The Rest Assured Ready to Wear Nite Protector is indicated for use for protection against bruxism or nighttime teeth grinding. The device is intended to reduce damage to the teeth and to prevent the noise associated with bruxing or grinding.

Device Description

The Rest Assured Ready to Wear Nite Protector is a posterior-occlusive nightguard, comprised of two molar bite pads connected by a buccal retaining strap. The device is fit to the user's mouth by adjusting the bite plates along the retaining strap.

AI/ML Overview

Here's a breakdown of the acceptance criteria and study information for the Ranir, LLC's Rest Assured Ready to Wear Nite Protector, based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

Acceptance Criteria	Reported Device Performance
Biocompatibility (ISO 7405)	Met. "ISO 7405 was adhered to in the evaluation of biocompatibility of device materials." No specific performance metrics are given, but compliance with the standard implies acceptable biocompatibility.
Wear Resistance (Alabama-type wear testing)	"Wear resistance of the evaluated night guard material was comparable to the tested predicate devices with no abnormal evaluations."
Comparability to Predicate Device (with similar design)	"The third party laboratory verified that the subject device is comparable to the predicate device and can be used on the mandibular or maxillary teeth with the adjustable bite plates similar to the predicate device design."
Effectiveness of Labeling for Device Use	Met. "Greater than 80% of the tested subjects agreed that the adjustable bite pads were acceptable and 95% of the subjects approved of the overall fitting process and fit their device correctly."

2. Sample Size Used for the Test Set and Data Provenance

Sample Size: 20 subjects were used for the user study.
Data Provenance: The document does not specify the country of origin. It is a prospective user study conducted to verify labeling effectiveness.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

There were no external experts used to establish ground truth in the user study. The "ground truth" for the user study was based on the subjects' own successful fitting of the device and their agreement/approval of the product features and fitting process.

4. Adjudication Method for the Test Set

No formal adjudication method (like 2+1, 3+1) was used as the "ground truth" was derived directly from the subjects' experience and their self-assessment of successful fitting and satisfaction with the bite pads and fitting process.

5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study Was Done

No, an MRMC comparative effectiveness study was not done. The studies described are bench tests and a user study focusing on device fit and labeling comprehension.

6. If a Standalone (i.e. algorithm only without human-in-the loop performance) Was Done

This question is not applicable. The device is a physical night guard, not a software algorithm. Therefore, "standalone" performance in the context of an algorithm is not relevant.

7. The Type of Ground Truth Used

Biocompatibility: Compliance with ISO 7405 (a standard).
Wear Resistance: Comparison to predicate devices, presumably against established wear characteristics of those devices.
Comparability: Verification by a third-party lab against a predicate device with similar design.
User Study: Subjective user feedback on acceptability of adjustable bite pads and approval of the overall fitting process/correct fit.

8. The Sample Size for the Training Set

This question is not applicable. The device is a physical night guard, and there is no mention of machine learning or an "algorithm" requiring a training set.

9. How the Ground Truth for the Training Set Was Established

This question is not applicable, as there is no training set for an algorithm mentioned.

{1}------------------------------------------------

Purpose of the Special 510(k) notice

The Rest Assured Ready to Wear Nite Protector is a modification to Ranir's Rest Assured Night Generation II Dental Protector (K091792).

Notably, the Rest Assured Ready to Wear is the same device as the Rest Assured II. with five minor differences: (1) the Rest Assured Ready to Wear is a posterior, occlusive mouthguard, whereas the Rest Assured II is a fully occlusive mouthguard; (2) the Rest Assured Ready to Wear is to be worn on either the mandibular or maxillary teeth, while the Rest Assured II is for maxillary teeth only: (3) while the Rest Assured II is fitted using the "boil and bite" technique, the Rest Assured Ready to Wear is fitted via adjustable bite plates without boiling; (4) the Rest Assured Ready to Wear is made of ELVALOY, ELVAX, and polypropylene, while the Rest Assured II is made from ELVAX and Dynaflex; and (5) labeling modifications to provide appropriate user fitting instructions.

Intended Use

Technological Characteristics

Substantial Equivalence

The company's Rest Assured Ready to Wear has the same intended use and indications for use as the previously cleared predicate devices, the Rest Assured II, the Grind No More 2, and the SleepRight. In addition, the Rest Assured Ready to Wear has similar technological characteristics and principles of operation to the Rest Assured II, the Grind No More 2, and the SleepRight. Although there are minor differences between the Rest Assured Ready to Wear and the Rest Assured II, namely in the use of the device on the posterior portion of the mandible only, the change in the design and function of the adjustable bite plates, the change in materials, and the limited labeling changes, these minor differences do not raise new questions of safety or efficacy. The posterior-only occlusial design and use of the device on mandibular teeth are common to other cleared mouthguards, such as the previously cleared SleepRight and Grind No More 2 devices. The adjustable nature of the device is also supported by the SleepRight predicate. Although the materials used in the device have changed, each of the materials comprising the Rest Assured Ready to Wear are common to other cleared medical devices, including the named predicates. Finally, the limited labeling changes only provide appropriate instructions on how to fit the device properly and do not affect device safety or

effectiveness. Thus. the Rest Assured Ready to Wear is substantially equivalent to the claimed predicate devices.

Performance Testing

A risk analysis for the subject device was performed per ISO 14971 and ISO 7405 was adhered to in the evaluation of biocompatibility of device materials.

In addition, the company performed wear testing on the subject device to evaluate the wear resistance (i.e., Alabama-tvpe wear testing) of the device in comparison to various over-the-counter FDA-cleared predicate night guards. The wear resistance of the evaluated night guard material was comparable to the tested predicate devices with no abnormal evaluations.

Next, a third party testing laboratory tested the device to establish that the subject device was comparable to an identified predicate device with similar design. The third party laboratory verified that the subject device is comparable to the predicate device and can be used on the mandibular or maxillary teeth with the adjustable bite plates similar to the predicate device design.

Lastly, a 20 subject user study was conducted to verify that the limited labeling changes for device use were effective and well understood by the 20 subjects. Greater than 80% of the tested subjects agreed that the adjustable bite pads were acceptable and 95% of the subjects approved of the overall fitting process and fit their device correctly.

In sum, the above summarized bench testing and user study results confirm that the Rest Assured Ready to Wear is substantially equivalent to the claimed predicate devices in intended use, device design, safety and effectiveness.
