Three-dimensional finite element analysis of stress on connector of CAD/CAM fixed bridge / 中国组织工程研究

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.
