The Noris LONGY and LONGY-N implants are indicated for splinted restorations in the maxilla, utilizing a minimum of two implants to support fixed or removable prosthetic devices with partially or fully edentulous upper jaws, and may be suitable for immediate loading when good primary stability is achieved and with appropriate occlusal loading.
The procedure can be accomplished in a one-stage or two-stage surgical operation.
The subject dental implant devices are single use devices, provided sterile by Gamma Radiation, made of Titanium alloy Ti-6Al-4V ELI (ASTM F136). The LONGY Implants and LONGY-N Implants bare internal hex connection, diameters of 3.75 and 4.0mm and lengths of 18, 20, 22 and 25 mm. The Noris LONGY and LONGY-N implants are indicated for splinted restorations in the maxilla, utilizing a minimum of two implants to support fixed or removable prosthetic devices in patients with partially or fully edentulous upper jaws, and may be suitable for immediate loading when good primary stability is achieved. The procedure can be accomplished in a one-stage surgical operation. All implants are appropriate for immediate loading when good primary stability is achieved and with appropriate occlusal loading.
LONGY and LONGY-N dental implants are compatible with FDA cleared Noris Medical Ltd. Internal Hex platform abutments and superstructures only intended for multiple-unit loading, provided that they do not exceed an angulation of 30° (≤30).
The provided text is a 510(k) Premarket Notification from Noris Medical Ltd. for their LONGY Implant and LONGY-N Implant. It primarily focuses on demonstrating substantial equivalence to legally marketed predicate devices rather than proving a device meets specific acceptance criteria through a study involving AI or human reader performance.
Therefore, the document does not contain the information required to answer the prompt's request for acceptance criteria and a study proving device performance against those criteria, especially in the context of AI assistance or human reader improvement.
The document details the following:
- Device Name: LONGY Implant and LONGY-N Implant
- Regulation Number/Name: 21 CFR 872.3640 (Endosseous Dental Implant)
- Regulatory Class: Class II
- Product Code: DZE
- Indications for Use: Splinted restorations in the maxilla, utilizing a minimum of two implants to support fixed or removable prosthetic devices in patients with partially or fully edentulous upper jaws, suitable for immediate loading when good primary stability is achieved and with appropriate occlusal loading. Can be accomplished in a one-stage or two-stage surgical operation.
- Predicate Devices: Neodent Implant System - GM Helix LG ® (K190958 - Primary), Noris Medical Ltd. - TUFF (K140440 - Reference), Neodent Implant System - Zygoma GM (K190718 - Reference), Noris Medical Ltd. - Zygomatic Implants (K151909 - Reference), Noris Medical Ltd. - MBI Dental Implant System (K153043 - Reference).
- Device Description: Single-use, sterile (Gamma Radiation), made of Titanium alloy Ti-6Al-4V ELI (ASTM F136), internal hex connection, diameters of 3.75 and 4.0mm, lengths of 18, 20, 22, and 25 mm.
- Performance Data: Fatigue tests per ISO 14801, biocompatibility, sterilization validation, shelf-life testing, mechanical testing, and MRI review. These tests are to demonstrate substantial equivalence, not to establish performance against specific clinical acceptance criteria in a user-performance or AI-assisted context.
Missing Information (as per the prompt's requirements):
- A table of acceptance criteria and the reported device performance: Not provided in the context of clinical endpoints or user performance. The performance data discussed (fatigue, biocompatibility, etc.) are for device safety and mechanical integrity, not for clinical diagnostic or treatment performance against specific numerical acceptance criteria.
- Sample size used for the test set and the data provenance: No test set is described for evaluating AI or human reader performance.
- Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable as no AI/human reader study is described.
- Adjudication method for the test set: Not applicable.
- If a multi-reader multi-case (MRMC) comparative effectiveness study was done, and its effect size: Not mentioned.
- If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not mentioned. This document is about a physical dental implant, not AI software.
- The type of ground truth used (expert consensus, pathology, outcomes data, etc.): Not applicable to the presented data (which is about implant mechanical and material properties).
- The sample size for the training set: Not applicable (no AI/machine learning model discussed).
- How the ground truth for the training set was established: Not applicable.
In summary, the provided document is a regulatory submission for a dental implant, focusing on its physical and material properties to demonstrate substantial equivalence for market clearance. It does not contain information related to AI or human-in-the-loop studies, nor does it define acceptance criteria in the manner requested by the prompt for such studies.
§ 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.
