MIS Dental Implant System is intended to be surgically placed in the bone of the upper or lower jaw arches to provide support for prosthetic devices, such as artificial teeth, in order to restore masticatory function. When a one-stage surgical procedure is applied, the implant may be immediately loaded when good primary stability is achieved and the occlusal load is appropriate. Narrow implants (Ø3.3mm) are indicated for use in surgical and restorative applications for placement only in the mandibular central, lateral incisor and maxillary lateral incisor regions of partially edentulous jaws, to provide support for prosthetic devices such as artificial teeth. Mandibular central and lateral incisors must be splinted if using two or more narrow implants adjacent to one another. MIS LYNX short implants are indicated for delayed loading only.

The two additional implant size offerings which are being added to the predicate MIS LYNX Conical Connection Dental Implant System (K241692), and are the subject of this submission, consist of a standard platform, 4.20 mm diameter implant and a wide platform, 5.00 mm diameter implant, each available in a 6 mm length.

The proposed implant offerings, as their predicate K241692, are root-form, bone-level, self-tapping, two-piece, screw-type implants which are intended for one- or two-stage dental implant procedures and are used in the upper or lower jaw for supporting tooth replacement to restore chewing function.

Each implant offering is provided with a compatible cover screw based on the implant platform (standard and wide). The cover screws are identical to those cleared in K241692 and are intended to be used in a two-stage surgical procedure as temporary components to the proposed endosseous implant to allow healing of the soft tissue. The cover screw is screwed into the implant's internal thread and the gums are sutured over the cover screw. The cover screw's purpose is to let the osseointegration begin without any forces being applied to the implant. After a healing period, the cover screw is exposed and is then removed and replaced by either a healing cap or an abutment.

The implants and cover screws 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 proposed implants feature an outer profile which has a coronal section which is cylindrical and an apical section which is conical. The outer threads are designed so the implant has a self-drilling property. The implant's geometric design includes a dual thread feature and spiral channels (flutes) stemming from the apex. These spiral channels are designed to enable insertion torque reduction when applying reverse torque. The proposed implant design also includes circumferential grooves at the coronal area which are called "micro-rings". These horizontal micro-rings are designed to increase the BIC (Bone to Implant Contact) of the implant with the bone. The proposed implants feature a round (cylindrical) neck.

The proposed MIS LYNX Conical Connection Implants have a conical connection with an anti-rotation index of six positions and an internal thread for cover screws, screw-retained abutments and screwed healing caps. The implant-abutment connection surface of the proposed implants is anodized for color coding purposes to indicate the platform: purple for standard platform implants, and green for wide platform implants. The cover screws are also anodized for platform color coding.

The proposed implants are packaged in either a dry or wet package. Implants packaged in the wet packaging configuration are packaged in NaCl solution and are not anodized. The liquid environment is intended to maintain the super-hydrophilic (contact angle exhibited by water in contact with the surface is equal to zero degrees) property of the proposed dental implants until the implants are installed in patients.

This 510(k) clearance letter pertains to an Endosseous Dental Implant System, which is a physical medical device, not a software-driven AI device. Therefore, the concepts of acceptance criteria, study data, expert adjudication, MRMC studies, standalone algorithm performance, ground truth establishment for AI models, and training set sizes are not applicable to the information provided.

The document focuses on demonstrating substantial equivalence to predicate devices rather than proving performance against specific acceptance criteria in the context of an AI-driven system. The "acceptance criteria" here are implicitly the standards and performance levels demonstrated by the predicate and reference devices, as well as relevant ISO and ASTM standards.

Here's an analysis of the provided information, framed as closely as possible to your request, but acknowledging the device type:

Device: MIS LYNX Conical Connection Implant System

This device is an endosseous dental implant system, a physical medical device. The FDA clearance is based on demonstrating substantial equivalence to legally marketed predicate devices, not on the performance of an AI algorithm.

Table of Acceptance Criteria (Inferred from testing) and Reported Device Performance:

Regarding the other requested information (primarily relevant to AI/Software-as-a-Medical-Device):

2. Sample size used for the test set and the data provenance: Not applicable. The testing done was laboratory-based mechanical and MR safety testing, not evaluation of an AI model with a clinical test set. The implant dimensions analyzed for surface area were "smallest implant length (6 mm) and diameter (4.20 mm)" for proposed and reference devices. Pull-out testing and fatigue testing would have involved a number of physical samples per test, but specific quantities are not detailed in this summary.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. Ground truth as typically understood for AI (e.g., expert labels on medical images) is not relevant here. The "ground truth" for mechanical testing is established by physical measurements and engineering principles.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not applicable.

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 is a physical dental implant, not an AI assistance system for human readers.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc): For mechanical properties, the "ground truth" is derived from established engineering test methods and their performance metrics (e.g., load at failure, cycles to failure). For MR safety, it's compliance with established safety limits for magnetic fields.

