The device description and performance studies focus on the material properties and mechanical performance of a dental cement and core build-up composite, with no mention of AI or ML technology.
No.
The device is described as an adhesive cementation and core build-up composite used for permanent cementation of dental restorations and core build-ups. It helps in the mechanical attachment and support of dental structures rather than treating or preventing a disease or condition directly.
No
Visalys® CemCore is a dual-curing, adhesive cement and core build-up composite used for permanent cementation and core build-ups. While it includes a "Try In Paste" for shade matching, this is for aesthetic selection and not for diagnosing a medical condition.
No
The device description clearly describes a physical composite material (paste) used for dental procedures, not a software application.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly describes the device as a dental material for permanent cementation of restorations and core build-ups. This is a therapeutic and restorative application, not a diagnostic one.
- Device Description: The description details the composition and properties of a dental composite material. It does not mention any components or functions related to analyzing biological samples or providing diagnostic information.
- Lack of Diagnostic Elements: There is no mention of analyzing blood, urine, tissue, or any other biological sample. The device is applied directly to the tooth structure.
- Performance Studies: The performance studies focus on biocompatibility and mechanical properties relevant to a dental restorative material, not diagnostic accuracy metrics like sensitivity, specificity, etc.
In vitro diagnostics are devices used to examine specimens from the human body to provide information for diagnosis, monitoring, or screening. This device does not fit that definition.

Device Description
Visalys® CemCore is a dual-curing composite containing fluoride for adhesive cementation of indirect restorations and root posts and can be used to fabricate radiopaque core build-ups and abutment fillings. Due to the Active-Connect-Technology (ACT) Visalys® CemCore includes an additional initiator system for the optimization of the adhesive bond. BPA or BPA precursors are not used in the manufacturing process of this device. Visalys® CemCore shall only be used in combination with self-etching Visalys® Tooth Primer. Visalys® Restorative Primer is recommended as the primer for the restoration surfaces. Visalys® CemCore is easy to use and has high adhesive strength and good flowability with stable consistency. Visalys® CemCore is offered in the shades Universal (A2/A3), Dark (A4), Opaque, Bleach and Translucent. The paste should be mixed and dispensed directly from a double syringe with the corresponding mixing tips blue (MLø 3.2 mm). Visalys® CemCore Try in Paste serves to simulate the shade effect of the selected Visalys® CemCore shade on ceramic restorations and for covering the cement joint to reduce a layer of inhibition. The water-soluble paste corresponds in shade and translucence with the completely cured Visalys® CemCore. Visalys® CemCore Try In Paste is offered in the shades Universal (A2/A3), Dark (A4), Opaque, Bleach and Translucent. The paste is dispensed from a syringe and syringe tip.

Summary of Performance Studies
Biocompatibility tests have been performed to assure biological safety in accordance with the ISO 10993 family and ISO 7405. Tests in respect to cytotoxicity (ISO 10993-5), mutagenicity (OECD 487), sensitization (ISO 10993-10) and a chemical analysis (10993-18) showed, that the biocompatibility data of Visalys® CemCore is comparable to other materials on the market. Therefore no toxicological risks and resulting hazards for patients, users and third parties can be concluded. Additionally bench testing was performed to allow an evaluation of the mechanical properties of Visalys® CemCore in comparison to Visalys® Core (K143104/Secondary Predicate) and Multilink® Automix (K123397/Primary Predicate).

Dear Katja Simon:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products.
