More Information

No
The summary describes a material (polymers) used for fabricating dentures, with no mention of software, algorithms, or any AI/ML related terms or concepts.

No
The device is a material used for a denture base, which replaces missing teeth. It is a prosthetic device, not a therapeutic one that treats or cures a disease or condition.

No
The device, "Denture Base Polymers," is used for fabrication and repair of dentures, which is a therapeutic and restorative purpose, not a diagnostic one. It does not identify or detect a disease or condition.

No

The device description clearly states it is composed of powder and liquid materials (polymethyl methacrylate and methyl methacrylate), which are physical components, not software.

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 and repair of partial and full denture base for patients with missing teeth." This is a restorative dental device used to replace missing teeth, not a device used to perform tests on samples taken from the human body to provide information about a physiological state, health, or disease.
  • Device Description: The description details the chemical composition of the materials used to create the denture base. This aligns with a material used for fabrication, not a diagnostic test.
  • Lack of Diagnostic Elements: There is no mention of analyzing biological samples, detecting analytes, or providing diagnostic information.
  • Anatomical Site: While it's used "on teeth," this refers to the placement of the fabricated denture, not a diagnostic test performed on the teeth themselves or samples from the teeth.
  • Performance Studies: The statement "Clinical performance testing has not been performed on the subject device" further supports that this is not a diagnostic device, as IVDs typically require performance studies related to their diagnostic accuracy.

In summary, the device is a material used to create a dental prosthesis, which falls under the category of a medical device, but not specifically an In Vitro Diagnostic device.

Dear Maggie Zheng:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

9. Summary of Biocompatibility

The new device, Denture Base Polymers, is substantially equivalent to the predicate devices that have been on the market for years and with no clinical adverse events. The formulation of new device does not contain any new or non-conventional chemicals compared to the legally marketed predicate device.

6

We selected our Denture Base Polymers (Model: Type 2 Class 1) as the representative in biocompatibility tests and those biocompatibility test reports can be used in the biological evaluation of Denture Base Polymers.

Biocompatibility tests were performed fully following the ISO 10993 standards. The test items include Cytotoxicity; Sensitization; Irritation or Intracutaneous Reactivity; Acute Systemic Toxicity; Material-Mediated Pyrogenicity; Subchronic Toxicity; Genotoxicity and Implantation.

10. Clinical Performance Data

Not applicable. Clinical performance testing has not been performed on the subject device.

11. Summary of Substantial Equivalence

As with the comparison shown in substantial equivalence discussion, these devices are same or similar in almost all aspects. The details of indications for use, composition of materials, physical properties, labeling, stability/shelf life and cautions are slightly different, but the minor differences between the new device and the predicate devices are out of significance and do not affect neither the general intended use nor substantial equivalence.

We conclude that our Denture Base Polymers is substantially equivalent to the predicate devices described herein.
