Comparative stability study of wire osteosynthesis versus rigid fixation in the treatment of Class III dentoskeletal...

The study analyzed two samples of 10 patients with Class III dentoskeletal deformities and maxillary and mandibular involvement. Surgery was performed on both jaws at the same time, using different techniques for the stabilization of bone. In one group, osteosynthesis by wire fixation was performed (WF); and in the other group, bicortical screws were used for the mandible (RIF) and plates for the maxilla. At 20 and 40 days after the operation, radiocephalometric examinations were performed, and the differences in structural stability verified, by comparing the efficiency of the two methods of bone stabilization. Results indicate that in the postoperative period analyzed, dentoskeletal movements in the RIF group were inferior compared with the WF group. On the basis of these results, the advantages and the disadvantages offered by these two techniques of bone stabilization are analyzed.
