The influence of the rate and frequency of distraction. The technician resources of the distraction osteogenesis application proportionate benefits that represent an applicable reality in some areas of dentistry. Review of five cases. Universidade Estadual de Campinas. 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.

Mechanically induced tissue response during distraction. J Oral Maxillofac Surg ; In the distraction process, there are 3 fundamental sequential phases in which different biologic phenomena are produced. Forty obstructive apneas were detected and 94 hypopneas.

Evaluation of distraction implants for prosthetic treatment after vertical alveolar ridge distraction: Distraction osteogenesis in dentistry. Bone and cartilage formation in an experimental model of distraction osteogenesis. In the continuous DO an intramembranous bone regeneration occurs, while in the not continuous distraction process the regeneration follows a standard of chondroid ossification. They extend the ascending branch of 4 children through an extra-buccal device having between 18 and 24mm of growth.

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.

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.

Int J Oral Maxillofac Surg ; Biomechanics of mandibular distractor orientation: 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. With the technology and the materials used for the construction and manufacture of odontologics equipments and instruments advanced, more delicate distractor were done.


Allungamento graduale controllato della mandibola dopo osteotomia. Surgical maxillofacial treatment of obstructive sleep apnea. 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.

Minor complications arising in alveolar Distraction osteogenesis. Rat mandibular distraction osteogenesis: Sistraccion of distraction osteogenesis in a caprine tibial lengthening model. A singular aspect of the distraction technique is the fact of regeneration be followed by a simultaneous expansion of soft tissues, including vases, oeteogenica, muscles, skin, mucosa, fascia, ligaments, cartilage and periosteum. This technique was only spread out when Ilizarov presented his studies in a Symposium occurred in New York in the year of a, b.

Distracción Osteogénica en la Odontología

Rev Esp Cir Oral Maxilofac ; Mandibular distraction osteogenesis in the treatment of upper airway obstruction in children with craniofacial deformities.

Alveolar ridge augmentation by distraction osteogenesis. The Osteogenic Distraction is a method developed for induction of osteotenica bone formation between two segments of osteogenicw bone for a slow and gradual force of traction Campisi et al. At 2 weeks of consolidation, the mucosa began to show a more normal appearance: 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.

Two vertical and divergent osteotomies were performed by means of a circular saw with a straight piece and electric motor at 30, RPM, under constant irrigation with saline solution, including the vestibular cortex until reaching the medullary bone and were then completed by means of a Wagner straight chisel and Lucas straight chisel.

A modified version of the protocol described by Hidding et al. The DO application has modified the treatment form of the congenital and acquired craniofacial defects. The average bone gain in millimeters achieved in the 10 cases was 7.

Ditsraccion application of the tension stress effect for limb lengthening. Returning 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. Bone response to functioning implants in dog mandibular alveolar ridges augmented with distraction osteogenesis.


When segmental defects are reconstructed, bifocal or trifocal distraction is used. The concept of osteotomies was established in the century XIX when Malgaine described the concept of the external setting in the osteognica of distrafcion composed breakings McCarthy et al.

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 diwtraccion 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.

Distraction osteogenesis in adult obstructive sleep apnea surgery: InMartin Chin related be the first author to carry out DO with intra-bucal apparatus in human for alveolar process growth Feichtinger et al.

Other authors had followed this idea, but it was only ostoegenica the decade of the 50’s that Ilizarov a, b promoted the extend bone by distraction osteogenesis having consistent and previsible results. 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 DO technique can be used in the rim increase that makes possible implantations arrangement and increase diztraccion possibility to get a better cantilever outline in the anodontics areas Gaggl et al. Three modes of ossification during distraction osteogenesis in the rat.

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 or those with a severe maxillofacial deformity that would clearly benefit from treatment entailing corrective surgery should be included.

Expression of bone morphogenetic proteins during mandibular distraction osteogenesis. Distraction osteogenesis; Alveolar ridge augmentation; Estability; Osseointegrated implants; Bone atrophy.

Mandibular lengthening by distraction for airway obstruction in Treacher- Collins syndrome. Alveolar distraction osteogenesis ADO is a osteoggenica 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.
