Biocompatibility All patient contacting materials used in the device are identical to those used in other FDA cleared devices, in formulation and processing, and no other chemicals have been added (e.g. plasticizers, fillers, cleaning agents, mold release agents, etc.). As usual for this type of device, the product has direct/indirect (salviamediated), permanent (> 30 days) contact with oral mucosa and hard tooth tissue (enamel, dentin). According to DIN EN ISO 10993-1 biological effects which have to be considered for this type of device to prove biological safety are cytotoxicity, tissue/ mucosa irritation, sensitization, systemic toxicity, genotoxicity/ carcinogenicity and chronic toxicity.

> DD Bio Z zirconia was tested by an accredited testing laboratory regarding cytotoxicity (according to DIN EN ISO 10993-5) and biological compatibility (according to DIN EN ISO 10993-1). To prove biocompatibility chemical analysis of organic and inorganic contaminants have been done. This highly sensitive chemical and biological test methods substantiated the known inert material properties and justifies the non-performance of additional toxicological tests. The material was classified as eminently suitable for use in the dental sector.

> Based on the established use of the identical material in cleared devices, and on testing of the materials to the biocompatibility requirements of design standard ISO 6872:2008, additional biocompatibility testing is not considered necessary.

- Dental Direkt of Amerika UG (haftungsbeschraenkt) did not Clinical and Non-Clinical Testing conduct nor rely upon clinical tests to determine substantial equivalence. Non-clinical testing was performed in order to validate the design against the company's specified design requirements, and to assure conformance with the following voluntary design standard: ISO 6872:2008
- Risk Management The device has been designed to either completely eliminate or mitigate known health hazards associated with the use of the device. Health hazard risk reduction has been accomplished by rigorous application of a risk management program according to ISO 14971 "Medical devices - Application of risk management to medical devices".
- Technological The difference between the products of the predicate device

{6}------------------------------------------------

characteristics K093748 and the products in the current 510(k) submission is a modification of raw materials used in the manufacture of milling blanks. Even if the material group 3Y-TZP staved the same, the properties differ significantly and are improved. The indication of use for the predicate K093748 "Dental Blanks made from DD Bio Z or DD Bio Z transpa are indicated for crowns, multi-unit bridges and inlay bridges. Applications include both anterior and posterior bridges" is the same as for the new product, only the product names were summarized as "DD Bio Z-dental blanks" in the new indication for use.

> The modification is mainly a slightly change in the chemical composition by increasing the alumina content for the translucent variant DD Bio ZX2. The raw material as used for the predicate device DD Bio Z transpa had nearly no alumina contained. The missing alumina in the zirconia structure and the recommendation of a higher final sintering temperature lead to an increased grain growth and more translucency but a lowered flexural strength in comparison to DD Bio Z. Compared to DD Bio Z transpa the new DD Bio ZX2 material with an increased alumina content is an improvement. DD Bio ZX2 is still more translucent than the DD Bio Z material even if the sintering temperature recommendation is now the same as for DD Bio Z and the flexural strength was enhanced in comparison to the DD Bio Z transpa material. Furthermore, the utilization of colouring oxides was excluded in the first submission.

Brief summary:

Substantial Equivalence Conclusion

The material group 3Y-TZP for the products in this submission and the predicate submission stayed the same. All ceramic zirconia products incorporates the same intended use with the predicate device. The increase of Alumina content in the raw material as used for DD Bio ZX2 compared to the predicate DD Bio Z transpa leads to an increase in flexural strength.

Beside this improvement the technological characteristics between the predicate and proposed devices are identical. There is no difference in fundamental scientific technology. The colouring dopants in pre coloured variants have no influence on material properties They have similar labels and instructions for use (see chapter 21 "Predicates").

Dental Direkt of Amerika UG (haftungsbeschraenkt) believes that DD Bio Z-dental blanks are as safe and effective as the predicate devices when used as instructed by knowledgeable and trained personnel, and are substantially equivalent to the legally marketed predicate devices.
