Intended Use
Silent Nite Sleep Appliance with the Glidewell Hinge is indicated to reduce snoring and mild to moderate obstructive sleep apnea (OSA) in adults 18 years of age or older. It is worn while sleeping to support the lower jaw in a forward position prescribed by the dentist. The appliance is removable by the patient.
Device Description
The subject device, Silent Nite® Sleep Appliance with the Glidewell Hinge™, is a mandibular advancement device (MAD). It holds the mandible in a protrusive position to increase the patient's ability to exchange air and decrease air turbulence, thus improving airflow during sleep. The subject device, Silent Nite® Sleep Appliance with the Glidewell Hinge™, consists of upper and lower trays, and an engaging mechanism made of stainless-steel, which is the Glidewell hinge. Optional orthodontic (elastic) bands are provided as accessories. The trays consist of a soft polyurethane inner layer that provides patient comfort and a hard polyester outer layer for durability. The hinge is adjustable by turning an inner adjustment screw with a hex driver, enabling the amount of mandibular advancement prescribed by the clinician. The design allows for the advancement of the mandible to be adjusted (increased) in 0.25 mm increments up to 10 mm. The subject device, Silent Nite® Sleep Appliance with the Glidewell Hinge™, is customized to conform to the patient's upper and lower dentition based on the clinician's prescription. Upon receipt of the prescription, models for the trays are made and used during the thermoforming fabrication of the upper and lower trays.
More Information

No
The description focuses on the mechanical design and materials of a mandibular advancement device. There is no mention of AI, ML, or any computational analysis of data for diagnosis, treatment planning, or device function.

Yes

The device is indicated to reduce snoring and mild to moderate obstructive sleep apnea (OSA), which are medical conditions, and it achieves this by supporting the lower jaw to improve airflow during sleep, thereby providing a therapeutic effect.

No

Explanation: The device, the Silent Nite Sleep Appliance with the Glidewell Hinge, is described as a mandibular advancement device (MAD) intended to reduce snoring and mild to moderate obstructive sleep apnea by repositioning the jaw. Its function is to treat a condition, not to diagnose it.

No

The device description clearly outlines physical components like upper and lower trays, a stainless-steel hinge, and optional elastic bands, indicating it is a hardware device.

Based on the provided text, 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 supporting the lower jaw. This is a mechanical action, not a diagnostic test performed on biological samples.
  • Device Description: The device is a physical appliance worn in the mouth. It does not involve the analysis of blood, urine, tissue, or any other biological specimen.
  • Lack of IVD Characteristics: The description does not mention any components or processes typically associated with IVDs, such as reagents, assays, or analysis of biological markers.

IVD devices are used to examine specimens from the human body to provide information for diagnosis, monitoring, or screening. This device does not perform any such function.
