What do resistance areas prevent in the context of dental restoration?

Resistance areas in dental restoration are specifically designed to prevent the rotation of a restoration. These areas provide the necessary mechanical retention and support to keep the restoration in place during normal function, ensuring that it remains stable and does not move or rotate when forces are applied, such as during biting or chewing.

By creating specific geometries in the preparation of the tooth, dental professionals are able to enhance the locking mechanism of the restoration, allowing it to resist functional loads. This is particularly relevant in fixed prosthodontics where stable retention is critical for the longevity and health of the dental restoration.

The other contexts mentioned, such as distortion of the waxing process, dislodging of restoration, and undercuts, have their importance but do not specifically relate to the primary function of resistance areas, which is to prevent rotational movement of the restoration.
