The system consists of porcelain blocks cemented to a milling machine-specific mandrel. Dental professionals use CAD/CAM milling machines (e.g., Aadva, CEREC, E4D) to mill the blocks into indirect restorations such as crowns, inlays, onlays, or veneers. Post-milling, restorations may be customized with porcelain stain. The material composition allows for milling without requiring firing in a porcelain furnace. The device is used in dental clinics or laboratories. The output is a custom-milled dental restoration that replaces missing or damaged tooth structure, potentially benefiting the patient by restoring dental function and aesthetics. ## Clinical Evidence Bench testing only. Performance evaluated against ISO 6872:2008 standards, including chemical solubility, flexural strength, linear thermal expansion, and radioactivity. Results showed MSCB-001 (HT and LT variants) met all requirements. Flexural strength (210-214 MPa) exceeded the predicate (145 MPa). Chemical solubility and thermal expansion were statistically equivalent or within acceptable limits compared to the predicate. ## Technological Characteristics Feldspathic (glass) porcelain block system derived from phyllosilicates (potash/soda feldspar), fluxes, and refractive oxides. Form factor: block on mandrel. Dimensions: 12, 14, 14L. Connectivity: compatible with CAD/CAM milling systems (Aadva, CEREC, E4D). Standards: ISO 6872:2008, ISO 10993-1:2009. Shelf life: 10 years. ## Regulatory Identification Porcelain powder for clinical use is a device consisting of a mixture of kaolin, felspar, quartz, or other substances intended for use in the production of artificial teeth in fixed or removable dentures, of jacket crowns, facings, and veneers. The device is used in prosthetic dentistry by heating the powder mixture to a high temperature in an oven to produce a hard prosthesis with a glass-like finish. ## Predicate Devices - VITABLOCS FOR CEREC MARK II ([K022408](/device/K022408.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

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. - 5.

Shelf Life: 10 years from date of manufacture ### 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). - 12. 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. 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. - 13. 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). {5}------------------------------------------------ # Table 5.1.1 Comparison Table | | Applicant device | Comparative device | Difference

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. --- **Source:** [https://fda.innolitics.com/submissions/DE/subpart-g%E2%80%94miscellaneous-devices/EIH/K152274](https://fda.innolitics.com/submissions/DE/subpart-g%E2%80%94miscellaneous-devices/EIH/K152274) **Published by [Innolitics](https://innolitics.com)** — a medical-device software consultancy.
