No
The summary describes a mechanical intraoral device with an adjustment mechanism. There is no mention of AI, ML, image processing, or data sets typically associated with AI/ML applications in medical devices.
Yes
The device is used to treat medical conditions (snoring and sleep apnea) which classifies it as a therapeutic device.
No
The device is described as an intraoral appliance used for treating snoring and mild to moderate sleep apnea by opening the airway, not for diagnosing these conditions.
No
The device description explicitly states it is an "intraoral device" consisting of physical components like "upper tray, lower tray, or both" and an "adjustment mechanism (expansion screw)". This indicates a physical medical device, not a software-only one.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to "reduce nighttime snoring and mild to moderate sleep apnea in adults." This is a therapeutic purpose, addressing a physiological condition.
- Device Description: The device is an "intraoral device" designed to "open the airway during sleep" through "mandibular advancement." This describes a physical intervention within the body.
- Mechanism of Action: The mechanism of action is "mandibular advancement," which is a mechanical action on the jaw.
- Lack of Diagnostic Function: There is no mention of the device being used to diagnose, monitor, or screen for any condition by examining samples taken from the body (like blood, urine, tissue, etc.).
IVD devices are specifically designed to perform tests on samples from the human body to provide information for the diagnosis, monitoring, or screening of diseases or conditions. This device does not fit that description. It is a therapeutic device used to treat a condition.

Device Description
The mmRNA appliance is an intraoral device used for treating snoring and mild to moderate sleep apnea. It consists of either an upper tray, lower tray, or both, and is designed to open the airway during sleep. The device is customized to each patient and features an adjustment mechanism (expansion screw) to allow it to be further customized to each patient.
The device is identical to the already-marketed mRNA appliance except the top and bottom trays interlock using the Herbst telescoping hinge instead of the mRNA flange. It is used in the predicate SomnoMed® device as well as many other devices in the market, e.g. Oasys Sleep (K181571) reference and Oasys Oral/Nasal Airway system (K030440). The mechanism of action is mandibular advancement, the same mechanism of action is used in the primary predicate device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Non-clinical Testing: No additional biocompatibility testing is necessary, as the materials are use are identical to those of the predicate device. A risk analysis was performed, which considered soreness, obstruction of breathing, tooth movement, and breakage. The product was compared to predicate devices in each area to show the risks were equivalent to the predicate devices.
Mechanical Testing: The Somnodent predicate device, K130558, provided mechanical testing on the hinge. All other components are the same as the predicate mRNA.

§ 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.”

Scientific Principles
During sleep, the muscles in the tongue and back of the throat relax, which can cause them to sag and narrow the airway. Airflow through a narrow airway is the cause of snoring. When this narrowing of the airway is severe, it results in Obstructive Sleep Apnea (OSA), where the airway closes. This can happen up to hundreds of times during the night, lasting for a minute or longer. With these closures, the brain detects the lack of oxygen and disturbs sleep to draw breath. In many cases, the individual isn't completely aware of the stoppages, which don't fully awaken the sleeper.
Device Function
The mmRNA appliance is a customized oral device featuring a lower tray and upper tray. These trays put gentle pressure on the tissue at the back of the throat to prevent the airway from collapsing sleep.
Studies have shown that customized oral devices that function by increasing the patency of the airway show comparable efficacy to continuous positive airway pressure (CPAP) devices, considered the gold standard of treatment for OSA (Oral appliance therapy in Obstructive Sleep Appea syndrome - A clinical study on therupeutic outcomes Hoekema A PhD thesis, University Medical Centre Groningen Department of Oral and Maxillofacial Surgery. pp 110, 2007). On the basis of these studies, use of oral devices has been recommended by the American Academy of Sleep Medicine for patients with mild or moderate OSA, or for those with severe OSA who are unable to tolerate the CPAP device.
The mmRNA appliance is customized on models of the patient's teeth, using standard orthodontic acrylics and standard orthodontic wires for clasps and retention. The mmRNA appliance allows for six degrees of freedom in customization, including antero-posterior (AP) adjustment, transverse (TV) adjustment, as well as permitting adjustments of the vertical dimension of occlusion (VDO).
The addition of an optional extender on the back of the device further prevents the patient's airway from collapsing during sleep.

Intended Use
To reduce nighttime snoring and mild to moderate sleep apnea in adults. These are the same indications as the primary predicate device (mRNA).
Target Population: Patients, over 18 years of age, with snoring or mild to moderate obstructive sleep apnea.
Environment of Use: Fitting of the mmRNA appliance in the dental office for patient use at home.
Comparison to Predicate Devices: The mmRNA appliance with the extender is identical in both mechanism of action and design to the predicate mRNA device, except that it advances the mandible via a telescoping hinge instead of a flange. The device allows the airway to remain open during sleep. The device is made of the same materials (standard dental acrylic, stainless steel orthodontic wires, and orthodontic adjustment screws).
The cleaning instructions for use, and labeling are identical to the already-marketed predicate device.
Shelf Life: The device is provided non-sterile. Shelf life will be identical to the predicate device. No shelf life is required as the device is custom-manufactured and immediately fitted to the patient by the dentist.
Non-clinical Testing: No additional biocompatibility testing is necessary, as the materials are use are identical to those of the predicate device. A risk analysis was performed, which considered soreness, obstruction of breathing, tooth movement, and breakage. The product was compared to predicate devices in each area to show the risks were equivalent to the predicate devices.
Mechanical Testing: The Somnodent predicate device, K130558, provided mechanical testing on the hinge. All other components are the same as the predicate mRNA.
Labeling: The labeling has been changed to reflect the hinge.
Conclusion: The subject device, mmRNA, is substantially equivalent to the primary predicate device, mRNA in its design, mechanism of action, intended use, target population, materials, testing, and labeling. The only difference between the two devices is the mmRNA advances the mandible via a telescoping hinge instead of the flange used in the mRNA.
