Intended 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. The Neodent GM Helix LG implants can be placed bicortically in cases of reduced bone density. The Neodent GM Helix LG implants are only indicated for multiple unit restorations in splinted applications that utilize at least two implants.

Device Story

Neodent Implant System consists of endosseous dental implants (GM Helix LG) designed for surgical placement in upper or lower jaw bone. Implants provide support for prosthetic devices (artificial teeth) to restore chewing function. Device features include conical body, trapezoidal threads, and Grand Morse prosthetic interface. Used by dental surgeons in clinical settings. Implants are single-use, provided sterile. Clinical benefit includes restoration of chewing function and esthetics. Output is the physical implant acting as an anchor for prosthetic restorations. Decision-making relies on surgeon assessment of bone density and primary stability; bicortical placement is an option for reduced bone density cases.

Clinical Evidence

Bench testing only. Performance data includes dynamic fatigue testing per ISO 14801, static torsional loading, insertion torque testing in synthetic bone (types II, III, IV), and axial pull-out strength comparisons. Biocompatibility and biological safety assessments conducted per ISO 10993-1, 10993-5, 10993-12, and 10993-18. Sterilization validated per ISO 11137-2 to SAL 1x10^-6.

Technological Characteristics

Material: Commercially Pure Titanium Grade 4 (ASTM F67/ISO 5832-2). Design: Threaded root-form, conical apex, spherical tip, helical chambers, Grand Morse interface. Diameters: 3.75mm, 4.0mm. Lengths: 20mm, 22.5mm, 25mm. Surface: Acid-etched NeoPoros. Sterilization: Gamma irradiation (min 25 kGy, SAL 1x10^-6).

Indications for Use

Indicated for patients requiring dental restoration via endosseous implants in the upper or lower jaw. Suitable for single or multiple unit restorations, including immediate loading when primary stability is achieved. GM Helix LG implants are indicated for bicortical placement in reduced bone density and restricted to splinted, multiple-unit applications using at least two implants.

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.

## SUBSTANTIAL EQUIVALENCE DISCUSSION

The subject devices and the primary predicate device have equivalent intended use and Indications for Use statements. Both can be placed single or bicortically in mandible or maxilla. The subject devices and the primary predicate devices also share the same material of composition, the same sterilization method and range of length and present similar designs and platform diameter. The difference between the subject devices and the predicate devices is the Ø3.75 mm device. This change in technology is supported by the torsion test and pull out test, both included as appendices of this submission. The subject devices have the same thread design and the same implant-to-abutment interface design as the reference predicate devices.

## PERFORMANCE DATA

Dynamic fatigue test per ISO 14801 was performed to determine the fatigue strength for implant construct assembled with prosthetic abutment for multi-unit prosthesis, assembled with GM Helix LG Implants, according to FDA Guidance.

Torsion Test was performed to evaluate the GM Helix LG Implant under static torsional loading. Insertion test was performed to evaluate the insertion torque of the GM Helix LG Implant when inserted into sawbones material representing bone type II, III and IV.

Pull-out testing was performed to compare the Axial Pull-out Strength between the subject devices and the predicate devices.

Sterilization of the subject implants via gamma irradiation using a protocol of 25 kGy minimum dose has been performed according to the requirements established by ISO 11137-2. A minimum Sterility Assurance Level (SAL) of 1 x 10 ° has beenvalidated.

Biological Safety Assessment guided by ISO 10993-1, Cytotoxicity guided by ISO 10993-5 and Chemical characterization guided by ISO 10993-18 were performed for GM Helix LG implants. Biocompatibility sample preparation was performed per ISO 10993-12.

# CONCLUSION

The data included in this submission demonstrate that the subject devices are substantially equivalent to the predicate devices.
