IS Multi Unit Abutment System is intended for use with a dental implant to provide support for prosthetic restorations such as bridges.
IS Multi Unit Abutments are premanufactured dental implant abutments directly connected to the endosseous dental implant with internal hex connections (multiple tooth). IS Multi Unit Abutment System is made of Titanium ELI according to ASTM F136.
IS Multi Unit Abutment System is composed of IS Multi Unit Abutment, IS Multi Unit Angled Abutment, Multi Unit Abutment Cylinder, Multi Unit Healing Cap, Multi Unit Temporary Cylinder, IS Multi Unit Angled Abutment Screw and Cylinder Screw.
All Multi-Unit Abutments (Straight/Angled) are intended only for multi-unit loaded restoration.
I am sorry, but the provided text does not contain information about the acceptance criteria and the study that proves a device meets them in the context of an AI/ML medical device.
The document is a 510(k) premarket notification for a dental implant abutment system (IS Multi Unit Abutment System) and focuses on demonstrating substantial equivalence to predicate devices, which is a regulatory pathway for traditional medical devices, not typically AI/ML-driven ones.
Therefore, I cannot provide the requested information, including:
- A table of acceptance criteria and reported device performance.
- Sample size used for the test set and data provenance.
- Number and qualifications of experts for ground truth.
- Adjudication method.
- MRMC comparative effectiveness study results.
- Standalone performance.
- Type of ground truth used.
- Sample size for the training set.
- How ground truth for the training set was established.
The document primarily details device descriptions, indications for use, material specifications, and comparisons to predicate devices in terms of physical characteristics and intended use. It also mentions non-clinical testing data related to sterilization and fatigue testing for the physical dental device components.

Dear April Lee:
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).

{10}------------------------------------------------
Similarities:
IS Multi Unit Abutment System has same device characteristics with the Primary predicate devices, OSSTEM Implant System-Abutment (K161689) and commercially available products based on the indications for use, the technology used, the material composition employed and performance characteristics as predicate devices. The subject device has been supposed to performance and product validations prior to release. Testing including performance and fatigue test has been finished to ensure the devices comply with the applicable International standards and US FDA Guidance.
Differences:
There are differences in Indications for Use, design, cuff length and surface treatment between the subject device and primary predicate.
- Indications for Use: The subject device doesn't include the "O-ring" as the component; therefore, it is not intended to use for overdenture. As the indications for use of the subject device are in range of the predicate's, it doesn't affect the substantial equivalence.
- Design, Cuff length, and Surface treatment: To support Ø4.8X6.0mm of subject abutment and surface treatment, K182194 and K120530 were added as the reference device. These differences don't affect product's fundamental functions and substantial equivalence.
Non-clinical testing data:
The subject device was tested to evaluate its substantial equivalence according to the following standards.
- End User Sterilization Validation Test Report on IS Multi Unit Abutment Angled Abutment ● (Hex type) according to ANSI/AAMI ST79, ISO 17665-1, ISO 17665-2, ISO 11737-1, ISO 11737-2, and ISO 11138-1
- . Fatigue Test Report according to ISO 14801:2016
Below tests were performed for predicate devices and leveraged for the subject device:
- Sterilization Validation Test on Healing Abutments according to ISO 11137-1,2,3 referenced in K181138
- Shelf-Life Test on Healing Abutments according to ASTM F1980 referenced in K181138
- Biocompatibility Test according to ISO 10993-1 referenced in K181138
- Bacterial Endotoxin Testing on Healing Abutments according to ANSI/AAMI ST72:2011, USP ● <161>, and USP <85>, referenced in K181138
The results of the above tests have met the criteria of the standards, and demonstrated the substantial equivalence with the predicate device.
The non-clinical testing results demonstrate that the subject device is substantially equivalent to the predicate device.
Conclusion
IS Multi Unit Abutment System constitutes a substantially equivalent medical device, meeting all the declared requirements of its intended use. This system has the same intended use and fundamental scientific technology as its predicate devices. Therefore, IS Multi Unit Abutment System and its predicates are substantially equivalent.
