Intended Use
NextDent Base is for dental professional use only and intended for the manufacturing of denture bases to support artificial teeth to form full or partial removable dentures.
Device Story
NextDent Base is an acrylate-based light-cure resin used for 3D printing denture bases. The device is intended for use in dental laboratories by dental professionals. The process involves using a VAT-based 3D printer (e.g., NextDent 5100 Figure 4) and 3D Sprint software to print the resin in layers, with each layer cured by UV light. Post-printing, parts are cured in a UV light chamber (e.g., NextDent LC-3DPrint Box) and finished using conventional dental methods. The device enables the fabrication of custom denture bases, supporting artificial teeth for removable dentures. The resin's mechanical properties and biocompatibility are verified to ensure safety and performance for permanent oral contact.
Clinical Evidence
Bench testing only. No clinical data. Testing included biocompatibility per ISO 10993-1:2018 (cytotoxicity, sensitization, irritation, genotoxicity, systemic toxicity) and ISO 7405:2018. Mechanical performance was verified against ISO 20795-1:2013, including flexural strength, modulus, impact strength, sorption, solubility, and color stability. Results confirmed compliance with requirements for denture base polymers and substantial equivalence to the predicate.
Technological Characteristics
Pre-mixed acrylate-based UV light-cure resin containing pigments and photo-initiators. Polymerization via UV light source in a 3D printer and post-curing chamber. Compliant with ISO 20795-1:2013 and ISO 10993-1:2018. Non-sterile. Shelf life of two years.
Indications for Use
Indicated for dental professionals to manufacture denture bases supporting artificial teeth for full or partial removable dentures.
Regulatory Classification
Identification
A denture relining, repairing, or rebasing resin is a device composed of materials such as methylmethacrylate, intended to reline a denture surface that contacts tissue, to repair a fractured denture, or to form a new denture base. This device is not available for over-the-counter (OTC) use.

Dear Patsy Trisler, Jd, Rac:
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.

| VIII. SUMMARY OF<br>TESTING<br>[PERFORMANCE<br>DATA] | NextDent Base is tested for mechanical characteristics as<br>part of the product specification. The most applicable<br>standard for mechanical characteristics determination of<br>denture bases is ISO 20795-1:2013 Dentistry - Base<br>polymers - Part 1 Denture base polymers. | | | | | | |
| Biocompatibility<br>Testing: | According to both ISO 7405:2018 and ISO 10993-1: 2018<br>NextDent Base is considered a surface device, in contact<br>with intact oral mucosa, permanent (> 30 days), repeated<br>use.<br>The ISO 10993-1:2018 standard, including parts 3, 5, 10,<br>12, 17, 18 and 23 was followed and the following applicable<br>biological safety hazard endpoints were addressed:<br>• Chemical characterization<br>• Cytotoxicity<br>• Acute systemic toxicity<br>• Subacute/sub chronic toxicity<br>• Irritation or intracutaneous reactivity<br>• Sensitization<br>• Genotoxicity<br><br>In addition, the following risks were considered based on a<br>risk assessment, taking into account the specific nature and<br>duration of exposure to the device<br>• Material mediated pyrogenicity<br>• Chronic toxicity<br>• Presence of phthalates<br><br>In addition, ISO 10993-17 and -18 and ISO/TS 21726 were<br>followed to identify and quantitate the extractables and/or<br>leachables that may be released from the test article to | | | | | | |
{7}------------------------------------------------
| | NextDent Base is compliant to the applicable requirements<br>defined in ISO 10993 including parts 1, 3, 5, 10, 12, 17, 18<br>and 23, ISO 7405 and ISO/TS 21726 for permanent medical<br>devices and therefore biocompatible. |
|---------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Bench Testing | NextDent Base is tested according to the methods in the<br>industry standard ISO 20795-1:2013 Dentistry – Base<br>polymers - Part 1 Denture base polymers. |
| | NextDent Base is compliant to the requirements defined in<br>ISO 20795-2:2013 for Type 4 light activated material except<br>for ultimate flexural strength, flexural modulus and water<br>solubility. Comparative testing showed that elasticity and<br>impact resistance properties are substantially equivalent to<br>the predicate. NextDent Base is regarding water solubility<br>compliant to requirements defined in ISO 20795-1:2013 for<br>type 2 autopolymerizable materials. The following bench<br>tests are conducted on NextDent Base:<br>Surface characteristics Polishability Color Color stability Translucency Freedom from porosity Ultimate flexural strength Flexural modulus Charpy impact strength Bonding to synthetic polymer teeth Sorption Solubility Dynamic fatigue Fracture work |
| | The mechanical performance of NextDent Base printed on<br>the NextDent 5100 printer is verified confirming its sufficient<br>repeatability and robustness regarding print orientation,<br>placement, and resin reuse. |
| Reprocessing, Sterility<br>and Shelf-Life Testing | The device is provided non-sterile.<br>From the Shelf-life testing, NextDent Base has a shelf life of<br>two years. |
| IX. CONCLUSIONS | NextDent Base and the predicate have the same intended<br>use and similar technological characteristics. |
|-----------------|---------------------------------------------------------------------------------------------------------------------|
| | The results of the performed tests show that NextDent Base<br>meets the applicable requirements of ISO 20795-1:2013 |
{8}------------------------------------------------
| Dentistry - Base polymers – Part 1 Denture base polymers<br>and confirm that the device performs similarly to the<br>predicate device. |
|----------------------------------------------------------------------------------------------------------------------------------------|
| It is therefore concluded that NextDent Base performs as<br>intended and is substantially equivalent to the predicate<br>device. |
