Intended Use

The Leone orthodontic mini implant is an implant device providing a fixed anchorage for attachment of orthodontic appliances to facilitate the orthodontic movement of the teeth. It is used temporarily in the maxillary and mandibular bone and must be removed after orthodontic treatment has been completed.

Device Story

Leone orthodontic mini implant is a one-piece endosseous screw; features right-hand thread endosseous portion and smooth tapered neck. Used by orthodontists in clinical settings to provide fixed anchorage for orthodontic appliances; facilitates tooth movement. Implant is placed temporarily in maxillary or mandibular bone; removed upon completion of orthodontic treatment. Device provides stable anchor point for appliances; benefits patient by enabling controlled tooth movement. Device is non-sterile; requires steam autoclave sterilization before use.

Clinical Evidence

No clinical data. Substantial equivalence is based on bench testing and comparison of technological characteristics.

Technological Characteristics

Material: Surgical stainless steel (ISO 5832-1). Design: One-piece endosseous screw with right-hand thread and smooth tapered neck. Available in various diameters, lengths, and head shapes. Sterilization: Non-sterile; steam autoclave required. Regulatory class: II.

Indications for Use

Indicated for patients requiring fixed orthodontic anchorage to facilitate tooth movement. Used temporarily in maxillary and mandibular bone; must be removed post-treatment.

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:

According to the similarities specified in the above comparison table between the current device Leone orthodontic mini implant and the predicate device, in indications for use, technology and performance specifications as supported by the results of the testing performed we conclude that the Leone orthodontic mini implant is substantially equivalent to the Dentos AbsoAnchor orthodontic microimplant, device currently marketed in USA under the Federal Food, Drug and Cosmetic Act.

The Leone orthodontic mini implant 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 orthodontic mini implant.
