The device is a semi-finished dental blank for creating crowns and bridges, which are restorative devices, not therapeutic devices.
No
This device is a dental blank for fabricating crowns and bridges, which are restorative devices, not diagnostic ones.
No
The device description clearly states it is a semi-finished dental blank made of yttrium stabilized pre-sintered zirconium dioxide, which is a physical material, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for creating dental restorations (crowns, bridges, inlays) for patients. This is a direct application within the body (in vivo), not for testing samples taken from the body (in vitro).
- Device Description: The device is a semi-finished dental blank made of zirconium dioxide, used for milling dental prosthetics. This material is designed to be implanted or placed in the mouth.
- Lack of IVD Characteristics: The description does not mention any components or processes related to analyzing biological samples (blood, urine, tissue, etc.) or providing diagnostic information based on such analysis.
IVD devices are specifically designed to be used in vitro (outside the body) to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device does not fit that description.

Device Description
DD cubeX² is a semi-finished dental blank made of yttrium stabilized pre-sintered zirconium dioxide, which has a super high translucency. The ceramics is of type II (not powder), Class 5 according to DIN EN ISO 6872 (FDA Recognition Number 4-178). The DD cubeX² dental blanks are designed for milled production of crowns and bridge frameworks on commercial CAD/CAM systems or hand-operated copy milling machines. The material is suited ideally for bridges up to 3 elements for both, the anterior and posterior region. The accessories comprises the DD Bio ZX2 monolith zero, which is a coloring fluid for zirconia restorations made from yttrium stabilized pre-sintered zirconium dioxide of different degree of translucency.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Non-clinical testing was performed in order to validate the product against the company's specified design requirements, and to evaluate its safety and effectiveness according to the following standards: EN ISO 10993-1 (biological compatibility) and EN ISO -10993-5 (cytotoxicity) With DD Bio ZX2 monolith zero colored and then sintered DD cubeX2finished products were tested by an accredited testing laboratory with respect to biocompatibility. The laboratory certified that "the insolubility is in compliance with the requirements of the Standard. There is no evidence that effects hazardous to the patient will arise by release of leachable ingredients/contaminants".Based on the test results DD cubeX was classified as eminently suitable for use in the dental applications.

Brief summary
First, DD cubeX2 (modified product) shares de facto all product specifications and characteristics of the predicate device (unmodified device). There is no difference in fundamental scientific technology. Secondly, the modification of the material composition results in a higher translucency of the product, which leads to better aesthetic results. However, it also leads to a lower flexural strength when compared to the unmodified product. This is compensated by restricting the use of DD cubeX2 if used for multi-unit bridges to three element bridges. Finally the Flexural strength testing result of DD cubeX2 (modified product) is considerably higher than required by DIN EN ISO 6872 for class 5 dental ceramics indicated for three element bridges including molar restorations. Thirdly, the two devices are similar in physical and mechanical properties. Also both (for DD cubeX2 (modified product) including coloring fluid accessories) their safety and effectiveness have been verified by appropriate FDA recognized standards.
6
Through they are not identical in chemical material composition, such difference will not influence the core usage of the device, thus will not affect the devices` substantial equivalence.
Discussion of - Clinical Tests Tests Performed Dental Direkt GmbH did not conduct, nor rely upon, clinical tests to determine substantial equivalence as dental ceramics that fall under FDA product code EIH have a long history of safe and effective use in the US. - Non Clinical Tests Non-clinical testing was performed in order to validate the product against the company's specified design requirements, and to evaluate its safety and effectiveness according to the following standards: EN ISO 10993-1 (biological compatibility) and EN ISO -10993-5 (cytotoxicity) With DD Bio ZX2 monolith zero colored and then sintered DD cubeX2finished products were tested by an accredited testing laboratory with respect to biocompatibility. The laboratory certified that "the insolubility is in compliance with the requirements of the Standard. There is no evidence that effects hazardous to the patient will arise by release of leachable ingredients/contaminants".Based on the test results DD cubeX was classified as eminently suitable for use in the dental applications.
