The summary describes a digital dentistry workflow involving scanning, design software, and milling, but there is no mention of AI or ML being used in the design or manufacturing process. The design software mentioned (3Shape Abutment Designer Software) is a predicate device and its 510(k) summary would need to be reviewed to determine if it incorporates AI/ML. However, based solely on the provided text, there is no indication of AI/ML in the Elos Accurate® Customized Abutments themselves or their manufacturing process.
No
The device is a prosthetic component (an abutment) that provides a basis for dental restorations; it does not treat or cure a disease or condition.
No
This device is described as a "patient specific abutment intended for attaching to dental implants in order to provide basis for single- or multiple tooth prosthetic restorations." Its purpose is to physically support dental prosthetics, not to diagnose a condition or disease.
No
The device description clearly states the device is a physical abutment made of Titanium alloy, which is a hardware component. While it is manufactured according to a digital workflow, the final product is a physical medical device.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is to provide a basis for dental prosthetic restorations by attaching to dental implants. This is a mechanical and structural function within the body, not a diagnostic test performed on samples taken from the body.
- Device Description: The description details a physical abutment made of titanium alloy, designed to be attached to an implant and then to a crown. This is a medical device for implantation and restoration, not a diagnostic tool.
- Lack of Diagnostic Function: There is no mention of the device being used to diagnose a disease, condition, or state of health by examining samples like blood, urine, or tissue.
- Input Imaging Modality: While it uses scan files, these are used for designing the physical abutment, not for analyzing biological samples for diagnostic purposes.
- Performance Studies: The performance studies focus on mechanical properties (fatigue, dimensional analysis), biocompatibility, sterilization, and the digital workflow for manufacturing the physical device. There are no studies related to diagnostic accuracy (sensitivity, specificity, etc.).
In summary, the Elos Accurate® Customized Abutment is a dental prosthetic device, not an in vitro diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Non clinical testing data submitted (either in subject- or predicate submission) included:
- Engineering and dimensional analysis of original manufactures' components (abutments, implants & abutinent screws) for determination of compatibility. (The compatibility analysis is conducted on primary predicate device (K190299, K171799, K192457, K191890) and can be leveraged to the subject Elos Accurate Customized Abutments as material, size and geometry are substantial equivalent)
- Fatigue testing per ISO 14801 according to FDA guidance for Industry and FDA Staff "Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Abutments" dated May 12, 2004. The Fatigue test are conducted on the primary predicate device (K190299, K171799, K192457, K191890) and can be leveraged to the subject Elos Accurate Customized Abutments as material, size and geometry are substantial equivalent
- Biocompatibility testing for cytotoxicity according to ISO 10993-5. Tests included covered:
- non-coated prosthetic screw representative for subject device (test of primary predicate device K190299)
- Medicarb coated prosthetic screw representative for subject device (test of primary predicate device K171799)
- Elos Accurate® Customized Abutment representative for subject devices (test of primary predicate device (K171799))
- Sterilization validation according to ISO 17665-1 & ISO 17665-2, demonstrating a SAL of 10°. (The sterilization and Dry-time studies are conducted on the Primary Predicate Device (K171799) and can be leveraged to the subject Elos Accurate Customized Abutnents as material, size and geometry are substantial equivalent)
- The digital dentistry workflow validation was completed on selected model of subject product line with a digital dentistry workflow including a 3Shape scanner, 3Shape Abutment Designer Software (K155415) and CORiTEC Imes-Icore milling unit. The validation was provided for the subject abutment design library (not allowing the user to design outside the design limits set by Elos Medtech) to demonstrate use with the 3Shape Abutment Designer™ Software (K151455). The design library file (DME-file) provided by Elos Medtech includes design limits in accordance with Electronic Package insert -Instruction For Use, Surgical & Prosthetic Guide - In Lab Milling. The 3Shape Abutment Designer™ Software (K151455) prevents designing outside the specified design limits in the library file.
- Elos Medtech Pinol A/S solely manufactures abutments and screws in TiAl6V4 ELI. The screws are either uncoated or Medicarb coated. The Customized Abutments are delivered uncoated for machining by the dental lab. The screws and abutments are designed to be compatible with many different implant systems from implant manufacturers, which are made of titanium allovs, mostly titanium grade 4 (commercially pure Ti). TiAl6V4 ELI. commercially pure Ti and the used coating does not contain ferromagnetic materials (such as Fe, Co and Ni), meaning that the MRI response will be limited. To verify that a worstcase assembly made of Elos Medtech devices was MR conditional, a range of tests was performed on the worst-case assembly according to ASTM F2052, ASTM F2119, ASTM F2213 and ASTM F2182. The device has been assessed at 1.5 Tesla and 3 Tesla for displacement, torque, heating and image artifact in the MRI scanner, which proved that the proposed devices are MR conditional to use when having an MRI scan.
