Impressions shipped to a lab should be sealed in what type of container?

Impressions shipped to a lab should be sealed in an impervious container to ensure they remain protected from contamination, moisture, and any physical damage during transit. An impervious container is designed to be waterproof and resistant to the penetration of bacteria or other harmful substances. This is vital in dental practices, where maintaining hygiene and the integrity of the impression is crucial for accurate results in further procedures, such as creating dental prosthetics or orthodontic appliances.

Using an impervious container effectively minimizes the risk of contamination, which is a key concern in dental labs. It ensures that the impressions arrive at the lab clean and suitable for processing, complying with the standards set forth by health regulations. In contrast, other container types, like a plastic bag, cardboard box, or metal container, may not provide the same level of protection against external factors that could compromise the quality of the impression.
