Dentium Prosthetics are intended for use as an aid in prosthetic rehabilitation.
The purpose of this submission is to expand the Dentium Prosthetics to include the Scan Abutments and Comfort Caps.
Scan Abutments are used provisionally as an accessory to endosseous dental implant during healing period to prepare gingival tissue for acceptance of a final abutments are designed to aid in soft tissue contouring the healing period after implant placement, creating an emergence profile for the final abutment.
Comfort Caps are used provisionally as an accessory to protect the dental abutment before final prosthesis.
They have the design feature that enable to transmit position and angulation data of implant when taking a digital impression using an intra-oral scanner.
The Scan Abutments and Comfort Caps are prefabricated and made of Ti-6AI-4V ELI (ASTM F136) or PEEK(ASTM F2026). Scan Abutments are compatible with Dentium Implant(K041368 Implantium and K160965 SuperLine or K153268 NR Line) and Comfort Caps are compatible with Dentium Prosthetics(K052957 Implantium and K172640 SuperLine or K153268 NR Line)
This document is a 510(k) Pre-Market Notification from the FDA regarding dental devices (Scan Abutments and Comfort Caps). It focuses on demonstrating substantial equivalence to previously cleared devices, rather than establishing performance against specific acceptance criteria for a novel AI/ML device.
Therefore, many of the requested details about acceptance criteria and study design (especially those related to AI/ML performance, ground truth, human readers, and training/test set specifics) are not applicable to this type of regulatory submission.
Here's what can be extracted and what cannot:
1. A table of acceptance criteria and the reported device performance:
- Acceptance Criteria (Implicit for 510(k) Substantial Equivalence): The primary "acceptance criterion" for a 510(k) is the demonstration of substantial equivalence to a legally marketed predicate device. This is achieved by showing that the new device has the same intended use as a predicate and the same technological characteristics, or different technological characteristics that do not raise different questions of safety and effectiveness and are as safe and effective as the predicate.
- Reported Device Performance (as demonstrated for Substantial Equivalence):
- Indications for Use: The subject device has the same indication for use as the primary predicates: "Dentium Prosthetics are intended for use as an aid in prosthetic rehabilitation."
- Technological Characteristics Comparison (Tables provided in Section 7): The document provides detailed comparison tables for Scan Abutments (vs. K172640, K153268, K173374, K172160) and Comfort Caps (vs. K171142, K172160). These tables demonstrate similarities in:
- Device name, Manufacturer, 510(k) Number (where applicable)
- Indication for use
- Materials (Ti-6Al-4V ELI, PEEK – demonstrated to be identical to or commonly used in predicates)
- Form (Preformed)
- Sterilization (Non-sterile, similar to primary predicates; note on sterile reference predicates)
- Use (Prescription)
- Single Use Only (Yes)
- Design characteristics: Diameter, Length, Connection type, Scanning feature (for Scan Abutments), Surface treatment.
- Performance Data (Non-clinical):
- Steam sterilization validation (ISO 17665-1 and ISO 17665-2), demonstrating a sterility assurance level (SAL) of 10-6. (This is a specific performance metric).
- Biocompatibility of Ti-6Al-4V ELI (ASTM F136) was demonstrated by referencing a previous submission (K172640) using the same materials and manufacturing processes.
- Cytotoxicity testing of PEEK (ASTM F2026) was performed according to ISO 10993-5.
N/A (Not Applicable) for this type of submission:
- 2. Sample sized used for the test set and the data provenance (e.g. country of origin of the data, retrospective or prospective): No specific "test set" in the context of an AI/ML model for performance evaluation is described. The performance data relates to material properties and sterilization, not diagnostic/AI performance on a dataset.
- 3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. Ground truth for an AI/ML model is not a concept for these mechanical/material devices.
- 4. Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not applicable.
- 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: Not applicable. This device is not an AI/ML diagnostic tool.
- 6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable.
- 7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.): Not applicable. The "ground truth" here is compliance with material standards, sterilization standards, and functional equivalence to predicates.
- 8. The sample size for the training set: Not applicable.
- 9. How the ground truth for the training set was established: Not applicable.
In summary, this FDA document is for a medical device (dental abutments and caps) seeking 510(k) clearance based on substantial equivalence. It does not involve AI/ML components or comparative effectiveness studies of human readers, thus many of the questions are not relevant.

Dear Byung-sun Kim:
This letter corrects our substantially equivalent letter of November 4, 2019.
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
{1}------------------------------------------------
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies. You must comply with all the Act's requirements, including, but not limited to: registration and listing (21 CFR Part 807); labeling (21 CFR Part 801); medical device reporting of medical device-related adverse events) (21 CFR 803) for devices or postmarketing safety reporting (21 CFR 4, Subpart B) for combination products (see https://www.fda.gov/combination-products/guidance-regulatory-information/postmarketing-safety-reportingcombination-products); good manufacturing practice requirements as set forth in the quality systems (QS) regulation (21 CFR Part 820) for devices or current good manufacturing practices (21 CFR 4, Subpart A) for combination products; and, if applicable, the electronic product radiation control provisions (Sections 531-542 of the Act); 21 CFR 1000-1050.
Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21 CFR Part 807.97).
