Final answer:

Keeping alginate impressions moist prevents distortion, ensuring accurate dental prosthetics.


Explanation:

Keeping the preliminary alginate impression moist is necessary to prevent distortion of the impression. Alginate can dehydrate, shrink, and distort, affecting the accuracy of the final model or restoration.

By maintaining moisture, the alginate impression retains its original shape and details, ensuring an accurate reproduction of the patient's oral structures.

This practice is essential in dental prosthetics to guarantee precise fittings for crowns, bridges, and other restorations.
