Selecting the Perfect Amalgam: Spherical vs Admix Alloys Explained (Lecture 1)

This video examines the evolution and characteristics of dental amalgams, highlighting the transition from outdated low-copper mixtures to modern high-copper alloys. While older formulas suffered from significant corrosion, current high-copper versions provide superior durability and better seal the space between the tooth and the filling. Dentists choose between admixed or spherical particles based on the required pressure and the complexity of the restoration. Despite their strength, these materials are brittle and require specific thickness and angles to prevent fractures under the pressure of chewing. Because metal conducts heat, the source emphasizes using protective liners to prevent patient sensitivity to temperature changes. Finally, although mercury-free alternatives have been researched, they have not yet successfully replaced traditional high-copper amalgam in standard clinical use.
