Device Description

The Osteon Precision Milled Suprastructures (also referred to as superstructures) are metallic dental restorative devices that are intended to be attached by screw retention to dental implant abutments to aid in the treatment of partial and totally edentulous patients for the purpose of restoring chewing function. These suprastructures attach to dental implant abutments using the prosthetic screws from the original equipment manufacturers (OEM) and are used to support the final multi-unit restoration.

The Osteon Precision Milled Suprastructure is designed for an individual patient from scans of the patient's dental impression. The suprastructure is manufactured with the aid of Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM) technology. All CAD/CAM fabrication is performed by Osteon Medical.

Osteon Precision Milled Suprastructures facilitate the attachment of both removable and fixed dental prosthesis and hence are categorized as Type A and Type B.

  • Type A: Intended to act as a supporting structure to facilitate the attachment of a removable dental prosthesis and include Primary Bar and Nexus Removable Bar.
  • . Type B: Intended to act as a supporting structure to facilitate the attachment of a fixed dental prosthesis and include Melbourne Bar and Nexus Fixed Bar (including Nexus Hybrid, Nexus Bridge, Micro Nexus, and Nexus Wraparound).
AI/ML Overview

The provided FDA 510(k) summary (K233083) describes the acceptance criteria and study for the Osteon Precision Milled Suprastructure.

1. Table of Acceptance Criteria and Reported Device Performance

This submission is a 510(k) for an expansion of an existing device (K221019) to add compatibility with new OEM abutment systems and introduce three new Type B Nexus Fixed Bars. The acceptance criteria are primarily based on demonstrating substantial equivalence to the predicate devices in terms of intended use, technological characteristics, and material composition.

The tables below synthesize the design specifications (acceptance criteria) and the device's performance (reported as meeting these specifications) by demonstrating substantial equivalence to predicate devices.

2. Sample size used for the test set and the data provenance

The submission is a 510(k) for an expansion of an existing device (K221019). The "study" proving the device meets acceptance criteria primarily relies on non-clinical data and demonstration of substantial equivalence to predicate devices.

  • Test set/Sample size: The document does not describe a "test set" in the traditional sense of a clinical or imaging study with a defined sample size for statistical analysis. Instead, it relies on:
    • Reverse engineering analysis of OEM abutments and OEM abutment screws: This was done to confirm compatibility. The sample size for this analysis is not explicitly stated but would involve the specific OEM abutments listed for compatibility with the subject device.
    • Fatigue testing: The document states, "Fatigue testing was not performed since the Subject devices are abutment-borne and are not intended to compensate for angulation in excess of the maximum angulation of OEM angled abutments..." This indicates that engineering analysis and design specifications, rather than physical fatigue testing, were used to demonstrate performance in this regard.
  • Data provenance: Not directly applicable as there isn't a "test set" from patients. The data relies on engineering analysis, existing predicate device data, and compliance with standards.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

Not applicable. This is not a study requiring expert readers to establish ground truth. Substantial equivalence claims are based on engineering, material, and design comparisons to legally marketed devices.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set

Not applicable. There is no "test set" or diagnostic performance study that would require an adjudication method.

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 physical dental suprastructure, not an AI-powered diagnostic tool.

6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done

Not applicable. This device is a physical dental suprastructure, not an algorithm.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

The "ground truth" equivalent for this submission is the established safety and effectiveness of the primary predicate device (K221019) and various reference devices, supported by:

  • Compliance with recognized standards: Biocompatibility (ISO 10993-5, ISO 10993-12), sterilization validation (ANSI/AAMI/ISO 17665-1, ANSI/AAMI/ISO 17665-2, ANSI/AAMI/ISO 14937).
  • Material specifications: Conformance to ASTM F136 for titanium alloy.
  • Engineering analysis and design specifications: Comparison of design features to predicate devices and confirmation of compatibility through reverse engineering.

8. The sample size for the training set

Not applicable. This is not a machine learning or AI device that requires a training set.

9. How the ground truth for the training set was established

Not applicable. As above, there is no training set for this device.

SUBJECT DEVICE DESCRIPTION

The purpose of this submission is to expand the Osteon Precision Milled Suprastructure cleared under K221019, K2121019, K221381 and K223814 to add additional OEM compatibility to BioHorizons Abutments, Biomet 3i Abutments, MegaGen Abutments, OSSTEM Abutments, and Medentika Abutments. Three (3) additional Type B Nexus Fixed Bars have been designed to accommodate additional fixed dental prosthesis types (Nexus Bridge, Micro Nexus Wraparound). The Micro Nexus Bar can be utilized when up to half of the arch is considered for a restoration, while the Nexus Hybrid, Nexus Bridge, and Nexus Wraparound are utilized for full arched fixed restorations and selection of the bar type is made based on aesthetic requirements of the patient.

