Intended Use

Protect-It Custom Fit Dental Guard is indicated for protection against bruxism or nighttime teeth grinding. It is intended to reduce damage to teeth associated with bruxing or nighttime teeth grinding.

Device Description

Protect-It Custom Fit Dental Guard is an over-the-counter device to be used by lay people for protection against the effects of nighttime teeth grinding. It is made of a single thermoplastic resin, ethylene vinyl acetate copolymer, EVA, which is easily molded to the teeth when heated. It is a full-occlusal guard worn on the upper teeth, providing a cushion to separate the upper and lower teeth and keep them apart while sleeping, thus reducing the damage to teeth associated with bruxism.

AI/ML Overview

The provided text is a 510(k) premarket notification for a medical device: DOC Brands, Inc.'s Protect-It Custom Fit Dental Guard. This type of submission aims to demonstrate substantial equivalence to a predicate device, rather than proving the device meets specific acceptance criteria through a clinical study as would typically be done for a new or high-risk device.

Therefore, the document does not contain the information requested in your prompt regarding acceptance criteria, a test set, expert adjudication, MRMC studies, standalone performance, or training set details for an AI/ML device.

The relevant sections of the document describe:

  • Substantial Equivalence Discussion: This is the core of the submission, comparing the subject device to a predicate (DenTek Oral Care, Inc.'s Ready-Fit Disposable Dental Guard - K151149) and a reference device (DenTek Oral Care, Inc.'s Custom Comfort Nightguard Version 2 - K091660) across various characteristics like manufacturer, 510(k) #, device classification, regulation #, product code, regulatory class, description, packaging, design, indications for use, OTC/Rx status, user population, technological characteristics, duration of use, materials, physical properties (tensile strength, elongation, hardness, melt index, density), fit, dimensions, weight, sterilization, and cleaning method.
  • Non-Clinical Performance Testing: This section details "bench testing" and "biocompatibility testing."
    • Bench Testing: An "in-home use test (IHUT)" was conducted to validate the design and performance expectations, specifically verifying reusability. The document references "Section 18: Bench Testing, Attachment 4A: Bench Test Protocol, 4B: Bench Test Engineering Study, and Attachment 4C: Bench Test Data" which are not provided in the given text.
    • Biocompatibility Testing: Four tests were performed according to ISO standards: In-vitro Cytotoxicity (ISO 10993-5:2009(E)), Skin Sensitization (ISO 10993-10:2021(E)), Intracutaneous Reactivity (ISO 10993-23:2021(E)), and Oral Mucosa Irritation (ISO 10993-23:2021(E)). The results indicated the device was non-cytotoxic, non-sensitizer, non-reactive, and non-irritant, respectively.

In summary, the provided document is a regulatory submission for substantial equivalence of a physical dental guard, not a study proving an AI/ML device meets acceptance criteria through a rigorous test set and expert review. Therefore, I cannot extract the specific information requested in your prompt.

Subject Device Description

Protect-It Custom Fit Dental Guard is an over-the-counter device to be used by lay people for protection aqainst the effects of nighttime teeth grinding. It is made of a single thermoplastic resin, ethylene vinyl acetate copolymer, EVA, which is easily molded to the teeth when heated. It is a full-occlusal guard worn on the upper teeth, providing a cushion to separate the upper and lower teeth and keep them apart while sleeping, thus reducing the damage to teeth associated with bruxism.

Indications For Use/Intended Use

The subject device, Protect-It Custom Fit Dental Guard, is an over-the-counter device, indicated for protection against bruxism or nighttime teeth grinding. It is intended to reduce damage to teeth associated with bruxing or nighttime teeth grinding.

The predicate device, DenTek's Ready-Fit Disposable Dental Guard, is an over-thecounter device and has the exact same indication for use and intended use as the subject device. The predicate is indicated for protection for nighttime teeth grinding or bruxism. It is intended to reduce damage to teeth by cushioning them and keeping them apart during grinding.

Technological Characteristics

The subject device, Protect-It Custom Fit Dental Guard is a full occlusal, dental quard made of a single thermoplastic resin, ethylene/vinyl acetate copolymer (EVA), which forms easily to the teeth when heated. By design, it effectively cushions the teeth and keeps them apart during sleep, thus reducing the damage to teeth associate with nighttime teeth grinding. The heat and form process is a commonly used method for fitting full occlusal mouth guards. The referenced device, DenTek's Custom Comfort Dental Guard Version 2 (K091660) is an example of a guard of similar design (shape and size) that is a heat and form dental guard.

