The advantages of air vents in the production of extensive cast gold inlays and partial crowns were examined in an in vitro study aimed at reducing the occurrence of open margins in the proximal surfaces. The results of this study with a total of 44 casts showed that a closer marginal fit is achieved by the use of additional air vents.
在一项旨在减少近端表面开放边缘发生率的体外研究中，对在制作大面积铸造金嵌体和部分冠时使用通气孔的优点进行了研究。这项共有44个铸件的研究结果表明，使用额外的通气孔可实现更紧密的边缘贴合。
