Intended Use

The Leone Implant System is indicated for single or multiple tooth replacement, or for use in terminal or intermediate edentulous sites in the mandible and/or the maxilla, and for totally edentulous arches. The system is designed to be surgically inserted in the bone structure of the mouth in order to replace missing teeth. It can work as an abutment system for partial/total prosthetic restorations or as an anchorage system for removable prosthodontics.

Device Story

The Leone Implant System consists of a titanium fixture and abutment; components are joined via a self-locking tapered connection utilizing a Morse cone and hexagon. The device is surgically inserted into the mandibular or maxillary bone structure to replace missing teeth. It serves as an abutment for fixed bridges, partial dentures, or as an anchorage for removable prosthodontics. The system is used by dental professionals in a clinical setting to restore oral function and aesthetics for patients with tooth loss.

Clinical Evidence

No clinical data provided; substantial equivalence is based on technological characteristics and intended use comparisons.

Technological Characteristics

Titanium construction; self-locking tapered connection (Morse cone and hexagon); endosseous dental implant; intended for surgical insertion into bone.

Indications for Use

Indicated for single or multiple tooth replacement in edentulous sites of the mandible or maxilla, including totally edentulous arches, for patients requiring prosthetic restoration or removable prosthodontics.

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.

## Conclusion

Based on the Intended Use, Materials and Biocompatibility, and when it is used, the Leone Implant System is substantially equivalent to the devices currently marketed under the Federal Food, Drug and Cosmetic Act. The Leone Implant System 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 Implant System.
