Intended Use

The Legacy Dental Implant with HA coating is a dental implant fixture that is a part of a two-piece implant system. The Legacy implants are intended for use in the mandible and maxilla, in support of single or multiple-unit cement or screw receiving fixed restorations and for retention and support of overdentures. The implants are intended for immediate placement and function for support of single tooth and/or multiple tooth restorations, recognizing bone stability and appropriate occlusal load requirements.

Device Story

Legacy System Dental Implants are two-piece endosseous dental implants; used in mandible and maxilla for single or multiple-unit fixed restorations or overdentures. Implants feature tapered screw-type design; standard 'V' thread configuration; 2mm mini-threads at coronal aspect. Manufactured from medical-grade titanium alloy; surface treated with hydroxyapatite (HA) plasma spray. Device implanted by dental professionals during single or two-stage surgical procedures. Provides structural support for prosthetic restorations; enables immediate placement and function based on bone stability and occlusal load assessment.

Clinical Evidence

No clinical data provided; substantial equivalence is based on technological characteristics and intended use comparison to predicate devices.

Technological Characteristics

Endosseous dental implant; two-piece system. Material: medical-grade titanium alloy. Surface treatment: HA plasma sprayed. Design: tapered screw-type, standard 'V' thread, 2mm mini-threads at coronal aspect. Non-electronic, mechanical device.

Indications for Use

Indicated for patients requiring dental restoration in the mandible or maxilla. Supports single or multiple-unit cement or screw-retained fixed restorations and overdentures. Suitable for immediate placement and function, contingent upon bone stability and occlusal load requirements.

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.
