Intended Use
The Dorsal Appliance is intended for the reduction of night time snoring and mild to moderate obstructive sleep apnea (OSA) in adults 18 years of age or older.
Device Description
The Dorsal Appliance is comprised of upper and lower customized acrylic splints for the treatment of mild to moderate sleep apnea. The upper splint comprises bilateral turnbuckle adjustment mechanisms. The device aims to improve the patient's air exchange thereby reducing snoring and apnea by increasing the pharyngeal space through anterior repositioning of the mandible.
More Information

No
The description focuses on mechanical adjustment and material properties, with no mention of AI or ML terms or functionalities.

Yes.
The device is intended for the reduction of night time snoring and mild to moderate obstructive sleep apnea (OSA), which are medical conditions, and aims to improve the patient's air exchange, indicating a therapeutic purpose.

No

Explanation: The document states that "The Dorsal Appliance is intended for the reduction of night time snoring and mild to moderate obstructive sleep apnea (OSA)". This indicates a treatment or therapeutic function, not a diagnostic one.

No

The device description explicitly states it is comprised of "upper and lower customized acrylic splints," which are physical hardware components, not software.

No, this device 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 Dorsal Appliance is a physical device worn in the mouth to reposition the jaw and improve airflow. It does not analyze biological samples.
  • Intended Use: The intended use is for the reduction of snoring and sleep apnea, which is a physical treatment, not a diagnostic test.

The information provided clearly describes a medical device used for treatment, not for diagnosing a condition by analyzing samples.

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 performance testing of the device material was provided. Because the identical material is used for both the subject and predicate devices, these performance results support the finding of substantial equivalence. The results included general properties (water solubility and absorption) and physical properties (tensile and flexural strength, and elastic modulus).
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 Dr. Warden:

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.

Classification Name:Device, Anti-Snoring
Regulation Number,
Name:872.5570, Intraoral devices for snoring and intraoral devices for snoring and

Device Product Code:LRK
Submission Purpose:The Dorsal Appliance is a modification of the Acrylic Herbst Appliance.
Device Description:The Dorsal Appliance is comprised of upper and lower customized acrylic
splints for the treatment of mild to moderate sleep apnea. The upper splint
comprises bilateral turnbuckle adjustment mechanisms.
The device aims to improve the patient's air exchange thereby reducing
snoring and apnea by increasing the pharyngeal space through anterior
repositioning of the mandible.
Intended Use:The Dorsal Appliance is intended for the reduction of night time snoring and
mild to moderate obstructive sleep apnea (OSA) in adults 18 years of age or
older.
Materials:Medical grade polymethylmethacrylate (acrylic splints) and stainless steel
(adjustment screw mechanism)
Predicate Devices:Primary: Acrylic Herbst Appliance (Gergen's, K113126)
Reference: Dorsal Appliance (Dynaflex Inc., K103076)
Performance Data: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 performance testing of the device material was provided.
Because the identical material is used for both the subject and predicate
devices, these performance results support the finding of substantial
equivalence. The results included general properties (water solubility and
absorption) and physical properties (tensile and flexural strength, and elastic
modulus).
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.

From the chart above, the only differences between the subject device and Conclusion: the primary predicate is the type of advancement mechanism used and the adjustable range allowed by the devices. Although the advancement mechanism differs, the type used for the subject device is also used in other similar intra-oral devices such as the reference predicate device (Dorsal Appliance). Therefore, the difference in the type of advancement mechanism does not raise any new safety and effectiveness questions. The adjustable range of the primary predicate device is slightly higher than the subject device; however this range falls within the limits of other similar predicate devices.

In comparison to the predicate device, the Dorsal Appliance has

  • the same intended use (as described above),
  • . technological characteristics which do not raise new questions of safety and effectiveness.

Therefore the Dorsal Appliance can be found substantially equivalent to the predicate device.
