Mechanical behavior of endodontically restored canine teeth: Effects of ferrule, post material and shape

Abstract

The FE analysis confirmed a beneficial ferrule effect with the combination of ferrule and quartz fiber post, with tapered shape, affording no critical stress concentrations within the restored system.

Modal analysis for implant stability assessment: Sensitivity of this methodology for different implant designs

“…Numerical models like those developed here and in previous work [27][28][29][30][31][32] can provide a useful tool to understand experimental results and to optimize the measurement protocol. These models can be further improved by simulating bone maturation.…”

“…Modern CAD-FEM (Computer Aided Design and Finite Element Method) methodologies have been extensively used in biomedical investigations to characterize biomechanical responses in dental applications [27][28][29][30][31][32].…”

CAD-FEA modeling and analysis of different full crown monolithic restorations

“…The materials and structures properties were attributed to each solid component with isotropic, homogeneous and linearly elastic behavior. Young's modulus and Poisson's ratio were reported (Table 1) [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28][29] and all contacts were ideally cast.…”

“…Load application (600 N) occurred similar to the methodology by Ausielo et al [16] which considered the contact between food bolus and tooth surface during the closing phase of the chewing cycle ( Fig. 2).…”

“…In order to evaluate the stress distribution generated by masticatory loads in the restored teeth, finite element analysis (FEA) has been used due to specimen standardization, low cost, and because it is a numerical method that offers a means to find an approximate solution [16,[30][31][32]. Some terms are very common when this computational method is used such as stress and stress concentration.…”
