Surgically inserted by dental professionals into the mandible between the two foramina. Acts as anchorage system for total removable prosthesis; requires four implants for support. Benefits patient by stabilizing removable dentures.

Clinical Evidence

No clinical data; bench testing only.

Technological Characteristics

Titanium alloy; one-piece endosseous screw design; sandblasted surface; sterile; non-networked; mechanical anchorage system.

Indications for Use

Indicated for stabilization of removable prosthesis on lower arch in patients with total lower edentulism. Requires surgical insertion of four implants into the mandible between the two foramina.

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.

## Description of the device:

The Leone Monoimplant for O-ring overdenture is a one-piece endosseous dental implant where an endosseous portion and an abutment portion are defined. The implant is composed of titanium alloy for surgical use. The endosseous portion is a self-tapping screw with a sandblasted surface, while the abutment portion is made of a smooth tapered neck favouring soft tissues healing and mucosal seal and a ball shape top for the connection to the overdenture's microhousing. The monoimplant is supplied in different sizes and is intended for use in the overdenture O-ring therapy in the treatment of the total lower edentulism.

Intended use:

Summary of the technological characteristics of our device compared to the redicato davings:

## Conclusion:

The Leone Monoimplant for O-ring overdenture intended use is equivalent to the IMTEC Sendax MDI and MDI Plus long-term application and to the Leone Implant System anchorage for removable prosthesis in case of the stabilization of an overdenture. The Leone Monoimplant for O-ring overdenture and the predicate devices are composed of the same biocompatible titanium alloy for surgical use, they are substantially equivalent in design, physical characteristics, functional performance, labelling, potential adverse effects. Based on the information provided herein, we conclude that the Leone Monoimplant for O-ring overdenture is substantially equivalent to the devices currently marketed under the Federal Food, Drug and Cosmetic Act. The Leone Monoimplant for O-ring overdenture raises no new issues of safety or effectiveness. Therefore, safety and effectiveness are reasonably assured, and substantial equivalence is supported, justifying 510(k) clearance of the Leone Monoimplant for O-ring overdenture.
