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

Elements: Chemical Symbols and Isotopes
Some symbols are derived from the common English name of the element; others are abbreviations of the name in another language — Latin, Greek or German. For example, the symbol for aluminum (common name)...
