Intended Use
The Twilite Appliance ® is intended to reduce night time snoring and mild to moderate obstructive sleep apnea (OSA) in adults 18 years and older.
Device Description
The Twilite Appliance ® is a customized oral device intended to mitigate night-time snoring and mild to moderate obstructive sleep apnea. The Twilite Appliance ® is to continuously hold the mandible in an advanced position to prevent the tongue from compressing against the oropharyngeal wall keeping the airway open during sleep.
More Information

No
The summary describes a mechanical oral appliance and does not mention any AI/ML components or related performance metrics.

Yes
The device is intended to reduce night time snoring and mild to moderate obstructive sleep apnea, which are medical conditions, and it physically manipulates the mandible to keep the airway open for therapeutic purposes.

No
The device description and intended use state that the device is intended to treat snoring and sleep apnea by repositioning the jaw, not to diagnose the conditions. It does not mention any diagnostic functions, performance metrics typical of diagnostic devices, or input imaging.

No

The device description clearly states it is a "customized oral device" and mentions bench testing for physical properties like flexural strength and water absorption, indicating it is a physical hardware device.

Based on the provided information, the Twilite Appliance ® is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is to reduce snoring and mild to moderate obstructive sleep apnea by physically repositioning the mandible. This is a therapeutic intervention, not a diagnostic test performed on samples from the human body.
  • Device Description: The description clearly states it's an oral device that holds the mandible in an advanced position to keep the airway open. This is a mechanical action, not a diagnostic process.
  • Lack of IVD Characteristics: The document does not mention any of the typical characteristics of an IVD, such as:
    • Analyzing biological samples (blood, urine, tissue, etc.)
    • Detecting or measuring substances in those samples
    • Providing information for the diagnosis, monitoring, or treatment of a disease or condition based on the analysis of samples.

The Twilite Appliance ® is a medical device, specifically an oral appliance used for the treatment of snoring and sleep apnea.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Non-clinical performance testing:
Bench Testing: The materials for the trays are made from materials cleared for use as dental trays. In additions to the materials meeting dental standards, we performed testing after manufacture and aging for: Flexural strength / Fracture Toughness.
Biocompatibility / Materials: The materials in contact with the patient have been cleared for the intended use of dental trays. The materials are dental tray materials cleared under K153490.
Clinical: Based upon Twilite Appliance ® design concept, it was determined that no clinical testing would be required as we are identical in this principle of operation and technology as well as performance specification, namely maximum advancement distance. Also, the specifications of the ability to advance the lower tray are the same and the maximum advancement is similar to the predicate.

§ 872.5570 Intraoral devices for snoring and intraoral devices for snoring and obstructive sleep apnea.

(a)
Identification. Intraoral devices for snoring and intraoral devices for snoring and obstructive sleep apnea are devices that are worn during sleep to reduce the incidence of snoring and to treat obstructive sleep apnea. The devices are designed to increase the patency of the airway and to decrease air turbulence and airway obstruction. The classification includes palatal lifting devices, tongue retaining devices, and mandibular repositioning devices.(b)
Classification. Class II (special controls). The special control for these devices is the FDA guidance document entitled “Class II Special Controls Guidance Document: Intraoral Devices for Snoring and/or Obstructive Sleep Apnea; Guidance for Industry and FDA.”

Dear Paul Dryden:

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.

Non-clinical performance testing

Bench Testing

The materials for the trays are made from materials cleared for use as dental trays. In additions to the materials meeting dental standards, we performed testing after manufacture and aging for:

  • . Flexural strength / Fracture Toughness

Biocompatibility / Materials

The materials in contact with the patient have been cleared for the intended use of dental trays. The materials are dental tray materials cleared under K153490.

Clinical

Based upon Twilite Appliance ® design concept, it was determined that no clinical testing would be required as we are identical in this principle of operation and technology as well as performance specification, namely maximum advancement distance. Also, the specifications of the ability to advance the lower tray are the same and the maximum advancement is similar to the predicate.
