Comparative Study of the Biomechanical Behavior of the Deciduous Molar-restorative Material-bone Assembly

AbstractA medical problem of great importance is the treatment of dental caries at children. If this treatment is efficient, the teeth vitality is preserved and a normal function of the dental maxillary assembly is carried out. Therefore, the purpose of this study, performed with the finite element method, was to determine the stress and strain distributions in bone structure – primary molar – restorative material assembly, and also to evaluate the contact pressure at the interfaces bone – molar and molar – restorative material when a load of 120N has been applied over all the upper surface area of model. Finally, the results for two dental fillings often used by practitioners were compared. The method used for obtaining the 3D models consisted in processing with special software (Mimics) the tomography images acquired with the aid of a CT scanner
