The 510(k) summary describes a light-cured dental material for temporary restorations and does not mention any AI or ML components or functionalities.
No
The device is a temporary restoration material for dental prostheses, which is not intended for treating or diagnosing diseases, but rather for restorative purposes.
No
Explanation: The device is described as a "light cured single-component material for the temporary restoration of crowns, bridges, or similar dental prostheses." Its function is to provide a temporary restoration, not to diagnose a condition.
No
The device is a physical material (resin) packaged in a syringe, not a software program.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that Evadyne® is for the "temporary restoration of crowns, bridges, or similar dental prostheses." This is a direct treatment or restoration of a physical structure within the body (or a prosthesis replacing one).
- Device Description: The description details a material that is applied and cured to form a temporary restoration. This is a physical intervention, not a test performed on a sample taken from the body.
- Lack of Diagnostic Purpose: There is no mention of the device being used to diagnose a condition, measure a substance in a biological sample, or provide information about a patient's health status based on in vitro analysis.
IVD devices are specifically designed to be used in vitro (outside the body) to examine specimens derived from the human body (like blood, urine, tissue) to provide information for diagnostic, monitoring, or screening purposes. Evadyne® does not fit this description.

The continents are North America, South America, Europe, Africa, Asia, and Australia. The islands are Greenland, Iceland, Japan, and New Zealand. The map is a useful tool for learning about the world.
Intended Use:
Evadyne® is a light cured, single-component material for temporary restoration. Evadyne® is easily expressed through the plunger type syringe and the low viscosity paste allows for direct filling. The product is delivered directly into the prepared cavity using single-use, disposable tips. Evadyne is a tasteless, odorless restoration, provides good sealing and can be easily removed when the permanent restoration is to be placed.
The Indications for Use and Intended Use information for the predicate product are equivalent and are reproduced below:
PREDICATE DEVICE:
The legally marketed predicate for the Evadyne® Temporary Crown and Bridge Resin is Fermit-N, (K934978), a light-curing temporary filling material produced by IvoClar N.A., Inc.
Indications for Use: Temporary restoration material
Intended Use: - Temporary restorations in the inlay/onlay technique for temporary restorations of all kinds. Relining material for prefabricated temporary crowns and bridges made of polycarbonate or methacrylates.
As is documented in the comparison of Indications For Use and Intended Use, the Evadyne® temporary bridge and crown resin and the Fermit N temporary bridge and crown resin are indicated for the same use, share the same clinical indication, clinical setting, target population, anatomical sites, intended use, prescription requirement, storage conditions and method of application.
Technological characteristics - Evadyne® versus the predicate device
A technical comparison of the subject device to the predicate device is detailed in the Substantial Equivalence discussion below (see the comparison table below).
Both Evadyne® and Fermit N are indicated for the same use. Evadyne was designed, tested and compared to Fermit N.

Image /page/3/Picture/0 description: This image shows a world map. The map is a simple outline of the continents and islands. The continents are North America, South America, Europe, Africa, Asia, and Australia. The islands are Greenland, Iceland, Japan, and New Zealand. The map is a simple representation of the world.
Similarities: Evadyne is substantially equivalent to the predicate device in:
- Device description, ●
- Intended use, ●
- Indication for use, .
- Requirement for prescription use, ●
- Storage conditions, .
- Mechanism of polymerization (light polymerized) .
- . Container/closure
Differences: There are slight differences between the Fermit N product and Evadyne.
- . Composition - Evadyne uses a fluoroaluminosilicate glass as a filler. Fermit uses a co-polymer. Both of these compounds are used to maintain the properties of the filling material.
- Flow, flexural strength, and syringe type differ due to Evadyne is formulated to . have a lower viscosity for better ease of use (application directly to the prepared cavity from the syringe). The lower viscosity also results in Evadyne having a lower flexural strength relative to Fermit N.
We conclude that for all significant parameters, Evadyne is substantially equivalent to Fermit N. These include the photocatalytic material and mechanism, intended use, indication for use, most physical properties, design, packaging and performance.
Non clinical test data:
The Evadyne® temporary crown and bridge resin has been evaluated according to recognized consensus standards defined in ISO 10993-1. Results were found to conform to requirements (see section 15). Test data is further discussed in Section 15.
21 CFR 872.3770 lists the following recognized consensus standards:
- ANSI/ADA Specification No. 53 Polymer-Based crowns and Bridge Resins; . 1999/2005.
- . ANSI/ADA Specification No. 80 - Dental Materials - Determination of Color Stability 2001/2007.
- ISO 10477:2004 Dentistry Polymer-based crown and bridge materials .
- ISO 7405:2008 Evaluation of biocompatibility of medical devices used in dentistry. .
However, NeoDental believes that these tests are not relevant for the following reasons:
4
Image /page/4/Picture/0 description: This image shows a world map. The map is a simple outline of the continents and landmasses. The map appears to be a black and white image, with the landmasses outlined in black and the oceans appearing white.
- Evadyne is a TEMPORARY FILLING material for cavities. Physical properties have evaluated according to ISO 4049, but the other tests required in ISO-4049 are not applicable to Evadyne for the following reasons:
- o ISO-10477 is for crown bridge cement. The tests relating to Evadyne are same as ISO 4049.
- ANSI Spec 53 is identical to ISO-10477 o
- ANSI Spec 80 is for color stability of products which are to be applied to o permanent restorations having color shadings.
Biocompatibility of Evadyne
According to ISO 10993-1 Annex A, Evadyne can be categorized as shown Table 1.
