Dental amalgam used by the dentist as a restorative material should meet the following criteria: (1) a reduced risk of marginal failure with a minimal risk of recurrent caries, (2) resistance to creep and corrosion, and (3) the characteristics for mixing, inserting, and polishing that are optimally duplicated. To achieve these criteria, the optimal amalgam technique includes the use of the following: Rubber dam whenever possible Conservative cavity preparations to offset the amalgam's inherent weak physical properties A high copper alloy combined with the appropriate amount of mercury for optimal plasticity and to reduce susceptibility to creep and corrosion Trituration, precondensation, and condensation methods that are consistently practiced by the dental assistant and dentist A burnishing scheme combined with a subsequent polishing method to complete the final amalgam restoration.
（1）边缘失败风险降低，继发龋风险最小；（2）抗蠕变和抗腐蚀；（3）混合、填充和抛光特性得到最佳复制。为达到这些标准，最佳的汞合金技术包括使用以下方法：尽可能使用橡皮障 进行保守的窝洞预备，以弥补汞合金固有的物理性能弱点 高铜合金与适量汞结合，以实现最佳可塑性并降低蠕变和腐蚀敏感性 牙科助理和牙医始终采用的研磨、预凝聚和凝聚方法 结合后续抛光方法的打磨方案，以完成最终的汞合金修复。
