[The establishment of 3D-FE model libraries for the elements of FPD].
OBJECTIVE
To establish the 3D-FE model libraries for the elements of the FPD.


METHODS
Based on the 3-D geometric model libraries of the normal stomatognathic system, using the software, such as Powershape,Pro/E and Ansys5.5, the models of abutments,retainers and pontics were created according to the models of natural crowns. The models of connectors were established according to the sutures between the crowns.


RESULTS
This study has established the FE model libraries for the elements of the FPD, including the retainers,pontics,and connectors, three kinds of libraries and 82 elements in all.


CONCLUSIONS
The established models have a satisfied geometric configuration; the analysis models can be easily established and edited.
