It uses continuous gentle force to adjust tooth position, correct malocclusion, and maintain the results of completed orthodontic treatment.

    It can also be used for printing splints and night guards.

    Device Description

    Additively Manufactured Aligner Resin is custom plastic aligner system which are a series of doctor prescribed clear removable aligners that are used as alternative treatment for the alignment of maloccluded or misaligned teeth. This series of aligners gently move the patient's teeth in small increments from their original state to a treated state.

    Additively Manufactured Aligner Resin is a light-curing resin used to print orthodontic appliances. The resin is a light yellow transparent liquid. The appliance printed by a 3D printer is de-supported, cleaned and post-cured to obtain an orthodontic appliance that can correct the patient's malocclusion. This product is a light-curing 3D printing resin composed of acrylate resin oligomers and acrylate monomers as well as initiators and additives.

    Additive manufacturing (light cured) orthodontic resin is a light cured acrylic resin commonly used in the manufacture of orthodontic appliances. The resin is stored in a black HDPE bottle according to the weight of the resin liquid. The color of the resin is colorless or yellowish liquid, polymerized by UV light at 385 nm or 405 nm.

    AI/ML Overview

    The provided FDA 510(k) clearance letter details the clearance of an "Additively Manufactured Aligner Resin." This document is for a material, not a diagnostic AI device. Therefore, the information typically requested in a description of an AI device's acceptance criteria and study proving its performance (e.g., sample sizes for test and training sets, number of experts establish ground truth, MRMC studies, standalone performance) is not applicable to this submission.

    The acceptance criteria and supporting studies for this material device primarily focus on bench testing (physical and mechanical properties), biocompatibility, sterility, and shelf-life. The purpose of these tests is to demonstrate that the new aligner resin is safe and effective for its intended use, comparable to already marketed predicate devices.

    Here's an interpretation of the relevant information provided:


    Acceptance Criteria and Performance of "Additively Manufactured Aligner Resin"

    As this is a material device, the "acceptance criteria" are based on meeting established international standards for dental materials and demonstrating comparable or superior performance to existing predicate devices. The "study that proves the device meets the acceptance criteria" refers to the non-clinical bench testing, biocompatibility testing, and shelf-life testing performed.

    1. Table of Acceptance Criteria and Reported Device Performance

    The primary standard referenced for mechanical characteristics is ISO 20795-2:2013 Dentistry – Base polymers – Part 2: Orthodontic base polymers. The acceptance criteria for each property are implicitly defined by the requirements of this standard, and the device's performance is reported as meeting these requirements or being comparable to predicate devices.

    Acceptance Criteria CategorySpecific Performance CharacteristicRequired Standard / Predicate Range (Acceptance Criteria)Reported Device Performance (Subject Device)Result
    Mechanical Properties (ISO 20795-2:2013)HomogeneityMeets ISO 20795-2:2013 requirementsSimilar to predicateMet

    GenotoxicityMeets ISO 10993-3 requirementsAddressedMet
    Shelf-LifeUnopened Shelf LifeDemonstrated stability for 2 years2 yearsMet
    Opened Shelf LifeDemonstrated stability for 60 days60 daysMet

    *Note: For Flexural Modulus and Ultimate Flexural Strength, the subject device's performance was statistically significantly higher than the predicate, which is considered an improvement and not an adverse difference in terms of safety or effectiveness for the material properties. For Water Solubility and Sorption, slight differences were observed but all conformed to the ISO standard.

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

    The document does not specify the exact sample sizes for each mechanical property test (e.g., number of specimens tested for flexural strength). This level of detail is typically found in the full testing report, not the 510(k) summary. However, tests were conducted as "bench testing" meaning in a laboratory setting. The data provenance is implied to be from the manufacturer's internal testing facilities, Aidite (Qinhuangdao) Technology Co., Ltd., which is based in China. The testing is retrospective in the sense that it's pre-market validation performed on manufactured material samples.

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

    This question is not applicable as this is a material device and not an AI or diagnostic device that requires expert-established ground truth for a test set. Ground truth for material properties is established by objective physical and chemical testing methods adhering to international standards (e.g., ISO, ASTM).

