Device Story

NextDent Jet Denture Base and Teeth are acrylate-based, light-curable resins; used with 3D Systems Projet MJP 5600 printers and 3D Sprint software. MultiJet Printing technology jets ultra-thin layers of photopolymer onto a build tray; each layer cured immediately by UV light. Process repeats until part completion; support material removed; parts cleaned and finished using conventional dental methods. Used in dental clinics/labs by dental professionals. Enables fabrication of custom dental prosthetics; bonding of artificial teeth to denture base possible. Output is a physical dental appliance; aids in patient rehabilitation for missing teeth or dental structures.

Clinical Evidence

Bench testing only. Compliance with ISO 20795-1:2013 (denture base polymers) and ISO 10477:2020 (polymer-based crown/veneering materials).

Dear Bart Romanus:

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 (the 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 available 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.
