More Information

No
The summary describes a dental implant abutment, a physical device, and there is no mention of software, algorithms, or any terms related to AI/ML.

Yes
The device is used to support and maintain prosthetic restored teeth, which directly addresses a health condition (loss of teeth) by restoring function and aesthetics, qualifying it as a therapeutic device.

No
The device is described as an abutment for dental implants, used to support and maintain prosthetic teeth. Its intended use is for restoration, not for diagnosis of a condition.

No

The device description explicitly states it is a "material for dental surgery" and an "abutment," which are physical components, not software. The performance studies also focus on material properties and physical testing.

No, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • IVD Definition: In Vitro Diagnostics are medical devices used to perform tests on samples taken from the human body (like blood, urine, tissue) to provide information about a person's health.
  • Device Description: The Oneday Implant Abutment is a physical material used in dental surgery to support prosthetic teeth. It is implanted into the jawbone.
  • Intended Use: The intended use is to support dental restorations in the mouth, not to analyze biological samples.
  • Lack of IVD Characteristics: The provided information does not mention any testing of biological samples, analysis of bodily fluids, or diagnostic purposes. The performance studies focus on mechanical properties, sterilization, biocompatibility, and MRI compatibility, which are typical for implantable devices, not IVDs.

Therefore, based on the provided information, the Oneday Implant Abutment is a dental implant component, not an In Vitro Diagnostic device.

Non-Clinical Test Data

Below tests were performed on subject device:

  • . Fatigue Testing under the worst-case scenario according to ISO 14801:2016
  • End User Sterilization Validation Test Report on Abutments according to ANSVAAMI ST79. . ISO 17665-1, ISO 17665-2, ISO 11737-1, ISO 11737-2, and ISO 11138-1

Below tests were performed on a worst-case test article with the same material composition, manufacturing, and sterilization and leveraged for the subject device:

  • . Biocompatibility testing on Abutments made with Ti-6Al-4V ELI according to ISO 10993-1:2009, ISO 10993-3:2014, ISO 10993-5:2009, ISO 10993-6:2007, ISO 10993-10:2010 and ISO 10993-11:2006
    The results of the above tests have met the criteria of the standards and demonstrated the substantial equivalence with the predicate device.

The end user sterilization test was performed on abutment that is not cleared but it can be leveraged for the subject device because the product category, material, manufacturing process, facility, and packaging of the both products are exactly same.

The Biocompatibility Test was conducted on abutment made of Ti-6AI-4V ELI and leveraged for the subject device because both products are manufactured with same materials and manufacturing process. It demonstrates that the subject device is biocompatible and substantial equivalence with the predicate.

The Fatigue Testing was performed under worst case scenario according to ISO 14801.

MR Environment Condition

Non-clinical worst-case MRI review was performed to evaluate the metallic devices in the MRI environment using scientific rationale and published literature (e.g., Woods, Terry O., 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 bodies, 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.

Clinical testing was not necessary to establish substantial equivalency of the device.

Conclusion

Oneday Implant 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, Oneday Implant Abutment and its predicates are substantially equivalent.
