Which classification of gold alloys is often used for inlays?

The classification of gold alloys is based on their hardness and suitability for various dental applications. Type I gold alloys are classified as soft and are often used for inlays and crowns. These alloys are easy to burnish, making them ideal for creating a smoother finish and achieving a precise fit in dental restorations. They typically provide good workability, allowing dental professionals to manipulate them effectively during the crafting of inlays.

Type II alloys, while also suitable for inlays, are slightly harder than Type I. They provide a good balance of strength and workability but are more commonly used for crowns and bridges where greater durability is required. Type III and Type IV alloys are even harder and primarily used for cast crowns and bridge frameworks rather than for inlays.

Thus, Type I is the preferred choice for inlays due to its softness, which allows for better adaptation and contouring during the placement procedure, ensuring optimal results in dental restorations.
