2D and 3D finite element analysis of central incisor generated by computerized tomography

The mechanical properties of human dentin for 3-D finite element modeling – numerical and analytical evaluation

“…However, their geometry is relatively easier nowadays thanks to 3D scanners (micro-CT and CT), which offer an easy and fast way to build virtual geometry in any computer-aided engineering (CAE). 6,7 On the other hand, the physical description of the material and boundary conditions are often significantly simplified. Some typical FE model inputs may be simplified and/or reduced to the essential parts.…”

“…There are a few main mechanical parameters connected with the physical problems and qualities which can have a direct link to the obtained results, including dentin properties, which are usually assumed to be homogeneous, isotropic and linear elastic. [3][4][5][6][7] Expanding such a method into biomechanics requires a significant and continuous improvement of modeling techniques with respect to the individual anatomic and pathological characteristics of human tissues.…”

“…[3][4][5][6] Depending on the research topic, finite element (FE) models in macro-, meso-and microscales can be used. 3,[7][8][9] However, FE models of the biological structure are usually performed using a simplified approach. The employed method may play different roles depending on the model type, physics-related problems or the investigation's objectives.…”

Comparative analysis of the stress distribution in five anatomical types of maxillary central incisor

“…The most basic and most critical step of the three-dimensional finite element method is the accurate establishment of a finite element model, and the accuracy of the modeling will affect the accuracy of the results [6]. IAVP Poiate et al [7] compared the accuracy of the simplified two-dimensional model and three-dimensional model of the maxillary central incisor and found that their trends of stress distribution were similar but the stress values were greatly different, and the results of the two-dimensional model could not represent the anatomical structure configuration of the complex teeth. Therefore, how to obtain the high-resolution image data became the primary task of modeling.…”

Finite Element Analysis in Dental Medicine

“…The success of restorative materials depends on their properties to withstand and resist occlusal forces and successfully support the remaining oral structure [2]. Studies examining the biomechanical behavior of oral structures require sophisticated simulations of the fundaments of the stomatognathic system [3].…”
