Indications for Use
The Neodent Implant System is intended to be surgically placed in the bone of the upper or lower jaw to provide support for prosthetic devices, such as artificial teeth, to restore chewing function. It may be used with single-stage or two-stage procedures, for single or multiple unit restorations, and may be loaded immediately when good primary stability is achieved and with appropriate occlusal loading.
Device Story
Neodent Implant System - GM Helix Implants 7.0 are endosseous dental implants; surgically placed in upper or lower jaw bone to support prosthetic devices (artificial teeth) for chewing function restoration. Implants feature conical body/apex, rounded apex, and trapezoidal-profile double threads; manufactured from commercially pure titanium (Grade 4). Provided sterile via gamma irradiation for single use. Operated by dental surgeons in clinical settings. Output is a stable base for prosthetic abutments. Clinical benefit includes restoration of oral function and aesthetics. Device integrates with existing Neodent GM line abutments.
Clinical Evidence

Sterilization validated per ISO 11137-1/2 (SAL 10^-6). Shelf life validated via accelerated aging (ASTM F1980) and packaging integrity tests (ASTM F88, F1929, F2096). Endotoxin testing performed per USP <161>.
Technological Characteristics
Material: Commercially pure titanium Grade 4 (ASTM F67). Design: Conical body/apex, rounded apex, trapezoidal double threads. Interface: Morse Taper with internal hexagonal indexer (GM line). Dimensions: 7.0mm diameter; 8-13mm lengths. Sterilization: Gamma irradiation (25 kGy). Single-use, non-reusable.
Indications for Use

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

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 Jennifer Jackson:
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. 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 located 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.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to 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.

## PERFORMANCE DATA
### Biocompatibility
Biocompatibility sample preparation was made according to ISO 10993-12. Biological Safety Assessment guided by ISO 10993-1, Cytotoxicity testing was performed per ISO 10993-5 and Chemical characterization was performed per ISO 10993-18. The subject implants are made of unalloyed titanium, Grade 4, conforming to ASTM F67 Standard Specification for Unalloyed Titanium for Surgical Implant Applications (UNS R50250, UNS R50400, UNS R50550, UNS R50700), the same type of titanium used for fabrication of the predicate devices cleared under K163194 and K180536. The subject devices undergo to the same manufacturing processes to the cited predicate devices. The subject devices do not present a new worst case for biocompatibility and therefore, the predicate and reference device testing are relied upon for determining substantial equivalence.
### Mechanical testing
Dynamic fatigue test per ISO 14801 was performed to determine the fatigue strength for the dental implant system, according to FDA Guidance. The tested subject devices exhibit a level of performance equivalent to that reviewed for the predicate devices.
Insertion torque testing was also performed to determine insertion torque for the dental implants in Type III and Type IV bone.
## Sterilization Validation
The subject implants are sterilized by ℃o gamma irradiation at a nominal dose of 25 kGy (2.5 Mrad). Sterilization has been validated by the VDma22 method, according to ISO 11137-1 and ISO 11137-2. The method achieved a Sterility Assurance Level 10-6.
The Subject devices are not represented to be "pyrogen free". Routine endotoxin testing for NeoPoros and Acqua implants are performed monthly on representative samples of this group of products. The test limit is 20 EU/device as recommended by USP <161>.
The sterilization method presented for the subject devices is the same as for the predicate devices and has been previously reviewed under K163194 and K180536.
## Shelf Life Validation
The subject implants have a shelf life of 5 years that was validated by accelerated aging according to ASTM F1980. The packaging was validated according to ISO 11607-1 and ISTA 2A. Sealing strength (ASTM F88), Dye Penetration (ASTM F1929), and Bubble Test (ASTM F2096) were conducted to verify the maintenance of the sterile barrier after storage.
## CONCLUSION
The subject devices and the primary predicate devices K163194 have the same intended use, same design and technological characteristics, similar range of length, same sterilization method and are made of the same materials. The subject devices present a diameter that is contained within the range of diameters of the reference predicate devices. The data included in this submission demonstrate that the subject devices are substantially equivalent to the predicate devices.
