Abstract. The problem of root fracture in case of prosthetically restored non-vital teeth is a common concern among clinicians. These fractures are caused by increasing the diameter of the root canal during the endodontic retreatment and occure on the dental arches in both the anterior and posterior area. Such treatment failures lead to extraction, therefore the physician’s goal is to limit as much as possible their occurrence. We used finite element analysis method to find out what type of corono-radicular restoration is more appropriate in order to avoid fractures. We selected two of the most commun posts used in our country: metallic NiCr casted RCR (corono-radicular reconstruction) and prefabricated fiberglass endodontic posts of various diameters and we analyzed the existing tensions in the dental structures that would predispose the root to fracture.

The purpose of this study was to determinate , using the Finite Element Analysis Method, the mechanical stress in a solid body , temporary molar restored with the self-curing GC material. The originality of our study consisted in using an accurate structural model and applying a concentrated force and a uniformly distributed pressure. Molar structure was meshed in a Solid Type 45 and the output data were obtained using the ANSYS software. The practical predictions can be made about the behavior of different restorations materials.

With the continuous development of urban construction projects in HebeiProvince, the rise and development of high-rise buildings and undergroundengineering, the design and research of foundation pit support structure has become more and more important. The design of the foundation pit support structure directly affects the settlement and position changes of the building itself and the surrounding stratum. In this paper, the characteristics of foundation pit support are analyzed, and the related theories of finite element analysis method are introduced. Combined with the actual situation of Hebei Province, the finite element analysis method is used to simulate the construction method of foundation pile anchor support structure system. The design was analyzed and studied.
