The summary describes a physical dental restoration block and its material properties, with no mention of software, algorithms, or data processing that would indicate AI/ML.
No.
The device is a material (porcelain block) used to fabricate indirect dental restorations, which are used to restore the form and function of teeth. It does not directly treat or diagnose a disease or condition in a therapeutic manner.
No
The device is a block system for fabricating indirect dental restorations (crowns, inlays, onlays, veneers) using CAD/CAM milling, which is a manufacturing process, not a diagnostic one.
No
The device description clearly describes a physical block system made of porcelain, designed to be milled by a CAD/CAM machine. This is a hardware component, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for creating dental restorations (crowns, inlays, onlays, veneers). This is a therapeutic and restorative purpose, not a diagnostic one.
- Device Description: The device is a material (porcelain block) used in a manufacturing process (CAD/CAM milling) to create a physical dental restoration. It does not interact with biological samples (blood, urine, tissue, etc.) to provide diagnostic information.
- Performance Studies: The performance studies focus on material properties relevant to dental restorations (chemical solubility, flexural strength, thermal expansion), not on diagnostic accuracy or performance related to analyzing biological samples.
IVD devices are used to examine specimens derived from the human body to provide information for the diagnosis, prevention, monitoring, treatment, or alleviation of disease. This device does not fit that description.

Device Description
MSCB is a block system consisting of a porcelain block cemented to a milling machine specific mandrel. This block/mandrel is designed to be milled in a CAD/CAM milling machine that is programmed to fabricate an indirect restoration. After milling, the restoration can be customized by use of porcelain stain. The composition of this product allows for milling without need to fire in a porcelain furnace.
MSCB-001 system is a feldspathic (glass) porcelain system based on partially crystalline but mostly vitreous materials derived from phyllosilicates such as potash or sodafeldspar, several commercially available fluxes, and various refractive oxides for mechanical enhancement.

9. Biocompatibility
According to ISO 10993-1: 2009, the following is stated:
*Sec 4.1 "Evaluation may include both a study of relevant preclinical experience and actual testing. Such an evaluation might result in the conclusion that no testing is needed if the material has a demonstrable safe history of use in a specified role and physical form that is equivalent to that of the device under design."
*Sec 6.1 "Material characterization: "If the combination of all materials, chemicals and processes has an established history of safe use in the intended application, then further characterization and biological evaluation might not be necessary."
All components in MSCB-001 have been used in predicate product, such as VITABLOCS FOR CEREC. Based on above, MSCB was considered to have an acceptable level of biocompatibility
All devices come in contact with the same body tissues (tooth - enamel, dentin) for more than 24 hours.
10. Performance Testing - Bench:
It is confirmed that the device conforms to the required specifications of ISO 6872:2008 and is suitable for its intended use.
Performance testing includes:
- . Chemical solubility
- . Flexural strength
- Linear thermal expansion .
- o Radioactivity
Technological characteristics: 11.
All the components of the applicant device, MSCB-001, have already been used in the predicate device (VITABLOCS FOR CEREC MARK II).
-
- Substantial equivalence:
The new and predicate device (VITABLOCS FOR CEREC MARK II) are the same in function, and similar in composition and intended use. This supports that the compatibility of the applicant device is substantially equivalent to the predicate devices.
- Substantial equivalence:
The substantial equivalence was viewed looking at comparison to standards as well as the predicate device.
Differences:
Compared to VITABLOCS FOR CEREC MARK II, MSCB-001 has a higher flexural strength using ISO 6872.
-
- Conclusion
Based on a comparison of intended use, indication for use, composition, and shelf life, GC concludes that MSCB-001 is substantially equivalent to the predicate device (VITABLOCS FOR CEREC MARK II: K022408).
- Conclusion

Table 5.2.1 Summary of Performance Specifications
Comparing test results between applicant and predicate device for the properties of chemical solubility they were statistically equivalent and met or exceeded requirements of ISO 6872:2008.
Comparing test results between application and predicate device for the properties of flexural strength, they were statistically different with MSCB-001 having higher values. Both devices exceeded performance specification minimum.
Comparing test results between predicate and applicant device for linear thermal expansion with a TG of +/-10℃, the standard deviation of products tested were within the SD limitations requirement.
The properties listed, tested and results indicate that the application and predicate device are within the standard ISO 6872:2008. When compared to the predicate device already in the market, the performances of MSCB-001 are at least statistically equivalent and, therefore, can be considered clinically acceptable.
