ABSTRACT
The conventional methods on making double splints in presurgery of skeletal Class III were complicated. To find an easy method for the improvement of the production of splints and simplify the making process, 17 severe skeletal Class III patients accepted bimaxillary surgery after making double splints were used. According to visual treatment objective (VTO) forecasting on the lateral cephalometric radiograph of ending presurgical orthodontics and analyzing study models, the surgical methods were designed, the mobile osteotomy bone volume was estimated and the maxillary abnormity was classified. For the patients with right midline and without adjusting their occlusion plane, use the single model method (antedisplace maxillary model twice) or double models method (antedisplace maxillary model firstly, and then retrodisplace mandibular model) to make the double splints which guided the fixtion of bimaxillary surgery through their parallel models and simple articulators. The making process of the double splints was simplified and improved, and the postsurgery effects of all patients were satisfied. Therefore, for making the double splints of skeletal Class III bimaxillary surgery, utilizing the proper method on the basis of the specific abnormal conditions of patients can simplify the production process and get twice the result with half the effort.