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

    This question is not applicable as there is no human interpretation or subjective assessment being performed that would require an adjudication method. The testing results are quantitative measurements.

    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 question is not applicable. An MRMC study is relevant for diagnostic AI devices where human readers (e.g., radiologists) interpret images with and without AI assistance. This submission is for a dental material.

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

    This question is not applicable. There is no algorithm or software for standalone performance evaluation in this material device submission.

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

    The "ground truth" for this material device is established by objective, standardized laboratory testing methods against pre-defined specifications and international material standards (e.g., ISO 20795-2:2013). This is analogous to a "gold standard" for material properties.

    8. The sample size for the training set

    This question is not applicable. This is a material device, not an AI/machine learning model, and therefore does not have a "training set" in the computational sense.

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

    This question is not applicable for the same reason as point 8.

    Intended Use

    Biomic Color Opaque is liquid used for coloring pre-sintered zirconia restorations. It is used for the internal surface of dental zirconia material prosthesis.

    Device Description

    Biomic Color Opaque is a liquid primarily composed of Methylacryloyl propyl trimethoxy silane, deionized water, 1, 3-butanediol, ferric chloride, citric acid, cerium nitrate, erbium nitrate, cobaltous nitrate, manganous acetate, and aluminum nitrate.

    This product is designed for use on the internal surface of dental zirconia material prostheses. It penetrates tightly with the zirconia surface, forming an extremely thin shade layer that reduces the internal surface permeability of the zirconia material prosthesis. The devices are intended to be used solely by dental technicians for the fabrication of zirconia restorations for individual dental patients.

    For staining, the zirconia materials must be immersed into the staining solution or brushed with the liquid before sintering at high temperature. The staining solution consists of two components: Type I - a color component (A、B、C、D、W、L、M、R、S、X), and Type II - an OP component, 1:1 collocation is recommended. These components are mixed together for use on the zirconia material to achieve the desired shade.

    AI/ML Overview

    The provided FDA 510(k) clearance letter and its accompanying summary for the "Biomic Color Opaque" device do not contain information about clinical studies or performance data related to AI/algorithm-driven performance, ground truth establishment, or multi-reader multi-case (MRMC) studies.

    The document explicitly states under Section 7.0, "Summary of Clinical Test," that "Clinical testing was not required for this submission." This indicates that the device's clearance was based on non-clinical data (bench testing, biocompatibility, sterility, shelf-life) and a comparison to a predicate device, not on AI/algorithm performance. The device itself is a "Porcelain Powder For Clinical Use" (specifically a pre-sintered zirconia coloring liquid), not an AI-driven diagnostic or image analysis tool.

    Therefore, it is impossible to provide the requested information regarding acceptance criteria, study details, sample sizes, expert involvement, and ground truth for an AI/algorithm-driven study based solely on the provided text.

    However, I can extract the acceptance criteria and performance related to the physical and chemical properties of the device, as that is the type of testing described.

    Here's a summary of the acceptance criteria and performance as described for this specific device (a coloring liquid), not for an AI algorithm:

    AI/ML Overview

    The provided FDA 510(k) clearance letter and summary describe a dental resin, not an AI/software as a medical device (SaMD). Therefore, the information required for explaining AI/SaMD acceptance criteria and studies (such as diagnostic performance metrics, reader studies, ground truth establishment, training/test set details, etc.) is not present in this document.

    The document focuses on the physical, mechanical, and biocompatibility properties of a dental manufacturing resin. As such, I cannot extract the requested information regarding AI/SaMD performance studies from this provided text.

    Here's a breakdown of why the requested information cannot be provided based on the input:

    • Device Type: The device, "Additive Manufacturing (Light Curing) Crown Bridge Resin," is a material used for 3D printing dental restorations. It is not an AI algorithm or software.
    • Study Type: The studies performed are bench tests (Non-clinical Test Conclusion) evaluating material properties (e.g., flexural strength, water sorption, biocompatibility) against established ISO standards, and shelf-life testing. These are not studies to prove the performance of an AI model.
    • Acceptance Criteria & Performance: The acceptance criteria are explicitly tied to physical and mechanical properties (e.g., Flexural Strength ≥ 50 MPa as per ISO 10477:2020), not diagnostic accuracy or other AI-related metrics.
    • Missing Information Related to AI/SaMD: All specific points requested in your prompt (sample size for test/training sets, experts for ground truth, adjudication methods, MRMC studies, standalone performance, type of ground truth, effect size) are entirely absent because they are not applicable to the clearance of a dental resin material.

