title: [The relation between contour and stress of metal-resin interface].
abstract: The interface residual stress is closely related to the interface contour of metal-resin, which affects the service life of metal-resin restoration. The authors researched the relationship between the interface residual stress of Ni-Cr alloy-acrylic resin and the different interface contours such as the curvature, convexity, concavity, width and the angle of interface. The result showed that the stress analysis with the Laser-optical microscopic analyzer is an advanced method to study metal-resin interface stress. The interface contour of concave, shallow cavity without sharp margin is desirable for reducing the interface stress.
