ABSTRACT
Thanks to modern technologies we are able to choose from three different methods of creating parts for metal dentures namely casting, milling and sintering. Each one has different characteristics and advantages. Casting can be performed without expensive equipment, but its final effect considerably depends on the skill of the dental technician and issues related to the way the metal changes its state. Milling, on the other hand, requires specialist equipment, changing of cutter heads, since the accuracy of work depends on their wear and tear. Moreover, the milling process uses up more material than is needed for the particular element. Additional side effect is contamination with metal dust. Like milling, sintering also requires specialist equipment, may prove to be the optimal method: it is highly material effective and makes it possible to fabricate more than one element at the same time. The aim of the study is to present and evaluate the currently available methods of creating metal parts for fixed restorations and removable dentures. The focus was on how the method affects the metal (microscopic structure, tensile strength, yield strength, compressive stress), but also the quality of the metal-ceramic interface and the marginal seal.
