No
The description focuses on the material properties and the 3D printing process (stereolithography) based on scanned images, with no mention of AI or ML for image analysis, design, or process control.
No.
The device is a material (methacrylate-based resin) used to fabricate custom-made dental restorations, which are prosthetic devices used to replace or restore tooth structure, rather than directly treating a disease or condition. While the restorations themselves serve a therapeutic purpose by restoring function and form, the material used to create them is not considered a therapeutic device in itself.
No
The device description clearly states its purpose is to fabricate dental restorations (e.g., inlays, crowns) based on scanned images, which is a manufacturing function, not a diagnostic one. It takes input from existing diagnostic data (scanned images) but does not provide diagnostic information itself.
No
The device description clearly states that Temporis and Irix Plus are methacrylate-based resins, which are physical materials used to manufacture dental restorations. The process involves solidification by laser-induced polymerization using 3D printing equipment. This indicates a physical device, not a software-only one.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Definition of IVD: An In Vitro Diagnostic device is a medical device that is intended for use in the examination of specimens derived from the human body in order to provide information for diagnostic, monitoring, or compatibility purposes. This includes tests performed on blood, urine, tissue, etc.
- Function of this device: Temporis and Irix Plus are materials used to fabricate dental restorations. They are used in a 3D printing process to create physical objects (crowns, bridges, etc.) based on scanned images of the patient's mouth.
- Lack of diagnostic function: The device itself does not perform any diagnostic test on a biological specimen. It is a manufacturing material used to create a physical prosthesis.
While the process involves scanned images of the patient's mouth, which are derived from the human body, the device's function is not to analyze these images for diagnostic information. The images are used as a template for the physical creation of the restoration.
Therefore, based on the provided information, Temporis and Irix Plus are considered dental restorative materials and not In Vitro Diagnostic devices.

Device Description
Temporis and Irix Plus are methacrylate-based resins used to manufacture high-precision threedimensional custom-made dental restorations based on scanned images of the mouth of the patient. They are liquid resins that are subjected to solidification by laser induced polymerization - that is the process where monomers in liquid phase combine together to convert into polymers in solid phase - using dedicated 3D printing equipment working on the principle of stereolithography. The shape of the dental restoration is determined by a 3D stereolithographic drawing.
Temporis is used for manufacturing temporary dental restorations - such as inlays, onlays, veneers, anterior or posterior crowns and bridges (up to one pontic) - prior to the application of a permanent restoration. Irix Plus is used for manufacturing permanent dental restorations used to replace a decayed portion of tooth structure, like inlays, onlays, veneers, anterior or posterior crowns and bridges (up to one pontic).

Dear Anna Maria:
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 (the 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 available 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.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.

The subject and predicate device share the same indications for use, they are both light-curing 3Dprinting materials indicated as indirect restorative for anterior and posterior restorations.
The predicate device can be used for both temporary and permanent restorations just as the proposed resins Temporis and Irix Plus.
The materials used for the subject device are the same or similar to those used for the predicate device. Both the devices are methacrylate-based resins for 3D printing to be used to create a customized dental restoration. Methacrylate based resins are well known materials, commonly used in the dental industry for temporary and permanent dental restorations. The biocompatibility and performance testing show that slight differences in material composition do not raise any questions of safety or effectiveness; the subject device has demonstrated suitability for intended use through material non-clinical performance testing.
The proposed and predicate device are liguid photopolymers that are subjected to solidification by laser induced polymerization. Fabrication of the dental restorations requires for both the subject and the predicate device a computer-aided and manufacturing (CAD/CAM) system that includes the following: scanner, design software, additive printer, and post-cure unit.
The subject device has similar physical properties as the predicate device. The difference in the proposed shelf life will not raise new question on the new safety and effectiveness of the subject device as shown by the results of the stability testing performed.
