SPECTRA FORM™ Chromatic Alginate Impression Material is a dental impression material based on alginate. It is used for taking impressions of the oral cavity with the purpose of constructing a gypsum cast that is a copy of the situation in the mouth. It is a general purpose impression material for making study models, first impressions for the construction of individual trays, situation models, orthodontic impressions etc.

SPECTRA FORM™ Chromatic Alginate Impression Material is a color-changing alginate: it becomes violet upon contact with water in the mixing bowl, changes to pink indicating the end of the mixing time and then finally changes to off-white indicating the end of the setting time in the mouth.

This document is a 510(k) premarket notification letter from the FDA regarding an alginate impression material. It does not contain information about acceptance criteria or a study proving device performance in the context of AI or software. The letter is a regulatory document confirming substantial equivalence to a predicate device for a physical dental impression material.
