Indications for Use
The SmileAlign® Orthodontic Aligner System is indicated for the treatment of tooth malocclusion in patients with permanent dentition (i.e., all second molars). The SmileAlign Orthodontic Aligner System positions teeth by way of continuous gentle force.
Device Story
SmileAlign Orthodontic Aligner System consists of series of clear, thin thermoformed PETG plastic aligners; designed to progressively reposition teeth via continuous gentle force. Dental practitioner uses 3Shape Ortho System software to generate/review model schemes; practitioner approves treatment plan before fabrication. Patient wears aligners sequentially, typically replacing every 2 weeks as prescribed. Device used in clinical setting under professional supervision. Benefits include correction of malocclusion through programmed tooth displacement.
Clinical Evidence
No clinical data included. Bench testing only: biocompatibility (ISO 10993-5 cytotoxicity, ISO 10993-10 irritation/sensitization) and material properties (tensile strength, compression strength, water absorption, density, pH change) passed.
Technological Characteristics
Material: PETG (thermoplastic polymer). Form factor: clear, thin thermoformed aligners. Principle: continuous gentle force via sequential programmed displacement. Software: 3Shape Ortho System used for modeling/planning. Biocompatibility: ISO 10993 compliant.
Indications for Use
Indicated for treatment of tooth malocclusion in patients with permanent dentition (all second molars).

Dear Diana Lam:
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.

The SmileAlign® Orthodontic Aligner System is substantially equivalent to the predicate device. Both the subject and predicate devices use independent dental software to translate tooth movements in developing the model schemes and allow the dental practitioner to review and approve the model schemes before aligner fabrication. The difference between the subject and predicate device lies in the difference in manufacturer, where the risks have been mitigated by biocompatibility evaluation and material testing. SmileAlign® Orthodontic Aligner System uses 3Shape Ortho System™ (K152086), the reference predicate, as the software for dental professionals to generate and review model schemes.
#### Non-Clinical performance Data
Different biocompatibility tests in accordance with ISO10993 have been performed on the subject device. The results of these tests and studies indicate there is no evidence of any hazardous effects and the subject device is safe for its intended use.
| Test Name | Standard followed | Result |
|---------------|-------------------|--------|
| Cytotoxicity | ISO10993-5 | Pass |
| Irritation | ISO10993-10 | Pass |
| Sensitization | ISO10993-10 | Pass |
Material properties, such as tensile strength, compression strength, water absorption rate, density and pH change were tested, all results provided reasonable assurance of safety and effectiveness.
