Intended Use

The Neoss ProActive Implant is for single-stage and two-stage surgical procedures and cement or screw retained restorations. The Neoss ProActive Implant is intended for immediate placement and function on single tooth and /or multiple tooth applications recognizing sufficient bone stability and appropriate occlusal loading, to restore chewing function. Multiple tooth applications may be splinted with a bar.

Device Story

Neoss ProActive Implant is a root-form titanium dental implant with internal abutment connection; threaded design. Used in single-stage or two-stage surgical procedures for cement or screw-retained restorations. Implant diameters range from 3.5 to 5.5 mm; lengths from 7.0 to 19.0 mm. Device features grit-blasted and acid-etched surface finish to enhance osseointegration strength and bone-to-implant contact. Operated by dental surgeons in clinical settings. Output is a stable foundation for prosthetic restoration to restore chewing function. Benefits include improved osseointegration compared to machined surfaces.

Clinical Evidence

No clinical data. Evidence consists of non-clinical animal testing comparing grit-blasted and acid-etched surfaces to machined surfaces, demonstrating increased osseointegration strength and bone-to-implant contact.

Technological Characteristics

Titanium root-form dental implant; threaded design with internal abutment connection. Surface finish: grit-blasted and acid-etched. Dimensions: 3.5-5.5 mm diameter, 7.0-19.0 mm length. Supplied sterile.

Indications for Use

Indicated for patients requiring single or multiple tooth replacement via single-stage or two-stage surgical procedures, including immediate placement and function, provided there is sufficient bone stability and appropriate occlusal 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.

### Device Description:

The Neoss ProActive is an modified version of the Neoss Bimodal Implant (K043195), Identical to K043195, the ProActive Implant is a threaded, internal abutment connection, root-form titanium dental implant. The ProActive assortment consists of a number of implants with a diameter of Ø3,5 to Ø5,5 mm and lengths between 7,0 - 19.0 mm having the same internal abutment dimension independent of implant diameter. The internal connection being equipped with interlocking elements for an insertion tool and the non-rotational locking of the abutment. Supplied sterile.

#### Indication for Use: as per K043195, as cleared for Neoss Bimodal Implant

The Neoss ProActive Implant is for single-stage and two-stage surgical procedures and cement or screw retained restorations.

The Neoss ProActive Implant are intended for immediate placement and function on single tooth and /or multiple tooth applications recognizing sufficient bone stability and appropriate occlusal loading, to restore chewing function. Multiple tooth applications may be splinted with a bar.

#### Summary of Technological Characteristics:

The modification to the Neoss Bimodal Implant since its previous clearance in K043195 is a change to the surface finish process only. The modifications are changes required to improve device performance. In animal testing, grit-blasted and acid-etched surfaces exhibit an increase in the strength of osseointegration when compared to machined surfaces. Additionally, in animal testing, grit-blasted and acid-etched surfaces exhibit an increased

bone to implant contact when compared to grit-blasted surfaces. These minor differences do not affect the safety or performance of the device and do not change the intended use of the ProActive Implant when compared to the Neoss Bimodal Implant.

### Summary of Nonclinical Testing:

Based on the Risk Analysis, performance testing was conducted to confirm compliance to device specifications; all functions were verified to operate as designed.

### Substantial Equivalence Discussion:

The change to the surface finish process of the Neoss ProActive Implant does not change the intended use nor do they affect the safety and effectiveness as compared to the Neoss Bimodal Implant previously cleared in K043195.

#### Conclusion:

The modified Neoss ProActive Implant has the following similarities to the Neoss Bimodal Implant previously cleared in K043195:

- . has the same indicated use,
- uses the same operating principle, .
- . incorporates the same basic device design and physical properties,
- . incorporates the same materials.

Therefore the modification to the Neoss ProActive Implant can be found substantially equivalent to the Neoss Bimodal Implant.
