One of the primary challenges faced by today’s dental restorative team is the need to deliver high-strength restorative options without compromising the esthetic outcome fueled by ever-increasing patient demands. The availability of improved ceramic materials, bonding techniques, new technology and issues of malgam safety have led to a revival of interest in ceramic inlays in dentistry over the...

objective: this in vitro study evaluated the fracture strength and bending amount of twotypes of fiber reinforced composite (frc) and cast metal frameworks used for fabrication of inlay fixed partial dentures (ifpds). materials and methods: seventy-two extracted first maxillary premolars and molars (36 each) were embedded in acrylic resin to represent a missing of second maxillary premolar. frc...

Among the existing rapid and economical sheet metal–forming technologies, stamping with a press using soft tools, especially low-melting-point alloy dies, is one of few methods that can meet precision requirements in industrial fields such as automobile manufacturing. However, usability method limited by low strength base. The current study proposes new structure zinc-based dies for metal formi...
