· Lucitone Digital Print™ 3D Denture Base is a light-cured resin indicated for the fabrication of denture bases including full and partial dentures* and implant overdentures.
· Lucitone Digital IPN™ 3D Premium Tooth is a light-cured resin intended for printing denture teeth. Lucitone Digital Value™ 3D Economy Tooth & Trial Placement is intended for use as:
· Printing resin for fabricating removable dentures for try-in and evaluation prior to fabrication of the final denture.*
· Printing resin for fabricating a temporary denture.
· Printing resin for fabricating denture teeth in full arches and segments that will subsequently be fused into a denture base.
· Printing resin for fabricating provisional crowns, bridges.**
• Lucitone Digital Fuse™ Step 1 – 3D Tooth Conditioning Agent is indicated for use in enhancing the bond of denture teeth to denture base and denture base to denture base.
· Lucitone Digital Fuse™ Step 2 - 3D Denture Bonding Resin is utilized as an aid in bonding denture teeth to denture base as well as repair using traditional techniques.
· Lucitone Digital Fuse™ Step 3 – Total 3D Sealer is a light-cured sealant that produces a smooth, glossy surface finish on the denture.
*Partial and full dentures are replacement for patients with missing teeth.†

Lucitone Digital Value™ (LDV) 3D Economy Tooth & Trial Placement, which is part of the Lucitone Digital Print™ Denture (LDPD) System, is a methacrylate-based resin system which is used to fabricate dental prostheses using an additive printer and computer aided design and computer aided manufacturing (CAD/CAM) technologies.
I am sorry, but the provided text does not contain the detailed information necessary to answer your request about acceptance criteria and the study that proves the device meets them. The document is an FDA 510(k) summary for a dental device (Lucitone Digital Print Denture™ System) that describes the device, its indications for use, and a few performance tests.
Specifically, the following information is not present in the text:
- A comprehensive table of acceptance criteria and reported device performance. While some performance metrics are listed (Flexural Strength, Flexural Modulus, Water Sorption, Water Solubility), these are general and not presented as specific acceptance criteria with corresponding performance test results. For example, for "Flexural Strength," it only states "≥50 MPa" as the acceptance criterion, but it does not report the actual performance value obtained for the subject device.
- Sample size used for the test set and data provenance. The document only mentions "In all instances, the subject device functioned as intended and all test results observed were as expected," without providing details about the test set.
- Number of experts used to establish ground truth and their qualifications.
- Adjudication method.
- If a multi-reader multi-case (MRMC) comparative effectiveness study was done, or the effect size of human improvement with AI assistance. This device is a denture system, not an AI or diagnostic tool, so an MRMC study is highly unlikely to be relevant.
- If a standalone (algorithm only without human-in-the-loop performance) study was done. This is not applicable to a physical dental device.
- The type of ground truth used. This is not applicable in the context of a physical materials performance study.
- Sample size for the training set. This is not applicable as it's not an AI model.
- How the ground truth for the training set was established. This is not applicable as it's not an AI model.
The document mainly focuses on demonstrating substantial equivalence to a predicate device through non-clinical performance data (material properties) and biocompatibility, rather than a clinical study evaluating diagnostic or treatment efficacy that would typically involve test sets, ground truth, and expert adjudication. The "Performance Data" section explicitly states, "Clinical and Pre-clinical testing were not necessary to demonstrate equivalence."
§ 872.3760 Denture relining, repairing, or rebasing resin.
(a)
Identification. A denture relining, repairing, or rebasing resin is a device composed of materials such as methylmethacrylate, intended to reline a denture surface that contacts tissue, to repair a fractured denture, or to form a new denture base. This device is not available for over-the-counter (OTC) use.(b)
Classification. Class II.
