## Intended Use

The Narval Brux is intended for protection of teeth and restorations from the forces of bruxism.

## Device Story

Narval Brux is a removable, patient-specific intraoral splint designed to protect teeth and restorations from forces associated with bruxism. The device creates a physical barrier between posterior occlusal surfaces and/or anterior incisal edges, preventing damage from grinding and potentially alleviating jaw and muscle pain. It is customized for each patient based on a clinician's prescription. The device is intended for use in a clinical or home setting under the guidance of a healthcare provider. By providing a protective interface, the device mitigates the mechanical wear and stress on dental structures caused by bruxing.

## Clinical Evidence

No clinical data were submitted. Substantial equivalence is supported by non-clinical bench testing, including biocompatibility (cytotoxicity, sensitization), static compression performance testing, and cleaning validation.

## Technological Characteristics

Patient-specific, removable, reusable, non-sterile intraoral splint. Material: Nylon. Function: Physical barrier for posterior occlusal surfaces and/or anterior incisal edges. Biocompatibility per ISO 10993.

## Predicate Devices

- SomnoMed Inc., SomnoBrux® Splint(s) ([K102909](/device/K102909.md))

Dear Ms. D'Andrea:

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. 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.

- Device Common Name Mouthguard Classification Unclassified Product Code MQC
- Predicate Devices SomnoMed Inc., SomnoBrux® Splint(s), K102909
	- Description The Narval Brux is a removable intraoral device used for protecting teeth and restorations aqainst the forces of bruxism. It consists of patient-specific splints that fit separately over the upper or lower teeth. The design of the splints is dependent on the patient needs.

The device functions as a protective barrier for teeth and restorations by creating physical separation between posterior occlusal surfaces and/or anterior incisal edges which will prevent tooth damage caused by grinding, bruxing and may help alleviate jaw and muscle pain.

The device is customized for each patient based on the clinician prescription.

- Intended Use The Narval Brux is intended for protection of teeth and restorations from the forces of bruxism.
#### Technological

- Characteristics Based on the comparative analysis of technological characteristics. Narval Brux and SomnoBrux are substantially equivalent. Both are patient-specific devices which cover posterior occlusal surfaces and/or anterior incisal edges and act as protective barriers for teeth and restorations from the effects of bruxism. Any minor design and material differences do not affect safety and performance.

## Summary of Non-Clinical and Clinical Testing

Non-clinical data submitted, referenced, or relied upon to demonstrate substantial equivalence included: biocompatibility (cytotoxicity, sensitization per ISO 10993), software validation, cleaning validation, and performance testing (static compression). The non-clinical data included in this submission demonstrate substantial equivalence to the predicate device K102909.

Clinical data were not submitted in this premarket notification.

## Substantial Equivalence Conclusion

Based on the testing performed, including biocompatibility, software validation, cleaning validation, and performance testing, it can be concluded that the subject device does not raise new issues of safety or efficacy compared to the predicate devices. The similar indications for use, technological characteristics, and performance characteristics for the proposed Narval Brux are assessed to be substantially equivalent to the predicate device.
