• Attributes: Therapeutic

Intended Use

The NB Mini Implant System is indicated for use in surgical and restorative applications for placement in the mandibular central, lateral incisor and maxillary lateral incisor regions of partially edentulous jaws where the horizontal space is limited by the adjacent teeth and roots, to provide support for prosthetic devices, such as artificial teeth, in order to restore the patient's chewing function. The NB Mini Implant System is indicated also for immediate loading when good primary stability is achieved and with appropriate occlusal loading.

Device Story

NB Mini Implant System comprises endosseous dental implants (fixtures) and associated abutments (cover screws, healing abutments, scan healing abutments, cemented/angled abutments, screws). Fixtures are placed into alveolar bone to replace missing teeth; abutments connect to fixtures to support prosthetic restorations. Used in dental clinics by trained clinicians. Fixtures feature SLA surface treatment; internal hex/morse taper connection. Scan healing abutments include machined markings for digital impression capture via intraoral scanners. System supports immediate loading. Benefits include restoration of chewing function in narrow spaces where standard implants may not fit.

Clinical Evidence

Bench testing only. Included fatigue testing (ISO 14801), Bone to Implant Contact (BIC) analysis, surface area analysis, and pullout force testing compared to predicate K190849. Biocompatibility demonstrated via reference to K213506. Sterilization validated per ISO 11137-1/2 and ANSI/AAMI ST79. MRI safety evaluated via scientific rationale and literature.

Technological Characteristics

Materials: Ti-6Al-4V Eli (ASTM F136). Surface: SLA (fixtures), TiN coating (select abutments). Connection: Internal hex/morse taper. Dimensions: Fixture diameters 3.2-3.5mm. Sterilization: Gamma (sterile components) or end-user moist heat. Connectivity: None (mechanical device).

Indications for Use

Indicated for partially edentulous patients requiring dental implants in mandibular central, lateral incisor, and maxillary lateral incisor regions where horizontal space is limited. Supports prosthetic devices to restore chewing function. Indicated for immediate loading if primary stability and occlusal conditions are met.

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.

Dear Won-Yi Choi:

We have reviewed your section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (the Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database available at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
