Indications for Use

The CREOKORREKT Aligner is indicated for the treatment of tooth malocclusion in patients with permanent dentition (i.e. all second molars). The aligner positions teeth by way of continuous gentle force.

Device Story

CREOKORREKT Aligners are custom-made, clear, thermoformed polyurethane and copolyester orthodontic appliances. Input: intraoral scans or PVS impressions of patient dentition. Process: dentist prescribes treatment; CreoDent Prosthetics imports scans into dental design software (Ortho System or Autolign) to plan sequential tooth movement; software generates series of models; models 3D printed; aligners thermoformed over models. Output: series of removable clear plastic trays. Use: clinic; prescribed by dentist; worn by patient. Benefit: alternative to conventional wire/bracket orthodontics; provides gentle continuous force to move teeth to planned positions.

Clinical Evidence

Bench testing only. Includes physical properties testing (ASTM D638, D790, D570, D5420) and biocompatibility testing (ISO 10993-3, 5, 10, 11). Manufacturing process validation confirmed the aligners meet pre-established acceptance criteria for fit, form, and function.

Technological Characteristics

Materials: Zendura A (polyurethane) or Zendura FLX (copolyester/polyurethane composite), 0.76mm thickness. Principle: thermoformed plastic trays applying continuous force. Connectivity: N/A (custom-fabricated). Software: dental design software (Ortho System, Autolign). Standards: ASTM D638, D790, D570, D5420; ISO 10993.

Indications for Use

Indicated for treatment of tooth malocclusion in patients with permanent dentition (all second molars).

Regulatory Classification

## Predicate Devices:

Primary Predicate K192846, Argen Clear Aligner by Argen Corporation

Reference Device K192596, uLab Systems Dental aligner by uLab Systems Inc.

## Indication for Use:

The CREOKORREKT Aligner is indicated for the treatment of tooth malocclusion in patients with permanent dentition (i.e. all second molars). The aligner positions teeth by way of continuous gentle force.

## Device Description:

CREOKORREKT Aligners consist of a series of dentist-prescribed, thin, clear, thermoformed polyurethane and copolyester orthodontic appliances. The aligners provide gentle continuous force to move the patient's teeth in small increments from their original positions to planned positions. CREOKORREKT Aligners are intended as an alternative to conventional wire and bracket orthodontic technology and fixed appliances for the treatment of patients with tooth malocclusion.

A dentist determines a treatment plan based on the assessment of the patient's teeth and prescribes the CREOKORREKT. To obtain the dimensions and details of a patient's dentition, a dentist takes intraoral

{4}------------------------------------------------

scanning or a physical impression (PVS Impression) and sends them with a prescription to CreoDent Prosthetics LTD.

With PVS impressions, physical models are fabricated and scanned. Scanned data are directly imported into dental design software for planning. CreoDent Prosthetics LTD designs the process of treatment by creating a series of the sequential model intended to gradually move the patient's teeth to the desired position in accordance with the dentist's prescription utilizing the dental design software. The doctor reviews and approves the treatment scheme. CreoDent Prosthetics LTD fabricates a series of models for thermoforming.

## SE Discussion

The subject device and primary predicate, K192846 have same indications for Use, mode of action, description of use, thermoformed copolyester and polyurethane composite material (Zendura FLX), manufacturing process (i.e., Scanning, Treatment planning, Thermoforming, etc.), thickness of material, color of material, and treatment planning software.

The differences between the subject device and primary predicate are the material (Zendura A) and using software (Autolign: Diorco). To support the discrepancy of the different material, K192596 was added as the reference device for the substantial equivalence.

Zendura FLX and Zendura A have been produced in only one film format for each. The film is 0.76mm in thickness. Bay Materials, LLC supplies sheets in different widths and lengths or diameters but all of these are cut from the same film. Therefore, the material of the subject device is identical to that of the predicate devices.

To support the discrepancy of the different software used, a manufacturing process validation test was performed and it showed that no significant differences were found between the designs using Autolign (Diorco, K192847) and Ortho Analyzer (3shape, K180941)

#### Non-Clinical Testing

Non-clinical testing data are submitted to demonstrate substantial equivalence.

- Physical properties testing of the material (Zendura A) according to ASTM D6387, ASTM D790, ASTM D570 and ASTM D5420
- Biocompatibility Testing of the material (Zendura FLX and Zendura A) according to ISO 10993-3,5,10, and 11

#### Manufacturing Process Validation Testing

This test was conducted to validate the manufacturing process of the final product. It evaluated the fit, form, and function of the final product by a trained physician as compared to software treatment design. This test has met the pre-established acceptance criteria. The test results showed that the manufacturing process of the subject aligner achieves its intended use, and it is substantially equivalent to the predicate devices.

#### Conclusion

In accordance with the Federal Food, Drug and Cosmetic Act, 21 CFR Part 807, and based on the information provided in this premarket notification, CreoDent Prosthetics LTD concludes that the CREOKORREKT aligner is substantially equivalent to the predicate devices as herein.
