Intended Use

The Neodent Implant System is intended to be surgically placed in the bone of the upper or lower jaw to provide support for prosthetic devices, such as artificial teeth, to restore chewing function. It may be used with single-stage or two-stage surgical procedures, for single or multiple unit restorations, and may be loaded immediately when good primary stability is achieved and with physiological occlusal loading. Multiple teeth applications can be rigidly splinted. Healing,

The Zirconia Base is an abutment placed over Neodent Zirconia Implants in order to provide support for custom-made prosthetic restorations, such as copings or crowns. It may be used for cement- or screw-retained single unit restorations. All digitally designed copings and/or crowns to be used with the Neodent Zirconia Base Abutment System are intended to be sent to Straumann for manufacture at a validated milling center.

The CR Abutment is an abutment placed over Neodent Zirconia Implants in order to provide support for prosthetic restorations, such as copings or crowns. It may be used for single unit restorations that are cement-retained in esthetical areas over implants installed in maxilla or mandible.

The PEEK CR Abutment is indicated to be used on Neodent Implants to provide support for prosthetic structures for up to 6 months. They can be used in single- or two-stage procedures and they are intended to be placed out of occlusion.

Device Description

The Zirconia Abutments subject of this submission are similar to devices already approved in previous submissions of Zirconia Implant System, according to predicate devices described above. This submission intends to expand the portfolio of Zirconia Abutments with new dimensions of gingival height for Zirconia Healing Abutments, Zirconia Bases, CR Abutments for Zirconia and PEEK CR Abutments for Zirconia, to provide more treatment options to the customers. All these abutments have an internal connection with the implants (ZiLock) and the prosthetic platform is identical for all subject devices described in this submission. They are intended for single use and provided sterile via Ethylene Oxide method. The new transmucosal heights are 3.5mm and 4.5mm.

The restorative materials Polycon ae, N!ce and IPS e.max CAD LT were not presented in previous submissions of Zirconia Implant System and are being included in the scope of Zirconia Bases indication.

AI/ML Overview

The provided document is a 510(k) summary for the Neodent Implant System - Zirconia Implant System. This type of FDA submission focuses on demonstrating substantial equivalence to a legally marketed predicate device, rather than proving a device meets specific acceptance criteria through a clinical study with defined performance metrics, sample sizes, and expert adjudication as might be seen for novel AI/software as a medical device (SaMD) products.

Therefore, the document does not contain the information requested regarding acceptance criteria related to a study proving performance, sample sizes for test sets, data provenance, number or qualifications of experts for ground truth, adjudication methods, MRMC studies, standalone algorithm performance, or ground truth establishment methods for training sets.

The performance testing section (pages 14-15) describes:

  • Bench Testing:
    • Dynamic fatigue testing: Conducted according to FDA guidance and ISO 14801. The results demonstrated the subject devices do not introduce a new worst case compared to predicate and reference devices.
    • Torsion tests: Performed to evaluate screw strength, and results proved adequate torsion strength according to installation torque.
  • Biocompatibility Testing:
    • Assessment performed according to ISO 10993-1 and FDA guidance. No new issues were raised and no additional testing was required because the subject devices are identical in material and manufacturing processes to predicate and reference devices.
  • Sterilization Validation and Packaging:
    • Ethylene Oxide (EO) sterilization validated to SAL of 10-6 per ISO 11135:2014. EO residuals verified per ISO 10993-7. The packaging and sterilization are identical to predicate devices.
    • Steam sterilization validated per ISO 17665-1, using parameters identical to predicate devices.
    • Pyrogen limit specifications met via LAL Endotoxin Analysis (testing limit 20 EU/device) for blood contacting and implanted devices.

In essence, the study presented is a non-inferiority or equivalence-based assessment against previously cleared devices, focusing on engineering and biocompatibility characteristics, not clinical performance metrics or AI algorithm validation metrics.

Therefore, I cannot provide the requested table and details because the information is not present in the provided text. The document describes a traditional medical device (dental implants and abutments) clearance, not a software or AI device that would have the specific performance study criteria outlined in your request.

Performance Testing

Bench Testing

Assessment regarding dynamic fatigue testing was conducted according to the FDA guidance document "Guidance for Industry and FDA Staff – Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Abutments" and ISO 14801 "Dentistry - Implants - Dynamic loading test for endosseous dental implants". The results demonstrated the subject devices do not introduce a new worst case compared to the primary predicate and reference devices. In addition to testing on subject device, dynamic fatigue testing was leveraged from the primary predicate (K201491).

Torsion tests were performed to evaluate the strength of the screw supplied with all subject abutments against maximum twisting forces. The results proven that there is an adequate torsion strength according to the installation torque indicated in IFU.

Biocompatibility Testing

A biological assessment was performed according to ISO 10993-1 "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 each subject device.

The subject devices are identical in material and manufacturing processes to the primary predicate and reference devices, therefore, no new issues regarding biocompatibility were raised and no additional biocompatibility testing was required.

Sterilization Validation and Packaging

The subject devices are provided sterile via Ethylene Oxide (EO) method, validated to a sterility assurance level (SAL) of 106 in accordance with ISO 11135:2014, "Ethylene Oxide – Part 1: Requirements for development, validation and routine control of a sterilization process for medical devices". EO sterilization residuals have been verified to be less than the maximum allowable limits as defined in ISO 10993-7 "Biological Evaluation of Medical Devices - Part 7: Ethylene Oxide Sterilization Residuals". The packaging and sterilization of the subject device are identical to the packaging and sterilization of the primary predicate devices.
