No
The device description and performance studies focus solely on the physical and chemical properties of the impression material, with no mention of software, algorithms, or data processing.

No
The device is an impression material used to record oral tissue anatomy and is not described as providing any therapeutic effect.

No

This device is an impression material used to record oral tissue anatomy and is not described as providing a diagnosis.

No

The device description clearly states that CharmFlex is an "impression material" and describes various physical forms (Putty, Regular, Light, Heavy, Bite) made of "dental addition silicone impression material." It details the physical properties and packaging of these materials, which are tangible substances used to take physical impressions of oral anatomy. There is no mention of software as a component or the primary function of the device.

Based on the provided information, this device is not an In Vitro Diagnostic (IVD).

Here's why:

  • Intended Use: The intended uses listed are for creating impressions of oral tissues, teeth, and bite registration. These are physical impressions used for dental procedures and model creation. They are not used to examine specimens derived from the human body to provide information for the diagnosis, prevention, or treatment of a disease or condition.
  • Device Description: The device is described as an impression material made of silicone. This is a physical material used to capture a mold, not a reagent or instrument used for testing biological samples.
  • Lack of IVD Characteristics: There is no mention of analyzing biological samples, detecting analytes, or providing diagnostic information based on testing bodily fluids or tissues.
  • Anatomical Site: While the anatomical site is the oral cavity, the device is used to create a physical impression of the structures within the oral cavity, not to test the tissues themselves for diagnostic purposes.

Therefore, CharmFlex is a dental impression material used for physical molding, not an IVD.
