformity associated with an Obstructive Sleep Apnea Syndrome OSAS ; the patient presented micro-retrognathia and an ogival palate and the response in the OSAS to CPAP treatment had been deficient.
The tension-stress effect on the osetogenica and growth of tissues. The calotasis is being used more in the distraction osteogenesis in experimental models and clinical applications because the clinical difficulties associates to the first principle epiphyseal tissues fragility for the setting of traction mechanical systems and the new bone formation inhibition because the trauma generated for these instruments.
Ilizarova russian orthopedics doctor, started his perfectioning and applied the DO technique in the superior and inferior endochondral bones members for more than 35 years. Later, after a period of consolidation, there seems to be greater cell proliferation in the basal layer. Since carried through of rhythmic and gradual form the bone osteogrnica is possible. Evaluation of distraction implants for prosthetic treatment after vertical alveolar ridge distraction: With the success, they proposed an intra-buccal distractors model for human, but it did not arrive to be used.
Initial outcome of vertical distraction osteogenesis of the atrophic alveolar ridge. The influence of the rate and frequency of distraction. The tension-stress effect on the genesis and growth of tissues: Management of severe mandibular retrognathia in the adult patient using distraction osteogenesis.

Returning distraccoin the case that concerns us, we are presented with a young man, with no associated medical pathology, who had previously tried CPAP treatment but had experienced an unsatisfactory clinical response with low tolerance and who had, in addition, severe micro-retrognathia.
Distraction implants a new possibility for augmentative treatment of the edentulous. The DO application has modified the treatment form of the congenital and acquired craniofacial defects.
