An obstructive apnea and a hypopnea were registered with an AHI of 0. The influence of the rate and frequency of distraction.

Development of a device for the delivery of agents to bone during distraction osteogenesis. They are also described, respectively, as distraction epiphysiolysis fast traction: Int J Oral Maxillofac Surg ; 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.

In spite of its extended use, there are few clinical reports in the literature that report the use of ADO by means of juxtaosseous devices as well as its possible complications and risks. The DO application has modified the treatment form of the congenital and acquired craniofacial defects. The tension-stress effect on the genesis and growth of tissues.

Ilizarov showed that the fibrous matrix in the prolongated area is capable to differentiate by itself in lamellar bone tissue. In spite of being a method capable of offering success in regards to the increase in height of the alveolar ridge as well as an increase in the soft tissue level, the ADO is not a substitute for autogeneous bone graft in those cases in which there is deficiency in regards to ridge thickness, it being possible to perform combined procedures of ADO and posterior placement of the autogeneous graft.

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. Distraction osteogenesis in correction of micrognathia accompaying obstructive sleep apnea syndrome. A singular aspect of the distraction technique is the fact of regeneration be followed by a simultaneous expansion of soft tissues, including vases, nerves, muscles, skin, mucosa, fascia, ligaments, cartilage and periosteum.

In clinical alveolar distraction studies, some authors attempted to approach this frequency by applying more than 1 distraction procedure per day, distributing the daily amount of distraction between 2 sessions of 0. Patient selection is essential.

In craniofacial bones, a week phase is recommended for children and a week phase for adults, although the appearance of bone with identical characteristics to those of the initial bone may take more than a year Cohen et al. Skeletal distraction of the hypoplastic mandible.

Rat mandibular distraction osteogenesis: Management of severe mandibular retrognathia in the adult patient using distraction osteogenesis. With the technology and the materials used for the construction and manufacture of odontologics equipments and instruments advanced, more delicate distractor were done.

The use of alloplastic materials does not offer us an ideal bed for rehabilitation with osseointegrated implants. Distraction osteogenesis; Alveolar ridge augmentation; Estability; Osseointegrated implants; Bone owteogenica.

A farewell to major osteotomies. DO have been used successfully in the surgeries of increase bone rim with diverse purposes.

Lengthening of the mandible by distraction osteogenesis: Differences in mandibular distraction osteogenesis after corticotomy and osteotomy. The use of ADO in the reconstruction of atrophic alveolar ridges has been shown to be a method that offers increased alveolar ridge height with bone and soft tissue gain, adapting the ridge for posterior rehabilitation of the patient by means of implants, it being a predictable method with low rates of bone absorption, in comparison with the use of bone grafts or alloplastic materials.

However, the available information on this subject is still scarce.

The main complication found in our study was exposure of the distractor, not observing an inclination of the transport segment toward the lingual one, product of the muscular and soft tissue tension, this being the main complication reported in studies in which intraosseous type distractor was used.

Plast Reconstr 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.

Applications for mandibular regrowth. After distraction, atrophy of the epithelium was observed, with the disappearance 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 the distraction vector.


Latency phase is the period between performance of osteotomy and start of the traction, during which soft callus is formed. Int J Oral Maxillofac Surg ; Alveolar distraction osteogenesis ADO is a recently introduced method, based on the principles described by Ilizarov, 4,5 who has received the credit for having defined and established the biological bases for the clinical use of osteogenic distraction in the management of different bone deformities.

The DO technique presents wide possibilities of use in some osteogenics of Oseogenica, as Distravcion, 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.

The formation of new bone in both the distraction calluses was confirmed by means of a postsurgical CT scan three months later.

Distraction osteogenesis of the mandible with a modified intraoral appliance: Ostegenica to 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.

This adaption process of adjacent soft tissues provoked by tensions generated for the distraction forces is also known as histogenic distraction.

With the use of force vectors is possible to get a significant and steady bone remodel, in varied directions, without extensive surgical interventions Mehrara et al. Multidimensional intraoral distraction osteogenesis of the mandible 4 years of clinical experience. Conclusions Surgical treatment of adults with OSAS should be established for certain patients possessing the right disrtaccion from these we will be able to select a candidate for treatment by means of DO; more experience is still required given ossteogenica the number of patients treated with this technique is still scarce.
