Bosworth Co. - **Product Code:** [ELW](/submissions/DE/subpart-d%E2%80%94prosthetic-devices/ELW.md) - **Decision Date:** Apr 13, 2000 - **Decision:** SESE - **Submission Type:** Traditional - **Regulation:** 21 CFR 872.3660 - **Device Class:** Class 2 - **Review Panel:** Dental ## Indications for Use Paste catalyst is used with a condensation-type silicone base paste or putty as a dental impression material to reproduce a patient's teeth and gums, and to provide models for study and for production of restorative prosthetic devices. The paste catalyst causes the base material to set. ## Device Story Activator paste functions as a chemical catalyst for condensation-type silicone dental impression materials. Used by dental professionals in clinical settings to initiate the setting reaction of base paste or putty. The resulting material captures anatomical details of teeth and gums, enabling the creation of dental study models and restorative prosthetics. The device is a chemical additive, not an electronic or software-based system. ## Clinical Evidence No clinical data provided; device relies on established chemical properties of condensation-type silicone impression materials. ## Technological Characteristics Chemical catalyst paste for condensation-type silicone impression materials. Operates via chemical cross-linking reaction to set base material. No electronic components, software, or energy sources. ## Regulatory Identification Impression material is a device composed of materials such as alginate or polysulfide intended to be placed on a preformed impression tray and used to reproduce the structure of a patient's teeth and gums. The device is intended to provide models for study and for production of restorative prosthetic devices, such as gold inlays and dentures. ## Special Controls *Classification.* Class II (Special Controls). ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