The Osteon Precision Milled Suprastructures (also referred to as superstructures) are metallic dental restorative devices that are intended to be attached by screw retention to dental implant abutments to aid in the treatment of partial and totally edentulous patients for the purpose of restoring chewing function. These suprastructures attach to dental implant abutments using the prosthetic screws from the original equipment manufacturers (OEM) and are used to support the final multi-unit restoration.

The Osteon Precision Milled Suprastructure is designed for an individual patient from scans of the patient's dental impression. The suprastructure is manufactured with the aid of Computer Aided Design (CAD) and Computer Aided Manufacturing (CAM) technology. All CAD/CAM fabrication is performed by Osteon Medical.

Osteon Precision Milled Suprastructures facilitate the attachment of both removable and fixed dental prosthesis and hence are categorized as Type A and Type B.

  • Type A: Intended to act as a supporting structure to facilitate the attachment of a removable dental prosthesis and include Primary Bar and Nexus Removable Bar.
  • . Type B: Intended to act as a supporting structure to facilitate the attachment of a fixed dental prosthesis and include Melbourne Bar and Nexus Fixed Bar (including Nexus Hybrid, Nexus Bridge, Micro Nexus, and Nexus Wraparound).

MATERIAL COMPOSITION

The Osteon Precision Milled Suprastructure is manufactured from titanium alloy conforming to the requirements of ASTM F136 Standard Specification for Wrought Titanium-6 Vanadium ELI (Extra Low Interstitial) Alloy for Surgical Implant Applications (UNS R56401). This material to that of the primary predicate device K221019.

PERFORMANCE DATA

Non-clinical data submitted to demonstrate substantial equivalence included: biocompatibility according to ISO 10993-5 and ISO 10993-12 leveraged from K212676; sterilization validation according to ANSI/AAMI/ISO 17665-1, ANSI/AAMI/ISO 17665-2 and ANSI/AAMI/ISO 14937 and reverse engineering analysis of OEM abutments and OEM abutment screws to confirm compatibility. No clinical data were included in this submission.

EQUIVALENCE TO MARKETED DEVICE

The Subject device is substantially equivalent in indications and design principles to the primary predicate device listed above. Provided at the end of this summary is a table comparing the Indications for Use Statements and the technological characteristics of the Subject device and the Primary Predicate device K221019 and Reference devices K212676, K221381 and K223814.

The Subject device is substantially equivalent in intended use to the Primary Predicate device cleared in K221019 and Reference Devices K212676, K221381 and K223814. The Indications for Use Statement (IFUS) for the Subject device is substantially equivalent to that of the Primary Predicate K221019, except for the list of compatible OEM implants.

The Subject device is identical in design, materials, and technological characteristics to the corresponding Primary Predicate device K221019 and Reference devices K212676, K221381 and K223814. There have been no changes to the previously cleared bars, and they remain the same as the Primary Predicate K221019. New bar cylinders (mating components) have been designed to accommodate the new compatible abutments that, other than the compatibilities, are identical to the bar cylinders that were cleared in the Primary Predicate K221019. Three additional Type B Fixed Prosthesis Bars are within this submission, including the Nexus Bridge, Micro Nexus, and Nexus Wraparound. These bars are similar in design to the Primary Predicate K221019, with the use of the bar cylinders to create the custom bar design for a specific patient. Fatigue testing was not performed since the Subject devices are abutment-borne and are not intended to compensate for angulation in excess of the maximum angulation of OEM angled abutments in each Reference device clearance, as outlined in the Indications for Use Statement.

The Subject device is to be sterilized by the end-user, highly similar to primary predicate device K221019 and Reference devices K212676, K221381 and K223814.

The Subject device is to be manufactured from the same materials and in the same facilities using the same manufacturing processes as used for the Osteon Precision Milled Suprastructure previously cleared in K221019. Therefore, no new biocompatibility testing has been performed, as the Subject device is substantially equivalent to the predicate devices in K221019 and the Reference devices in K212676, K221381 and K223814 with regard to materials and processing.

{10}------------------------------------------------

CONCLUSION

The Subject device and the primary predicate device have the same intended use, have similar technological characteristics, and are made of the same materials. The Subject device and the primary predicate encompass the same range of physical dimensions, are packaged in same materials, and are to be sterilized using highly similar methods. The data included in this submission demonstrate substantial equivalence to the predicate devices listed above.
