The summary describes a dental resin used with CAD/CAM and additive printing, but there is no mention of AI or ML in the intended use, device description, or performance studies.
No
This device is a resin used to fabricate dental prostheses like dentures. It is a material used in the manufacturing process rather than a device that directly treats a condition or restores a function in the body.
No
Explanation: The device is a resin used for fabricating dental prostheses like dentures. Its intended use is for manufacturing and repair, not for diagnosing conditions or diseases.
No
The device description clearly states that Halley resin is a methacrylate-based, light-cured resin, which is a physical material, not software. The intended use also describes it as a resin for fabricating dentures and other dental appliances.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use/Indications for Use: The intended use is for fabricating denture bases and other dental appliances in dental laboratories. This is a manufacturing process for a medical device that will be placed in the patient's mouth. It does not involve testing samples from the human body to provide diagnostic information.
- Device Description: The device is a resin used for 3D printing or traditional fabrication of dental prostheses. It's a material used to create a physical device, not a test or assay.
- Lack of IVD Characteristics: There is no mention of analyzing biological samples, detecting analytes, or providing diagnostic information about a patient's health condition.
The device is a dental material used in the fabrication of dental prostheses, which are considered medical devices, but the material itself is not an IVD.

6. Substantial Equivalence:
Technological Characteristics:
For the purpose of substantial equivalence, the proposed Halley resin is compared to the predicate device. NextDent™ Denture / E-Denture (K162572). The predicate device, NextDent™ Denture / E-Denture (K162572) is being compared to the proposed device Halley resin to establish substantial equivalence to the proposed device Halley resin, specifically for performance and processing similarities related to 3D additive printing.
In addition to the primary predicate device, Pour Acrylic (K161330) is included as a reference device in support of substantial equivalence. The reason for inclusion of the reference device, Pour Acrylic (K161330), is to support similarities in technological properties and performance characteristics to the proposed device.
The proposed, predicate, and reference devices have been tested according to the requirements of ISO 20795-1:2013 (Dentistry - Base polymers - Part 1: Denture base polymers) as Type 2 or 4 materials. Table 5.1 compares the proposed device, Halley resin, the predicate device, NextDent™ Denture / E-Denture (K162572), and the reference device, Pour Acrylic (K161330).
