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.
