Intended Use
The Acrylic Herbst Appliance is intended for the reduction of night time snoring and mild to moderate obstructive sleep appea (OSA) in adults 18 years of age or older. When a DentiTrac® micro-recorder is embeded into the Acrylic Herbst Appliance, the micro-recorder is intended to measure patient compliance to oral device/appliance therapy in combination with the DentiTrac® System.
Device Description
The Acrylic Herbst Appliance with Micro-Recorder is comprised of upper and lower customized acrylic splints which are connected bilaterally via a telescoping Herbst mechanism for the treatment of mild to moderate sleep apnea. The micro-recorder is embedded within the appliance. The device aims to improve the patient's air exchange thereby reduce snoring and apnea by increasing the pharyngeal space through anterior repositioning of the mandible. The micro-recorder permits a patient's compliance to prescribed oral therapy to be monitored. The patient contacting portions of the appliance are comprised of medical grade polymethylmethacrylate (acrylic splints) and) which are connected bilaterally via a stainless steel (Herbst) mechanism.
More Information

No
The document describes a mechanical oral appliance with an embedded micro-recorder for compliance tracking. There is no mention of AI, ML, or any related technologies in the device description, intended use, or performance studies.

Yes
The device is intended for the reduction of night time snoring and mild to moderate obstructive sleep apnea (OSA), which are therapeutic indications.

No

The device is intended for treatment (reduction of snoring and OSA, improvement of air exchange) and monitoring compliance, not for diagnosing conditions.

No

The device description clearly states it is comprised of physical components (acrylic splints, stainless steel mechanism, micro-recorder) and is intended for physical interaction with the patient's anatomy.

Based on the provided information, the Acrylic Herbst Appliance with Micro-Recorder is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • Device Function: The Acrylic Herbst Appliance is a physical device worn in the mouth to reposition the jaw and improve airflow. The micro-recorder measures compliance, not biological markers or conditions within a sample.
  • Intended Use: The intended use is for the reduction of snoring and sleep apnea, and for measuring patient compliance. These are not diagnostic purposes in the sense of analyzing biological samples.
  • Device Description: The description focuses on the physical components and how they interact with the patient's anatomy.
  • Lack of IVD Indicators: There is no mention of analyzing biological samples, detecting biomarkers, or performing any kind of laboratory test.

The device is a therapeutic and monitoring device, not a diagnostic one.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

The materials and fabrication processes used in the manufacture of the subject device are identical to the materials and fabrication processes used in the manufacture of the predicate device. Because material biocompatibility was accepted for the predicate and because there are no differences in manufacturing which could affect biocompatibility, additional biocompatibility testing was not supplied in support of this clearance. Data regarding mechanical and thermal performance testing of the device material and provided as follows:
Mechanical Tests: Tensile strength, Elongation at tear, E-modulus (ISO 527), Flexion strength (ISO 178), Impaction strength 23°C (ISO 179), Notched 23°C, Rockwell hardness (ISO 2039).
Thermal Tests: Vicat softening point (ISO 306 (B)), Thermoform resistance (ISO 75 (A)), (ISO 75 (B)).
Because the identical material is used for both the subject and predicate devices, these performance results were found to be satisfactory and therefore support the finding of substantial equivalence. Clinical testing of the subject device was not used in support of clearance. Per the Class II Special Controls Guidance Document: Intraoral Devices for Snoring and/or Obstructive Sleep Apnea; Guidance for Industry and FDA, a risk analysis was performed with respect to the subject device. The risks identified in the guidance (e.g., intraoral gingival, palatal, or dental soreness; TMJ Dysfunction Syndrome; obstruction of oral breathing and loosening or flaring of lower anterior teeth or general tooth movement) and those detected by the risk analysis were mitigated though the use of biocompatible materials identical to those used in the predicate and the use of appropriate labeling.

§ 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.”

Dear Karen E. Warden, Ph.D .:

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. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
