No
The device description and performance studies focus on the material properties and chemical effects of a coloring liquid for dental restorations, with no mention of AI or ML algorithms for analysis, diagnosis, or treatment.
No.
The device, BruxZir Steel™, is described as a coloring liquid used as an accessory to dental restorative material to provide shading and improve strength, not to treat or prevent a disease or condition.
No
BruxZir Steel™ is described as a coloring liquid used to enhance the aesthetic and mechanical properties of zirconium dioxide dental restorative materials, not to diagnose a medical condition.
No
The device description clearly states that BruxZir Steel™ is a "Coloring Liquid" and describes its physical properties and application to a physical material (zirconia). The performance studies also focus on material properties like biocompatibility, mechanical strength, and color, which are characteristic of a physical substance, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In vitro diagnostic devices are used to examine specimens taken from the human body (like blood, urine, or tissue) to provide information about a person's health.
- BruxZir Steel™'s Intended Use: The intended use of BruxZir Steel™ is to be used as an accessory to dental restorative material for shading and producing dental prostheses. It is applied to a material (zirconium dioxide) outside the human body during the fabrication process.
- No Specimen Analysis: The description does not mention any analysis of human specimens. The performance studies focus on the material properties of the treated zirconia (biocompatibility, mechanical strength, color).
Therefore, BruxZir Steel™ is a dental material accessory used in the fabrication of dental restorations, not a device used for in vitro diagnostic testing.
N/A
Intended Use / Indications for Use
BruxZir Steel™ can be used as an accessory to zirconium dioxide dental restorative material to provide individual tooth (or teeth) shading and to produce a strong prosthesis with a porcelain-like finish. It is intended to be used solely by certified dental technicians for fabrication of zirconium dioxide restorations for individual dental patients.

C. IDENTIFICATION OF PREDICATE DEVICE
Primary Predicate: DMAX Coloring Liquid (K173769)
Reference Device: ZirBlank®-FS (K070045)
D. DEVICE DESCRIPTION
BruxZir Steel™ is a Coloring Liquid used to produce a natural whitening effect while increasing the flexural strength and fracture toughness of 4.6 - 4.9 mol% yttriastabilized zirconia (YSZ). The product increases the shade esthetics of the restoration while maintaining the translucency. Application of the zirconia substrate prior to sintering provides enhanced shade characteristics and improved flexural strength and fracture toughness.
E. INDICATIONS FOR USE
BruxZir Steel™ can be used as an accessory to zirconium dioxide dental restorative material to provide individual tooth (or teeth) shading and to produce a strong prosthesis with a porcelain-like finish. It is intended to be used solely by certified dental technicians for fabrication of zirconium dioxide restorations for individual dental patients.
F. DETERMINATION OF SUBSTANTIAL EQUIVALENCE
The subject device, BruxZir Steel™, is substantially equivalent to the primary predicate device, DMAX Coloring Liquid, (K173769) in intended use, material, design and performance.
The Indications for Use Statement (IFUS) for the subject device is substantially equivalent to that of the primary predicate. Both the subject device and the primary predicate device can be used as an accessory to zirconium dioxide dental restorative material to provide individual tooth (or teeth) shading and intended to be used solely by certified dental technicians for fabrication of zirconium dioxide restorations for individual dental patients. Slight difference in the subject device and primary predicate device Indications for Use does not affect the intended use and is supported by the reference device, ZirBlank®-FS (K070045). The subject device and the reference device include tantalum. The performance testing data also supports a new indication for use by showing that the subject device increases the flexural strength and fracture toughness of zirconia. Both IFUS express equivalent intended use to facilitate fabrication of zirconium dioxide restorations for individual dental patients, and indication for a strong prosthesis with a porcelain-like finish is expressed equivalently using different specific wording.

K200131
The differences between the predicate device and the subject device in terms of chemical composition are the presence of tantalum(V) oxide, less amount of silicon dioxide, and absence of sodium in the subject device. After sintering, the remaining tantalum pentoxide, which is incorporated into the zirconia substrate, is proven biocompatible. Silicon dioxide in the predicate device is a whitening agent, which makes the zirconia restoration whiter. The absence of sodium in the subject device does not affect the intended use.
Although the base solutions for BruxZir Steel™ and DMAX Coloring Liquid are not identical (i.e. alcohol-based solution and water-based solution respectively), the difference does not affect the intended use, performance characteristics, or principle of operation.
The subject device and the reference device employ tantalum prior to sintering the zirconia substrate. Substantial equivalence of the subject device components to the reference device in terms of biocompatibility is supported by the fact that tantalum has been acknowledged as being biocompatible for use in dental applications. Nonetheless, biocompatibility testing was performed on the subject device and the device was proven biocompatible.
The comparison table below (Table 7-1) outlines and provides the similarities and differences among the subject device, primary predicate device and reference device.
In summary, the subject device is substantially equivalent to the predicate device.
PERFORMANCE DATA G.
Non-clinical data submitted to demonstrate substantial equivalence included:
- Biocompatibility according to ISO 10993-5:2009 and ISO 10993-10:2010 ●
- The Cytotoxicity Report shows that there was no evidence of causing cell । lysis or toxicity.
- The Sensitization Report shows that there was no reaction on the tested subject.
- The Irritation Report shows that the test article was considered a nonirritant. -
- Mechanical testing for flexural strength, fracture toughness, solubility . according to ISO 6872:2015
- . L* value obtained from Lab* color space testing after applying BruxZir Steel™ onto zirconia for dental restoration according to ISO 11664-4:2019.
Biological evaluation within a risk management process was performed in accordance with ISO 10993-1:2018 and EN ISO 14971:2012. No clinical data were included in this submission.
