TECNO MED MINERAL, TECNO MED MINERAL DENTINE and TECNO MED MINERAL TISSUE are used to create reduced crowns and bridges (max. 2 pontics and min. 13 mm² connection cross-section), telescopic primary crowns, copings as well as frameworks for composite veneered bridges. The width of the bridge must not exceed two pontics for reasons of stability.

TECNO MED is designed for the manufacturing of frictional elements on telescopic restorations or attachments.

Device Description

Tecno Med and the three Tecno Med Mineral devices are tooth-shade polymer discs based on polyether ether ketone (PEEK). These discs are available in a variety of shapes for different milling systems. For each device, there are two diameter variants, 95 mm and 98 mm. The discs with a diameter of 98 mm are additionally available with or without step. Moreover, each model is provided in different heights (8mm-30 mm). The users can choose according to their requirements and preferences among the different models. Tecno Med Mineral, Tecno Med Mineral Dentine as well as Tecno Med Mineral Tissue have the same indications for use, for the Tecno Med device there are other indications for use.

These polymer discs are used by specifically trained personnel using CAD/CAM techniques.

AI/ML Overview

The provided text is a 510(k) summary for dental resin materials (Tecno Med Mineral, Tecno Med Mineral Dentine, Tecno Med Mineral Tissue). It does not describe an AI/ML medical device. Therefore, I cannot extract information related to acceptance criteria, study methods, ground truth establishment, or sample sizes as they pertain to AI/ML device performance.

The document focuses on demonstrating substantial equivalence to a predicate device (breCAM.BioHPP) through non-clinical performance testing of physical properties such as water absorption, water solubility, density, modulus of elasticity, flexural strength, and biocompatibility, as well as similarities in chemical composition, indications for use, and intended user.

Dear Mark Job:

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.

The width of the bridge must not exceed two pontics for reasons of stability.

Technological Characteristics and substantial equivalence

Chemical composition:

The new devices as well as the predicate devices are based on PEEK, therefore they are similar in their chemical composition.

Indications for use:

The indications for use of the new and predicate devices are similar.

Intended user:

The subject devices as well as the predicate devices are intended to be further processed by specifically trained personnel.

The logo is composed of two words, "Zirkon" and "zahn", with the first word in white letters and the second word in white letters on a black background. Below the logo is the tagline "Human Zirconium Technology" in a smaller font.

Non-clinical performance:

Non clinical testing was performed to determine the physical properties of the subject devices. In consideration of the International Standard ISO 10993-1, Biological Evaluation of Medical Devices, Part 1: Evaluation and Testing, the subject devices were tested to evaluate: In-vitro cytotoxicity, Skin sensitization, Irritation, Mutagenicity. Biocompatibility testing demonstrated that no issue of biocompatibility arises. Furthermore, on the subject devices testing according to ISO 10477:2004 and DIN EN ISO 20795-2:2013 were performed. All test samples meet the requirements set by the standards.

The results of nonclinical tests demonstrate that the devices are equivalent to the predicate device.

Image /page/6/Picture/1 description: The image shows the logo for Zirkonzahn. The logo is in black and white, with the word "Zirkonzahn" in a bold, sans-serif font. Below the logo is the text "Human Zirconium Technology" in a smaller, serif font. The logo is simple and modern, and it conveys a sense of quality and innovation.

The Zirkonzahn devices as well as the breCAM.BioHPP device are available as milling blanks. These blanks can be obtained in different shapes for different milling systems, different heights and different dental shades. Zirkonzahn provides a broader range of color shades as Bredent. This difference results from the fact that Zirkonzahn wants to provide to the customer a broader range of options. The specifically trained staff may choose among them, according to the aesthetic requirements.

The subject device and the predicate device meet the requirements of the applicable ISO standards and show similar results.

The test data shown above indicate that the subject devices are substantially equivalent to the predicate device.

Conclusion

The new devices of Zirkonzahn srl are substantially equivalent to the cleared predicate device as they are similar in their indications for use, material, technology, design and performance specifications.
