Regulatory Classification
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.
Special Controls
*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 Alyssa Schwartz:
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.
{1}------------------------------------------------
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820); and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to http://www.fda.gov/MedicalDevices/Safety/ReportaProblem/default.htm.
For comprehensive regulatory information about mediation-emitting products, including information about labeling regulations, please see Device Advice (https://www.fda.gov/MedicalDevices/DeviceRegulationandGuidance/) and CDRH Learn (http://www.fda.gov/Training/CDRHLearn). Additionally, you may contact the Division of Industry and Consumer Education (DICE) to ask a question about a specific regulatory topic.

| Device Description: | The DaSoft Advanced Dental Appliance is an intraoral device designed to be<br>worn during sleep to reduce snoring. The device includes a manually<br>adjustable tongue sleeve to position the tongue and surrounding tissues<br>forward in order to increase the patient's pharyngeal space, improving the<br>ability to exchange air and decreases air turbulence. The device is<br>manufactured using only medical grade ethylene vinyl acetate (EVA)<br>polymer. | | |
| Intended Use: | Intraoral device for reduction in snoring. | | |
| Indications for Use: | The DaSoft Advanced Dental Appliance is indicated to reduce snoring in<br>adult patients age 18 years or older. | | |
| Technology Comparison: | The subject and predicate devices are nearly identical in design and<br>functionality. Both the DaSoft Advanced Dental Appliance and its predicates<br>are intraoral mouth pieces that are molded to the patient's teeth using a boil<br>and bite method. The DaSoft Advanced Dental Appliance includes the<br>tongue sleeve which gently positioning the tongue in a forward position while<br>sleeping, which provides a snoring reduction mechanism, which is<br>substantially equivalent to the mode of action of the predicates. The subject<br>and predicate device are provided non-sterile and use similar packaging<br>systems. Table 1 below summaries the comparison. | | |
