Indications for Use

The J2A Dental Implant System and J2C Dental Implant System are in partially or fully edentulous mandibles and maxillae, in support of single or multiple-unit restorations including; cemented retained, or overdenture restorations, and terminal or intermediate abutment support for fixed bridgework. The 12A Dental Implant System and J2C Dental Implant System are for single and two stage surgical procedures. These systems are intended for delayed loading.

Device Story

J2A and J2C Dental Implant Systems are internal hexagon dental implants; surgically placed in maxilla or mandible bone to replace missing teeth. Implants consist of titanium alloy fixtures and abutments; surface treated with Resorbable Blast Media (RBM) or TiN coating. Used by dental surgeons in clinical settings for single or two-stage procedures; intended for delayed loading. Output is a stable foundation for dental restorations; aids in restoring masticatory function and aesthetics for edentulous patients.

Clinical Evidence

Bench testing only. No clinical data provided. Substantial equivalence supported by risk analysis, biocompatibility, and performance testing of the predicate device (K121047).

Technological Characteristics

Materials: Ti 6Al 4V ELI (ASTM F136). Surface: RBM (fixtures), TiN coating (abutments). Design: Internal hexagon connection, bone-level, tapered body. Sterilization: Gamma. Connectivity: None (mechanical device).

Indications for Use

Indicated for partially or fully edentulous patients (mandibles and maxillae) requiring single or multiple-unit restorations (cemented, screw-retained, or overdenture) or terminal/intermediate abutment support for fixed bridgework. Suitable for single or two-stage surgical procedures with 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.

### 7. Basis for Substantial Equivalence

### 7.1. Fixtures and Cover Screws

The I2A Dental Implant and J2C Dental Implant have the identified predicate devices. They 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 hexagon abutment connection system with interface. The subject and predicate devices are both bone-level implants that share similar body shape design walled neck and tapered body design.

The manufacturing facility, raw materials for the surface treatments (RBA treatment), surface treatment method, manufacturing process, and cleaning process of the J2A and I2C Dental Implant are identical to the predicate device (Hero I and IS Dental Implant System, K121047).

### 8. Non-Clinical Testing

Risk analysis was conducted according to ISO14971 to demonstrate that the following modifications to the company's own predicate, Hero II Dental Implant System (K121047) is substantially equivalent:

- Fixture thread design change ●
- . Fixture size addition
- Coating area expansion for one-piece type abutments
- Abutment size addition .

Additional predicate devices of similar design and dimensions were identified to determine substantial equivalence. In addition, based on the risk analysis the shelf-life, sterilization, biocompatibility, and performance testing of the predicate, Hero II Dental Implant System (K121047), is applicable to the subject device.

## 9. Conclusion

The subject devices and the predicate device have the same 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 J2A Dental Implant system and the J2C Dental Implant system have the following similarities to the predicate device:

- * have the same intended use,
- * use the same operating principle,
- * incorporate the same basic design,
- * incorporate the same material and the surface treatment.

Based on the similarities, we conclude that the J2A Dental Implant system and the J2C Dental Implant system are substantially equivalent to the predicate devices.