    In summary, the provided document does not contain the information necessary to describe the acceptance criteria and study that proves an AI/SaMD device meets its acceptance criteria. The document pertains to a physical dental material, not an artificial intelligence product.

    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.

    This document describes a traditional dental material. The performance data presented are for material properties, not an AI/ML algorithm.

    Here's why many of your detailed questions cannot be answered by this document:

    • AI/ML Device: This is not an AI/ML device. It's a physical material used for fabricating dentures.
    • Acceptance Criteria for AI Performance: The acceptance criteria are for physical material properties as defined by ISO standards, not for AI metrics like sensitivity, specificity, AUC, or F1-score.
    • Sample Size for Test Set (AI): There's no AI test set. Instead, there are samples of the material tested for its physical and chemical properties.
    • Data Provenance (AI): Not applicable. The "data" are laboratory measurements of material properties.
    • Experts for Ground Truth (AI): Not applicable. Ground truth for material properties is established through standardized laboratory testing methods.
    • Adjudication Method (AI): Not applicable.
    • MRMC Study (AI): Not applicable. This refers to human reader performance with/without AI assistance for diagnostic tasks, which is irrelevant here.
    • Standalone Performance (AI): Not applicable.
    • Type of Ground Truth (AI): For this device, "ground truth" refers to the measured physical and chemical properties of the material against established standards (e.g., ISO, FDA guidance).
    • Training Set (AI): Not applicable. This device is not developed using machine learning.
    • Ground Truth for Training Set (AI): Not applicable.

    Based on the provided document, here's what can be extracted regarding the "acceptance criteria" (which are performance specifications for the material) and its "study" (which are non-clinical bench tests):

    1. Table of Acceptance Criteria and Reported Device Performance

    The acceptance criteria are implicitly defined by the relevant ISO standards (ISO20795-1: 2013, ISO 4049: 2019, ISO 7491: 2000) and the comparison to the predicate device. The performance data demonstrate compliance with these standards and substantial equivalence.

    Other Performance Bench TestsMeet all design specifications and relevant ISO standards (Surface characteristics, Shape capability, Colour, Colour stability, Translucency, Freedom from porosity, Bonding to synthetic polymer teeth)Complies with ISO standardsComplies with ISO standards

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

    • Sample Size: The document does not specify the exact sample sizes for each bench test conducted (e.g., how many specimens for flexural strength). It generally states that "Performance testing were conducted to verify that the subject device met all design specifications." Specific sample sizes would be detailed in the full test reports, which are not part of this summary.
    • Data Provenance: The tests are non-clinical bench tests performed in a laboratory setting, presumably by the manufacturer (Aidite (Qinhuangdao) Technology Co., Ltd) or a contracted lab. The country of origin for the data is implicitly China, as the manufacturer is based there. The data are retrospective in the sense that they were collected prior to the submission.

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

    • Not applicable as this is not an AI/ML device requiring expert interpretation for ground truth. The "ground truth" for material properties is established through standardized and validated laboratory testing procedures as per ISO standards.

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

    • Not applicable. This concept applies to human reader studies often seen with diagnostic AI/ML devices, not material property testing.

    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:

    • No, an MRMC comparative effectiveness study was not done. This is not an AI/ML device.

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

    • No, a standalone algorithm performance study was not done. This is not an AI/ML device.

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

    • The "ground truth" for this device's performance is derived from standardized laboratory measurement methods as described in the cited ISO standards (e.g., ISO20795-1 for denture base polymers, ISO 4049 for polymer-based restorative materials, ISO 7491 for color stability) and biocompatibility testing according to ISO 10993-1. Comparison is also made to the performance characteristics of the predicate device.

    8. The sample size for the training set:
