Device Story

J2I Implant System consists of threaded, root-form endosseous dental implants; manufactured from Titanium 6Al 4V ELI alloy; surface treated with Resorbable Blast Media (RBM). Implants are surgically placed into the mandible or maxilla by dental professionals; intended for single or two-stage surgical procedures with delayed loading. System supports single or multiple-unit restorations, including cemented, screw-retained, or overdenture prosthetics, and serves as terminal or intermediate abutment for fixed bridgework. Device provides structural foundation for tooth replacement; clinical benefit includes restoration of oral function and aesthetics for edentulous patients.

Clinical Evidence

Bench testing only. Includes sterilization validation (ISO 11137, ISO 17665), shelf-life validation via accelerated testing, and chemical/SEM analysis to verify absence of RBM treatment residuals.

Technological Characteristics

Material: Titanium 6Al 4V ELI (ASTM F136). Design: Threaded, root-form, bone-level implant with internal octagon abutment connection. Surface: RBM (Resorbable Blast Media) treated. Sterilization: Gamma and steam sterilization. Dimensions: Platform diameters 4.8mm/6.5mm/10.0mm; fixture diameters 4.1mm-4.8mm; lengths 8.0mm-13.0mm.

Indications for Use

Indicated for partially or fully edentulous adult patients requiring single or multiple-unit dental restorations, including cemented, screw-retained, or overdenture restorations, and fixed bridgework support in mandibles and maxillae.

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. Description:

The J2I Implant System is a dental implant system made of Titanium 6AL 4V ELI alloy intended to be surgically placed in the bone of the upper or lower jaw arches for loading after a conventional healing period. The implant may be used to replace one or more missing teeth. The system is similar to other commercially available products based on the intended use, the technology used, the claims, the material composition employed and performance characteristics. The surface of the system has been treated with R.B.M (Resorbable Blast Media).

### 6. Indication for use:

J2I Implant System is indicated for use in partially or fully edentulous mandibles and maxillae, in support of single or multiple-unit restorations including; cemented retained, screw retained, or overdenture restorations, and terminal or intermediate abutment support for fixed bridgework. J2I Implant System is for single and two stage surgical procedures. It is intended for delayed loading.

#### Basis for Substantial Equivalence 7.

#### Similarities

J2I Implant System has the same intended use as the identified predicate device (K062051). J2I Implant System and SS FIXTURE SYSTEM are similar in fundamental scientific technology in that they are all threaded, root form implants constructed of titanium with RBM roughened surfaces. They all share same internal octagon abutment connection system with internal beveled interface for maximum prosthetic stability. The subject and predicate devices are both bone-level implants that share similar body shape design such as straight walled neck and tapered body design.

## Difference

The difference is in the body shape: cutting edge design and taper angle. However they are only the minor design factors, so they do not raise new questions on safety and effectiveness of the subject device.

### 8. Non-Clinical Testing

- . Sterilization validating testing has been performed in accordance with ISO 11137, ISO 11737-1 & ISO 11737-2 for gamma sterilization and ISO 17665-1 and ISO 17665-2 for steam sterilization.
- I Three year of shelf life has been validated through accelerating testing.
- Chemical and SEM image analyses have been performed to verify that there is no residual after RBM treatment on the fixtures.

### 9. Conclusion

The subject devices and the predicate devices have intended use and have the same technological characteristics. The subject and predicate implants are all made of commercially pure titanium and have the same surface treatments.

Overall, the J2I Implant System has the following similarities to the predicate devices:

- * has the same intended use,
- * uses the same operating principle,
- * incorporates the same basic design,
- * incorporates the same material and the surface treatment.

Based on the similarities, we conclude that the J2I Implant System is substantially equivalent to the predicate device.
