RESUMO

The aim of this study was to evaluate clinical, radiographic and subjectively the alveolar distraction osteogenesis technique (ADO) in the reconstruction of atrophy alveolar ridges. Fifty-five patients were submitted to the alveolar reconstruction with distraction osteogenesis, using a extra-alveolar distractor - 51% were operated in the posterior mandible area; 40% in the anterior maxilla; 5% in the anterior mandible region and 4% in the posterior maxilla. The mean real bone gain for each region was 4,49mm ; 7,46 mm; 6,09 mm and 6,32 mm respectively, with a mean of 6,09 mm. Complications presented during the treatment were minor in 14 patients (25,45%), and major complications in 6 patients (10,90%). Patients who were treated with this technique evaluates the perception of trans and postoperative events. The results showed that 80% thought the surgery is bearable, as well as in the postoperative period (84%), they didn t feel pain during the activations (88%) only pressure sensation (58%), and they didn t present difficulty in the activation of the apparel (74%). However 22% of the patients answered that the activation stem was uncomfortable or highly uncomfortable, interfering in some oral functions. 78% of patients would undergo the surgery again and that when compared with other reconstruction methods as bone graft for instance 80% of the patients referred that this was considerably more uncomfortable. The technique of ADO demonstrated to be effective in reconstruction of atrophic alveolar ridges with a success rate of 89,09%, with minor complications that can be solved with an opportune attendance by the professional. To weigh of being a technique relatively traumatic, it has a high acceptance among the patients submitted to it, however some details as the interference of the activation stem continue inconveniencing the patient. It fits to highlight that when compared with the bone grafts the acceptance is very larger.
