Finite Element Analysis (FEA) and 3D modeling are two powerful computational tools that have been widely used to study the human mandible. Both methods have been applied to understand the mechanical behavior of the jaw bone, and to support clinical decision making in areas such as surgical planning, orthodontic treatment, and implant placement. In a typical FEA study, a 3D model of the human mandible is first created from medical imaging data such as CT or MRI scans. The model is then divided into small elements, or finite elements, that are connected at nodes. These elements represent the underlying structure and properties of the bone, such as its material properties and geometric shape. The finite element model is then subjected to various loads and boundary conditions, such as chewing or biting forces, to study the behavior of the mandible under different conditions. In addition to FEA, 3D modeling of the human mandible can be used to create virtual representations of the bone that can be manipulated and visualized in different ways. This can be useful for a variety of applications, such as surgical planning, orthodontic treatment, and implant placement. For example, 3D models can be used to evaluate the fit of implant components, simulate the effects of orthodontic treatment on the jaw, or assess the outcomes of various surgical procedures. In conclusion, the combination of FEA and 3D modeling provides a powerful tool for studying the human mandible and supporting clinical decision making in various fields. The ability to create virtual representations of the jaw and simulate its behavior under different conditions offers valuable insights into the biomechanics and behavior of this complex structure.
