Yes.
The device is intended to reduce snoring and/or mild to moderate obstructive sleep apnea (OSA) in adult patients, which are medical conditions, and it actively opens the airway during sleep to achieve this.
No.
The device description and intended use clearly state that the DNA Appliance is an intraoral device designed to treat snoring and sleep apnea by opening the airway, not to diagnose the conditions. Its purpose is therapeutic intervention, not diagnostic assessment.
No
The device description explicitly states it is an "intraoral device" consisting of physical components (upper and/or lower trays) designed to be placed in the mouth. This indicates it is a hardware device, not software-only.
Based on the provided information, the DNA Appliance is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
- DNA Appliance Function: The DNA Appliance is an intraoral device designed to be worn in the mouth to physically open the airway during sleep. It is a mechanical device that directly interacts with the patient's anatomy.
- Intended Use: Its intended use is to reduce snoring and/or mild to moderate obstructive sleep apnea by physically altering the airway. This is a therapeutic or palliative function, not a diagnostic one.
- Device Description: The description clearly states it's an "intraoral device" consisting of trays, not a test kit or analytical instrument.
- Lack of Diagnostic Elements: There is no mention of analyzing biological samples, detecting biomarkers, or providing diagnostic information based on laboratory tests.
Therefore, the DNA Appliance falls under the category of a medical device used for treatment or management of a condition, not for in vitro diagnostic testing.

Device Description
The DNA appliance is an intraoral device to reduce snoring, and/or mild to moderate sleep apnea in adults 18 years of age and older. It consists of either an upper tray, or both, and is designed to open the airway during sleep. The device is customized to each patient, and features an adjustment mechanism 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 do not interlock to advance the jaw.
The DNA appliance is a customized oral device featuring a lower tray, upper tray, or both, depending on patient need. These trays put gentle pressure on the tissue at the back of the throat to prevent the airway from collapsing during sleep.
The DNA Appliance aims to expand the nasal airway through jaw expansion and mid-facial redevelopment. In doing so, an oral device may be able to permanently improve the oropharyngeal airway. Studies have shown that the DNA appliance can increase nasal cavity volume and reduce the incidence of apnea-hypopnea episodes.
The DNA appliance is customized on models of the patient's teeth, using standard orthodontic acrylics and standard orthodontic wires for clasps and retention. The DNA 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.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Non-clinical Testing: 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. No biocompatibility testing was done as all the components are the same as the predicate device.
Clinical Testing: This submittal relies on peer-reviewed literature and clinical data (RWD) demonstrating that DNA can reduce the incidence of snoring and/or mild to moderate sleep apnea, and raises no new questions of safety and efficacy as compared to mRNA, the primary predicate device.

Device Description
The DNA appliance is an intraoral device to reduce snoring, and/or mild to moderate sleep apnea in adults 18 years of age and older. It consists of either an upper tray, or both, and is designed to open the airway during sleep. The device is customized to each patient, and features an adjustment mechanism 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 do not interlock to advance the jaw.
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.
4
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. Sleep apnea has been linked to major medical conditions, including hypertension, headaches, heart disease, diabetes, depression, and more.
Device Function
The DNA appliance is a customized oral device featuring a lower tray, upper tray, or both, depending on patient need. These trays put gentle pressure on the tissue at the back of the throat to prevent the airway from collapsing during sleep.
Studies have shown that customized oral devices that function by increasing the patency of the airway show comparable efficacy to continuous positive arway pressure (CPAP) devices, considered the gold standard of treatment for OSA (Oral appliance therapy in Olstructive Skep Apnea syndrome - A clinial study on therapentic 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 DNA Appliance aims to expand the nasal airway through jaw expansion and mid-facial redevelopment. In doing so, an oral device may be able to permanently improve the oropharyngeal airway. Studies have shown that the DNA appliance can increase nasal cavity volume and reduce the incidence of apnea-hypopnea episodes.
The DNA appliance is customized on models of the patient's teeth, using standard orthodontic acrylics and standard orthodontic wires for clasps and retention. The DNA 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
No change is requested in the indication for use as compared to the predicate "indication" device (mRNA), which remains: "To reduce snoring and/or mild to moderate obstructive sleep apnea (OSA) in adult patients 18 years of age or older." In the predicate device submission for use just states adults, but then specifies the target population as 18 years of age and older as stated below.
Target Population: Patients 18 years of age and older with snoring, and /or mild to moderate obstructive sleep apnea.
Environment of Use: Fitting of the DNA appliance in the dental office for patient use at home.
Comparison to Predicate Devices: The DNA appliance with the extender is similar in both mechanism of action and design to the predicate mRNA device, except that it does not advance the mandible. 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, instructions for use, and labeling are identical to those currently used for the
5
already-marketed predicate device. These have been revised slightly since the original application for the predicate device, mRNA about 10 years ago. The precautions, warnings, risk analysis and other critical statements have not been substantially changed.
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: 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. No biocompatibility testing was done as all the components are the same as the predicate device.
Clinical Testing: This submittal relies on peer-reviewed literature and clinical data (RWD) demonstrating that DNA can reduce the incidence of snoring and/or mild to moderate sleep apnea, and raises no new questions of safety and efficacy as compared to mRNA, the primary predicate device.
