Which material is specifically designed to flow into and around tooth details for a final impression?

Light body impression material is designed to provide excellent detail reproduction and is specifically formulated to flow into and around the intricate features of a tooth. Its lower viscosity allows it to capture fine nuances and details in the oral cavity, which is crucial for accurate impressions. This property makes it ideal for creating a definitive impression that can be used for prosthetic work, crowns, or restorations.

The other materials serve different purposes; for example, heavy body impression material is used primarily to provide a bulk of material to support the lighter body during impression taking, while tray material refers to the thicker materials that are usually used in conjunction with lighter materials to ensure stability and adequate support within the tray. Elastomeric materials, although they can include various types, do not specifically denote a material that flows into tooth details as effectively as light body materials do in a clinical context. Therefore, light body impression material is the most suitable choice for capturing detailed impressions.
