铸造金合许多研究评价了牙科铸造合金的不同性质和操作程序。Whitlock等设计的铸造网试验已成为可铸造性能的常规试验。但该方法作为标准试验应用受到Naylor等的挑战。该作者采用具有斜面肩台和槽形抛光衬里的全冠代型,报告了五种合金的可铸造性以及网和冠的模型方法。该文的重要性在于先证明了两项试验结果的差异.从两项试验中获得的百分率有实质性区别。与冠模制作比较,网试验易于使用,这可能导致网试验的连续应用,但是,通过新的评估方法明显证实这种设计受到限制。
Casting Alloy Many studies have evaluated the different properties and operating procedures of dental cast alloys. Casting net tests such as those designed by Whitlock have become routine tests of castability. However, this method is challenged by Naylor et al. As a standard test application. The author used a full-crown cast with a beveled shoulder and a grooved polish lining to report castability of five alloys and a mesh and crown model approach. The importance of this article is to prove the difference between the two test results, and the percentages obtained from the two tests are essentially different. The ease of use of the net test in comparison to the production of the crown die may lead to continuous application of the net test, but the new evaluation method clearly demonstrates that this design is limited.
