Intended Use

The Zuga™ Dental Implant System is indicated for immediate or delayed implant placement for surgical and restorative applications in maxillary and/or mandibular arches to support prosthetic devices, such as artificial teeth, crowns, bridges, and overdentures. The Zuga™ Dental Implant System is indicated for immediate loading when good primary stability is achieved and with appropriate occlusal loading.

Device Description

The Zuga™ Dental Implant System includes endosseous dental implants, sealing caps, healing caps, dental implant abutments, and fixation screws in a variety of sizes to accommodate differing patient anatomy. Implantation is suitable for one-or two-stage procedures. Endosseous implants are bone level, self-tapping, root-form, threaded. The threaded surface is blasted, then passivated. Sizematched anterior and posterior abutments are offered. Thes are fastened to the implant using a fixation screw. Sealing caps and healing caps provide protection to the abutment connection threads during endosseous and gingival healing. The implants are provided sterile, the remaining components must be sterilized prior to use.

AI/ML Overview

The provided text describes a 510(k) premarket notification for the Zuga™ Dental Implant System. This type of submission focuses on demonstrating substantial equivalence to legally marketed predicate devices, rather than proving that the device meets a set of specific acceptance criteria through clinical performance metrics like sensitivity, specificity, or accuracy, as would be common for AI-driven diagnostic devices.

Therefore, the document does not contain the information requested regarding acceptance criteria in terms of performance metrics for an AI/ML device, nor does it detail a study proving the device meets such criteria with respect to AI performance.

Instead, the "Performance Data" section ([15]) focuses on biological and mechanical compatibility/safety testing, which is standard for medical devices like dental implants. These tests are designed to show that the physical device itself is safe and performs as intended, not to evaluate an AI algorithm's diagnostic or predictive capabilities.

Here's an breakdown of the information present and what's missing, based on the prompt's requirements:

1. A table of acceptance criteria and the reported device performance:

  • Present: The document lists various tests performed and their outcomes which act as "acceptance criteria" for a physical medical device. These are:
    • Static fatigue tests and dynamic fatigue tests (per ISO 14801 and FDA Guidance): "The results show that the Zuga™ Dental Implant System has sufficient mechanical strength for the intended clinical application."
    • Cytotoxicity testing (per ISO 10993-5 and USP ): "The results showed that the Zuga™ Dental Implant System received a passing score and is thus acceptable for clinical application."
    • Sterility tests (per ISO 10993, ISO 11137-1, 11137-2, ISO 17665-1, 17665-2): "yielded no difference in performance between the Zuga™ Dental Implant System and the predicate device."
    • LAL (Limulus Amebocyte Lysate) bacterial endotoxin tests (per ISO 10993 and USP , ): "yielded a EU/Device value that was less than the established acceptance criteria of 20 EU/Device".
    • Shelf life tests (per ISO 11607): "established the shelf life to be five years provided the sterile seal is not breached."
  • Missing (for an AI/ML device context): Specific performance metrics like sensitivity, specificity, accuracy, AUC, FROC, etc., and their corresponding acceptance thresholds.

2. Sample sized used for the test set and the data provenance:

  • Present: For LAL tests, it states: "The sampling plan consists of selecting 3% of the batch up to a maximum of 10 samples to be pooled for testing."
  • Missing (for an AI/ML device context): Sample size for a "test set" of patient data (e.g., medical images, clinical records) for an AI algorithm. Data provenance (country of origin, retrospective/prospective) is not applicable or mentioned for these physical/biological tests.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts:

  • Missing: This information is not relevant to the mechanical/biological testing of a physical implant. It would be crucial for an AI/ML device based on clinical data.

4. Adjudication method (e.g. 2+1, 3+1, none) for the test set:

  • Missing: Not applicable to the presented data.

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:

  • Missing: Not applicable. This device is a physical dental implant, not an AI-assisted diagnostic tool.

6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done:

  • Missing: Not applicable.

7. The type of ground truth used (expert concensus, pathology, outcomes data, etc):

  • Present (for physical device tests): The "ground truth" here is adherence to international standards (ISO, ASTM) and USP guidelines for mechanical strength, biocompatibility, sterilization, and endotoxin levels.
  • Missing (for an AI/ML device context): Clinical ground truth established by experts or pathology for diagnostic purposes.

8. The sample size for the training set:

  • Missing: Not applicable, as this is not an AI/ML device.

9. How the ground truth for the training set was established:

  • Missing: Not applicable.

In summary: The provided document is an FDA 510(k) clearance letter for a physical dental implant system. Its "acceptance criteria" and "performance data" relate to the mechanical, chemical, and biological safety and efficacy of the implant itself, demonstrated through adherence to various international and US standards. It contains no information relevant to the development, testing, or performance of an AI/ML device.

§ 872.3640 Endosseous dental implant.

(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.
