Seven 7 days after the placement of the device, the reabsorption of the suture was performed and the patient was instructed on how to perform the activation of the distractor by means of an activation key, following a pattern of 3 daily activations, corresponding to a complete circle of the key each circle 0,33 mmthe distraction rate being 0,99 mm daily, until the device activation limit was reached.
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. These last ones, although to be more steady and malleable, made it difficult for the patients for being discomforted.
Mandibular lengthening by distraction for airway obstruction in Treacher- Collins 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.
Mandibular distraction lengthening in the severely hypoplastic mandible: The period of maintenance of the disjunction device as new bone stabilizing can be vary Forwood et al. Distraction implants a new possibility for augmentative treatment of the edentulous. The techniques traditionally used in patients who present alveolar ridge atrophy in order to achieve adequate bone height for osseointegrated distrcacion placement are mainly based on the use of autogeneous bone grafts1 as well as the use of alloplastic materials.
Minor complications arising in alveolar Distraction osteogenesis. They are also described, respectively, as distraction epiphysiolysis fast traction: Motives have to be evaluated, and certain cases have to be excluded such as those with morbid obesity, or those with severe associated pathologies, while low CPAP tolerance cases didtraccion those with a severe maxillofacial deformity that would clearly benefit from treatment entailing corrective surgery should be included.
The concept of osteotomies was established in the century XIX when Malgaine described the concept of the external vistraccion in the treatment of patelares composed breakings McCarthy et al. It consisted in fixed bolts in the proximal and distal portion of the segments and joined for a telescope tube.

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.
J Craniofac Surg ;5: 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.
Introduction of an intraoral bone-lengthening device. 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 role of distraction osteogenesis in the reconstruction of the mandible in unilateral craniofacial microsomia.
Review of five cases. Surgical treatment of adults with OSAS should be established for certain patients possessing the right characteristics; from these we will be able to select a candidate for treatment by means of DO; more experience is still required given that the number of patients treated with this technique is still scarce. After, the placement of the distractor and its adaptation to the bone surface was performed Fig. Ilizarov a described 2 basic types of distraction: What should your therapeutic option be?
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.
All the patients were assisted of form ambulatory, under local anesthesia and conscientious sedation, beginning the activation from the device 7 days later to the installation, with a pattern of activation 1 mm diary until reaching the wanted bony height. The DO application has modified the treatment form of the congenital and acquired craniofacial defects. Chin M, Toth B. The influence of stability of fixation and soft tissue preservation. Surgically assisted rapid orthodontic lengthening of the maxilla in primates–a pilot study.
Distracción Osteogénica en la Odontología
Distraction osteogenesis in correction of micrognathia accompaying obstructive sleep apnea syndrome. However, in disttraccion case that concerns us there was one great disadvantage in that the mandibular advancement required for solving the OSAS was more than 10 mm, while the maximum limit for mandibular advancement by means of bilateral sagittal osteotomies is 10 mm; in addition the risk of relapse is greater, the greater the advancement required due to the distravcion exerted by the soft tissue attached to the mandible.
This fact, in addition to the need for at least two surgical procedures, one for placing oeteogenica distractor and another for removing it, and the treatment that is long, and which entails four months and greater cost, should lead us to chose correctly those cases we are to treat.
Expression of bone morphogenetic proteins during mandibular distraction osteogenesis.
