Intended Use

BruxZir® NOW is intended to be used in fabrication of dental restorations such as crowns and bridges for the purpose of restoring chewing function.

Device Story

BruxZir® NOW is a pre-shaded, fully sintered Yttria-stabilized zirconia (YSZ) CAD/CAM block. It is used by dental laboratories or professionals to fabricate single-unit or multiple-unit dental restorations (crowns and bridges) via CAD/CAM or manual milling systems. The device serves as the raw material for the restoration, which is milled based on the patient's anatomical tooth rendering. The final restoration restores chewing function. The device is provided in various shades and sizes.

Clinical Evidence

No clinical data included. Substantial equivalence supported by bench testing: flexural strength, solubility, shade evaluation, biocompatibility (cytotoxicity), radioactivity, and packaging validation (ASTM D4169-16). All tests met ISO 6872:2015/Amd 1:2018 and ISO 10993-1:2018 requirements.

Technological Characteristics

Material: Yttria-stabilized zirconia (YSZ) with pigments. Form: Fully sintered blocks in various sizes/shades. Mechanical: Flexural strength >800 MPa (Type II Class 5 per ISO 6872:2015/Amd 1:2018). Solubility: <100 µg/cm². Radioactivity: <1.0 Bq/g U-238. Biocompatibility: ISO 10993-1 compliant. Packaging: ASTM D4169-16 validated.

Indications for Use

Indicated for dental restorations using CAD/CAM or manual milling machines. Processed through dental laboratories or by dental professionals.

Regulatory Classification

## DETERMINATION OF SUBSTANTIAL EQUIVALENCE

The subject device, BruxZir® NOW, is substantially equivalent to the predicate device, Perfit FS Dental Zirconia Fully Sintered Block (K203590) in intended use, indications for use, material, design principles and technological characteristics.

The subject device, BruxZir® NOW, has the same intended use as the predicate device, Perfit FS Dental Zirconia Fully Sintered Block (K203590), as the material used in fabrication of dental restorations such as crowns and bridges for the purpose of restoring chewing function. The subject device, BruxZir® NOW, has the same indications for use statement (IFUS) as the predicate device, Perfit FS Dental Zirconia Fully Sintered Block (K203590), except for the device trade name. Both the subject device and the predicate device are dental restorative materials indicated for fabrication of dental restorations using CAD/CAM or manual milling machines. All blocks are processed through dental laboratories or by dental professionals.

The subject device, BruxZir® NOW, is substantially equivalent to the predicate device, Perfit FS Dental Zirconia Fully Sintered Block (K203590), in technological characteristics. The same mechanical property testing in terms of flexural strength that was conducted on the predicate device, Perfit FS Dental Zirconia Fully Sintered Block (K203590), was also conducted on the subject device, BruxZir® NOW, according to ISO 6872:2015/Amd 1:2018. The flexural strength of the subject device, BruxZir® NOW, passed the threshold of performance criteria in ISO 6872 for Type II Class 5. The flexural strength of the subject device, BruxZir® NOW, is higher than that of the predicate device, Perfit FS Dental Zirconia Fully Sintered Block (K203590), which passed the threshold of performance criteria in ISO 6872 for Type II, Class 4.

The subject device, BruxZir® NOW, and the predicate device, Perfit FS Dental Zirconia Fully Sintered Block (K203590), are similar in material composition. Both devices utilize Yttria-stabilized zirconia as the base material and pigments. Despite the differences in the pigments used to achieve the desired shades, the slight differences in chemical formulation do not affect the safety and effectiveness of the device as verified by the biocompatibility and performance testing.

The subject device, BruxZir® NOW, and the predicate device, Perfit FS Dental Zirconia Fully Sintered Block (K203590), are substantially equivalent in terms of design. Both are offered in a fully sintered block form in different shapes and shades and are used to make
