Each device is consisted of 1:1 base and catalyst component, packaged in 560mL jars for DENU Putty set and 50mL syringes for other devices.
This is a 510(k) premarket notification for a dental impression material, DENU Light Body (Regular, Fast), DENU Heavy Body (Regular, Fast), and DENU Putty Set (Regular, Fast). The submission aims to demonstrate substantial equivalence to legally marketed predicate devices.
Here's an analysis of the acceptance criteria and supporting study information:
1. Table of Acceptance Criteria and Reported Device Performance
The acceptance criteria are primarily derived from the international standard ISO 4823:2021 (Dentistry - Elastomeric impression materials) and the device's performance is compared to these standards and the predicate devices.
