Intended Use

PEEK Biosolution is intended to be used for the fabrication of permanent dental restorations using CAD/CAM techniques. These are: - Fully anatomical crowns and bridges (max. 2 pontics and min. 13 mm2 connector cross-section) - Crown copings and bridge substructures for composite veneering (max. 2 pontics and min. 13 mm2 connector cross-section)) - Telescopic primary and secondary crowns and frameworks - Secondary bar structures on primary bars made of titanium alloy, CoCr alloys, gold alloy, zirconium dioxide.

Device Story

PEEK Biosolution is a polyetheretherketone (PEEK) milling disc used by dental laboratories to fabricate permanent dental restorations via CAD/CAM systems. The device serves as raw material; dental technicians use CAD/CAM software and milling equipment to shape the disc into specific dental prosthetics. The resulting restorations are used for crowns, bridges, telescopic frameworks, and secondary bar structures. The device provides a biocompatible, high-strength alternative to traditional dental materials, benefiting patients by enabling durable, custom-fitted restorations.

Clinical Evidence

Bench testing only. No clinical data. Testing included melting temperature (ISO 11357), water sorption (ISO 62), bond strength (ISO 10477), density (ISO 1183), modulus of elasticity (ISO 20795-1), and flexural strength (ISO 10477). Biocompatibility testing performed per ISO 10993-1 and USP Class VI.

Technological Characteristics

Material: Polyetheretherketone (PEEK) plus pigments. Form: Solid disc with circumferential ridge. Dimensions: 95 mm diameter; 12-30 mm thickness. Fabrication: CAD/CAM milling. Standards: ISO 11357, ISO 62, ISO 10477, ISO 1183, ISO 20795-1, ISO 10993-1, USP Class VI.

Indications for Use

Indicated for patients requiring permanent dental restorations, including fully anatomical crowns and bridges, crown copings, bridge substructures for veneering, telescopic crowns/frameworks, and secondary bar structures.

Dear Richard Hunter:

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.

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 of medical device-related adverse events) (21 CFR 803); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820);

{1}------------------------------------------------

and if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.

Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97). For questions regarding the reporting of adverse events under the MDR regulation (21 CFR Part 803), please go to http://www.fda.gov/MedicalDevices/Safety/ReportaProblem/default.htm for the CDRH's Office of Surveillance and Biometrics/Division of Postmarket Surveillance.

For comprehensive regulatory information about mediation-emitting products, including information about labeling regulations, please see Device Advice (https://www.fda.gov/MedicalDevices/DeviceRegulationandGuidance/) and CDRH Learn (http://www.fda.gov/Training/CDRHLearn). Additionally, you may contact the Division of Industry and Consumer Education (DICE) to ask a question about a specific regulatory topic.

Physical Properties of PEEK Biosolution and breCAM.BioHPP

PEEK raw material (granules) used in the production of rod stock was tested by the manufacturer according to ISO 10993-1 and USP Class VI and found to be biocompatible. PEEK Biosolution, which is manufactured from the rod stock, was tested and found to not release extractable inorganic substances, and was not cytotoxic. All tests were performed according to GLP requirements.

# Summary:

Based on the above description of the Merz Dental GmbH PEEK Biosolution and the predicate device. Merz Dental considers PEEK Biosolution to be substantially equivalent to the cited predicate device, and safe and effective for its intended use.
