No
The device is a resin material for 3D printing dentures and the summary focuses on its physical, mechanical, and biocompatibility properties. There is no mention of AI or ML in the description, intended use, or performance studies.

No
The device, "Additively Manufactured Denture Resin," is indicated for the fabrication of denture bases. Its purpose is to create a physical dental prosthetic, not to treat or cure a disease or condition.

No

The device is a light-cured resin used for fabricating denture bases (full and partial removable dentures), which is a prosthetic and restorative function, not a diagnostic one.

No

The device is a physical material (resin) used for 3D printing dentures, 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 is for the fabrication of denture bases for full and partial removable dentures. This is a medical device used for structural support and restoration within the oral cavity.
  • Mechanism of Action: The device is a light-cured resin that is polymerized by a photo-initiator. This is a physical/chemical process for creating a solid structure, not a diagnostic test performed in vitro (outside the body) on biological samples.
  • Lack of Diagnostic Purpose: The description does not mention any diagnostic purpose, such as detecting a disease, condition, or physiological state.
  • Anatomical Site: The device is intended for use in the "oral environment," which is an in vivo (within the body) application, not an in vitro diagnostic test.
  • Performance Studies: The performance studies focus on the physical, mechanical, and biocompatibility properties of the material, which are relevant to a medical device intended for implantation or long-term contact with tissue, not an IVD.

In summary, the device is a material used to create a medical device (dentures) for use within the body, not a test performed on biological samples to diagnose a condition.

Analysis*:

    1. The subject Additively Manufactured Denture Resin and the predicate device share the same intended use and indication for use, which is the fabrication of all types of denture bases, including full and partial removable dentures. The difference between the subject and predicate devices is the type of 3D printer and the range of wavelengths used in the printing process.
      While the subject device can be used with DLP 3D printers operating in a wider range of wavelengths (385nm to 405nm), the predicate device is limited to stereolithographic printers using a 385nm light source. However, both devices are designed to utilize similar light-curing mechanisms and wavelengths that initiate the same polymerization process in the resin. These differences do not raise new questions regarding safety or effectiveness. Since both devices are designed for the same intended use, have similar technological principles, and meet the performance standards of ISO 20795-1, the differences do not affect their substantial equivalence.
    1. The subject device provides a wider range of pink shades .The different color due to the composition in the content of pigments. With the increase of the pigment content of the product to reduce the degree of transmittance, that is, the depth of light transmission is reduced, so the curing depth is reduced.
      These color variations do not raise new questions of safety or effectiveness, as both devices meet the required performance and biocompatibility standards. Therefore, the differences in color do not impact the substantial equivalence of the subject device to the predicate device.
    1. The specifications are divided into different volume according to the weight of the resin liquid. The composition of different specifications is the same, the production process is the same, only the filling quantity is different, and there is no differential effect on the physical and chemical properties and biocompatibility.
      Therefore, the difference in specification do not impact the substantial equivalence of the subject device to the predicate device.

10.0 Conclusion

The conclusions drawn from the comparison and analysis above demonstrate that the subject device is substantially equivalent to the legally marketed predicated device.
