Intended Use

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.

Device Story

6MS Invisible Aligner consists of customized, clear, removable thermoplastic polyurethane-polyester composite orthodontic trays. Input: intraoral scans or physical impressions of patient teeth. Process: dental clinician uses commercial dental software to plan tooth movement; digital plan approved by clinician; SMS OPCO manufactures trays via thermoforming on molds. Output: series of sequential aligner trays. Usage: clinician-prescribed; patient wears trays incrementally to apply continuous gentle force to teeth, repositioning them from misalignment to aligned state. Benefit: gradual, incremental orthodontic correction of malocclusion.

Clinical Evidence

No clinical data. Bench testing only. Non-clinical testing included mechanical property verification (ASTM D638: tensile strength, elongation, tensile modulus) for 5-year shelf life, packaging moisture barrier validation, and process validation. Biocompatibility testing performed per ISO 10993-1, -5, and -10 (cytotoxicity, sensitization, irritation, intracutaneous reactivity).

Technological Characteristics

Material: thermoplastic polyurethane-polyester composite. Form factor: customized thermoformed clear aligner trays. Manufacturing: thermoforming on molds. Connectivity: uses commercial dental software (3Shape K180981, NemoCast K193003) for design. Biocompatibility: ISO 10993 compliant. Non-sterile packaging.

Indications for Use

Indicated for alignment of teeth during orthodontic treatment of malocclusion in patients with permanent dentition (all second molars).

Regulatory Classification

Identification

# Substantial Equivalence Comparison Table

{6}------------------------------------------------

#### 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.
