• Attributes: Therapeutic

Intended Use

Pekkton® Ivory is intended for use with fixed (crowns and bridges) and removable dental prostheses.

Device Story

Pekkton® Ivory is a semi-crystalline thermoplastic (PEKK) supplied as milling or press blanks. Dental technicians use CAD/CAM milling or heat/pressure melt processing to fabricate permanent dental prostheses, including crowns, bridges, and removable frameworks. The device serves as a structural material for dental restorations. By providing a durable, biocompatible framework, it enables the restoration of tooth function and aesthetics. The final prosthesis is placed by a dentist. The material's mechanical properties, such as flexural strength and E-modulus, support its use in long-term dental applications.

Clinical Evidence

Bench testing only. No clinical data. Testing included biocompatibility (cytotoxicity, irritation, sensitization, systemic toxicity, implantation, genotoxicity per ISO 10993), chemical characterization, and physical/mechanical performance (flexural strength per ASTM D790, E-modulus per ASTM D638, water absorption/solubility per ISO 4049, and bond strength to veneering resins). Static fracture load and fatigue tests were conducted to confirm performance equivalence to the predicate.

Technological Characteristics

Material: PEKK (Polyetherketoneketone) with Titanium Dioxide. Form: Milling blanks and press blanks. Processing: CAD/CAM milling or heat/pressure melt processing. Melting temperature: ~363°C. Mechanical properties: Flexural strength 200 MPa (ASTM D790), E-modulus ~5000 MPa (ASTM D638). Biocompatibility: ISO 10993 compliant. Connectivity: None (material).

Indications for Use

Indicated for definitive supported and veneered crowns and bridges with maximum two pontics; definitive supported, veneered single crowns and bridges with maximum one pontic on natural teeth; and removable restorations such as secondary structures on bars and telescopic crowns, transversal connectors, occlusal splints, and denture bases.

Regulatory Classification

Identification

Tooth shade resin material is a device composed of materials such as bisphenol-A glycidyl methacrylate (Bis-GMA) intended to restore carious lesions or structural defects in teeth.

Dear Uli DIERMANN:

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.

## Summary of Testing to Demonstrate Substantial Equivalence / Conclusion:

For the risk assessment of biological risks, the procedures and provisions of ISO 10993-1:2009 "Biological Evaluation of Medical Devices – Part 1: Evaluation and Testing within a Risk Management Process", recognition number 2-156, were applied. Based upon the criteria set out in this standard, the product is biologically classified as an "external communicating device" with "permanent" (> 30 days) contact to "tissue, bone or dentine".

In accordance with the aforementioned standards, in accordance with ISO 7405:2008 Dentistry evaluation of biocompatibility of medical devices used in dentistry including: amendment 1 (2013), recognition number 4-212 and in accordance with "510(k) Memorandum - #G95-1 Attachment B – Table 2 Supplementary Evaluation Tests for Consideration", the following test methods were particularly considered, conducted and passed the criteria:

Table 5-2

The subject device Pekkton® Ivory (K170102 ) is identical to the reference device Pekkton® Ivory (K123638). No incidents or adverse events have been reported since the market launch of Pekkton® lvory (K123638).

Non-clinical test data was used to support the substantially equivalence claim. Non-clinical testing consisted of analysis of devices to identify worst-case test samples. The evaluation was based on FDA guidance "Guidance for Industry and FDA Staff, Dental Composite Resin Devices - Premarket Notification (510(k)) Submissions."

Chemical-, physical properties, and bond strength to veneering composites have been evaluated. Static fracture load and fatigue tests as well as simulated use tests have been conducted to evaluate the performance characteristics of Pekkton® Ivory. The test methods were based on established standards and quidelines. Testing has shown that Pekkton® Ivory is equivalent in performance characteristics to the predicate device BioHPP. The acceptance criteria were met.

The summary of application and functional testing indicate that the device is substantially equivalent to the predicate device.
