6MS Invisible Aligner is indicated for the alignment of teeth during orthodontic treatment of malocclusion in patients with permanent dentition (i.e. all second molars). The 6MS Invisible Aligner positions teeth by way of continuous gentle force.
6MS Invisible Aligner consists of a series of dental-clinician prescribed customized clear plastic removable orthodontic aligner trays that are made from a clear, thin thermoformed polyurethane-polyester composite. The aligners are designed to gradually move the patient's teeth incrementally, repositioning them from their original misalignment to a more aligned state. This occurs through forces applied by the appliance to the teeth over time until final correction, according to the dental clinician's prescription has been achieved. A dental clinician prescribes the 6MS Invisible Aligner based on an evaluation of the patient's teeth. Either intraoral scans or physical impressions of the patient's teeth are taken, after which the clinician determine course of treatment with the system. The clinician completes a prescription form using standard dental software used for tooth alignment. The series of plastic aligner trays are designed according to commercially available dental software for planning the tooth alignments. After the digital plan is developed and approved by the prescribing dental clinician, SMS OPCO produces the aligner trays. The customized aligner trays are then provided to the dental clinician who distributes them to the patient assuring fit and function.
The provided text is a 510(k) Summary for a medical device (6MS Invisible Aligner). It describes the device, its intended use, and lays out a comparison to a predicate device to demonstrate substantial equivalence. However, it does not contain information about an AI/Algorithm-powered device or a study involving human readers or AI assistance.
Therefore, I cannot fulfill your request for information related to "acceptance criteria and the study that proves the device meets the acceptance criteria" in the context of an AI-powered device, MRMC studies, or standalone algorithm performance, as these concepts are not discussed in the provided document.
The "Device Testing Non-clinical Testing" section (Page 6) details conventional non-clinical tests for mechanical properties, packaging, and manufacturing process validation. It also mentions biocompatibility testing. The "Clinical Testing" section explicitly states that "Neither animal nor human testing are required for this product" because of its substantial equivalence to the predicate device in terms of materials, design, and manufacturing method.
In summary, the provided document does not support a response to your specific questions about AI/algorithm performance or MRMC studies.

Dear Patsy Trisler:
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. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. 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.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part
{1}------------------------------------------------
801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).

Device Testing Non-clinical Testing
Test data were submitted to:
- . assure the mechanical properties of the aligner material meet specifications for up to 5 years shelf life [according to ASTM D638 standard's testing for: tensile strength (PSI): elongation (%), tensile@ yield (PSI), elongation @ yield (PSI) and tensile modulus (PSI)];
- . assure the aligner material packaging retains the required moisture barrier properties;
- . validate the processes used for the design and manufacture of the customized aligners, to ensure consistency between the aligner's design and the manufactured aligners.
All testing met the pre-determined acceptance criteria.
Biocompatibilitv
The thermoplastic polyurethane used for making the aligner series has been tested according to Good Laboratory Practices for its biocompatibility according to ISO 10993, as follows:
- Part 5 (Cytotoxicity Elution MEM),
- Part 10 (Intracutaneous/Intradermal Reactivity).
- Part 10 (Oral Mucosa Irritation),
- Part 10 (Maximization for Delayed-Type Hypersensitivity)
In addition, the finished customized aligner was tested according to ISO 10993, Part 5, Cytotoxicity. Results show it is noncytotoxic. All testing showed that the thermoplastic material and the manufactured finished aligner met the requirements of the test methods and are safe and biocompatible for the stated intended use.
Clinical Testing
Neither animal nor human testing are required for this product because it is composed of the same materials, is designed similarly, and is manufactured by a similar method as the predicate device.
- Conclusion The conclusions drawn from the nonclinical tests demonstrate that the subject device is as safe and effective as the legally marketed device, K182826.