- To address the potential risk of damage to the implant-abutiment connection geometry during the milling of the patient-matched portions of the abutment blanks, validation testing of CAM restriction zones was conducted, including verification to show avoidance of damage or modification of the connection geometry, and locking of restriction zones from user editing in the CAM software.

IX. Summary of the Technological Characteristics:
The subject devices have similar Indications for Use, intended use, designs, sizes and configurations, materials, and principles of operation as the primary predicate device Elos Accurate® Customized Abutment Device (K190299, K171799, K192457, K191890). In order to determine nominal dimensions and tolerances of the Elos Accurate® Customized Abutment products, measuring- and dimensional analyses of original manufacturers' components (abutments, implants & abutment screws) have been made.
Comparing to the primary predicate device, the specific language (wording) of the Indications for Use Statements is identical except for the change in manufacturing from an FDA registered Elos Medtech approved milling facility to that the abutments should be designed and manufactured using a specific digital dentistry workflow.
The clamping of the Subject device during milling is changed to the opposite end than the connection interface which differ from Primary Predicate Device (K190299, K171799, K 192457, K 191890). This difference has no impact on the final customized abutunent design.

X. Discussion of the Non-Clinical Testing:
Non clinical testing data submitted (either in subject- or predicate submission) included:
11
- . Engineering and dimensional analysis of original manufactures' components (abutments, implants & abutinent screws) for determination of compatibility. (The compatibility analysis is conducted on primary predicate device (K190299, K171799, K192457, K191890) and can be leveraged to the subject Elos Accurate Customized Abutments as material, size and geometry are substantial equivalent)
- . Fatigue testing per ISO 14801 according to FDA guidance for Industry and FDA Staff "Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Abutments" dated May 12, 2004. The Fatigue test are conducted on the primary predicate device (K190299, K171799, K192457, K191890) and can be leveraged to the subject Elos Accurate Customized Abutments as material, size and geometry are substantial equivalent
- Biocompatibility testing for cytotoxicity according to ISO 10993-5. Tests included ● covered:
- non-coated prosthetic screw representative for subject device (test of primary .
- . predicate device K190299)
- Medicarb coated prosthetic screw representative for subject device (test of -
- primary predicate device K171799) -
- Elos Accurate® Customized Abutment representative for subject devices (test of . primary predicate device (K171799))
- . Sterilization validation according to ISO 17665-1 & ISO 17665-2, demonstrating a SAL of 10°. (The sterilization and Dry-time studies are conducted on the Primary Predicate Device (K171799) and can be leveraged to the subject Elos Accurate Customized Abutnents as material, size and geometry are substantial equivalent)
- . The digital dentistry workflow validation was completed on selected model of subject product line with a digital dentistry workflow including a 3Shape scanner, 3Shape Abutment Designer Software (K155415) and CORiTEC Imes-Icore milling unit. The validation was provided for the subject abutment design library (not allowing the user to design outside the design limits set by Elos Medtech) to demonstrate use with the 3Shape Abutment Designer™ Software (K151455). The design library file (DME-file) provided by Elos Medtech includes design limits in accordance with Electronic Package insert -Instruction For Use, Surgical & Prosthetic Guide - In Lab Milling. The 3Shape Abutment Designer™ Software (K151455) prevents designing outside the specified design limits in the library file.
- . Elos Medtech Pinol A/S solely manufactures abutments and screws in TiAl6V4 ELI. The screws are either uncoated or Medicarb coated. The Customized Abutments are delivered uncoated for machining by the dental lab. The screws and abutments are designed to be compatible with many different implant systems from implant manufacturers, which are made of titanium allovs, mostly titanium grade 4 (commercially pure Ti). TiAl6V4 ELI. commercially pure Ti and the used coating does not contain ferromagnetic materials (such as Fe, Co and Ni), meaning that the MRI response will be limited. To verify that a worstcase assembly made of Elos Medtech devices was MR conditional, a range of tests was performed on the worst-case assembly according to ASTM F2052, ASTM F2119, ASTM F2213 and ASTM F2182. The device has been assessed at 1.5 Tesla and 3 Tesla for displacement, torque, heating and image artifact in the MRI scanner, which proved that the proposed devices are MR conditional to use when having an MRI scan.
- . To address the potential risk of damage to the implant-abutiment connection geometry during the milling of the patient-matched portions of the abutment blanks, validation
12
testing of CAM restriction zones was conducted, including verification to show avoidance of damage or modification of the connection geometry, and locking of restriction zones from user editing in the CAM software.
XI. Conclusions:
Based on the test results and additional supporting documentation provided in this premarket notification, the subject devices demonstrated substantial equivalence to the previously listed predicate devices.
