[Application of BEM in loaded stress analysis of rigidly fixed bridge].
Boundary Element Method(BEM) can be used successfully to the theoretical analysis of loaded stress of rigidly fixed bridge. Using BEM the numbers of dimension of the problem to be solved can be reduced by one. Compared with the Finite Element Method (FEM), BEM has the important features: less data to be input, simple data preparation, less CPU time, high efficiency, high accurate evaluation of stress etc. Besides more dense elements can be placed at selected points to be studied in order to reflect better the concentration of stress. The practice has shown that BEM is a valuable method for biomechanics analysis in prosthodontics.
