Intended Use

The NSI Implant System is intended to be implanted in the upper or lower jaw arches to provide support for fixed or removable dental prostheses in a single tooth, partially edentulous prostheses, or full arch prostheses. It further adds the option for immediate placement and function on single and splinted multiple unit restorations when good primary stability is achieved and with appropriate occlusal loading, to restore chewing function. This implant is not intended, nor should it be used, in conjunction with an angled abutment.

Device Story

NSI Hexed and Non-Hexed Endosseous Implant System consists of screw-type dental implants and abutments. Used by dental professionals in clinical settings to support fixed or removable dental prostheses. Implants are surgically placed into the upper or lower jaw to restore chewing function. System allows for immediate placement and function for single or splinted multiple unit restorations, provided primary stability and proper occlusal loading are achieved. Device output is the physical support structure for dental prostheses. Benefits include restoration of oral function and aesthetics for edentulous patients. Not for use with angled abutments.

Clinical Evidence

No clinical studies were conducted or deemed necessary. Evidence consists of bench testing, specifically fatigue testing performed in accordance with the FDA Class II Special Controls Guidance Document: Root-Form Endosseous Dental Implants and Endosseous Dental Abutments (May 12, 2004).

Technological Characteristics

Screw-type endosseous dental implants and abutments. Materials: ASTM F67-95 Grade III or Grade IV Titanium. Design includes hexed and non-hexed configurations. Sterilization method not specified. No software or electronic components.

Indications for Use

Indicated for patients requiring dental prostheses (single tooth, partially edentulous, or full arch) in the upper or lower jaw. Supports immediate placement and function if primary stability and appropriate occlusal loading are achieved. Contraindicated for use with angled abutments.

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.
