DynaFlex ® EZ-Align® Appliance is a series of up to four, clear, lightweight, plastic retainers intended to be used to correct minor (1.5mm or less to inter canine/cusped crowding) anterior tooth misalignment in patients in permanent dentition by moving teeth progressively to a final, treated state. DynaFlex EZ-Align® is for prescription only.
Device Description
DynaFlex ® EZ-Align® Appliance is a series of up to four, clear, lightweight, plastic retainers intended to be used to correct minor (1.5mm or less to inter canine/cusped crowding) anterior tooth misalignment in patients in permanent dentition by moving teeth progressively to a final, treated state. The device will be custom made for each patient and will be sold by prescription. The device is manufactured with medical grade thermo plastic that is standard throughout the industry. Aligners are fabricated from .030 thermoformed polycarbonate plastic. The mechanism of force application to the teeth is via intentional distortion of the plastic as the aligners are seated in the mouth. Each subsequent aligner in the overall progressive series is made from a mold of the patient's teeth which reflect subtle changes in the position of the teeth from the previous aliener. The positional changes are introduced into each aligner in the laboratory by moving the teeth on the construction model and then forming the aligner on the same model. The overall treatment is prescribed by the dentist to the laboratory where they are fabricated. Aligners may be adjusted by the dentist. Aligners are completely removable by the patient and treatment may be discontinued at any time. The appliance if provided as a non-sterile device and single use.
More Information

Not Found

No
The description details a physical appliance fabricated based on manual manipulation of a model and does not mention any software or algorithms that would suggest AI/ML is used in the design or manufacturing process.

Yes.
The device is intended to correct minor anterior tooth misalignment by moving teeth progressively, which is a therapeutic action.

No

The device is described as an appliance used to correct tooth misalignment by moving teeth progressively, and its intended use is for treatment, not for diagnosing a condition or disease.

No

The device description explicitly states it is a series of clear, lightweight, plastic retainers manufactured from medical grade thermo plastic. This indicates a physical, hardware-based medical device, not a software-only one.

Based on the provided information, the DynaFlex ® EZ-Align® Appliance is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In vitro diagnostics are tests performed on samples taken from the human body, such as blood, urine, or tissue, to detect diseases, conditions, or infections.
  • DynaFlex EZ-Align Function: The DynaFlex EZ-Align appliance is a physical device used directly in the mouth to mechanically move teeth. It does not analyze biological samples or provide diagnostic information about a patient's health status.
  • Intended Use: The intended use clearly states it's for "correcting minor... anterior tooth misalignment," which is a physical manipulation, not a diagnostic process.
  • Device Description: The description details the physical construction and mechanism of action (applying force to teeth), not a method for analyzing biological samples.

Therefore, the DynaFlex EZ-Align Appliance falls under the category of a medical device used for treatment, not an in vitro diagnostic device.

Bench testing of the Aligners has not been performed due to the difficulty in evaluating this type of dental device in a laboratory setting. However, there is sufficient information available from the scientific literature & other legally FDA cleared device of similar characteristics to demonstrate that the preformed tooth positioner provides reasonable assurance of safety and effectiveness. Biocompatibility testing was performed according to ISO 10993 and that all testing passed.

the laboratory where they are fabricated. This technology is essentially identical to that used by a number of sequential alignment systems, including the predicates referenced above.

Performance Characteristics:

Bench testing of the Aligners has not been performed due to the difficulty in evaluating this type of dental device in a laboratory setting. However, there is sufficient information available from the scientific literature & other legally FDA cleared device of similar characteristics to demonstrate that the preformed tooth positioner provides reasonable assurance of safety and effectiveness. Biocompatibility testing was performed according to ISO 10993 and that all testing passed.

Substantial Equivalence:

DynaFlex® EZ-Align® is substantially equivalent to other FDA approved legally marketed orthodontic devices in the United States. EZ-Align® Aligners is used in a manner similar to the Clear Image TM system marketed by Specialty Appliance Works, Inc., and Align Technology Red, White & Blue marketed by Allesee Orthodontic Appliances., and Clear Correct marketed by Clear Correct, Inc. The proposed and predicate devices are of similar design; made from virtually identical materials, and are fabricated using similar manufacturing methods that are common to the dental device industry. Furthermore, DynaFlex® EZ-Align® Appliance have the same intended uses as the predicate devices in that they serve as an oral appliance constructed of polymer components that when fabricated into their final form and dimensions, are a dental appliance that are custom fit for the patient. The properties and characteristics of the predicate devices are compared to DynaFlex® EZ-Align® Devices in the Table 12-1.

Dear Mr. Malabey:

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. 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.
