Duranext Abutments are intended for use with dental implants as a support for single or multiple toth prostheses in the maxilla or mandible of a partially or fully edentulous patient.
Duranext Abutments from Elegant Direct Corp. are a line of machinable blanks incorporating interface features compatible with eleven (11) endosseous dental implant system platforms (three (3) designs from two (2) manufacturers) and intended to be milled at an Elegant Direct Corp. validated milling center to produce patient-specific dental implant abutments. The subject device platform diameters range from 3.0 mm to 6.0 mm, and the corresponding compatible implant body diameters range from 3.0 mm to 6.0 mm.
Duranext Abutments are designed for fabrication of custom titanium alloy dental implant abutments by a CAD/CAM process. All patient-specific custom abutment fabrication is by prescription on the order of the clinician. The portion of each abutment available for milling is 9.5 mm in diameter and 20 mm long. The apical end is premanufactured to fit the compatible implant platform, as shown above, and is available in an engaging (anti-rotation) design. A feature at the coronal end of the abutment is provided to interface with the milling equipment. Each abutment is provided with a screw designed to fit the compatible implant. The patient-specific abutment is intended to support a cement-retained single crown or multi-unit restoration.
The provided document is a 510(k) summary for the Duranext Abutments, a dental device. It does not describe a study involving an AI algorithm or human-in-the-loop performance. Therefore, I cannot extract the information required for questions about AI performance, multi-reader multi-case studies, or specific details of ground truth establishment for AI training/testing.
However, I can provide information about the acceptance criteria and the non-clinical study that proves the device meets those criteria, as well as general device information.
Here's what can be extracted based on the document:
1. A table of acceptance criteria and the reported device performance
The document does not explicitly present a table of "acceptance criteria" in the format of a diagnostic test (e.g., sensitivity, specificity). Instead, substantial equivalence is claimed based on performance testing and comparison to predicate devices for mechanical properties, biocompatibility, and sterilization. The acceptance criteria are implicitly met by successful completion of these tests in accordance with relevant ISO standards.
| Acceptance Criterion (implicitly met by standard) | Reported Device Performance (Summary) |
|---|---|
| Sterilization | Sterilization according to ISO 17665-1 (demonstrated readiness for sterilization) |
| Biocompatibility | Biocompatibility according to ISO 10993-12 (for general requirements), and specifically ISO 10993-5 (cytotoxicity) |
| Compatibility with OEM Implants | Reverse engineering of OEM implant bodies, OEM abutments, and OEM abutment screws (confirmed compatibility) |
| Mechanical Strength / Dynamic Fatigue | Static compression and compression fatigue testing according to ISO 14801 (sufficient strength for intended use) |
| Design Parameters (for CAD/CAM abutments) | Minimum wall thickness: 0.5 mm |
| Minimum post height: 4.0 mm | |
| Maximum abutment height from prosthetic platform: 20.0 mm | |
| Maximum gingival height: 4.0 mm | |
| Minimum gingival height: 0.5 mm | |
| Angulation: 0° to 30° |
2. Sample size used for the test set and the data provenance (e.g., country of origin of the data, retrospective or prospective)
The document does not mention "test sets" in the context of diagnostic data. The "testing" refers to non-clinical performance testing of the physical abutment blanks. The sample sizes for these specific engineering tests (e.g., number of abutments tested for fatigue) are not provided in this summary. The provenance is implied to be from the manufacturer's testing or a contracted lab.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts (e.g., radiologist with 10 years of experience)
Not applicable, as this is a physical medical device (dental abutment) and the evaluation is based on non-clinical performance testing against engineering standards, not diagnostic interpretation by experts.
4. Adjudication method (e.g., 2+1, 3+1, none) for the test set
Not applicable. Adjudication methods like 2+1 or 3+1 are used for establishing ground truth in diagnostic studies, which is not what this document describes.
5. If a multi reader multi case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
Not applicable. This device is a dental abutment, not an AI-powered diagnostic tool. No MRMC study was conducted.
6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done
Not applicable. This device is not an algorithm.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
The "ground truth" for this device's performance is established by engineering standards and physical measurements. For example:
- Biocompatibility: Established by adherence to ISO 10993 series standards, which involves methods like cytotoxicity testing.
- Mechanical Strength: Established by dynamic fatigue testing according to ISO 14801, which defines acceptable load cycles and failure modes.
- Dimensional Compatibility: Established by reverse engineering and direct measurement against OEM specifications.
8. The sample size for the training set
Not applicable. This device is not an AI algorithm, so there is no training set in the context of machine learning.
9. How the ground truth for the training set was established
Not applicable. As above, there is no training set. The "ground truth" for the device's design and manufacturing parameters is established via engineering specifications, material properties, and adherence to relevant ISO standards, rather than a labeled dataset.

