Inlay wax patterns should be invested as soon as possible to decrease distortion caused by?

Melting
Evaporation
Release of internal stress
Chemical reaction

The correct answer is: Release of internal stress

Inlay wax patterns should be invested as soon as possible to decrease distortion caused by the release of internal stress. The other options, such as melting, evaporation, and chemical reaction, may affect the wax pattern in some way but they are not the main cause of distortion. Internal stress, on the other hand, can cause the wax pattern to bend or warp, making it difficult to create an accurate cast or restoration. Therefore, it is important to invest the wax pattern as soon as possible to minimize the risk of distortion.
