VITA LUMEX AC
VITA Lumex® AC is used to veneer the following:
- Full and partial veneering of zirconia
- Full and partial veneering of lithium disilicate
- Partial veneering of feldspar ceramic
- Reconstruction without a substructure
Materials: - Zirconia substructures (CTE approx. 10.0 to 10.5 x 10-6 K-1)
- Glass-ceramic substructures (CTE approx. 9.0 to 10.5 x 10-6 K-1)
VITA Lumex® AC is a natural low-fusing veneering ceramic system that is suitable for veneering all ceramic substructures. VITA LUMEX AC standard layering consists of the two Materials DENTINE and ENAMEL. The color-bearing DENTINE materials, which provide good coverage, offer the perfect precondition for the preparation of veneers with intensive shades. With this two-layer alternative, VITA offers an ideal solution for the reproduction of optimal shade results in case of thin walls. Additionally, the intensive shade effect of the DENTINE permits a more generous use of the ENAMEL materials, which create the desired translucency. The user is able to prepare a natural restoration with a lifelike appearance with only two layers. This product is provided non-sterile in glass jars in a powder form to be used in conjunction with the Vita low fusing liquid.
This document is a 510(k) Premarket Notification for the VITA Lumex® AC, a porcelain powder for clinical use, and not a study describing the acceptance criteria and performance of a device that meets those criteria.
Therefore, I cannot provide the requested information, which includes:
- A table of acceptance criteria and reported device performance.
- Sample size used for the test set and data provenance.
- Number of experts and their qualifications for establishing ground truth.
- Adjudication method for the test set.
- MRMC comparative effectiveness study results.
- Standalone (algorithm-only) performance.
- Type of ground truth used.
- Sample size for the training set.
- How ground truth for the training set was established.
The document states: "Non-Clinical Performance Testing" on page 5, indicating that "Bench test results allowed us to conclude that VITA Lumex® AC is substantially equivalent to the predicate device for its intended use." It also explicitly states "Clinical Performance Data: Not applicable. No human clinical testing was performed to support the substantial equivalence of VITA Lumex® AC."
This filing relies on bench testing and comparison to predicates, not specific clinical performance studies with acceptance criteria as requested in your prompt.
