What are ideal procedures for the use of alginate substitutes?

Alginate substitutes [AlgiNot (Kerr Corp.), 3M ESPE Position Penta Quick (3M ESPE), Silgimix (Sultan HealthCare), StatusBlue (Zenith Dental/DMG)] can be used for any procedure for which alginates are usually used. Examples of uses include pre-operative provisional impressions; impressions for diagnostic casts, night guards and bleaching trays; and duplicate impressions of existing diagnostic casts. Alginate substitutes can also be used for bite registrations. Alginate substitutes can be stored and can be poured multiple times. For example, an alginate substitute stint for an interim restoration could be saved for future use when needed to replace a broken provisional restoration.
