Intended Use

The Braces on Demand Bracket is intended for use as a clear, plastic bracket system to provide orthodontic movement of natural teeth.

Device Story

Braces on Demand Bracket system consists of 3D-printed, clear plastic orthodontic brackets. Clinicians use software to design brackets based on patient dentition; brackets are then 3D-printed using photopolymer resin, washed, and UV-cured. Brackets feature an integral hook for elastics/springs and a mechanical dovetail undercut base for adhesive bonding to the facial surface of teeth. Used by dental professionals in clinical settings to provide orthodontic tooth movement. The system allows for in-house printing or delivery of manufactured brackets. Clinicians bond brackets to teeth using standard orthodontic adhesives and tools. The device benefits patients by providing an aesthetic, custom-fit orthodontic appliance for correcting malocclusions.

Clinical Evidence

Bench testing only. No clinical data provided. Testing included bond strength, hook strength, and dimensional stability/accuracy compared to predicate devices. Biocompatibility testing performed per ISO 10993 (cytotoxicity, intracutaneous reactivity, sensitization, and systemic toxicity).

Technological Characteristics

3D-printed orthodontic brackets made of biocompatible photopolymer resin. Features mechanical dovetail undercut base for bonding. Manufacturing utilizes SLA 3D printing (Formlabs Form 2/3), automated washing (Form Wash), and UV curing (Form Cure). Software-driven design and fabrication via STL file format. No electronic components in the final bracket.

Indications for Use

Indicated for orthodontic treatment of malocclusions in patients with primary, permanent, or mixed dentition.

Regulatory Classification

Identification

Dear Patsy Trisler:

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.

| Indications for Use<br>Statement: | The Braces on Demand Bracket System is intended for use as<br>a clear, plastic bracket system to provide orthodontic movement of<br>natural teeth. | |
| Device Description<br>and Summary of<br>Technological<br>Characteristics | The proposed device is a 3D-printed bracket system that directly<br>bonds to either primary teeth, permanent teeth, or mixed dentition<br>to provide for orthodontic treatment for patients with<br>malocclusions. Each bracket is 3D printed using a photopolymer<br>denture resin. | |
| | The Braces on Demand Bracket System has an integral hook<br>design, which allows for attachment of accessories such as<br>elastics or springs to assist the clinician in producing the desired<br>tooth movement. The hook position on the Braces on Demand<br>brackets can be on the mesial occlusal tiewing or the distal<br>occlusal tiewing, similar to traditional orthodontic brackets. | |
| | The application and removal of the Braces on Demand brackets<br>are similar to other orthodontic brackets in that it requires<br>orthodontic adhesive for bonding and standard orthodontic tools<br>and techniques for de-bonding. The bonding surface of the<br>bracket is a mechanical dovetail undercut design, allowing the<br>bracket to mechanically retain the adhesive and bond to the facial<br>surface of the tooth. | |

### Biocompatibility

The following ISO 10993 testing was performed according to Good Laboratory Practices to assess the safety and biocompatibility of the plastic material:

Part 5 (Cytotoxicity Elution - MEM),

The reference device, utilizing the same exact materials and processes, also underwent the following testing:

Part 10 (Intracutaneous/Intradermal) Reactivity),

Part 10 (Maximization for Delayed-Type Hypersensitivity),

Part 11 (Subacute Systemic Toxicity)

This testing has shown that the material is safe and biocompatible for the stated intended use.

Animal | Human Testing

No animal or human testing are required for this product because it is composed of the same materials, is designed similarly, and is manufactured by method similar to the predicate device.

{6}------------------------------------------------

Comparison to The Braces on Demand Bracket System, compared to the two Predicate Devices: predicate devices:

- . The intended use is the same.
- . The mechanisms of action (software and bracket systems) are similar.
- I The material used to make the brackets is similar to the predicate and is produced in the same manner (by additive manufacturinq) as the reference device.
- I The software used during the manufacturing processes is similar.

Based on the documentation presented in the 510(k), as Substantial Equivalence summarized above, it can be concluded that this software system Conclusion and the produced brackets are substantially equivalent to the predicate devices.