SUBJECT DEVICE DESCRIPTION
Duranext Abutments from Elegant Direct Corp. are a line of machinable blanks incorporating interface features compatible with eleven (11) endosseous dental implant system platforms (three (3) designs from two (2) manufacturers) and intended to be milled at an Elegant Direct Corp. validated milling center to produce patientspecific dental implant abutments. The subject device platform diameters range from 3.0 mm to 6.0 mm, and the corresponding compatible implant body diameters range from 3.0 mm to 6.0 mm.
{5}------------------------------------------------
Duranext Abutments are designed for fabrication of custom titanium alloy dental implant abutments by a CAD/CAM process. All patient-specific custom abutment fabrication is by prescription on the order of the clinician. The portion of each abutment available for milling is 9.5 mm in diameter and 20 mm long. The apical end is premanufactured to fit the compatible implant platform, as shown above, and is available in an engaging (anti-rotation) design. A feature at the coronal end of the abutment is provided to interface with the milling equipment. Each abutment is provided with a screw designed to fit the compatible implant. The patient-specific abutment is intended to support a cement-retained single crown or multi-unit restoration.
The design parameters for the CAD/CAM fabrication of custom abutments from Duranext Abutment are:
Minimum wall thickness - 0.5 mm Minimum post height - 4.0 mm Maximum abutment height from the prosthetic platform - 20.0 mm Maximum gingival height - 4.0 mm Minimum gingival height - 0.5 mm Angulation - 0° to 30°
Manufacture of CAD/CAM custom abutments from Duranext Abutments is to be performed at an Elegant Direct Corp. validated milling center that is registered with FDA as a medical device manufacturing establishment.
PERFORMANCE DATA
Non-clinical data submitted to demonstrate substantial equivalence included: sterilization according to ISO 17665-1; biocompatibility according to ISO 10993-12; reverse engineering of OEM implant bodies, OEM abutments, and OEM abutment screws to confirm compatibility; and static compression and compression fatigue testing according to ISO 14801. No clinical data were included in this submission.
EQUIVALENCE TO MARKETED DEVICES
The subject device is substantially equivalent in indications and design principles to the primary predicate device and the reference devices listed above. Provided at the end of this summary are tables comparing the Indications for Use Statements and the technological characteristics of the subject device, the primary predicate device, and the reference devices.
With regard to intended use, the subject Duranext Abutment is substantially equivalent to the primary predicate device, K 150203 Medentika CAD/CAM Abutments and to the abutment reference devices K160784 CAM Titanium Blanks, K171799 Elos Accurate Customized Abutment and K134045 Zimmer Zfx Ti Abutment for NobelReplace CC. All are intended for use with dental implants as a support for single tooth prostheses in the maxilla or mandible of a partially or fully edentulous patient. While the primary predicate device is intended for use with the Straumann CARES System, digitally designed abutments for use with the abutment reference devices are intended to be sent to a validated milling center for manufacture, as is the case for the subject device. With regard to OEM implant system compatibility, all subject device compatibilities are included in those for the primary predicate device, with the exception of the WP (5.5) platform of the NobelParallel Conical Connection implants. Slight differences in the wording of the Indications for Use do not affect the intended use of the device to support a single-tooth or multiple-unit prosthesis for restoration of chewing function.
With regard to design, the subject device, the primary predicate device and abutment reference devices all are titanium alloy blanks intended to be used for the manufacture of patient-specific abutments using CAD/CAM techniques, with manufacture of the final finished device performed at a validated milling center - an Establishment that is registered with FDA as a manufacturer. The design parameters intended for the subject device are substantially equivalent to those of the primary predicate device; maximum angulation for each is 30°, maximum abutment height is 20 mm and minimum post height is 4 mm, maximum gingival height for the subject
{6}------------------------------------------------
510(k) Summary Page 4 of 7
device is 4 mm, which is not a worse case than the 6 mm maximum gingival height of the primary predicate device.
Testing to support substantial equivalence included biocompatibility testing according to ISO 10993-5 and ISO 10993-12. In addition, performance testing according to ISO 14801 Dentistry - Implants - Dynamic fatigue test for endosseous dental implants was performed to demonstrate that the subject device has sufficient strength for its intended use when tested in dynamic loading.
CONCLUSION
The subject device, the primary predicate device, and the abutment reference devices have intended use, have similar technological characteristics, and are materials. The subject device, the primary predicate, and reference devices encompass the same range of physical dimensions, are packaged in similar materials, and are to be sterilized using similar methods. The data included in this submission demonstrate substantial equivalence to the predicate devices listed above.
