摘要：

背景：口腔固定修复金属材料在人体内会对机体产生一定的影响，因此选择最佳的口腔生物材料可以减少对人体的损害。
目的：分析不同口腔修复固定金属材料的生物性能，为口腔生物材料的选择提供辅助信息。
方法：研究分析各种常用口腔修复固定金属材料的生物学性能，包括摩擦学性能、细胞相容性以及耐腐蚀性能，并比较各种口腔修复固定材料的生物学性能，以明确最佳的口腔生物材料选择应用。
结果与结论：以金、钛为基质的合金材料表现出较高的生物性能，从抗摩擦性能、细胞相容性以及耐腐蚀性能均表现出较好的生物相容性，而银钯合金、钴铬合金的生物相容性与纯钛和金、钛合金相比较略低，镍铬合金的生物相容性最差，因此在进行口腔修复固定材料选择时，应选取以金、钛为基质的合金材料以及纯钛，尽量避免选择镍铬合金材料。

Abstract:

BACKGROUND: Fixed metallic dental materials have a certain effect on organism in the body. Thus, to select an optimal biomaterial can reduce the damage to human body.
OBJECTIVE: To analyze the biological properties of different fixed metallic dental materials and to provide information for selecting a suitable biological material.
METHODS: This study analyzed the biological properties of various fixed metallic dental materials, including tribological property, cell compatibility and corrosion resistance, as well as compared the biological properties of various fixed metallic dental materials to identify the optimal material.
RESULTS AND CONCLUSION: Alloy material using gold and titanium as matrix showed high biological properties and high biocompatibility from the aspects of tribological property, cell compatibility and corrosion resistance. However, the biocompatibility of silver-palladium alloy and cobalt-chromium alloy was slightly lower compared with pure titanium alloy and titanium alloy. The biocompatibility of nickel-chromium alloy was poorest. Therefore, we should select alloy material using gold and titanium as matrix and pure titanium, and try to avoid nickel-chromium alloy material.
