The appliance is patient fitted by using a computer aided manufacturing protocol.
More Information

No
The description focuses on the mechanical function of the mouthguard and mentions computer-aided manufacturing for fitting, but there is no mention of AI or ML being used in the device's operation or analysis.

Yes.

The device is intended for the "prophylactic treatment of medically diagnosed migraine pain as well as migraine associated tension-type headaches" and "prevention of bruxism and TMJ syndrome," which are therapeutic applications. It also explicitly states that it is "durable medical equipment."

No

The device is described as being used for "prophylactic treatment" and "prevention" of conditions, and it repositions the mandible to "reduce muscle tension" or "reduce trigeminally innervated muscular activity." These actions are therapeutic or preventative interventions, not diagnostic ones. Furthermore, it explicitly states that the device is "prescribed for patients with a history of a diagnosis," meaning the diagnosis has already occurred prior to the device's use.

No

The device description explicitly states it is "durable medical equipment in the form of a mouthguard" and a "removeable oral appliance," indicating it is a physical hardware device.

Based on the provided information, 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 TMJ Relax™ is a physical mouthguard that is worn on the teeth to reposition the mandible and reduce muscle tension. It does not analyze biological samples.
  • Intended Use: The intended use is for the prophylactic treatment of migraine pain, tension-type headaches, bruxism, and TMJ syndrome by physically altering the position of the jaw and reducing muscle activity. This is a mechanical/physical intervention, not a diagnostic test.

The device description and intended use clearly indicate that this is a piece of durable medical equipment used for treatment, not for diagnosing a condition by analyzing samples.

Device Description

TMJ Relax™ is durable medical equipment in the form of a mouthguard that is fitted to the teeth that temporarily provides traction on the mandible such that it repositions the mandible to reduce muscle tension. The device is a removeable home use product that a consumer may wear up to 22 hours per day, in other words except when eating or during sports activities.

The TMJ Relax™ system is a single or series of appliances prescribed for patients with a history of a diagnosis of temporomandibular joint disorder and/or migraines/tension headaches. The device is a one-part removeable oral appliance fitted on the mandibular or maxillary teeth that repositions the mandible while sleeping or during sedentary daytime use. The appliance is patient fitted by using a computer aided manufacturing protocol.

TMJ Relax™ is available by prescription by a healthcare provider (MD, DQ, DMD, or DDS) and dispensed directly to the patient by the healthcare provider as durable medical equipment. Impressions and bite registration are required to be taken by a dental healthcare provider.

To fabricate the appliance, maxillary and mandibular impressions are taken by the treating healthcare provider using an additive silicone material of the provider's choice or via digitally scanned impressions. In addition, a bite registration is taken. The patient is instructed to deprogram their bite first, and then a bite registration is taken by the preference of the treating healthcare provider. We suggest taking the bite registration in centric occlusion using a bite fork such as the George Gauge® or via a digitally scanned method. It is preferable to take the bite registration in centric occlusion using a bite fork or another method of disocclusion to account for the resin thickness of the device for most accurate transfer of the bite position indicated by the provider.

The impression samples and bite registration are shipped with provided shipping packaging to our dental lab facility for evaluation, design, and fabrication.

The raw data is obtained using dental laboratory scanners and generated in a computer-aided design software. If raw data is incomplete, the treating healthcare provider is contacted to resubmit new impressions to address the data deficiencies.

When appropriate data is fully submitted, the device is fitted to the consumer's teeth using TMJ Relax's proprietary computer aided design and manufacturing algorithm. The algorithm is consistent for each device manufactured and includes criteria to design a device with the intended mode of action.

The appliance is manufactured via a 3D printer. The manufactured TMJ Relax™ appliance provides traction to the mandible such that it allows the mandible to passively reposition and reduces muscular activity.

The device is dispensed directly to the patient by the healthcare provider to be used according to the recommended indications and instructions for use. The patient wears the initial appliance for approximately 2 weeks which allows the mandible to relax and advance into an initial new mandibular position. A patient follow-up is recommended with the treating healthcare provider after wearing the initial appliance for approximately 2 weeks. The patient is instructed to wear the appliance for at least one hour prior to the followup appointment. The treating healthcare provider has the option to either adjust the device or replace the device with a fabricated device set to a new mandibular position by the treating healthcare provider. If a secondary device is selected, an additional bite registration is taken, mailed by the treating healthcare provider to a dental lab, and a secondary appliance is fabricated to the new mandibular position.

The system may continue in a plurality of adjustments and/or appliances over a period of time which must be directed by the treating healthcare provider. The final appliance in the series may be used long term as durable medical equipment at the direction of the treating healthcare provider.

TMJ Relax™ is an easy to use, reversible method for treatment of medically diagnosed tension-type headaches, and prevention of bruxism and TMJ syndrome by action of reducing of muscular activity.

The comparison chart above provides evidence to facilitate the substantial equivalence determination between TMJ Relax™ and our chosen primary predicate, NTI-TSS NTI Tension Suppression System, and the reference device, Luco Hybrid OSA Appliance®.

There is a direct correlation between the Indications for Use Statement/Intended Use of TMJ Relax™, the NTI-TSS NTI Tension Suppression System, and Luco Hybrid OSA Appliance®. Each of the devices are oral appliances used to disocclude the teeth to reposition the mandible. Each of the devices have similar composition and biocompatiability.

The design characteristics between TMJ Relax™, the NTI-TSS NTI Tension Suppression System, and Luco Hybrid OSA Appliance® are substantially equivalent as the primary mode of action is to disocclude the teeth and allow the mandible to reposition to the new mandibular position. The TMJ Relax™ incorporates all active features of the predicate devices related to the intended use.

The primary design difference between the proposed device and the predicate/reference device is where the device sits within the oral cavity. The Luco Hybrid OSA Appliance® sits on both the maxillary and the mandibular teeth, while the TMJ Relax™ sits either the maxillary or mandibular arch, and the primary predicate device, the NTI-TSS NTI Tension Suppression System, sit on the maxillary arch involving the maxillary central incisors. Although the positions of the device within the oral cavity are different, the intent in all of the devices is disocclusion, traction, and repositioning of the mandible to the new mandibular position.

8

The proposed and predicate devices are patient specific and reuseable for the given patient. TMJ Relax™, the NTI-TSS NTI Tension Suppression System, and the Luco Hybrid OSA Appliance® are made available to patients when critical care is not required. Each of the devices are intended for patients who are willing and capable of managing its use in the home environment.

The TMJ Relax does not raise new questions of safety and effectiveness, and an internal risk analysis supports TMJ Relax is at least as safe and effective as both predicate devices.

All these facts provide evidence to facilitate the substantial equivalence determination between TMJ Relax™ and the primary predicate device, NTI-TSS NTI Tension Suppression System (K010876) and the reference device, the Luco Hybrid OSA Appliance® (K160477).

9. Non-Clinical Performance Data

During the development of TMJ Relax™ Standards ISO 20795-2, ANSI 139-2012, and ISO 10993-1 were carefully considered to ensure compliance. As per the 10993-1 quidance document, the TMJ Relax™ device is classified as a surface contacting device with the mucosal membrane for long term use > 30 days. The contact duration is based on ISO 10993-1, Clause 5.3: medical devices whose cumulative sum of single, multiple or repeated contact time exceeds 30 d.

The TMJ Relax device complies with all applicable standards.

Clinical Performance Data 10.
