title: Properties of two nickel-chromium crown-and-bridge alloys for porcelain veneering.
abstract: Composition, microstructure, mechanical properties, and alloy-porcelain bond strength of two proprietary nickel-chromium-based crown-and-bridge alloys were studied. The materials exhibited compositional as well as microstructural differences. Wiron-S was significantly stronger and harder than Microbond-NP. Microbond-NP yielded alloy-porcelain bond strength values comparable to those of precious alloy-porce-lain combinations.
