Intended Use

The CORE 3D abutment system for digital prosthetic solutions are dental abutments placed into a dental implant to provide support for dental prosthetic restorations. The abutments include: - Titanium Bases to be attached to the underlying implant and upon which a CAD/CAM designed superstructure may be fitted to complete a two-piece dental abutment; - Titanium Abutment Blanks with a pre-machined implant connection where the upper portion may be custom-milled in accordance with a patient-specific design using CAD/CAM techniques; - Abutment Screws to permanently fix the abutments to the underlying implant. Core 3D abutments are intended for use to support single-tooth (unit) and multiple-tooth (bridges and bars) prostheses, in the mandible or maxilla for functional and aesthetic restorations. Core 3D abutments designed using CAD/CAM techniques must fulfill the Core 3D allowable range of design specifications and be provided as straight abutments only. Core 3D abutments and are compatible for use with the following dental implants: - Nobel Biocare® Brånemark System™ (K022562, K934825) . - Zimmer® Tapered Screwvent® (K013227, K061410, K072589) Abutments are placed into the dental implant to provide support for the prosthetic reconstruction including abutments for cemented restorations to achieve better esthetics. Abutments can be used to restore crowns for single tooth replacements and bridges for multiple tooth restorations.

# DEVICE DESCRIPTION:

The proposed devices are dental implant abutments intended to be placed into dental implants and to provide support for dental prosthetic restorations.

The system is composed of the following principal components:

- Titanium Bases to be attached to the underlying implant and upon which a CAD/CAM designed superstructure may be fitted to complete a two-piece dental abutment;
- Titanium Abutment Blanks with a pre-machined implant connection where the upper portion may be custom-milled in accordance with a patient-specific design using CAD/CAM techniques
- -Abutment Screws: to fix abutments to the underlying dental implant.

The final form of the device including superstructures to titanium bases and patientspecific designs for abutment blanks may be designed using CAD CAM techniques under Core3D design specifications and limitations using the following system:

- CAD/CAM Software: 3Shape Dental System including 3Shape Dental Designer ー
- Scanner: 3Shape D810 model -
- -Milling machine: SAUER HSC-20 DMG.

Mechanical resistance of the implant-abutment connection is essential to ensure correct long-term . functional performance of the complete dental restoration. Dimensional compatibility and mechanical performance of bases and screws together with the underlying implant are of primary importance. These concepts are the basis upon which the system design characteristics and functional

# Section 5 - 510(k) Summary

## SUMMARY DISCUSSION OF NON-CLINICAL DATA:

The proposed device has been subject to bench testing to determine conformance to performance specifications and requirements taking account of its intended use as an endosseous dental implant abutment and following all indications set out in FDA Document "Guidance for Industry and FDA Staff - Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Implant Abutments".

Bench testing performed in foreseeable operating conditions included determination of the compatibility of the abutment - implant mating characteristics as well as mechanical compression and fatigue testing - all testing showed correct operation of the device as per its intended use, specifically including dimensional compatibility and mechanical performance testing.

Also, testing included software validation testing of the software system used to ensure that incorporated design limitations correctly prevent the user from milling abutments that do not fulfill the Core3D design criteria.

### SUMMARY DISCUSSION OF CLINICAL DATA:

Non-clinical test data are submitted to support this premarket notification and to establish the decision concerning adequate safety and performance of the predicate device. Clinical data are not submitted.

### CONCLUSIONS:

We believe the intended use, the indications for use and performance of the Core3D abutment system for digital prosthetic solutions are the intended use, indications for use and performance of the predicate devices. We also believe that the Core3D devices do not suppose any new or increased risk compared with the predicate devices. Based on the information included in this submission, we conclude that the proposed device is substantially equivalent to the legally marketed predicate devices.
