PROPERTIES AND PERFORMANCE OF GOLD IN DENTAL PROSTHETICS

Gold is one of the most appreciated materials used in dental prosthetics due to its outstanding properties, such as corrosion resistance, malleability, ductility and biocompatibility. This review looks at the role of gold in dentistry, highlighting its advantages and limitations compared to other materials. The physical and chemical properties of gold, such as chemical stability and malleability, allow for precise and durable dental restorations. Mechanical properties, such as wear resistance and controlled flexibility, contribute to the reliability of restorations, ensuring optimal performance in the oral environment. The biocompatibility of gold is a crucial aspect, as it is chemically inert and well tolerated by oral tissues, reducing the risk of allergic or inflammatory reactions. However, its high costs and limited aesthetics in visible areas can pose barriers to its widespread use. Gold remains a reference material in modern dentistry, being ideal for restorations in the posterior areas or for cases where durability and reliability are priorities. The future of research could explore advanced alloys and digital technologies to optimize the use of this noble material in dental prosthetics.
