(194 days)
No
The description focuses on the mechanical function of the device as a mandibular repositioner and does not mention any AI/ML components or capabilities.
Yes
The device is intended for the reduction of snoring and mild to moderate obstructive sleep apnea, which are medical conditions, and functions by supporting the lower jaw to increase pharyngeal space for improved air exchange.
No
The device is described as a mandibular repositioner intended to reduce snoring and mild to moderate obstructive sleep apnea by increasing pharyngeal space, which is a treatment function, not a diagnostic one.
No
The device description clearly states it consists of physical components: an upper and lower acrylic splint and an adjustable Herbst style mechanism. It is a physical appliance worn by the patient.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, tissue) to provide information about a person's health. This testing is done outside of the body (in vitro).
- REST EAZY Appliance Function: The REST EAZY Appliance is a physical device worn inside the mouth to reposition the jaw. It directly interacts with the patient's anatomy to treat a condition (snoring and sleep apnea). It does not analyze any biological samples.
The description clearly indicates it's a medical device used for treatment, not for diagnostic testing of biological specimens.
N/A
Intended Use / Indications for Use
The REST EAZY Appliance is intended for use in adult patients for the reduction of snoring and mild to moderate obstructive sleep apnea. The REST EAZY Appliance is worn while sleeping to support the lower jaw in a forward position as prescribed by the dentist. The appliance is removable by the patient.

Device Description
The proposed REST EAZY Appliance device consists of an upper and lower acrylic splint, custom fabricated to the patient's teeth. The splints are connected to each other via the REST EAZY adjustable Herbst style mechanism that orients the jaw in a predetermined relationship. These devices function as a mandibular repositioner, which increases the pharyngeal space. An enlarged pharyngeal space assists the patient with improved air exchange. The device is custom fit for each patient, as prescribed by the dentist.
Per 21 CFR 872.5570, intraoral devices for snoring and/or obstructive sleep apnea 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, tonque retaining devices, and mandibular repositioning devices. The proposed REST EAZY Appliance is considered a mandibular repositioning device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
The following performance data was considered in support of the substantial equivalence determination.
Performance Guidelines: 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." [67 FR 68512, Nov. 12, 2002]
Biocompatibility: The predicate and subject devices are considered to be external communicating devices of permanent exposure (>30 days) per ISO 7405 and surface-contacting devices (mucosa) of permanent contact (>30 days) per ISO 10993-1. There are no new materials being used in the proposed device. Materials utilized for the REST EAZY Appliance are identical to the primary materials used in the predicate device for the same intended use. Both the predicate and REST EAZY Appliance are made from stainless steel and dental acrylic. Biocompatibility testing has been previously established through biocompatibility testing for the Variflex (K033632) material.
Non-Clinical Testing: The following physical properties testing was conducted on the Variflex (K033632) material.
- Ultimate Tensile Strength
- Young's Modulus
- Hardness (Shore D)
- Water Sorption
- Water Solubility
Risk Analysis: A risk analysis including an evaluation of the materials of construction and design was performed. The prescribing dentist must recognize the potential for TMJ soreness, soft tissue soreness, and dentition complications (soreness, motion, loosening) when using a mandibular advancement device. The contraindications, warnings, precautions, storage directions, prescription preparation instructions, fitting and adjustment directions are provided to avoid potential problems from arising or persisting with the dentition, tissue, or joints. No significant new risks were identified.

Dear Felicia Ruley:
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.
