Primeprint Aligner is a light curing resin intended for the treatment of tooth malocclusion in patients with developed permanent dentition. Primeprint Aligner repositions teeth by way of continuous gentle force. Intended place of use: Orthodontic/dental practices/clinics, dental laboratories

Device Story

Primeprint Direct Aligner is a light-curing urethanacrylate resin used to produce dental aligners via 3D printing. The device is processed using the Primeprint Solution (385nm DLP 3D printer and post-processing unit). It is intended for use by dental professionals in clinics or laboratories to treat tooth malocclusion in patients with permanent dentition. The final aligner is a removable appliance worn by the patient to reposition teeth through continuous gentle force. The workflow involves software for ordering and manufacturing. The device benefits patients by providing a custom-fitted orthodontic solution for tooth alignment.

Clinical Evidence

Bench testing only. No human clinical testing performed. Performance evaluated per ISO 20795-2:2013 (curing, color, porosity, flexural strength, fracture work, stress intensity, modulus, sorption, solubility) and biocompatibility per ISO 10993 series (cytotoxicity, sensitization, irritation, systemic toxicity, genotoxicity).

Technological Characteristics

Light-curing urethanacrylate resin containing methacrylate. Form: liquid, non-sterile. Manufacturing: UV-light cured 3D printing (DLP). Standards: ISO 20795-2 (orthodontic base polymers), ISO 10993 (biocompatibility). Connectivity: software-based ordering workflow.

Indications for Use

Dear Anke Hüttenbrauck:

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 (the 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 available 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. 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.

Additional information about changes that may require a new premarket notification are provided in the FDA guidance documents entitled "Deciding When to Submit a 510(k) for a Change to an Existing Device" (https://www.fda.gov/media/99812/download) and "Deciding When to Submit a 510(k) for a Software Change to an Existing Device" (https://www.fda.gov/media/99785/download).

Your device is also subject to, among other requirements, the Quality System (QS) regulation (21 CFR Part 820), which includes, but is not limited to, 21 CFR 820.30, Design controls; 21 CFR 820.90, Nonconforming product; and 21 CFR 820.100, Corrective and preventive action. Please note that regardless of whether a change requires premarket review, the QS regulation requires device manufacturers to review and approve changes to device design and production (21 CFR 820.30 and 21 CFR 820.70) and document changes and approvals in the device master record (21 CFR 820.181).

Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting (reporting of medical device-related adverse events) (21 CFR Part 803) for devices or postmarketing safety reporting (21 CFR Part 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reporting-combination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR Part 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR Parts 1000-1050.

All medical devices, including Class I and unclassified devices and combination product device constituent parts are required to be in compliance with the final Unique Device Identification System rule ("UDI Rule"). The UDI Rule requires, among other things, that a device bear a unique device identifier (UDI) on its label and package (21 CFR 801.20(a)) unless an exception or alternative applies (21 CFR 801.20(b)) and that the dates on the device label be formatted in accordance with 21 CFR 801.18. The UDI Rule (21 CFR 830.300(a) and 830.320(b)) also requires that certain information be submitted to the Global Unique Device Identification Database (GUDID) (21 CFR Part 830 Subpart E). For additional information on these requirements, please see the UDI System webpage at https://www.fda.gov/medical-devices/device-advice-comprehensive-regulatory-assistance/unique-device-identification-system-udi-system.

Dreve Dentamid GmbH
Primeprint Direct Aligner
Traditional 510(k)

The following differences exist between the subject and the predicate device:

In the chemical composition/characterization and the manufacturing process differences exist. Primeprint Direct Aligner is made of urethanacrylate resin consisting of methacrylate whereas the Predicate is a polyurethane resin which is not the same, but it is equivalent.

Both materials are using a 3D printer with UV cured 3D printing resins and the method of manufacturing is the same. There are slight differences in the printers and curing systems being used but the reference device uses the same 3D printing and curing solution. Furthermore, the performance tests show that Primeprint Direct Aligner meets its safety and effectiveness criteria same as the predicate device.

# NON-CLINICAL PERFORMANCE TESTING

Primeprint Direct Aligner has been tested and meets the requirements of the following FDA Recognized Consensus Standard:

- ISO 20795-2:2013 - Dentistry – Base polymers – Part 2: Orthodontic base polymers

Performance testing was performed on the subject device according to ISO 20795-2 standard for curing, color, porosity, ultimate flexural strength, total fracture work, maximum stress intensity factor, flexural modulus, sorption and solubility endpoints identified in ISO 20795-2.

The subject and the predicate device were tested to ISO 20795-2 standard meeting most of the requirements. The results for ultimate flexural strength and flexural modulus demonstrated similar performance of the properties.

For the evaluation of the biological safety of the subject device ISO 10993-1:2018 Biological evaluation of medical devices - Part 1: Evaluation and testing within a risk management process and ISO 7405:2018 Dentistry - Evaluation of biocompatibility of medical devices used in dentistry were considered. Biocompatibility testing was performed according to the standards cited in the following paragraph.

The non-clinical performance testing meets the acceptance criteria and demonstrates that Primeprint Direct Aligner meets the requirements for its intended use.

# BIOCOMPATIBILITY

Primeprint Direct Aligner meets the biocompatibility requirements of the following standards:

- ISO 10993-1:2018 - Biological evaluation of medical devices – Part 1: Evaluation and testing within a risk management process
