COMPARATIVE STABILITY STUDY OF WIRE OSTEOSYNTHESIS VERSUS RIGID FIXATION IN THE TREATMENT OF CLASS-III DENTOSKELETAL DEFORMITIES

The study analyzed two samples of 10 patients with Class III dentoskel etal deformities and maxillary and mandibular involvement. Surgery was performed on both jaws at the same time, using different techniques f or the stabilization of bone. In one group, osteosynthesis by wire fix ation was performed (WF); and in the other group, bicortical screws we re used for the mandible (RIF) and plates for the maxilla. At 20 and 4 0 days after the operation, radiocephalometric examinations were perfo rmed, and the differences in structural stability verified, by compari ng the efficiency of the two methods of bone stabilization. Results in dicate that in the postoperative period analyzed, dentoskeletal moveme nts in the RIF group were inferior compared with the WF group. On the basis of these results, the advantages and the disadvantages offered b y these two techniques of bone stabilization are analyzed.
