Stress distribution in a free-end saddle overlay denture retained by various types of metal root caps was analyzed using a two-dimensional finite element method (FEM). The analyzed model was a hemi-mandible with only a canine remaining, and sectioned into 13, 113 elements. The dynamic characteristic of a magnetic attachment was also analyzed in the same way on a model with 18, 000 elements. The analysis was to elucidate the basic functions of the magnetic attachment which had not been analyzed yet.<BR>1. The number of elements is very important in the FEM analysis, because the results are affected significantly by the number of elements.<BR>2. The height of the root cap has a significant effect on the stress distribution of the denture.<BR>3. The steepness of the lateral face of the root cap also has a slight effect on the stress distribution.<BR>4. The location of load showed the most notable influence on the stress distribution in tissues.<BR>5. By application of a magnetic attachment such as a denture retainer, the abutment tooth will not deliver an excessive load.
