Popis: | The most distal abutments supporting distal-extension removable partial denture are included heavy torsional stress. Therefore, the splinting of abutment teeth are used to distribute the stress among the multiple teeth. The purpose of this study is to analyze the dynamic difference between the primary splinting and the secondary splinting.Finite element method was used to analyze. Three conditions tested by loading points were the following: 1. Load on the most distal abutment, 2. Load on the artificial teeth, 3. Load on the natural and artificial teeth. The stress and the displacement of abutments and supporting tissues were calculated. The results of this analysis were followings.1. In the condition of loading on the most distal abutment, the stress concentration of this abutment on primary splinting model was larger than that on secondary splinting model.2. In the condition of loading on the only artificial teeth and on the natural and artificial teeth, the stress concentration of abutments on the primary splinting model was larger than that on secondary splinting model. |
