Abstract
Stability nof surgical counter-clockwise rotation of the mandible. One of the possible approaches to surgical treatment of anterior open-bite is the counter-clockwise rotation of the mandible or the whole maxillo-facial complex.
The aim of this study was to evaluate stability of sagittal osteotomy of the mandiblar ramus and counter-clockwise rotation of the occlusal plane and find out whether the stability of CCW rotation is affected by the number of miniplates of rigid osteosynthesis in the mandible. Our samplecomprised 26 patients who underwent CCW rotation of both upper and lower jaw.
A total of 8 cephalometric parameters were compared in 3 time periods - after the orthodontic decompesation of the anomaly (TO), maximum 7 days after surgical treatment (T1), and at least 1 year after surgery (T2). Evalution of results leads us to the conclusion that the stability of CCW rotation of the mandible is not affected by the number of miniplates used.
