Intended Use

The Neoss Tapered Implant is for single-stage or two-stage surgical procedure and cement or screw retained restorations. The Neoss Tapered 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 Tapered Implant is a threaded, root-form titanium dental implant; internal abutment connection. Designed for surgical placement into upper/lower jaw bone; provides permanent anchorage for prosthetic restorations (cement or screw-retained). Used by dental surgeons in clinical settings. Tapered geometry mimics natural tooth root; grit-blasted and acid-etched surface enhances osseointegration. Implant diameter 3.5–5.5 mm; length 7.0–17.0 mm. System includes compatible abutments and prosthetic components. Restores chewing function and aesthetics for patients with tooth loss. Clinical benefit derived from stable anchorage and osseointegration.

Clinical Evidence

No clinical data provided. Evidence consists of bench testing (fatigue testing) and animal studies comparing surface characteristics (grit-blasted/acid-etched vs. machined). Fatigue testing demonstrated performance consistent with predicate device requirements. Primary stability evaluated via in vitro insertion, displacement, and theoretical bone contact analysis.

Technological Characteristics

Titanium dental implant; threaded, root-form design with internal abutment connection. Surface treatment: grit-blasted and acid-etched. Dimensions: 3.5–5.5 mm diameter, 7.0–17.0 mm length. Supplied sterile. Abutment screws available in gold alloy, titanium, or Ti with TiN/Au coating (supplied non-sterile).

Indications for Use

Indicated for patients requiring dental restoration in upper or lower jaw arches via single or multiple tooth replacement. Suitable for 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 Tapered Implant is a threaded, internal abutment connection, root-form titanium dental implant. The Neoss Tapered Implant consists of a number of implants with a diameter of Ø3.5 to Ø5.5 mm and lengths between 7.0 – 17.0 mm; all sizes have the same internal abutment connection dimension independent of implant diameter.

The internal connection is equipped with interlocking elements for an insertion tool and the non-rotational locking of the abutment. The Neoss ProActive Tapered Implant System is intended for surgical placement into the bone of upper /lower jaw arches as a permanent anchorage for prosthetic devices, which can restore chewing function and aesthetic appearance. Supplied sterile.

The Neoss Implant System has specific design characteristics for mating Neoss components such as implants, abutments and prosthetic components. Combining components that are not configured or dimensioned for correct mating can lead to mechanical failure of components, damage to tissue, or unsatisfactory esthetic results. Abutment screws made in gold alloy, titanium or Ti with TiN/Au are available. Screw driver connection is compatible with screwdrivers supplied by Neoss. The abutment screws are supplied non-sterile.

#### Indication for Use:

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

The Neoss Tapered 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.

### Summary of Technological Characteristics:

The line extension to the Neoss ProActive Implant includes an assortment of tapered sizes. Tapered designs more closely reflect the shape of the tooth root. In animal testing, gritblasted 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.

#### Summary of Performance Testing:

Performed fatigue tests of ProActive implants (K083561) shows results well in line with requirements. Clinical feedback and only one fracture related complaint confirms that the implant strength is adequate. The design in critical areas shows enough similarity between the two implant types to conclude that Neoss Tapered Implants will show equivalent results as for ProActive Implants in a fatigue test.

The Neoss Tapered Implant has an enhanced primary stability, i.e. mechanical stability at time of insertion as measured by in vitro insertion, displacement, and theoretical implantbone contact analysis, compared to a straight Neoss implant. This testing of primary stability and long term clinical outcome has not been correlated.

#### Conclusion:

The modified Neoss Tapered Implant has the following similarities to the Neoss ProActive Implant previously cleared in K083561:

- uses the same operating principle,
- incorporates the same basic design, -
- incorporates the same materials,
- incorporates the same surface characteristics and -
- has similar packaging and is sterilized using the same materials and processes -

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