The summary describes a dental resin and its use in a CAD/CAM system for fabricating dental prosthetics. While it involves digital imaging and design, there is no mention or indication of AI or ML being used in the process of designing, fabricating, or evaluating the prosthetics. The process relies on clinician judgment and standard CAD/CAM workflows.
No.
The device, SprintRay Digital Crown, is a light-curable resin used for fabricating dental crowns, veneers, and dentures. It is a material used to replace missing or damaged dental structures, which falls under restorative devices rather than therapeutic devices that treat a disease or condition.
No
This device is a material (light-curable polymerizable resin) used for the fabrication of dental prosthetics. Its intended use is to create physical crowns, veneers, and dentures, not to diagnose medical conditions or diseases.
No
The device description clearly states that the device is a "light-curable polymerizable resin" and a "curable dental acrylate resin." It is a physical material used in the fabrication of dental prosthetics, not a software program.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for the fabrication of dental prosthetics (crowns, veneers, dentures, etc.). This is a restorative and manufacturing process, not a diagnostic one.
- Device Description: The device is a light-curable polymerizable resin used in a 3D printing process to create physical dental appliances. It's a material used in manufacturing, not a test or assay performed on a biological sample to provide diagnostic information.
- Input: The input is a 3D scan or digital file of the patient's teeth or manufacturer's data, not a biological sample like blood, urine, or tissue.
- Performance Studies: The performance studies focus on the physical properties of the material and the fabricated device (biocompatibility, strength, accuracy, etc.), not on the ability to diagnose a condition or provide diagnostic information.
IVD devices are used to examine specimens derived from the human body to provide information for diagnostic, monitoring, or compatibility purposes. This device does not fit that description.
N/A

Device Description
SprintRay Digital Crown resin consists of a curable dental acrylate resin that is manufactured in a dental office based on a 3D scanned image of a patient's teeth. The acrylate resin material is designed to be used in conjunction with a scanned 3D image, and 3D printer assembly, to locally manufacture out a dental appliance based on the clinician's judgment of patient need.
Fabrication of dental prosthetics with SprintRay Digital Crown resin requires computer-aided design and CAD/CAM manufacturing system that includes the following components not part of the device: oral casting impression, digital crown file created in an optical impression system, 3D printer, and curing light equipment. SprintRay Digital Crown Resin is intended exclusively for professional dental work. Digital Crown Resin is offered in following shades/colors: Bleach, A1, B1.
The device is manufactured via additive manufacturing process using a 3D printer with 405 nm wavelength, 50 m print layer thickness, and light energy of 28.8 mW/cm².
Digital Crown resin is designed to meet appropriate ISO standards for flexibility and sorption, to withstand prolonged use in the oral cavity. It is delivered nonsterile, and instructions are provided on cleaning the material prior to providing it to a patient. Curing is performed with a UV lamp. The appliance is then cleaned, trimmed, and verified to fit in the dental office before the patient leaves.

Conclusions
Digital Crown resin is as safe and effective as its predicate device. Digital Crown resin has the same intended use and indication, and similar technological characteristics, and principles of operation as its predicate device. The minor technological differences between Digital Crown resin and its predicate devices raise no new issues of safety or effectiveness. Performance data demonstrate that Digital Crown resin is as safe and effective as the predicate device. Thus, Digital Crown resin is substantially equivalent.
