The NR Line Implants System is indicated for use in surgical and restorative applications for placement in the bone of the upper or lower jaw to provide support for prosthetic devices, such as artificial teeth, in order to restore the patient's chewing function. NR Line Implant System is indicated also for immediate loading when good primary stability is achieved and with appropriate occlusal loading.
Not Found
Unfortunately, I cannot fulfill your request to describe the acceptance criteria and the study that proves the device meets them from the provided text.
The document is a 510(k) premarket notification letter from the FDA regarding the "NR Line Implant System." This type of document primarily confirms that the device has been found substantially equivalent to a legally marketed predicate device. It does not contain information about acceptance criteria, detailed study designs, performance metrics of the device itself (beyond its indications for use), sample sizes for testing or training, expert qualifications, adjudication methods, or specific comparative effectiveness study results.
The letter focuses on regulatory compliance, outlining responsibilities under the Act (like registration, labeling, adverse event reporting, and good manufacturing practices). The "Indications for Use" section describes how the device is intended to be used, but this is not a performance study or a list of acceptance criteria.
To provide the information you're asking for, I would need a different type of document, such as a summary of safety and effectiveness data (which may be part of the full 510(k) submission but is not included in this letter), a clinical study report, or a detailed device specification document.
§ 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.
