The combined crown used since many years in the Prosthetic Laboratory, Institute of Stomatology, Medical Academy in Gdańsk contains an occlusal rest basis of a cast crown (the metal part is of a gold alloy or chromium-nickel steel, with veneer of acrylateor Colorstat) provides, owing to a special preparation of the abutment tooth and laboratory procedure, full stabilization of the crown, protection of parodontium and good maintenance of the veneer which plays a cosmetic role in this type of crown. The combined crowns with occlusal rest are particularly suitable for supporting bridgeworks. They may be applied onto devitalized or live teeth since they require less extensive grinding of teeth.
多年来，格但斯克医学院口腔医学研究所修复实验室一直使用的组合冠，其包含铸造冠的牙合支托基座（金属部分为金合金或铬镍钢，有丙烯酸酯或Colorstat贴面），由于基牙的特殊预备和实验室操作流程，能实现冠的完全稳定，保护牙周组织，并能很好地维护在这类冠中起美容作用的贴面。带有牙合支托的组合冠特别适合用于支撑桥体修复。它们可应用于失活牙或活牙，因为它们对牙齿的磨除要求较低。
