amalgamatäyte

Amalgamatäyte, commonly known as a silver filling, is a dental restorative material used to fill cavities caused by tooth decay. It is a compound made from a mixture of approximately 50% elemental mercury and 50% alloy powder, which typically contains silver, tin, copper, and sometimes zinc. The alloy powder is triturated with liquid mercury to form a malleable mass that a dentist can shape and pack into a prepared tooth cavity. Once placed, the amalgam hardens through an amalgamation process, forming a durable restoration.

The use of amalgam fillings dates back to the mid-19th century and they have been widely employed due to their longevity, cost-effectiveness, and ease of application. Amalgam restorations are known for their resistance to wear and their ability to withstand chewing forces, making them suitable for molars and premolars. While generally considered safe and effective by major dental organizations worldwide, concerns have been raised regarding the mercury content and its potential health and environmental impacts. Consequently, the use of amalgam fillings has seen a decline in many regions, with composite resin fillings becoming a more popular alternative, particularly for aesthetic reasons. However, amalgam remains a viable and recommended option in certain clinical situations and for patients where cost is a significant factor.
