Abstract: Introduction: The process of mixing metals with non metals is called alloying, and the resulting mixture alloy. Alloys are composed of at least two elements, from which one must be metal. They are divided into alloys for fixed partial dentures-FPD (golden, golden-platinum, silver-palladium alloys, alloys for soldering and alloys for metal-ceramic dentures). Purpose: the main purpose is to investigate the longevity of fixed partial dentures-FPD in patients in relation to the basic properties of the used alloys for their fabrication. Material and methods: As material we observed 81 clinical case of patients in which was used FPD with implementation o
