Br J Oral Maxillofac Surg ; Multidimensional intraoral distraction osteogenesis of the mandible 4 years of clinical experience. Thus, the periosteum and endosteum osteogenesis capacity are related to the formation of a new bone matrix in parallel columns to the extend axis Querido, 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: Montalvo Moreno 4 1 Medico residente.
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.
The concept of callotasis is of interest in implant surgery, especially monofocal callotasis for the linear regeneration of tissues.

The formation of new bone in both the distraction calluses was confirmed by means of a postsurgical CT scan three months later. A modified version of the protocol described by Hidding et al. 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.
After, the placement of the distractor and its adaptation to the bone surface was performed Fig. Skeletal distraction of the hypoplastic mandible.
Distracción Osteogénica en la Odontología
Conjunctive papillae began to appear, the epithelial thickness increased, and the cells recovered a normal osteoegnica, although the inflammatory distraccipn and low thickness of the horny layer persisted.
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.
A farewell to major osteotomies.
The principles of the Ilizarov method. Modification of the in vivo four-point loading model for studying mechanically induced bone adaptation. 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.
What should your therapeutic option be? Rev Esp Cir Oral Maxilofac ; Histomorphometry of distraction osteogenesis in a caprine tibial lengthening model.
A third horizontal osteotomy was performed apical to the two horizontal cuts, obtaining the transport segment. 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. Minor complications arising in alveolar Distraction osteogenesis.
Then there was a 10 week wait for the reabsorption of the distractor Fig. The influence of stability of fixation and soft-tissue preservation. The patient currently has the correct occlusion and the sleep study carried out after the surgical correction using the same team and under the same conditions revealed the following data: The sleep study prior to treatment resulted in the following: 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.
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. Gradual traction of distracciin tissues creates stress that activates tissue growth and regeneration law of tension-stress ; and the shape and mass of the bone are influenced by the mechanical load and blood supply.
Mechanical stimulation of osteoblasts in cell culture. The use of alloplastic materials does not offer us an ideal bed for rehabilitation with osseointegrated implants.

Patient selection is essential. In some cases, in order to avoid this, directing osteogejica advancement by means of directional bands will be necessary. Recently Ukan et al.
Ilizarova russian orthopedics doctor, started his perfectioning and applied the DO technique in the superior and inferior endochondral bones members for more than 35 distracion. Distraction osteogenesis in dentistry. 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 osteogejica 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.
The ADO is a method that allows us to augment alveolar ridge height with new bone formation 3,9,12 as well as distraccoon obtain a significant increase of the surrounding soft tissues, offering a predictable result, 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.
