Intended Use

The Tapered Screw-Vent® X Implants are designed for use in the maxilla or mandible for immediate loading or for loading after a conventional healing period. Implants may be used to replace one or more missing teeth. Immediate loading is indicated when there is good primary stability and an appropriate occlusal load. The 4.1mmD Tapered Screw Vent X Implants should be splinted to additional implants when used in the posterior region.

Device Story

Endosseous dental implant; replaces missing teeth in maxilla or mandible. Features titanium alloy body with Trabecular Metal sleeve; tapered design with triple-lead threads; apical flutes for self-tapping. Implanted by dental professionals in clinical settings. Provides foundation for prosthetic restoration; osseointegration facilitated by MTX surface treatment. Immediate or delayed loading protocols supported. Benefits patient through restoration of dental function and aesthetics.

Clinical Evidence

Prospective clinical study evaluated performance in posterior region with 2-week immediate load protocol and 6-month endpoint. Longitudinal data collection study included patients with elevated risk factors (e.g., smokers, diabetics, bone graft patients). No device-related adverse events reported in either study.

Technological Characteristics

Material: Titanium 6Al-4V and Trabecular Metal (tantalum). Design: Tapered body, triple-lead threads, internal hex interface. Surface: MTX treatment. Dimensions: 4.1, 4.7, 6.0mm diameters; 8-13mm lengths. Connectivity: None. Sterilization: Not specified.

Indications for Use

Indicated for patients requiring replacement of one or more missing teeth in the maxilla or mandible. Suitable for immediate loading given good primary stability and appropriate occlusal load, or conventional healing periods. 4.1mm diameter implants require splinting when used in the posterior region.

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.

#### 4. Device Description:

The Tapered Screw-Vent®X Implant is an endosseous dental implant. The implant is composed of titanium alloy and Trabecular metal. The implant section is designed for ease of implantation and with greater surface area for osseointegration. The implant section surface is treated to facilitate osseointegration. In addition, the implant section is tapered with triple-lead threads.

The Tapered Screw-Vent X implants will be offered in two different texturing configurations: full texture to the top of the implant and texture to 0.5mm from the top of the implant. In addition, both texturing configurations of the implant will have coronal grooves on the collar to within 0.64mm of the top of the implant similar to the predicate Tapered Screw-Vent P Dental implant. The implant/abutment interface platform diameter will be offered in sizes of 3.5mm, 4.5mm, or 5.7mm depending on the outside implant thread diameter. The new device will feature MTX surface equivalent to existing Zimmer Dental implants. The MTX surface is used on the titanium body and is exposed on surfaces apical and coronal to the Trabecular Metal.

#### 5. Indications for_Use:

The Tapered Screw-Vent® X Implants are designed for use in the maxilla or mandible for immediate loading or for loading after a conventional healing period. Implants may be used to replace one or more missing teeth. Immediate loading is indicated when there is good primary stability and an appropriate occlusal load. The 4.1mmD Tapered Screw Vent X Implants should be splinted to additional implants when used in the posterior region.

#### 6. Device Comparison:

The Tapered Screw-Vent X implant is substantially equivalent to Zimmer's Tapered Screw-Vent P implant. Both implants have the same friction fit internal hexagon connection and use the same prosthetic components to restore the implant. Both implants feature triple lead threads that taper inwardly from the coronal to the apical end of the implant (the overall taper for both of the implants are 2 degrees). Both implants have apical flutes that allow the implant to self tap into the osteotomy. The threaded portion and the coronal end of the Tapered Screw-Vent X implant are nearly identical to the Tapered Screw-Vent P implant, having a slight increase of the macro-threads for the coronal and apical sections to provide an insertion torque performance similar to the current Tapered Screw-Vent implants. The Tapered Screw Vent X

#### 8. Non-clinical Testing

Testing was performed following "Guidance for Industry and FDA Staff -Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Abutments." Performance testing demonstrated that the device performs appropriately for the proposed indications for use.

#### ு. Clinical Testing

A prospective clinical study was conducted to evaluate the performance of this device within a controlled population that included implantation within the posterior reqion only and a two week final restoration immediate load protocol with a 6-month end point.

A second, longitudinal data collection study was initiated to gather data on the routine placement and functioning within normal clinical conditions. This population included normal patients and subjects with elevated risk factors that were excluded from the controlled study, such as: alcoholics, substance abusers, mentally unstable, smokers,

osteoporotics, uncontrolled diabetics, parafunctional habits, dental or oral infections, and bone graft patients.

No device related adverse events were reported in either study to date.

#### 10. Conclusion

ﺑ

Based on our analysis, the device is substantially equivalent to the predicates and it is considered that the new device is as safe and effective for its indications for use.
