NizPlant Implants are a one-piece implant or two-piece assembly for single-stage surgical procedures intended for surgical implantation in edentulous or partially edentulous mandibles or maxilla for attachment of complete denture prostheses, or for fixed or removable bridgework for multi-unit tooth replacement.

NizPlant Implants can be indicated for immediate function when initial implant stability has been achieved and with appropriate occlusal loading.

Short (<9mmL) Implants: Indicated for multiple-unit restorations of partially or fully edentulous mandibles and maxillae where vertical bone volume is limited.

The NizPlant Implants have a 2.5mmD internal hex within its most coronal portion for the insertion tool placement used in the full seating of the NizPlant Implant in the osteotomy. Implant placement, which is designed to receive multiple abutment variations, expands its restorative options allowing for the implant to be used for:
• Support of attachment-retained overdentures
• Support of screw-retained prostheses

The NizPlant Dental Implant System consists of a root form Endosseous dental implant and various other prosthetic/restorative components (medical devices) to plan, implant, and support restorations for edentulous patients.

NizPlant Implants are a one-piece implant or two-piece assembly for single-stage surgical procedures intended for surgical implantation in edentulous or partially edentulous mandibles or maxilla for attachment of complete denture prostheses, or for fixed or removable bridgework multi-unit tooth replacement.

The top one-third of the NizPlant Implant body has a straight machined neck that is placed in crestal bone. The depth gauge lines at 1mm, 2mm and 2.5mm from the top of the straight machined neck portion of the implant body facilitate the placement level with the crest of the ridge or 1mm above the crest of the ridge. Above the straight neck of the implant body is a dual-function platform which acts as an overdenture or a multi-unit abutment.

The lower two-thirds of the Implant is tapered with double-lead progressively deeper reverse buttress threads for increased bone contact. The two full-length cutting grooves are self-tapping and extend over the tapered portion of the implant's body.

The NizPlant dental implant body is available in six diameter sizes. This assortment of implants in various diameters and lengths are to be matched with an extensive componentry offering. NizPlant Implants lengths are measured from the apex of the implant to the midpoint of the gold anodized zone, that is to the base of the abutment portion of the NizPlant Implant.

NizPlant Implants have a portion of their coronal surface anodized a gold color. The gold color aids aesthetically as it is the portion that extends transmucosal from bone level, through to the oral cavity by masking of the underlying color of the non-anodized standard titanium grey. Due to its length, the 7mmL and 9mmL implants have one less circumferential groove and are replaced with an additional external thread to increase fixation within the bone.

NizPlant Implants are specifically designed with a combination of 0.5mm and/or the 1mm height circumferential grooves above the blasted implant surface (7mmL - 9mmL implant does not have the additional 0.5mm circumferential score line). These visual demarcations aid the clinician by providing the option for vertical height variability during placement. For restorations where the vertical position of the surrounding bone and/or soft tissue dictate that, part of the implant's anodized portion within the straight machined neck of the NizPlant Implant body may remain supra-crestal after placement (in addition to the 3mm prosthetic option of the dual function platform).

The NizPlant Implants are anodized a gold color with a portion of the Implant going through a surface treatment (blasting) to create a microtextured surface roughness. These implants (and the devices included in the packaging) are sold sterile. The NizPlant Implants are manufactured from titanium alloy (Ti-6Al-4V ELI) complying with standard ASTM F136-13 - Standard Specification for Wrought Titanium-6Aluminum-4Vanadium ELI (Extra Low Interstitial) Alloy for Surgical Implant.

The various devices included in the NizPlant Implant System (such as Endosseous dental implant abutments, cover screws, fixation screw, etc.) and various other prosthetic/restorative components used to plan, implant, and support restorations for fully and partially edentulous patients are offered in compatible platform dimensions to enable a complete dental restoration.

The Cover Screws are available in 5.5mm diameter with a platform diameter of 3.5mm. They are manufactured from titanium alloy (Ti-6Al-4V ELI) complying with standard ASTM F136-13 - Standard Specification for Wrought Titanium-6Aluminum-4Vanadium ELI (Extra Low Interstitial) Alloy for Surgical Implant).

The provided FDA 510(k) clearance letter for URIS Long Implant & Abutments does not contain information about acceptance criteria and study proving device performance as typically expected for AI/ML-driven medical devices. This submission is for a traditional dental implant system, and the clearance is based on substantial equivalence to predicate devices through non-clinical testing, primarily focusing on mechanical, material, and biocompatibility properties.

Therefore, many of the requested elements regarding acceptance criteria for device performance (e.g., sensitivity, specificity, AUC), study design (sample size, data provenance, ground truth establishment, expert adjudication), and AI/ML-specific study types (MRMC, standalone performance) are not applicable to this submission.

However, I can extract the information relevant to the type of device and submission, specifically the non-clinical acceptance criteria and the tests performed to meet them.

Acceptance Criteria and Supporting Study for URIS Long Implant & Abutments

As this FDA 510(k) pertains to a traditional dental implant and abutment system (URIS Long Implant & Abutments, K243255), and not an AI/ML device, the acceptance criteria and study details are focused on non-clinical performance, primarily demonstrating mechanical integrity, material compatibility, and safety through established engineering and biological standards, rather than diagnostic accuracy metrics.

The clearance is largely based on demonstrating substantial equivalence to previously cleared predicate devices through a series of non-clinical tests.

1. Table of Acceptance Criteria and Reported Device Performance

Given the nature of this device (dental implants), the "performance" is demonstrated through engineering and biocompatibility testing rather than diagnostic accuracy. The acceptance criteria are implicitly meeting the requirements of the cited ISO and USP standards. The document doesn't provide specific quantitative "pass/fail" values for each test, but rather states that the device "met the criteria of the standards."

