Indications for Use

Nobel Biocare's NobelReplace Hexagonal Implants are endosseous implants intended to be surgically placed in the bone of the upper or lower jaw arches to provide support for prosthetic devices, such as an artificial tooth, in order to restore patient esthetics and chewing function. The NobelReplace Hexagonal Implants are indicated for single or multiple unit restorations. The NobelReplace Hexagonal Implants can be used in splinted or non-splinted applications. The NobelReplace Hexagonal Implants may be placed immediately and put into immediate function provided that initial stability requirements detailed in the manual are satisfied.

Device Story

NobelReplace Hexagonal Implants are threaded, root-form endosseous dental implants. Surgically placed in upper or lower jaw bone by dental professionals to support prosthetic devices (e.g., artificial teeth). Restores esthetics and chewing function. Device features internal hexagonal connection, modified from predicate internal square connection. Used in clinical dental settings. Provides structural foundation for dental prosthetics; enables immediate loading if stability criteria are met.

Clinical Evidence

No clinical data provided. Substantial equivalence based on design similarity and intended use.

Technological Characteristics

Threaded, root-form endosseous dental implant. Features internal hexagonal connection. Material and sterilization details not specified in provided text. Standalone mechanical device.

Indications for Use

Indicated for partially or fully edentulous patients requiring single or multiple unit restorations in upper or lower jaw arches. Suitable for splinted or non-splinted applications. May be placed immediately and put into immediate function if initial stability requirements 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.

Legally Marketed Device(s): NobelReplace Tapered Conical Connection (K062566)

## Device Description:

NobelReplace Hexagonal Implants are threaded, root-form dental implants intended for use in the upper and lower jaw arches to support prosthetic devices, such as an artificial tooth, in order to restore esthetics and chewing function to partially or fully edentulous patients.

The NobelReplace Hexagonal Implants are similar in design to the implants cleared under NobelReplace Tapered Conical Connection, K062566. The predicate internal square was changed to internal bexagonal connection.

## Indications for Use:

Nobel Biocare's NobelReplace Hexagonal Implants are endosseous implants intended to be surgically placed in the bone of the upper or lower jaw arches to provide support for prosthetic devices, such as an artificial tooth, in order to restore patient esthetics and chewing function. The NobelReplace Hexagonal Implants are indicated for single or multiple unit restorations. The NobelReplace Hexagonal Imvlagonal be used in splinted or non-splinted applications. The NobelReplace Hexagonal Implants may be placed immediately and put into immediate function provided that initial stability requirements detailed in the manual are satisfied.

Dear Dr. Leung:

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 (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. 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.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
