Glass-ionomer restoratives exhibit several unique characteristics such as moisture tolerance, chemical adhesion to tooth, and fluoride release. Since their introduction some 50 years ago, these materials have continuously improved in terms of mechanical properties and setting time. However, their clinical application is typically limited to restoring non-stress-bearing areas. Clinical studies have shown that glass ionomers have lower early wear resistance, but they exhibit similar long-term wear as composite resins. Thus, the need arose for an innovative restorative system that improved early physical properties while maintaining the unique advantages of glass ionomers to allow for a wider use of the material.
玻璃离子体修复材料具有几个独特的特性，如耐湿性、对牙齿的化学黏附性和氟化物释放。自 50 年前问世以来，这些材料在机械性能和凝固时间方面不断得到改进。然而，它们的临床应用通常仅限于修复非承重区域。临床研究表明，玻璃离子体的早期耐磨性较低，但它们的长期耐磨性与复合树脂相似。因此，需要开发一种创新的修复系统，在保持玻璃离子体独特优势的同时提高早期物理性能，从而扩大材料的使用范围。
