No
The device description and performance studies focus on the physical and chemical properties of a dental luting cement and base/liner. There is no mention of AI, ML, or any computational analysis of data for diagnosis, treatment planning, or other clinical decision-making.
No
The device is a luting cement and base/liner used for dental restorations and appliances; it does not directly treat a disease or condition, but rather aids in the mechanical attachment and support of dental prosthetics.
No
Explanation: This device is a resin luting cement and base/liner used for bonding dental restorations. It does not identify, diagnose, or monitor diseases or health conditions.
No
The device description clearly indicates it is a physical material (resin luting cement and base/liner) used for dental restorations, not a software program.
Based on the provided information, this device is not an In Vitro Diagnostic (IVD).
Here's why:
- Intended Use: The intended use clearly describes the device as a dental luting cement and base/liner for bonding various dental restorations and appliances within the mouth. This is a direct application within the human body for structural and restorative purposes.
- Device Description: The description reinforces its function as a material used to bond dental components.
- No mention of testing samples from the human body: IVDs are designed to examine specimens derived from the human body (like blood, urine, tissue) to provide information about a physiological state, disease, or condition. This device does not perform such testing.
- Performance Studies: The performance studies focus on the physical, mechanical, and biocompatibility properties of the material itself, not on its ability to diagnose or provide information about a patient's health status based on a sample.
In summary, this device is a dental material used for bonding and lining within the oral cavity, which falls under the category of a medical device, but not an In Vitro Diagnostic device.

Device Description
TheraBase and TheraBase Ca are a self-etching, self-adhesive, dual-cured resin luting cement and base/liner that is exclusively formulated for luting crowns, bridges, inlays, onlays and posts (prefabricated metal and non-metal/fiber posts, as well as cast posts) and basing/lining under restorations. TheraBase is a paste/paste, fluoride- and calcium-releasing, luting cement and base/liner which requires no etching, no priming or bonding of the prepared surfaces. TheraBase Ca is a paste/paste, calcium-releasing, luting cement and base/liner which requires no etching, no priming or bonding of the prepared surfaces. They are easy-to use, require only a short chair time, and produce a good bond to most dental materials. The cements are available in a Natural shade. They are radiopaque, allowing for easy identification on radiographs.

Dear Diana Vu:
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. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.

The only change in the indication for use from TheraCem to TheraBase and TheraBase Ca is the addition of "Lining and basing applications under restorations." NuSmile BioCem is added as a reference predicate to demonstrate that it does not raise new questions of safety and effectiveness as it contains the same indication listed as "liner, base."

Description of Applicant Device:
TheraBase and TheraBase Ca are a self-etching, self-adhesive, dual-cured resin luting cement and base/liner that is exclusively formulated for luting crowns, bridges, inlays, onlays and posts (prefabricated metal and non-metal/fiber posts, as well as cast posts) and basing/lining under restorations. TheraBase is a paste/paste, fluoride- and calcium-releasing, luting cement and base/liner which requires no etching, no priming or bonding of the prepared surfaces. TheraBase Ca is a paste/paste, calcium-releasing, luting cement and base/liner which requires no etching, no priming or bonding of the prepared surfaces. They are easy-to use, require only a short chair time, and produce a good bond to most dental materials. The cements are available in a Natural shade. They are radiopaque, allowing for easy identification on radiographs.
Technological Characteristics:
All components of TheraBase and TheraBase Ca are based upon industry standard chemistry. The chemical composition of TheraBase is the same as TheraCem. The chemical composition of TheraBase Ca is similar to TheraCem. The chemical composition of TheraBase and TheraBase Ca is similar to NuSmile BioCem. The chemical compositon of each product is summarized in the table below:
| Chemical
Composition | TheraCem

The difference in filler is TheraCem's, TheraBase's, and TheraBase Ca's additional use of Portland cement, an industry standard chemical, to facilitate calcium release and is substantially equivalent in performance to amorphous silica.
