The description focuses on the mechanical design and materials of a custom-fit oral appliance for sleep apnea, with no mention of AI or ML for design, fitting, or treatment adjustment.
Yes
The device is intended to reduce nighttime snoring and mild to moderate obstructive sleep apnea (OSA) in adults by holding the mandible forward, which is a therapeutic intervention for these conditions.
No
Explanation: This device is intended to reduce night time snoring and mild to moderate obstructive sleep apnea (OSA) in adults by holding the mandible forward during sleep. It is a therapeutic device, not a diagnostic one.
No
The device description clearly describes physical, intraoral devices (maxillary and mandibular) that are CAD/CAM generated and manufactured. It discusses materials, mechanical forces, and bench testing related to physical properties, indicating it is a hardware device.
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 snoring and mild to moderate obstructive sleep apnea by physically repositioning the mandible. This is a mechanical action, not a diagnostic test performed on biological samples.
- Device Description: The description details a physical device designed to be worn in the mouth to hold the jaw forward. It does not mention any components or processes related to analyzing biological samples (blood, urine, tissue, etc.).
- Lack of IVD Characteristics: There is no mention of analyzing samples, detecting biomarkers, or providing diagnostic information based on in vitro testing.
IVD devices are specifically designed to perform tests on samples taken from the human body to provide information for diagnosis, monitoring, or screening. This device does not fit that description.

Device Description
The MicrO2 OSA device series consists of maxillary and mandibular devices that when interfaced together alleviate snoring and mild to moderate sleep apnea by holding the mandible forward during sleep, preventing the tongue and soft tissues of the throat from collapsing into the airway. These separate upper and lower arch devices are designed with twin-mated posts and are CAD/CAM generated specifically for each prescription. Designed as a patient-specific device, the MicrO2 series consists of one or multiple lower device(s) together with one or multiple mated-post upper device(s) that are manufactured to the dentist prescriber's requested advancement positions to provide a selection of gentle adjustments according to patient comfort and need. As such, prescribed advancements can be achieved by simply removing the current upper or lower device and inserting the next upper or lower device in the mandibular advancing series. The MicrO2 does not have any adjustment mechanisms to modify or maintain the mandibular position such as pistons, straps or repositioning elastics. The maximum protrusion of a MicrO2 archform is 6mm, which is comparable to the predicate device's 6mm advancement screw, measuring from plate to plate. This also negates the need for patients utilizing external controlling components such as keys, screwdrivers or ligature ties. The maximum protrusion of a MicrO2 archform is 6mm, which is comparable to the predicate device. The MicrO2's twin-mated post and lingualess design yields a small and a comfortable patient-specific mandibular advancement device. The design of the device maximizes tongue space and mandibular movement resulting in the ability to open and close during wear. The Micr02 OSA device is identical to the Somnomed MAS RXA (Classic) except for the difference in the adjustment mechanism. Any differences introduced by these modifications when compared to the predicate device, do not introduce any new safety concerns.

Summary of Performance Studies
The results of bench testing and pre-clinical testing support the above indications for use as well as the claim of Substantial Equivalence. The substantial equivalence was demonstrated through the materials that were used by the predicate devices as well as the technical and performance characteristics compared to the predicate. Compression and shear testing are important performance characteristics as they approximate the mechanical force applied by during normal use of the device. Multiple tests were performed to address fin fracture and arch fracture risks, evaluating the strength of the Micro2 device when a patient applies muscular forces during wear or physical forces during patient mishandling of the device. These tests were identified by Risk Analysis conducted in accordance with ISO-14971. The MicrO2 OSA device uses the same materials as those in the predicate devices and is a well known material for dental applications. The material manufacturing processes between Micr02 OSA device and the predicate device are identical. No new chemicals or formulas have been introduced. As such, additional biocompatibility testing was not conducted. Monomer leachablity testing was performed and compared to the predicate device.

§ 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.”

In summary, Indications for Use, patient population, Use environment and the performance data between the MICRODENTAL, Inc. MicrO2 OSA device, and the predicate device listed in Item #5 above shows nearly identical data.
From a technical design perspective, both of the devices improve the flow of air through the patient's pharyngeal space during sleep by repositioning the mandible and the use of upper and lower trays. While the device mechanics are slightly different, they both advance the lower jaw forward in order to increase the pharyngeal space. The mechanism of each device allows for adjustment of the amount of advancement based on dentist prescription. The dentist prescribes the amount of advancement increments according the physician professional assessment in the same way that the dentist adjusts the mandibular position with the pistons, screws, straps or repositioning elastics of the predicate devices.
Both devices use primarily the same material - PMMA - to provide a rigid tray.
There are no new questions of safety or efficacy raised by the MicrO2 OSA device; therefore, the device supports a claim of Substantial Equivalence.
