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 procedures, for single or multiple unit restorations, and may be loaded immediately when good primary stability is achieved and with appropriate occlusal loading. Multiple tooth applications may be rigidly splinted.
The subject Titamax Ti EX Acqua implants are provided in the same design variants as the predicate Titamax Ti EX implants. The only difference is the application of the Acqua hydrophilic surface treatment in place of the NeoPoros surface finish. The Titamax Ti EX Acqua are provided in two endosseous diameters (3.75 and 4.0 mm), one platform diameter (4.1 mm), and five lengths (9, 11, 13, 15, and 17 mm).
The subject Ti Drive Acqua implants have the same tapered, single thread design variants as the predicate CM Drive implants and the same external hex abutment interface and internal geometry as the predicate HE series implants.

The provided text describes the Neodent Implant System's 510(k) summary (K133592) and its substantial equivalence determination by the FDA. However, it does not contain information about acceptance criteria, specifics of a study proving device performance against acceptance criteria, or details regarding ground truth establishment, sample sizes for test/training sets, expert qualifications, or adjudication methods in the context of an AI/algorithm-based device as requested in the prompt.
The document primarily focuses on demonstrating the substantial equivalence of the Neodent Implant System to legally marketed predicate devices based on design, materials, surface treatment, and intended use.
Here's a breakdown of what can be extracted and what is missing based on your specific questions:
1. Table of Acceptance Criteria and Reported Device Performance:
This information is not available in the provided text. The document states that "Non-clinical data submitted, referenced, or relied upon to demonstrate substantial equivalence include engineering analysis and dimensional analysis. Bench testing and animal testing were submitted to characterize the Acqua surface." However, it does not specify any quantitative acceptance criteria or the reported performance metrics against those criteria.
2. Sample Size Used for the Test Set and Data Provenance:
This information is not available. The document mentions bench testing and animal testing but provides no details on sample sizes or data provenance (country of origin, retrospective/prospective) for these tests.
3. Number of Experts Used to Establish Ground Truth and Qualifications:
This information is not available. The document does not describe any process of establishing ground truth by experts, as it's not detailing a diagnostic AI/algorithm.
4. Adjudication Method for the Test Set:
This information is not available. Adjudication methods are typically relevant for human review of results, which is not described here.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done and Effect Size:
No. The document explicitly states: "Clinical data were not submitted in this premarket notification." Therefore, an MRMC study comparing human readers with and without AI assistance was not performed or reported.
6. If a Standalone (algorithm only without human-in-the-loop performance) was done:
No. The device is a physical dental implant system, not a software algorithm. Therefore, "standalone" performance in the context of an algorithm is not applicable or discussed.
7. The Type of Ground Truth Used:
This information is not available. For a physical device, "ground truth" often refers to established engineering specifications, material properties, or biological outcomes. While the document mentions demonstrating substantial equivalence through "engineering analysis and dimensional analysis" and characterizing the "Acqua surface" through "bench testing and animal testing," it does not explicitly define what "ground truth" was used or how it was established for these tests.
8. The Sample Size for the Training Set:
This information is not available. As the device is not an AI/algorithm, there is no concept of a "training set" in the context of the provided document.
9. How the Ground Truth for the Training Set Was Established:
This information is not available (not applicable, as there's no training set).
Summary of what is present:
- Device Name: Neodent Implant System
- Intended Use: "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 procedures, for single or multiple unit restorations, and may be loaded immediately when good primary stability is achieved and with appropriate occlusal loading. Multiple tooth applications may be rigidly splinted."
- Basis for Approval: Substantial equivalence to previously cleared predicate devices (K101207, K101945, K123022, K133510, and K033984 for the SLActive surface).
- Performance Data Submitted: Non-clinical data including engineering analysis, dimensional analysis, bench testing, and animal testing to characterize the Acqua surface.
- Clinical Data: "Clinical data were not submitted in this premarket notification."
The provided text describes a regulatory submission for a physical medical device (dental implants), not a diagnostic AI or algorithm. Therefore, many of the questions related to AI/algorithm validation (ground truth, expert adjudication, MRMC studies, training/test sets) are not addressed in this document.

(a)
Identification. An endosseous dental implant is a prescription device made of a material such as titanium or titanium alloy that 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 a patient's chewing function.(b)
Classification. (1) Class II (special controls). The device is classified as class II if it is a root-form endosseous dental implant. The root-form endosseous dental implant is characterized by four geometrically distinct types: Basket, screw, solid cylinder, and hollow cylinder. The guidance document entitled “Class II Special Controls Guidance Document: Root-Form Endosseous Dental Implants and Endosseous Dental Implant Abutments” will serve as the special control. (See § 872.1(e) for the availability of this guidance document.)(2)
Classification. Class II (special controls). The device is classified as class II if it is a blade-form endosseous dental implant. The special controls for this device are:(i) The design characteristics of the device must ensure that the geometry and material composition are consistent with the intended use;
(ii) Mechanical performance (fatigue) testing under simulated physiological conditions to demonstrate maximum load (endurance limit) when the device is subjected to compressive and shear loads;
(iii) Corrosion testing under simulated physiological conditions to demonstrate corrosion potential of each metal or alloy, couple potential for an assembled dissimilar metal implant system, and corrosion rate for an assembled dissimilar metal implant system;
(iv) The device must be demonstrated to be biocompatible;
(v) Sterility testing must demonstrate the sterility of the device;
(vi) Performance testing to evaluate the compatibility of the device in a magnetic resonance (MR) environment;
(vii) Labeling must include a clear description of the technological features, how the device should be used in patients, detailed surgical protocol and restoration procedures, relevant precautions and warnings based on the clinical use of the device, and qualifications and training requirements for device users including technicians and clinicians;
(viii) Patient labeling must contain a description of how the device works, how the device is placed, how the patient needs to care for the implant, possible adverse events and how to report any complications; and
(ix) Documented clinical experience must demonstrate safe and effective use and capture any adverse events observed during clinical use.
