Purpose: Among mechanical stress analysis methods of teeth and prosthetic appliances, finite element analysis using computer generated 3-dimensional models has been widely applied. We tested a new method to generate 3-dimensional tooth models which can be applied to finite element analysis.
Materials and Methods: Three-dimensional tooth models were generated from micro-computer tomography images using 3-dimensional graphic software and computer aided design (CAD) software, and the models were applied to finite element analysis.
Results: The models generated using this method better mimicked the anatomical structure of natural teeth than those generated by other methods. As a sample case, a 3-dimensional model of an upper first molar tooth with a class I cavity was generated using 3-dimensional CAD software. Finite element analysis was carried out using this model by assuming that the cavity was filled with three different materials.
Conclusion: The method used in the present study yielded high-quality 3-dimensional models of teeth that can easily be applied to mechanical stress analysis using finite element analysis and other dental applications.
