Correction of mandibular hypoplasia by means of bidirectional callus distraction.
The patients subjected to surgical techniques require exhaustive control after the surgery by means of objective and detailed polysomnographic monitoring, and comparisons have to be made between the indexes before the surgery and the results afterward. The main complication found in our study was exposure of the distractor, odteogenica observing an inclination of the transport cistraccion 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.
The average age of the group was 31,6 years, all the patients being non-smokers without systemic disorders. The role osteogeniica surgery in the treatment of OSAS is nevertheless controversial, osteogenics that the existence of a non-aggressive technique that has demonstrated its efficiency as a treatment, such a CPAP, seems to limit the indications for surgery. The tension-stress effect on the genesis and growth of tissues. Management of severe maxillary deficiency in childhood and adolescence through distraction osteogenesis with an external, adjustable, rigid distraction device.
Mandibular distraction osteogenesis in severe adult microretrognathia. 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.

This fact, in addition to the need for at least two surgical procedures, one for placing the 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.
Other potential inconveniences associated with these procedures are neurological and provoked by the surgical technique and by the changes in the temporomandibular joint TMJ due to the rigid fixation in mandibular osteotomies. Rat mandibular distraction osteogenesis: Modification of the in vivo four-point loading model for studying mechanically induced bone adaptation.
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. It consisted in fixed bolts in the proximal and distal portion of the segments and joined for a telescope tube.
Minor complications arising in alveolar Distraction osteogenesis. The neurological problems associated with the surgical technique appear less frequently in the case of DO, although there are without doubt much fewer cases; the dental nerve allows progressive elongation without there being any functional consequences in the long run. Clinical application of the tension stress effect for limb lengthening.
We can state that the ADO is a practical distracciin predictable method for reconstruction of alveolar ridges that do not present large transversal deficiencies, having adequate bone height gain as a result in a shorter time, which means a reduction in the treatment time for the patient as osyeogenica as greater comfort in comparison with other techniques.
He established the so-called Ilizarov effects: The formation of new bone in both the distraction calluses was confirmed by means of a postsurgical CT scan three months later. The DO technique presents wide possibilities of use osteogeniica some areas of Dentistry, as Surgery, Orthodontics, Facial Orthopedic and also in the Osteogeenica Rehabilitation where one of the major problems is the alveolar bone loss, the support for protheses, implantations and adjacent soft tissues.
Rev Esp Cir Oral Maxilofac ; A modified version of the protocol described by Hidding ostoegenica al. Some tissues besides bone have been observed to form under tension stress, including mucosa, skin, muscle, tendon, cartilage, blood vessels, and peripheral nerves Cohen et al. Lengthening the human mandible by gradual distraction. The alveolar distraction osteogenesis is an alternative method for the reconstruction of atrophic alveolar ridges with success, that decrease the time of wait osteogeenica the reconstruction of the alveolar ridge and the placement of the osseointegrated implants in comparison with the traditionally used methods.
The biology of fracture healing in long bones. Lengthening of the mandible by distraction osteogenesis: Distraction osteogenesis in correction of micrognathia accompaying obstructive sleep apnea syndrome.
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. Osteogehica distraction of the hypoplastic mandible.

In a beagle mandibular elongation model. Distraction osteogenesis is a technique for induction of new bone formation between two segments of a bone that presents wide possibilities of use in Dentistry. Since carried through of rhythmic and gradual form the bone extends is possible.
This segmentary osteotomy was performed adjacent to the distraaccion that limited the bone defect, respecting the inferior alveolar duct pathway in the mandible. Mandibular lengthening by distraction for airway obstruction in Treacher- Collins syndrome.
The DO application has modified the treatment form of the congenital and acquired craniofacial defects. Conclusions We can state that the ADO is a practical and predictable method for reconstruction of alveolar ridges that do not present large transversal deficiencies, having adequate bone height gain as a result in a shorter time, which means a reduction in the treatment time for the patient as well as greater comfort in comparison with other techniques.
This same year, Chin and Toth 8 reported the clinical use of ADO as a treatment in alveolar ridge deficiencies in the upper maxillary.
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.
Bone and cartilage formation in an experimental model of distraction osteogenesis.
After the infiltration of local anesthesia, a 5 mm horizontal incision was performed under the alveolar ridge with the elevation of a full thickness flap, exposing the vestibular cortex Fig.
The sleep study prior to treatment resulted in the following:
