For investigating the stresses in the reconstructed tooth and its surrounding periodontal ligament and gingiva, the authors had applied a plane-strain finite-element analysis. Applications of the proposed analysis were made for study of maximum stresses in the reconstructed tooth and in the periodontal ligament due to diminishing bone support and on initiation of occlusal traumatism. In previous analyses, only the supporting bone was assumed as rigid, finite element partitioning was carried out in (a) the reconstructed tooth region including porcelain crown, dentin, gutta percha, gold post, crown substructure, and zinc phosphate cement, (b) periodontal ligament and (c) gingiva. The authors propose a new method for investigation of the periodontal ligament stresses and demonstrate that the obtained results enable to draw similar conclusions as provided by the previously elaborated, but more time-consuming method.