The predicate device, DenTek's Ready-Fit Disposable Dental Guard, is a posteriorocclusive mouth-guard, consisting of two bite pads made of a single thermoplastic resin, ethylene/methyl acrylate copolymer (EMA), which are connected by a buccal band that aids in fit and retention. The predicate is a ready to wear, one size fits all design. It has the same intended use as the subject device, to reduce damage to teeth by cushioning them and keeping them apart during nighttime teeth grinding. Thus, the subject device and the predicate device have the exact same technological operating principles. The technological/design differences between Protect-It Custom Fit Dental Guard and the predicate, Ready-Fit Disposable Dental Guard, are minor and do not raise any new questions of safety or effectiveness. Therefore, the subject device is technologically

{5}------------------------------------------------

equivalent to the predicate device. Both the subject device and the predicate device are indicated for over-the-counter use, for age 18 and over.

The table above identifies a few minor differences between the proposed device and the cited predicate and referenced device. 1. The specific durations of use per the products' labeling differ. However, the duration of use does not affect the safety or effectiveness of the subject device. Protect-It Custom Fit Dental Guard was verified to be reusable in a home use simulation (bench test), the report for which is provided in this submission (Section 18: Bench Testing). The longevity of the device will depend on the force of the grinding of the user. No wear guarantee is provided. 2. While the contact material for the subject and predicate devices is a single ethylene-based copolymer, the exact resins are not identical. The subject device uses a similar EVA material as in the moldable layer of the reference device. The appropriateness of the

{8}------------------------------------------------

subject device's resin for use in a dental guard was demonstrated through biocompatibility testing of the finished guard, which is provided in this application. See Section 15: Biocompatibility and Attachments 6-9. Biocompatibility test reports (four tests). 3. The predicate utilizes a ready-to-wear, posterior-occlusion design whereas the subject device, like the reference device, utilizes a full-occlusion design, fit with the heat and form process. All are effective for the intended use. 4. The measurements of the subject device differ from the predicate due to the overall design. The bite radius of the subject device is wider than the predicate because the predicate has a narrow strap between the bite pads that does not retain its in-use shape. The subject is longer as it is designed to be trimmed if needed by the user. Though not identical, the width measurement of the subject device is similar to the cited reference device. 5. The subject device has a higher overall weight due to the full occlusal design versus the posterior-occlusal design of the predicate. The weight of the subject device and the reference device are similar. 6. The subject device and reference device have similar instructions for inspecting and cleaning after each use.

The subject device and the predicate device have the same indications for use and intended use, the same user population and the same technological characteristics.

The minor differences between the subject device and the cited predicate do not raise different questions of safety or effectiveness and this application establishes that the subject device is as safe and effective as the predicate. Thus, the subject device, Protect-It Custom Fit Dental Guard is substantially equivalent to the predicate device, Ready-Fit Disposable Dental Guard. The addition of the reference device comparison presents another substantially equivalent dental guard that is on the market today.

In summary, although they fit the mouth in a slightly different manner, the subject device and the predicate device have the same technological characteristics and intended use, to protect the teeth from the damage of night-time grinding them and keeping them apart.

In accordance with section 513(i)(1)(A) of the FDCA, a device is substantially equivalent (SE) when it has the same intended use and technological characteristics as a legally marketed predicate device. As demonstrated in this traditional 510(k), any differences between the subject device and the cited predicate do not raise different questions of safety or effectiveness and this application establishes that the device is as safe and effective as the predicate.

Non-Clinical Performance Testing

Bench Testing

DOC Brands, Inc. conducted an in-home use test (IHUT) which validated that the design of Protect-It Custom Fit Dental Guard meets the intended use and performance expectations of the device. See Section 18: Bench Testing, Attachment 4A: Bench Test Protocol, 4B: Bench Test Engineering Study, and Attachment 4C: Bench Test Data.

{9}------------------------------------------------

This data supports the subject's substantial equivalence to the predicate.

Biocompatibility Testing

Additionally, the following biocompatibility tests were performed on the subject device.

  • In-vitro Cytotoxicity according to ISO 10993-5:2009(E). Results showed the . tested device, the cited subject device, is non-cytotoxic.
  • Skin Sensitization according to ISO 10993-10:2021(E). Results showed the . tested device, the cited subject device, is a non-sensitizer.
  • Intracutaneous Reactivity according to ISO 10993-23:2021(E). Results showed . the tested device, the cited subject device, was non-reactive under the conditions of the study.
  • Oral Mucosa Irritation according to ISO 10993-23:2021(E). Results showed the ● tested device, the cited subject device, was a non-irritant under the conditions of the study.

These tests further demonstrate the subject device's substantial equivalence to the cleared predicate device.

Conclusion

The Protect-It Custom Fit Dental Guard has the same indications for use and intended use, and the same technological characteristics and principles of operation as the predicate device, Ready-Fit Disposable Dental Guard. The relevant information on biocompatibility and the performance testing, confirm that the Protect-It Custom Fit Dental Guard fulfills its intended use as safely and effectively as the legally marketed predicate device. The Protect-It Custom Fit Dental Guard, the subject device, is therefore substantially equivalent to the predicate device, Ready-Fit Disposable Dental Guard.
