InMartin Chin related be the first author to carry out DO with intra-bucal apparatus in human for alveolar process growth Feichtinger et al.

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.

Mandibular distraction osteogenesis in severe adult microretrognathia. Distraccoin of distraction implants for prosthetic treatment after vertical alveolar ridge distraction: Patient selection is essential. 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. 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 osteohenica were distributed parallel to the distraction vector.

No evidence of infection or reabsorption in the alveolar ridge was observed in any of the patients seen in the post-operative periods of the first and second surgical phase. The operative lengthening of the femur. The purpose of this study is to present part of our experience in the use of ADO by means of a yuxtaosseous device developed in Brazil to increase the alveolar ridge and posterior rehabilitation by osseointegrated implants in a sample of 10 patients seen between January to Octoberevaluating the intraoperative and postoperative complications.


The DO technique presents wide possibilities of use in dixtraccion areas of Dentistry, as Surgery, 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. A review of consecutively treated surgical patients. Efect of allogenic, freeze-dried, demineralized bone matrix on guided bone regeneration in supraalveolar peri-implant defects in dogs.

Following a preoperative examination which included lateral and anteroposterior teleradiography of the skull as well as an orthopantomography and cephalometric analysis, opting for the following surgical procedure was decided upon: The ADO is a method that allows us to augment alveolar ridge height with new bone formation 3,9,12 as well as to obtain a significant increase of the surrounding soft tissues, offering a predictable osyeogenica, with low morbidity and infection rates and a significantly shorter waiting period for rehabilitation with implants 10 weeks in comparison with the traditionally used methods.

One of the important applications occurs in the extensive oral rehabilitations cases where unsatisfactory prosthetic reconstructions are frequent because of the advanced alveolar rim loss and the difficulties in recovering it with enxertia.

Distracción Osteogénica en la Odontología

Its fixation was performed by 8 mm monocortical screws and then the activation to thus determine the absence of obstacles and therefore the free displacement of the transport segment Figs. In the century XIV, Guy de Chauliac was the first one to study the continuous traction for reduction of breakings.

As treatment for this, the distraction process was halted for 12 hours, in addition to the relevant medical treatment, after which the distraction process was started at the same rate in order to reach an elongation of 19 mm. The DO technique can be used in the rim increase that makes possible implantations arrangement and increase the possibility to get a better cantilever outline in the anodontics areas Gaggl et al. Int J Oral Maxillofac Surg ; He established the so-called Ilizarov effects: J Oral Maxillofac Surg ; There is less risk of the dental nerve being damaged in this way.


The implants placed presented adequate osseointegration in every case. More recently, DO has modified the treatment form of the congenital and acquired craniofaciais defects Altuna et al.

Applications for mandibular regrowth. With the technology and the materials used for the construction and manufacture of odontologics equipments and instruments advanced, more delicate distractor were done.

However, the available information on this subject is still scarce. Montalvo Moreno 4 1 Medico residente.

In the continuous DO an intramembranous bone regeneration occurs, while in the not continuous fistraccion process the regeneration follows a standard of chondroid ossification. The biology of fracture healing in long bones.

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. 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.

Extra and intra bucal devices have been developed and used for this intention. Modification of the in vivo four-point loading model for studying mechanically induced bone adaptation. J Oral Maxillofac Surg ; Br J Oral Maxillofac Surg ; Bone and cartilage formation in an experimental model of distraction osteogenesis.

The tension-stress effect on the genesis and growth of tissues. What should your therapeutic option be? Once the distractors were fixed, these were tried in order to ensure that they functioned properly and they were put back into place before closing the incision.
