Indications for Use
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.
Device Story
The NR Line Implant System consists of endosseous dental implants designed for surgical placement into the maxilla or mandible. These implants provide a foundation for prosthetic devices, such as artificial teeth, to restore chewing function. The system is intended for use by dental professionals in clinical settings. It supports both delayed and immediate loading protocols, provided that adequate primary stability is achieved during surgical placement and occlusal loading is managed appropriately. The device functions as a mechanical anchor within the jawbone to support restorative dental prosthetics.
Clinical Evidence
No clinical data provided; substantial equivalence is based on bench testing and design characteristics.
Technological Characteristics
Endosseous dental implant system; intended for surgical placement in the jawbone. Mechanical device; no software or electronic components. Sterilization and material specifications are consistent with standard dental implant requirements.
Indications for Use
Indicated for patients requiring dental restoration via prosthetic support in the upper or lower jaw. Suitable for immediate loading given sufficient primary stability and appropriate occlusal loading.
Regulatory Classification
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.
Special Controls
*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.
