In this present paper, we introduce the beneficial use of Indonesian activated natural zeolite, precisely from Malang area, for a potential restorative material after combined with alumina and glass ionomer cement. The activated zeolite was previously impregnated by copper (II) chloride prior to prepare the composites of impregnated-activated-zeolite/alumina/glassionomer-cement composites. The X-ray fluorescence (XRF) test results support the X-ray diffraction (XRD) data in revealing the crystalline phase contents. The composites comprise of mordenite, sanidine, quartz, orthoferrosilite, and tolbachite. Scanning electron microscopy (SEM) photographs dictate the uniform CuCl2 impregnation to the activated zeolite. The CuCl2 impregnation, moreover the addition of alumina crystalline powder and GIC polymer, increase the density of activated zeolite. Finally, the impregnated-activated-zeolite/alumina/glassionomer-cement composites exhibit acceptable mechanical and antibacterial characteristics for dental restorative implants. © Published under licence by IOP Publishing Ltd.
