What is the clinical advantage of the extended storage alginates?

The clinical advantage is the ability to send impressions made with extended storage alginates to dental labs. Be sure to seal the impression in a bag with 100% humidity. Extended storage alginates [Alginmax (Major USA); Hydrogum5 (Zhermack); Kromopan 100 (Kromopan USA)] are currently being used by orthodontists to scan and fabricate indirect bonding stints. With this product, the dentist does not need to pour the impression before sending it to the dental laboratory for the scanning process.