2. Sample Size Used for the Test Set and Data Provenance

• Sample Size: Not explicitly stated in terms of a "test set" as one would expect for an AI/ML device. The "sample size" would refer to the number of physical dental implants/abutments subjected to each non-clinical test (e.g., number of units for fatigue testing, number of samples for biocompatibility). These numbers are not detailed in the summary but would be standard for regulatory testing required by the ISO/ASTM standards cited (e.g., minimum of 5-10 samples for fatigue per condition).
• Data Provenance: Not applicable in the context of patient data for diagnostic accuracy. The "data" originated from laboratory testing of the manufactured dental implants and abutments.

3. Number of Experts Used to Establish Ground Truth for the Test Set and Qualifications

• Not Applicable: This clearance is based on non-clinical engineering and biological safety tests (e.g., fatigue strength, sterility, biocompatibility), not on the interpretation of medical images or patient data requiring expert consensus or ground truth establishment by clinical experts like radiologists.

4. Adjudication Method for the Test Set

• Not Applicable: As there is no human interpretation of data for diagnostic purposes, there's no need for an adjudication process. Test results are objective measurements (e.g., force at failure, sterility present/absent).

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study

• Not Performed / Not Applicable: MRMC studies are specific to evaluating diagnostic devices, particularly those involving human readers and AI assistance. This device is a physical dental implant, not a diagnostic AI tool.

6. Standalone (Algorithm Only) Performance Study

• Not Performed / Not Applicable: This is a physical medical device, not a software algorithm.

7. Type of Ground Truth Used

• Engineering/Material Standards and Biological Safety Standards: The "ground truth" for this device's performance is established by the specified ISO and ASTM standards (e.g., ISO 14801 for fatigue testing, ISO 10993-1 for biocompatibility). These standards define acceptable performance limits for mechanical properties and biological responses.

8. Sample Size for the Training Set

• Not Applicable: This device is not an AI/ML algorithm that requires a training set. Its design and manufacturing are based on established engineering principles and materials science.

9. How the Ground Truth for the Training Set Was Established

• Not Applicable: As there is no training set for an AI/ML algorithm, this question is not relevant.

This document describes a 510(k) premarket notification for the ZENEX Implant System Long, an endosseous dental implant. This type of submission relies on demonstrating substantial equivalence to a legally marketed predicate device, rather than proving safety and effectiveness through extensive clinical trials. Therefore, the information provided focuses on non-clinical testing and comparisons to predicate devices, rather than a study proving the device meets acceptance criteria in a clinical setting.

Here's an analysis of the provided information based on your requested points:

1. Table of Acceptance Criteria and Reported Device Performance

Since this is a 510(k) submission for substantial equivalence based primarily on non-clinical testing, there isn't a direct "acceptance criterion" table in the sense of clinical performance metrics (e.g., sensitivity, specificity). Instead, the "acceptance criteria" are the successful completion of various non-clinical tests according to established standards, demonstrating that the new device is as safe and effective as the predicate devices.

2. Sample Size Used for the Test Set and the Data Provenance

• Sample Size for Test Set: Not explicitly stated as a single "test set" in the context of a clinical study. For non-clinical tests:
  • Fatigue Testing: The number of implant samples subjected to fatigue testing according to ISO 14801 is not specified (e.g., "n="). The standard usually specifies minimum sample sizes.
  • For other tests (Biocompatibility, Sterilization, Shelf Life, Bacterial Endotoxin, Surface Modification), the sample sizes are not provided as these were either leveraged from the predicate device or conducted per standard protocols without explicit counts in this document.
• Data Provenance: The document generally refers to "non-clinical testing data." Specific countries of origin for the non-clinical testing are not provided. The main submitter (Izenimplant Co., Ltd.) is from the Republic of Korea. The testing itself would typically be performed by accredited labs. The studies were retrospective in the sense that data from already cleared predicate devices were leveraged. The fatigue testing for the subject device was newly performed, making it prospective for that specific test on the new design.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and the Qualifications of Those Experts

This information is not applicable in this context. Since this is a 510(k) submission based on non-clinical testing for substantial equivalence, there is no "ground truth" derived from expert clinical assessment of patient data (e.g., radiologists interpreting images) for a "test set" in the way it would be for an AI/CADe device. The "ground truth" for non-clinical tests is established by adhering to recognized international standards and laboratory protocols.

4. Adjudication Method for the Test Set

This information is not applicable. There was no "test set" in a clinical diagnostic sense requiring expert adjudication. Non-clinical tests typically involve objective measurements according to defined standards.

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

This information is not applicable. The device is an endosseous dental implant, not an AI or CADe diagnostic tool. Therefore, MRMC studies involving human readers and AI assistance are not relevant to this submission.

6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) Was Done

This information is not applicable. The device is a physical medical implant, not a software algorithm.

7. The Type of Ground Truth Used

For non-clinical tests, the "ground truth" is defined by the established international or national standards and protocols for each test (e.g., ISO 14801 for fatigue testing, ISO 10993 for biocompatibility). The results are compared against these benchmarks or against the performance of predicate devices tested under the same conditions.

8. The Sample Size for the Training Set

This information is not applicable. The device is an endosseous dental implant. There is no concept of a "training set" as would be used for machine learning models.

9. How the Ground Truth for the Training Set Was Established

This information is not applicable. As there is no training set for a machine learning model, there is no ground truth established for one.