8. The sample size for the training set: Not applicable. There is no AI model or training set mentioned.

9. How the ground truth for the training set was established: Not applicable.

In summary: The provided document is an FDA 510(k) clearance letter for a conventional physical medical device (dental implant system). The evaluation and clearance process for such devices involve demonstrating safety and effectiveness by showing substantial equivalence to existing legally marketed devices, typically through non-clinical (laboratory) testing, materials characterization, and compliance with recognized standards. The concepts and terminology in your request are largely tailored to the evaluation of AI/Machine Learning-driven medical devices, which is not what this document addresses.

The proposed MIS LYNX Conical Connection Dental Implants are intended for one- or two-stage dental implant procedures and are used in the upper or lower jaw for supporting tooth replacement to restore chewing function. The proposed dental implants have an internal conical connection with an anti-rotation index of six positions for standard and wide platforms and four positions for narrow platform. The proposed implants and cover screw are manufactured from titanium alloy (Ti-6A1-4V ELI complying with standard ASTM F136-13 - Standard Specification for Wrought Titanium-6Aluminum-4Vanadium ELI (Extra Low Interstitial) Alloy for Surgical Implant). The 3.3 mm diameter size implant is available in 10, 11.5, 13, and 16 mm lengths while the 3.75, 4.2, and 5.0 mm diameter size implants are available in 8, 10, 11.5, 13, and 16 mm lengths. The proposed implants feature an outer profile which has a coronal half which is cylindrical and an apical half which is conical. The threads are designed so the implant has a self-drilling property. The geometric design also includes spiral channels (flutes) stemming from the apex. These spiral channels are designed to enable insertion torque reduction when applying reverse torque. The proposed implant design also includes circumferential grooves at the coronal area which are called "micro-rings". These horizontal micro-rings are designed to increase the BIC (Bone to Implant Contact) of the implant with the bone. The proposed implants also feature a triangular neck ("V-Cut''). The gaps around the sides of the implant neck are designed to result in an open, compression free zone. The implant-abutment connection surface of the proposed MIS LYNX Conical Connection Implant is anodized for color coding to indicate the platform: yellow for narrow platform implants, purple for standard platform implants, and green for wide platform implants. The proposed implants are packaged in either a dry or wet package. Implants packaged in the wet packaging configuration are packaged in NaCl solution and are not anodized. The liquid environment is intended to maintain the super-hydrophilic (contact angle exhibited by water in contact with the surface is equal to zero degrees) property of the proposed dental implants until the implants are installed in the patients. Cover screws are intended to be used in a two-stage surgical procedure as temporary components to the proposed endosseous implant to allow healing of the soft tissue. They are inserted into the implant and the gums are sutured over it. Their purpose is to let the osseointegration begin without any forces being applied to the implant. After a healing period, the cover screw is exposed and removed, and replaced by either a healing cap or an abutment. The cover screws are also anodized for color coding.

The provided document is a 510(k) Summary for the MIS LYNX Conical Connection Implant System. It details the device, its intended use, and a comparison to predicate devices, focusing on demonstrating substantial equivalence through non-clinical testing.

However, the document does not describe a study that proves the device meets specific acceptance criteria based on clinical performance or an AI/algorithm-driven component. Instead, it focuses on non-clinical testing (fatigue, biocompatibility, sterilization, shelf-life, and MRI compatibility) to demonstrate the safety and effectiveness of the dental implant system itself, relative to predicate devices. There is no mention of an AI component, human-in-the-loop study, or any performance metrics like accuracy, sensitivity, or specificity that would be typical for an AI-driven medical device.

The section titled "8. Clinical Tests Summary and Conclusion" explicitly states: "Not applicable. There are no clinical tests submitted, referenced, or relied on in the 510(k) for a determination of substantial equivalence."

Therefore, based solely on the provided text, I cannot generate a response that fulfills the request for acceptance criteria and study details related to an AI/algorithm's performance because such information is not present in the document. The device in question is a dental implant system, not a software device that would typically have acceptance criteria focused on AI performance metrics.

To directly answer your prompt, given the provided text:

1. A table of acceptance criteria and the reported device performance:
Not applicable. The document describes non-clinical testing for a dental implant system, not performance metrics for an AI/algorithm. The "acceptance criteria" for the non-clinical tests are implied as meeting the standards (e.g., ISO 14801:2016 for fatigue, ISO 10993 series for biocompatibility) and demonstrating equivalence or superiority to predicate devices. For example, "Fatigue testing... confirms that the proposed device is similar or exceeds performance when compared to the predicate device (K172505) and reference (K112162) devices." And "Test results met acceptance criteria" for shelf-life testing. However, specific numerical acceptance criteria and reported performance values for each of these tests are not provided in a table format within this summary.

2. Sample sized used for the test set and the data provenance:
Not applicable for an AI test set. The document refers to samples used for non-clinical tests (e.g., implants for fatigue testing, materials for biocompatibility). Specific sample sizes are not detailed, but the tests are conducted on representative devices. Data provenance is implied as being from the manufacturer's internal testing as part of the 510(k) submission.

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 an AI/imaging device requiring expert ground truth for interpretation.
