Intended Use

The ARi ExCon Implant System is intended to be surgically placed in the maxillary or mandibular molar areas for the purpose providing prosthetic support for dental restorations (Crown, bridges, and overdentures) in partially or fully edentulous individuals. It is used to restore a patient's chewing function in the following situations and with the clinical protocols:

  • Delayed loading

  • Immediate loading when good primary stability is achieved and with appropriate occlusal loading.

For TiGEN Abutment and ZrGEN Abutment, all digitally designed abutments for use with TiGEN Abutment and ZrGEN Abutment are intended to be sent to a MegaGen-validated milling center for manufacture.

Device Description

The ARi ExCon Implant is a substructure of a dental implant system made of CP Ti Grade 4 with the surface treated by SLA method. It is intended to be placed in the maxillary or mandibular areas to restore masticatory function.
The Abutments are prosthetic components directly or indirectly connected to the endosseous dental implant and are intended for use as an aid in prosthetic rehabilitation, allows single & multiple prosthetic restorations.

AI/ML Overview

The provided text is an FDA 510(k) premarket notification summary for the "ARi ExCon Implant System." It details various components of the dental implant system (implants, cover screws, healing abutments, etc.) and compares them to predicate and reference devices to demonstrate substantial equivalence.

However, the document does not contain information about a study that proves the device meets specific acceptance criteria in the context of an AI/human-in-the-loop performance study, such as an MRMC study. The "Performance test" section on page 25-26 only mentions fatigue testing according to ISO 14801 and "Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Implant Abutment" to evaluate the performance of subject devices (implant components), and that test results met pre-set criteria. This is a mechanical performance test, not a clinical or human-reader study.

Therefore, I cannot fulfill the request for information regarding:

  1. A table of acceptance criteria and reported device performance (in the context of AI/human performance).
  2. Sample size for the test set and data provenance.
  3. Number of experts and their qualifications for ground truth.
  4. Adjudication method.
  5. MRMC comparative effectiveness study results or effect size.
  6. Standalone (algorithm-only) performance.
  7. Type of ground truth used (clinical/AI performance).
  8. Training set sample size.
  9. How training set ground truth was established.

The document primarily focuses on demonstrating substantial equivalence of the dental implant components through material comparisons and mechanical bench testing to predicate and reference devices, not on the performance of a medical AI device or human-in-the-loop performance with AI assistance.

§ 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.
