The summary describes a 3D printable resin for dentures and focuses on material properties and printing accuracy, with no mention of AI or ML.
No.
This device is a resin used for the fabrication and repair of dentures and baseplates, which are prosthetic devices, not therapeutic devices.
No
Explanation: The device is a light-curable resin used for the fabrication and repair of dentures and baseplates. It is explicitly stated as for "additive manufacturing" of these dental prosthetics, which is a manufacturing process, not a diagnostic one. Its intended use focuses on creating a physical product to replace or repair dental structures, not on identifying a disease or condition.
No
The device is a light-curable polymerizable resin, which is a physical material used in additive manufacturing, not a software program.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for the "fabrication and repair, by additive manufacturing, of full and partial removable dentures and baseplates." This describes a manufacturing process for a medical device (dentures), not a diagnostic test performed in vitro (outside the body) on biological specimens to provide information about a patient's health.
- Device Description: The description details a light-cured resin used in a dental setting for creating physical dental prosthetics. This aligns with a material used in manufacturing, not a diagnostic tool.
- Lack of Diagnostic Elements: There is no mention of analyzing biological samples, detecting biomarkers, or providing diagnostic information about a patient's condition.
- Performance Studies: The performance studies focus on the physical and chemical properties of the resin (flexural strength, water sorption, shade match, printing accuracy, biocompatibility), which are relevant to the material's suitability for creating a physical device, not its diagnostic capabilities.
IVD devices are specifically designed to perform tests on samples like blood, urine, tissue, etc., to diagnose diseases, monitor health, or screen for conditions. This device is a material used to create a medical device (dentures), which is a different category of medical product.

Visual Shade Match and Lab Shade Verification: Visual shade match and Lab shade verification were performed on samples of the G1, G3 and G4 shade within a batch and between batches. The results met the acceptance criteria and conformed that the subject device, Glidewell™ 3DP Denture Base Resin, met the color accuracy and consistency requirements for all its different shades.
Printing Accuracy and Printing Orientation Validation: Printing accuracy test was performed to validate that the physical output of the additive manufacturing system and procedure for Glidewell™ 3DP Denture Base Resin is able to meet design input dimensions within the pre-specified tolerance. Printing orientation test was performed to validate that the subject device, Glidewell™ 3DP Denture Base Resin, printed at different print direction within the build space relative to the device orientation and at different build plate locations are able to meet the same performance criteria. The results met the pre-specified acceptance criteria and demonstrated that the subject device, Glidewell™ 3DP Denture Base Resin, can be reliably fabricated at different print directions within the build space and at different build plate locations using the additive manufacturing system and procedure.
Packaging Validation: Packaging validation was also performed for the subject device, Glidewell™ 3DP Denture Base Resin. Per ASTM D4169-14, the shipping unit was tested for manual handling, compressive loads, repetitive shocks from vibration, vertical vibration environments. concentrated impacts and secondary manual handling drops. After the tests, the shipping containers were visually inspected for any damages. It was determined that Glidewell™ 3DP Denture Base Resin with its respective packaging, is suitable for use.
Biocompatibility: Biological evaluation within a risk management process was performed in accordance with ISO 10993-1:2018 and ISO 14971:2019. Based on the biocompatibility testing results, it was determined that there is no biocompatibility concern for the subject device, Glidewell™ 3DP Denture Base Resin, for its intended use with regard to cytotoxicity, skin sensitization, oral mucosal irritation, genotoxicity, subchronic toxicity, subacute systemic toxicity or systemic (acute) toxicity.
