Indications for Use

The MiNi Internal Implant System is intended for two-stage surgical procedures in the following situations and with the following clinical protocols: - The intended use for the 3.0 mm diameter MiNi implant is limited to the replacement of maxillary lateral incisors and mandibular incisors. - Immediate placement in extraction sites and in situations with a partially or completely healed alveolar ridge. - It is intended for delayed loading.

Device Story

MiNi Internal Implant System consists of CP Ti Grade 4 endosseous dental fixtures, abutments, and surgical instruments. Used in two-stage dental implant surgery to provide screw or cement-retained restorations. Fixtures feature S.L.A. (Sand-blasted, Large grit, Acid-etched) surface treatment. System includes various abutments (e.g., healing, angled, milling, temporary, impression copings). Clinicians perform surgical placement in dental clinics. Output is a stable root-form foundation for prosthetic teeth, restoring chewing function and aesthetics for patients with missing teeth.

Clinical Evidence

Bench testing only. Fatigue testing performed per ISO 14801:2007. Sterilization validation performed per ISO 11137 and ISO 17665 series. Biocompatibility, surface analysis, and residue analysis were not conducted, relying on equivalence in material, surface treatment, and manufacturing processes to the reference predicate (K140091).

Technological Characteristics

Materials: CP Ti Grade 4 (ASTM F67). Surface: S.L.A. (Sand-blasted, Large grit, Acid-etched). Fixture diameters: 3.0mm, 3.4mm. Lengths: 8.0mm to 14.5mm. Connection: Internal Hex. Sterilization: Gamma and steam sterilization.

Indications for Use

Indicated for two-stage surgical procedures for replacement of maxillary lateral incisors and mandibular incisors (3.0 mm diameter implants). Suitable for immediate placement in extraction sites or healed alveolar ridges. Intended for delayed loading.

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.

{5}------------------------------------------------

{6}------------------------------------------------

The differences in indications between the MiNi Internal Implant System and primary predicate device (K120414) do not raise new questions of substantial equivalence because they are selected as a subset of the primary predicate. The MiNi Internal Implant System removed the indications of one-stage surgery, immediate loading, and soft bone clinical use compared to the primary predicate (K120414). Thus, the proposed indications do not increase risk nor change the intended use of the device and are found to be substantially equivalent.

## Non-Clinical Test Data

Sterilization validating testing has been performed in accordance with ISO 11137-1, ISO 11137-2,

{7}------------------------------------------------

ISO 11137-3, ISO 11737-1, and ISO 11737-2 for gamma sterilization and ISO 17665-1 and ISO 17665-2 for steam sterilization. Test results have demonstrated that the SAL of 10th was achieved and all testing requirements were met.

The fatigue test was performed on the subject device in accordance with ISO 14801:2007 Dentistry-Implants-Dynamic fatigue test for endosseous dental implants. The worst case scenario was chosen based on the FDA guidance "Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Implant Abutments".

The results of the non-clinical testing demonstrate that the results have met the criteria of the standards, and the subject device is substantially equivalent to the predicate device.

| Testing Item | |
|---------------------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| Conducted test<br>on the subject device | Fatigue Test<br>Sterility test |
| Not conducted test<br>on the subject device | Biocompatibility test:<br>Cytotoxicity<br>Sensitization<br>Irritation or Intracutaneous reactivity<br>Systemic toxicity<br>Sub-chronic Toxicity<br>Genotoxocity<br>Implantation<br>Surface Analysis<br>Residue Analysis |

Biocompatibility Test, surface analysis, and residue analysis have not been conducted because the subject device has the same material, surface treatment, and manufacturing process as the reference predicate device (K140091). There is no difference between the subject and predicate device. There is no additional testing conducted on the subject device.

#### Conclusions

In accordance with the Federal Food, Drug and Cosmetic Act, 21 CFR Part 807, and based on the information provided in this premarket notification, Megagen Implant Co., Ltd. concludes that the MiNi Internal Implant system is substantially equivalent to predicate devices as described herein.
