Intended Use

Additively Manufactured Denture Resin is a light-cured resin indicated for the fabrication of all types of denture bases, for instance full and partial removable dentures.

Additively Manufactured Denture Resin is intended for continuous use in the oral environment, exclusively for professional dental work.

Additively Manufactured Denture Resin can be used in combination with a DLP 3D printers utilizing wavelengths at 385nm or 405nm. A 3D-printer is not part of the device.

Device Description

Additively Manufactured Denture Resin is a light-cured one-component materials for dental professional use only and intended for the fabrication of full and partial removable dentures. This Product is a liquid photo-curable material that is polymerized, by the photo-initiator contained in the resin. For use in Digital Light Processing (DLP)-3D printers utilizing wavelengths at 385nm or 405nm. The specifications of this product are divided into 500g, 1000g, 5kg and 10kg according to the weight of the resin liquid.

2. Sample size used for the test set and the data provenance:

The document states "Bench Testing: Physical and mechanical properties of the subject device were evaluated according to FDA-recognized version ISO 20795-1 Dentistry - Base polymers - Part 1: Denture base polymers." It also mentions "Biocompatibility Testing was performed according to FDA currently-recognized versions of biocompatibility consensus standards..."

However, the specific sample sizes for these tests are not provided in the document. The data provenance is related to laboratory bench testing and biocompatibility testing, indicating a controlled laboratory environment rather than direct patient data. The origin of the testing (e.g., country) is not specified beyond the manufacturer being from China.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

This information is not applicable in this context. The document describes the testing of a material's physical, mechanical, and biological properties against established international standards (ISO 20795-1, ISO 10993 series). Ground truth in this case is defined by these standards and the protocols for carrying out the tests, rather than by expert consensus on clinical cases.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:

This is not applicable. The testing involves objective measurements against predefined criteria in laboratory settings, not clinical interpretation requiring adjudication.

5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance:

This is not applicable. The device is a "Denture Resin," a material used for fabricating dental prostheses, not an AI or imaging diagnostic tool that would involve human readers or AI assistance.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

This is not applicable. The device is a material, not a software algorithm.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.):

The ground truth for the performance claims for the denture resin is based on established material science standards and biocompatibility guidelines (ISO 20795-1, ISO 10993, ISO 7405). These standards define the test methods and acceptance limits for various physical, mechanical, and biological properties.

8. The sample size for the training set:

This is not applicable. The device is a material product, not a machine learning model that requires a training set.

9. How the ground truth for the training set was established:

This is not applicable as there is no training set for this type of device.
