The physical properties and bond strengths of two glass ionomer materials reinforced with silver and amalgam alloy powders were compared with those of a conventional material from the same manufacture as well as two commercially available products. The diametral tensile strength, hardness and bonding strength are improved with the addition of either commercial available silver particles or fabricated high-copper amalgam alloy powders to the glass. Simple mixture of the metal or alloy powders with the glass ionomer cement seems to be feasible to improve the properties of the regular cement. However, further studies in formulating an optimal composition of metal or alloy, setting characteristics and long-term clinical evaluation are necessary before proposing uses for this new material.
将两种用银和汞合金粉末增强的玻璃离子材料的物理性能和粘结强度，与同一制造商生产的传统材料以及两种市售产品的性能进行了比较。通过向玻璃中添加市售银颗粒或制成的高铜汞合金粉末，可提高其径向拉伸强度、硬度和粘结强度。金属或合金粉末与玻璃离子水门汀简单混合似乎可以改善普通水门汀的性能。然而，在提出这种新材料的用途之前，有必要对金属或合金的最佳成分配方、凝固特性和长期临床评估进行进一步研究。
