The summary describes a CAD/CAM process for designing and milling dental abutments based on clinician prescription and patient-matching parameters. There is no mention of AI or ML being used in the design or manufacturing process. The performance studies focus on mechanical fatigue, biocompatibility, sterilization, and compatibility, not on the performance of any AI/ML algorithm.
No
The device is described as an aid in prosthetic rehabilitation, specifically a patient-specific abutment for dental implants, which serves a restorative rather than a therapeutic function.
No
Explanation: The device, PreXolid CAD/CAM Abutments, is described as an aid in prosthetic rehabilitation on dental implants. Its function is to support a dental prosthesis, not to diagnose a condition or disease.
No
The device description explicitly states the device is a physical abutment made of Ti-6A1-4V ELI, which is a hardware component. While it is designed using CAD/CAM software, the device itself is not software-only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for prosthetic rehabilitation on dental implants. This is a surgical and restorative procedure, not a diagnostic test performed on biological samples in vitro.
- Device Description: The device is a patient-specific abutment made of titanium, designed to connect a dental implant to a dental prosthesis. This is a medical device used in vivo (within the body).
- Lack of IVD Characteristics: There is no mention of analyzing biological samples (blood, urine, tissue, etc.), detecting specific analytes, or providing diagnostic information about a patient's health status.
IVD devices are specifically designed to perform tests on samples taken from the human body to provide information for diagnosis, monitoring, or screening. This device does not fit that description.

- Indications for use, abutment design, restoration, implant interface and abutment material, and the sterilization method.
- Differences
The subject device does not include an octa abutment interface and has a different pre-milled abutment body sizes, implant platform size, and maximum abutnent angle. Despite these compatible with the subject device, as well as the limitations on patient-specific abutments, including the maximum angle, fall within the range of those for the predicate device.
- Discussion
The subject device and primary predical ititanium abutments with precision implant/abutnent interface for use in fabricaing a patientspecific abutment at a manufacturer-validated milling center.
The subject device and predicate device indications for use, Abutment design, Restoration, Abutment/mplant interface, and Abutment material. These similarities effectively demonstrate the substantial equivalence between the two devices.
For the abutment angle of subject devices, the worst case was selected for XPEED AnyRidge Internal Inplant System starter test was performed to confirm the substantial equivalence with 'ISO 14801' and "Class II Special Controls Guidance Document. Root form Endosseous

Non-Clinical Testing
The subject device was tested to evaluate its substantial equivalence according to the following standards:
- . Fatigue Tests on the subject device were conducted under the worst-case scenario according to ISO 14801:2016
- Biocompatibility testing according to ISO 10993-1:2009
- . End User Sterilization Validation Test Report according to ANSI/AAMI ST79, ISO 17665-1, ISO 17665-2, ISO 11737-1, ISO 11737-2, and ISO 11138-1
- Reverse engineering analysis of OEM implant bodies, OEM abutments, and OEM abutment screws to confirm compatibility.
The results of the aforementioned tests have successfully met the criteria outlined in the standards, affirming the device's suitability for use.
Biocompatibility Testing was performed according to ISO 10993-1:2009, "Biological evaluation of medical devices – Part 1: Evaluation and testing within a risk management process," and to the FDA Guidance document, "Use of International Standard ISO 10993-1, 'Biological evaluation of medical devices- Part 1: Evaluation and testing within a risk management process', Guidance for Industry and Food and Drug Administration Staff", Document issued on: June 16, 2016", for subject abutments.
Non-clinical test data was conducted in accordance with FDA Guidance "Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Implant Abutments". This testing involved examining finished assembled implant/abutment systems of the worstcase scenario (smallest diameter with maximum angulation) through fatigue testing.
The recommended end user sterilization has been validated according to ISO 17665-2 and to applicable recommendations in the FDA guidance document "Reprocessing Medical Devices in Health Care Settings: Validation Methods and Labeling, issued on March 17, 2015" for subject abutments.
Dimensional analysis and reverse engineering of the implant-to-abutment connection platform were conducted, encompassing an assessment of maximum and minimum dimensions of critical design aspects, tolerances, and cross-sectional images of the submission device and compatible implant body, as well as the OEM implant abutment and implant body. The testing confirmed implant to abutment compatibility and established substantial equivalency of the proposed device with predicate devices.
MR Environment Condition
Non-clinical worst-case MRI review was performed to evaluate the metallic device 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
10
Labeling Medical Devices for Safety in the Magnetic Resonance (MR) Environment," including magnetically induced displacement force and torque.
The results of the above non-clinical tests have met the standards and demonstrated the substantial equivalence with the predicate device.
Clinical testing was deemed unnecessary to establish substantial equivalency of the device.
Conclusion
PreXolid CAD/CAM Abutments constitutes a substantially equivalent medical device, meeting all the declared requirements of its intended use. This system has similar intended use and fundamental scientific technology as its predicate devices. Therefore, PreXolid CAD/CAM Abutments and their predicates are substantially equivalent.
