Patient-specific abutment design parameters:
The provided text describes the 510(k) submission for ARUM DENTISTRY Co., Ltd.'s "Customized Abutment." This is a Class II medical device (dental implant abutment). The document focuses on demonstrating substantial equivalence to a predicate device, which is a common pathway for FDA clearance.
Here's a breakdown of the requested information, based on the provided text. It's important to note that many of the typical "acceptance criteria" and "study proves that the device meets the acceptance criteria" details for AI/ML devices, such as those related to accuracy, sensitivity, specificity, or reader studies, are not applicable to this type of device. This is a physical, custom-fabricated medical device (dental abutment), not an AI/ML-driven diagnostic or treatment planning system. Therefore, the "acceptance criteria" here refer to performance testing (mechanical, biocompatibility, sterilization) to ensure the device is safe and effective and substantially equivalent to a predicate. The study that proves it meets criteria is the testing performed.
1. Table of Acceptance Criteria and Reported Device Performance
| Acceptance Criteria Category | Specific Acceptance Criteria (Standards/Tests) | Reported Device Performance (Summary) |
|---|---|---|
| Material | Ti-6Al-4V Eli conforming to ASTM F136 | Device fabricated from Ti-6Al-4V Eli conforming to ASTM F136. |
| Sterilization | ISO 17665-1, ISO 17665-2, and ISO 14937 | Sterilization validation performed for predicate and leveraged. Device is provided non-sterile (steam sterilization by user). |
| Biocompatibility | ISO 10993-5 and ANSI/AAMI ST72 | Biocompatibility testing performed for predicate and leveraged. |
| Mechanical Performance | ISO 14801 (Static and Fatigue Testing) | Worst-case constructs subjected to static compression and compression fatigue testing. Results met the criteria of the standard, demonstrating substantial equivalence. |
| MRI Environment Safety | Scientifically reviewed (published literature, FDA Guidance) for magnetically induced displacement force and torque | Non-clinical worst-case MRI review performed using scientific rationale and published literature. Rationale addressed parameters per the FDA Guidance, concluding safety. |
2. Sample Size Used for the Test Set and the Data Provenance
- Test Set Sample Size: The document does not specify a numerical "sample size" in terms of number of abutments tested for mechanical performance. It refers to "worst-case constructs" for each compatible implant line. This is typical for mechanical testing where a representative "worst-case" configuration is tested to demonstrate the device's limits.
- Data Provenance: The testing data is derived from non-clinical performance tests (mechanical testing, sterilization validation, biocompatibility) of the device and its predicate. The origin of the raw data (e.g., specific lab, country) is not detailed, but it is implied to be internal or from a contract testing lab as part of the manufacturer's quality system. It is prospective for the specific tests performed to support this submission.
3. Number of Experts used to establish the ground truth for the test set and the qualifications of those experts
- This is not applicable to this type of medical device submission. Ground truth (in the AI/ML sense) is not established by human experts for mechanical/biocompatibility testing. The "ground truth" for proving the device meets acceptance criteria relies on the results of standardized engineering and biological tests conducted according to recognized standards (e.g., ISO, ASTM).
4. Adjudication method for the test set
- Not applicable. There is no human adjudication process involved in interpreting the results of mechanical, biocompatibility, or sterilization tests for this device. The results are compared directly to pre-defined criteria in the standards.
5. If a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was done
- No, an MRMC study was not done. This type of study is relevant for diagnostic imaging devices where human readers interpret medical images with and without AI assistance. This is a physical, custom-fabricated dental device, so such a study is not applicable.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done
- Not applicable. This device is not an algorithm. Performance evaluation for this device is based on physical and material properties, not algorithmic output.
7. The type of ground truth used
- The "ground truth" for this device's performance is established by objective, standardized test methods (e.g., stress-strain measurements for mechanical testing, biological assays for biocompatibility, sterility indicator results for sterilization). It is based on engineering and scientific standards rather than expert consensus on medical images or pathology.
8. The sample size for the training set
- Not applicable. This device is not an AI/ML or software device that undergoes "training." Its design and manufacturing are based on established engineering principles for dental abutments.
9. How the ground truth for the training set was established
- Not applicable, as there is no "training set" for this type of device. The "ground truth" for its development and validation relies on adherence to design specifications, material standards, and validated manufacturing processes.

MR Environment Condition
Non-clinical worst-case MRI Review was performed to evaluated the metallic. The Customized Abutment in the MRI environment using scientific rationale and published literature (e.g., Woods, Terry 0., Jana G. Delfino, and Sunder Rajan. 'Assessment of Magnetically Induced Displacement Force and Torque on Metal Alloys Used in Medical Devices." Journal of Testing and Evaluation 49.2 (2019): 783-795)., based on the entire system including all variations (all compatible implant bodied, dental abutments and, fixation screws) and material composition. Rationale addressed parameters per the FDA Guidance "Testing and Labeling Medical Devices for Safety in the Magnetic Resonance (MR) Environment," including magnetically induced displacement force and torque.
Non-Clinical Test Data
No need to perform any new additional non-clinical testing for the subject device since the subject device compared to predicate device are substantially equivalent in indications, fundamental technology, material and design. The predicate device may be leveraged for the subject devices because of using the same materials, manufacturing methods, and sterilization procedures. Although the dimensions are slightly different, it doesn't impact product's safety and effectiveness because the predicate device is the worst case based on the product's dimensional comparison analysis provided.
Below tests were performed for primary predicate and leveraged for the subject device:
- . Sterilization validation according to ISO 17665-1. ISO 17665-2, and ISO 14937 referenced in K193425.
- Biocompatibility according to ISO 10993-5 and ANSI/AAMI ST72 referenced with K193425. .
Non-clinical performance data submitted to demonstrate substantial equivalence included:
- . Static and fatigue testing according to ISO 14801. No clinical data is included in this submission.
The results of the above tests have met the criteria of the standards and demonstrated the substantial equivalence with the primary predicate.
Equivalence to Marketed devices
Mechanical performance testing was performed according to ISO 14801. For each compatible implant line, worst-case constructs were subjected to static compression and compression fatigue testing. Minor differences in the designs, dimensions, sizes, or compatible implant lines among the subject device, the primary predicate device, and the reference devices do not affect substantial equivalence. These minor differences do not impact substantial equivalence

because these differences are related to the compatible implant designs, or are mitigated by the mechanical performance testing.
Conclusion
The Customized Abutment 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, the Customized Abutment and its predicates are substantially equivalent.
