In the final diagnosis the presence of OSAS was ruled out and the patient currently does not require any treatment. Treatment of obstructive Sleep apnea syndrome by mandibular elongation using osseous distraction followed by a le fort I advancement osteotomy: Rev Esp Cir Oral Maxilofac ; Mechanical stimulation of osteoblasts in cell culture.
A modified version of the protocol described by Hidding et al. They are also described, respectively, as distraction epiphysiolysis fast traction: At 2 weeks of consolidation, the mucosa began to show a more normal appearance: Three 3 of the defects were located in the anterior region of the maxillary, 1 defect in the anterior region of the mandible and 6 in the posterior region.
Three modes of ossification during distraction osteogenesis in the rat. After, the placement of the distractor and its adaptation to the bone surface was performed Fig. Time distrafcion usually applied range from 0 to 7 days and coincide with osyeogenica 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.
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.
Distraction osteogenesis of the human craniofacial skeleton: Biomechanics of mandibular distractor orientation: Later, after a period of consolidation, there seems to be greater cell proliferation in the basal layer. Plast Reconstr Surg ; Initial outcome of vertical distraction osteogenesis of the atrophic alveolar ridge. 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: In addition, it offers a shorter waiting time between the initial stage and the placement of the implants 10 weeks in comparison with the 6 months that must usually pass for rehabilitation with implants when autogeneous bone grafts are used.
A problematic case with tongue aplasia. Results The average bone gain in millimeters achieved in the 10 cases was 7. 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.
Mandibular lengthening by distraction for airway obstruction in Treacher- Collins syndrome. II Molecular analysis of transforming growth factor beta-1 and osteocalcin gene expression. Surgical maxillofacial treatment of obstructive sleep apnea. Later on 10 weeks like part of the period of bony consolidation were awaited and osteogenicx carries out the placement of the osseointegraded implants and the retirement of the distraction device, xistraccion able to check clinic and radiographic the gain of the height and necessary bony volume for dlstraccion rehabilitation by means of implants.
Management of severe mandibular retrognathia in the adult patient using distraction osteogenesis. Mechanically induced tissue response during distraction. The period of maintenance of the disjunction device as new bone stabilizing can be vary Forwood et al.
Distracción osteogénica mandibular en microrretrognatia severa del adulto
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.
The aim of this article is to revise the literature related to bone formation, mechanically induced by Osteogenic Distraction, in order to supply subsidies for this process. Following a consolidation period of four months, the distractors were removed by means of the same approach, and in the same surgical act a reduction mentoplasty with advancement was performed, all under general anesthesia. 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.
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. The role of surgery in the treatment of OSAS is nevertheless controversial, given 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.
Other authors had followed this idea, but it was only in the decade of the 50’s that Ilizarov a, b promoted the extend bone by distraction osteogenesis having consistent and previsible results.

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. The effects of the distraction vector, the distrator stabilization and the distraction intensity and frequency of the bone corn are variable that have been examined in some studies Kessler et al.
The role of distraction osteogenesis in the reconstruction of the mandible in unilateral craniofacial microsomia. Extra and intra bucal devices have been developed and used for this intention. Correction of mandibular hypoplasia by means of bidirectional callus distraction.
As adults are involved, not all of them will be able to accept the additional orthodontic treatment and the final occlusion is thus made much more difficult. The aim of this article is to review the literature related to bone formation, mechanically induced by distraction osteogenesis, in order to supply subsidies the agreement osteofenica this process.
