The development of natural aesthetics has been facilitated by various innovative ceramic materials and techniques. Although metal-ceramic restorations have traditionally been the standard for durable and predictable restorations, the use of metal core materials may result in dense, opaque restorations. The incorporation of low-fusing porcelain materials has enabled the provision of translucent restorations that enable sufficient light transmission and strength. This article presents two comparative case reports that demonstrate the clinical application of a synthetic low-fusing quartz glass-ceramic material for the fabrication of aesthetic and functional metal-ceramic restorations.
