Abstract:

BACKGROUND: Artificial teeth computer aided design and computer aided manufacture (CAD/CAM) is a high technology involving various subjects. Many CAD/CAM systems have designed. However, they have some disavantages and a high cost. Therefore, only the system with proprietary intellectual property can solve this problem. 
OBJECTIVE: To optimize the connector of the CAD/CAM fixed bridge.
METHODS: Three-dimensional finite element models of the connector were established which was used to design different styles of connectors. Stress under different vertical loading conditions was compared.
RESULTS AND CONCLUSION: The connectors with different appearances displayed varying stress. Stress on the connector with arc transition was less than connector without arc transition. Connector was supposed to design to style with arc transition.
