Abstract

Some of the physical characteristics of two glass polyalkenoate cements have been measured. The two cements differ in terms of the presentation of the poly(alkenoic) acid used to form the cement and in the method of mixing of the materials. The 'conventional' cement uses an aqueous solution of poly(acid) and is an encapsulated mechanically mixed material. The alternative material contains a vacuum-dried poly(acid) powder with the ion-leachable glass, and is mixed by hand with a 15 per cent aqueous solution of tartaric acid. There were some minor differences between the two products, including a delay in the onset of the setting reaction for the material containing the vacuum-dried poly(acid) powder. These differences would probably have little significant effect upon the clinical performance of the materials.

摘要

已对两种玻璃聚羧酸盐粘固剂的一些物理特性进行了测量。这两种粘固剂在用于形成粘固剂的聚（烯酸）的呈现形式以及材料的混合方法方面有所不同。“传统”粘固剂使用聚（酸）的水溶液，是一种封装的机械混合材料。另一种材料包含真空干燥的聚（酸）粉末和可离子浸出的玻璃，并与15%的酒石酸水溶液手工混合。这两种产品之间存在一些细微差异，包括含有真空干燥聚（酸）粉末的材料凝固反应开始时间延迟。这些差异可能对材料的临床性能影响不大。
