Device Story

BruxZir Esthetic is a zirconia milling blank used by dental technicians in laboratories to produce custom all-ceramic dental restorations. The device is processed via CAD/CAM systems for design and milling, followed by high-temperature sintering. Unlike the predicate, which requires post-sintering staining and glazing to achieve target shades, BruxZir Esthetic is pre-shaded, allowing final target shades to be achieved without additional coloring steps. The device is intended for use in all regions of the mouth. The output is a finished dental restoration that restores patient dentition, providing high strength and esthetics.

The main components of the subject device, BruxZir® Esthetic, and the predicate device, BruxZir® Shaded (K130924), are substantially equivalent as generic type of material has not been changed and it does not alter the performance specifications of the subject device. The slight differences in overall chemical composition do not affect biocompatibility and performance characteristics. The fundamental principle of operation of the subject device, BruxZir® Esthetic, and the predicate device, BruxZir® Shaded (K130924), is similar. The difference between the subject device and the predicate device is that the final target shades are achievable without additional coloring steps for the subject device whereas basic staining and glazing techniques are required after sintering in order to achieve the final target shades for the predicate device. Also, the change in the manufacturing process from colloidal process (slip casting) to press process does not affect the mechanical properties of the final finished device. The substantial equivalence comparison table above outlines and provides the similarities between the subject device, BruxZir® Esthetic, and the predicate device, BruxZir® Shaded (K130924). Both the subject device and the predicate device have similar physical/mechanical and biocompatibility properties that met the requirements of ISO 6872:2015/Amd 1:2018 (Type II, Class 5) and ISO 10993. Any differences between the subject device and the predicate device do not raise any new concerns of safety and effectiveness. {7}------------------------------------------------ Image /page/7/Picture/0 description: The image contains the logo for Prismatik Dentalcraft, Inc. On the left is a triangle with a gradient of colors from blue to pink. To the right of the triangle is the company name, "PRISMATIK DENTALCRAFT, INC." in blue font. #### VII. PERFORMANCE DATA Non-clinical data submitted to demonstrate substantial equivalence included: - Mechanical testing for flexural strength, Coefficient of Thermal Expansion 0 (CTE), solubility, radioactivity according to ISO 6872:2015/Amd 1:2018 - Color consistency, translucency, shade match ● - Packaging validation ● - Biocompatibility o ### Flexural Strength The flexural strength was tested on the worst-case group. The average flexural strength of each worst-case block batch tested yielded results above the 800 MPa minimum. The results demonstrate that the product's flexural strength meets the ISO 6872: 2015/Amd 1:2018 requirement to be classified as a Type II, Class 5 ceramic product. ### Coefficient of Thermal Expansion (CTE) Coefficient of Thermal Expansion (CTE) was tested in order to demonstrate compliance with the ISO 6872:2015/Amd 1:2018 requirement. Tests performed on the high and low colorant extreme shades vielded CTE results within the specification range of 10-11 x 10-6/ºC and a standard deviation of less than 0.5 x 10-6/ºC. The results met the ISO 6872:2015/Amd 1:2018 CTE requirement. ## Solubility Based on the solubility results from similar products that share the same base powder, approximate yttria content, same series of colorants and method of introduction, it was concluded the solubility is below 100 µg/cm2 limit, meeting the ISO 6872:2015/Amd 1:2018 requirement. ### Radioactivity Since BruxZir® Esthetic is produced entirely from the raw materials, which have been certified to meet the radioactivity requirement of ISO 6872:2015/Amd 1:2018, and the processes through which those powders are transformed into a finished product inherently do not induce radioactivity, BruxZir® Esthetic meets the radioactivity requirement of ISO 6872:2015/Amd 1:2018 without the need for further testing of the finished product. ### Color Consistency Color consistency within a block, within a batch and between batches was tested. A ΔE of less than 2.0 between two coordinates in the CEILAB color space is considered indicative that two shades being perceptibly identical to one another. With the maximum ΔE calculations being made between the minimum and maximum L *, a*, and b* coordinate constituents within each dataset falling below 2.0, it was concluded that BruxZir® Esthetic conforms to color consistency requirements for and between the batch sizes, block types, and press densities tested. The results of the testing were used to address questions related to substantial equivalence based on differences in {8}------------------------------------------------ Image /page/8/Picture/0 description: The image shows the logo for Prismatik Dentalcraft, Inc. On the left is a triangular prism with a color gradient. The text "PRISMATIK DENTALCRAFT, INC." is on the right in blue. device design between the subject device, BruxZir® Esthetic, and the predicate device, BruxZir® Shaded (K130924). ### Translucency Translucency was tested for every batch as well as each thickness of Zeno block pressed. The results show that BruxZir® Esthetic to be more translucent than the reference product; therefore, demonstrating conformance with acceptance criteria for translucency. The results of the testing were used to address questions related to substantial equivalence based on differences in device design between the subject device, BruxZir® Esthetic, and the predicate device, BruxZir® Shaded (K130924). ## Shade Match Shade match validation was performed on restorations milled and sintered from each block type pressed from each batch. Evaluations of sintered and glazed restorations by qualified reviewers against the VITA Classical and Bleach shade guides concluded that BruxZir Esthetic meets shade match requirements for all batch sizes, restoration types, and press densities tested. The results of the testing were used to address questions related to substantial equivalence based on differences in device design between the subject device, BruxZir® Esthetic, and the predicate device, BruxZir® Shaded (K130924). ## Packaging Validation Packaging validation was also performed for different styles, GL Single Unit and GL Bridge Block, offered for BruxZir® Esthetic. Per ASTM D4169-14, the shipping unit was tested for manual handling, compressive loads, repetitive shocks from vibration, vertical vibration environments, concentrated impacts and secondary manual handling drops. After the tests, the shipping containers were visually inspected for any damages. It was determined that the GL Singe Unit and GL Bridge Block with their respective packaging, is suitable for use. The results of the testing were used to address questions related to substantial equivalence based on differences in product packaging between the subject device, BruxZir® Esthetic, and the predicate device, BruxZir® Shaded (K130924). ### Biocompatibilitv Biological evaluation within a risk management process was performed in accordance with ISO 10993-1:2018 and ISO 14971:2019. Based on the biocompatibility testing results from similar products, it was determined that there is no biocompatibility concern in regards to yttria concentration, colorants, or organic binders. The results of the testing were used to address questions related to substantial equivalence based on differences in chemical composition between the subject device, BruxZir® Esthetic, and the predicate device, BruxZir® Shaded (K130924). #### VIII. CONCLUSION BruxZir® Esthetic was evaluated for substantial equivalence using standard and/or comparative testing. Based on technological characteristics and non-clinical test data {9}------------------------------------------------ Image /page/9/Picture/0 description: The image contains the logo for Prismatik Dentalcraft, Inc.
