BruxZir® Incisal Coloring Liquid is intended to be used by trained dental technicians as an accessory for shading BruxZir® Shaded 16 PLUS and BruxZir® Esthetic all zirconia, monolithic restorations for anterior and posterior dental prosthetics.

Device Description

BruxZir™ Incisal Coloring Liquid comprises a set of solutions that enhance the esthetic properties of zirconia restorations. The solution is applied to the zirconia restorations before sintering, by dipping the framework into the liquid or by using a metal-free brush. Afterwards, the structure is dried and subsequently sintered at temperatures above 1400°C. BruxZit™ Incisal Coloring Liquid is available in 3 different colors, Premium, Premium HT, and Pearl. The devices are used on incisal areas of dental restoration to mimic natural tooth color. The devices are intended to be used solely by dental technicians for fabrication of zirconia restorations for individual dental patients.

AI/ML Overview

The "BruxZir™ Incisal Coloring Liquid" is an accessory for shading zirconia dental restorations. The acceptance criteria and the study proving it meets these criteria are described below:

1. Table of Acceptance Criteria and Reported Device Performance:

Acceptance Criteria	Device Performance (BruxZir™ Incisal Coloring Liquid)	Standard/Requirement
Mechanical Properties	Meets minimum mechanical properties of zirconia for Type II, Class 5	ISO 6872:2015/Amd 1:2018
Flexural Strength	Satisfies requirements for Type II, Class 5 zirconia	ISO 6872:2015/Amd 1:2018
Chemical Solubility	Below 100 ug/cm² limit	ISO 6872:2015/Amd 1:2018
Material Properties
Biocompatibility	No biocompatibility concern	ISO 10993-1, ISO 10993-5:2009
Functional Properties
Visual Shade Match	Meets shade match requirements and works as intended	Based on qualified reviewer evaluation against reference shade guides
Shelf Life	0.5 years (accelerated aging)	ASTM F1980-21
Packaging Integrity	Suitable to withstand distribution environment	Similar to reference device (K220960) packaging validation

2. Sample Size Used for the Test Set and the Data Provenance:

The document doesn't explicitly state the sample sizes for each specific test (e.g., number of restorations tested for flexural strength, number of specimens for chemical solubility). It also doesn't specify the country of origin for the data or whether the studies were retrospective or prospective.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications:

For the "Visual Shade Evaluation," the document states "qualified reviewers" performed the evaluation. However, it does not specify the number of reviewers, their professional qualifications (e.g., dental technicians with X years of experience, ceramists), or how "qualified" is defined.

4. Adjudication Method for the Test Set:

For the "Visual Shade Evaluation," it simply states the evaluation was done "against the reference shade guides." No specific adjudication method (e.g., 2+1, 3+1) is described for resolving discrepancies, implying a single reviewer's assessment or a consensus without a formal adjudication process. For other tests, the outcomes are quantitative measurements against established standards, so an adjudication method is not applicable.

5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was Done:

No, an MRMC comparative effectiveness study was not done. The submission is focused on demonstrating substantial equivalence to a predicate device through non-clinical performance testing.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was Done:

This device is not an AI/algorithm-based device, so the concept of "standalone performance" in that context is not applicable. The device is a coloring liquid used in the fabrication process of dental prosthetics.

7. The Type of Ground Truth Used:

Mechanical Properties (Flexural Strength, Chemical Solubility): The ground truth is defined by established international standards (ISO 6872:2015/Amd 1:2018), which specify minimum acceptable performance values.
Biocompatibility: Ground truth is established by international standard (ISO 10993-1, ISO 10993-5:2009) requirements.
Visual Shade Evaluation: Ground truth is established by "reference shade guides" and evaluation by "qualified reviewers."
Shelf Life: Ground truth is based on the methodology outlined in ASTM F1980-21.
Packaging Validation: Ground truth is based on established testing protocols to ensure packaging integrity.

8. The Sample Size for the Training Set:

This device is not an AI/machine learning device, so there is no concept of a "training set" in the traditional sense.

9. How the Ground Truth for the Training Set Was Established:

As there is no training set, this question is not applicable.

The logo features a colorful triangular prism on the left, with the company name written in blue text to the right. The word "PRISMATIK" is on the top line, and "DENTALCRAFT, INC." is on the bottom line.

subject device and the primary predicate device are the same except for the device name and compatible products. Both devices are liquids used for coloring pre-sintered zirconia restorations. The fundamental principle of operation of the subject device and the primary predicate device is the same. The subject device and the primary predicate device are similar as aqueous solutions, but they are different in terms of chemical composition. However, the performance testing results of the subject device support that the subject device is substantially equivalent to the primary predicate device.

The substantial equivalence comparison table above outlines and provides the similarities between the subject device, BruxZir™ Incisal Coloring Liquid, and the primary predicate device, ArgenZ Liquids (K182833). Both the subject device and the primary predicate device have similar physical/mechanical and biocompatibility properties that met the requirements of ISO 6872:2015/Amd 1:2018 and ISO 10993. Any differences between the subject device and the primary predicate device do not raise any new concerns of safety and effectiveness.

VII. PERFORMANCE DATA

The subject device, BruxZir™ Incisal Coloring Liquid, uses the same packaging materials and packaging configurations as the reference device, BruxZir"M Opaque Coloring Liquid (K220960). The results of the previous packaging validation were used to address questions related to substantial equivalence based on differences in packaging configuration between the subject device, BruxZir™ Incisal Coloring Liquid, and the primary predicate device, ArgenZ Liquids (K182833).

Biocompatibilitv

The subject device, BruxZir™ Incisal Coloring Liquid, was tested in accordance with ISO 10993-1. Per the biological evaluation. BruxZir™ Incisal Coloring Liquid was tested for Cytotoxicity (ISO 10993-5:2009) to meet the biocompatibility requirements. Based on the biocompatibility testing results, it was determined that there is no biocompatibility concern for the subject device. 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™ Incisal Coloring Liquid, and the primary predicate device, ArgenZ Liquids (K182833).

VIII. CONCLUSION

Based on the technological characteristics and non-clinical test data included in this submission, the subject device, BruxZir'™ Incisal Coloring Liquid, has been shown to be substantially equivalent to the primary predicate device ArgenZ Liquids (K182833).
