Indications for Use

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 Story

DynaFlex EZ-Align is a series of up to four custom-made, clear, thermoformed polycarbonate plastic retainers. The device is prescribed by a dentist or orthodontist who takes patient tooth molds and submits them to the laboratory. The laboratory creates a series of models with incremental tooth position changes; aligners are then thermoformed over these models. The device functions by applying gentle, continuous force to teeth through intentional distortion of the plastic when seated in the mouth. It is intended for minor anterior tooth misalignment. The aligners are removable by the patient and worn as directed by the clinician. The system provides a progressive treatment path to a final, treated state. It is a non-sterile, single-patient-use device.

Clinical Evidence

No clinical data provided. Bench testing was not performed due to the nature of the dental device; safety and effectiveness are supported by scientific literature and substantial equivalence to legally marketed predicate devices. Biocompatibility testing was performed and passed according to ISO 10993.

Technological Characteristics

Materials: .030 thermoformed polycarbonate plastic. Mechanism: Sequential force application via intentional plastic distortion. Form factor: Series of up to four custom-fit clear aligners. Connectivity: None. Sterilization: Non-sterile. Software: None.

Indications for Use

Indicated for patients with permanent dentition requiring correction of minor anterior tooth misalignment (1.5mm or less inter-canine/cusped crowding).

Regulatory Classification

Identification

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. # Statement of Intended Use: 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. #### Summary of Technological Characteristics: Section 5.0: 510(k) Summary Submitter: DynaFlex® EZ-Align® Premarket Notification: Traditional 510(k): A dental health care professional (e.g. Orthodontist or Technological dentist), prescribes the EZ-Align® system based on an characteristics assessment of the patient's teeth, determines a course of treatment with the system, takes molds of the patient's teeth, and completes a prescription form The molds and prescription are sent to Dynaflex designs a series of plastic trays intended to gradually realign the patient's teeth in accordance with the physician's prescription. DynaFlex produces the trays, which are fabricated from .030 thermoformed polycarbonate plastic.

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.
