EQUIVALENCE TO MARKETED DEVICES
The subject device is substantially equivalent in indications and design principles to the primary predicate device and the reference devices listed above. The subject device, the primary predicate device, and the reference devices all are intended to provide functional and esthetic rehabilitation of the edentulous maxilla and mandible. Provided at the end of this summary are tables comparing the Indications for Use Statements (IFUS) and the technological characteristics of the subject device, the primary predicate device, and the reference devices.
The IFUS for the subject device combines language from the IFUS for the primary predicate device K220200 and, the reference device K112795,. All include language regarding surgical and restorative applications for placement in the bone of the upper or lower jaw to provide support for prosthetic devices to restore the patient's chewing function. The IFUS for the primary predicate K220200 also includes language regarding immediate loading, narrow implants, and Conical Implants. Similarly, the IFUS for the reference device K112795 (Internal Hex Implants) includes language regarding immediate loading. The subject device IFUS also includes details of the subject implant connections, platforms, body diameters and lengths; these details are not included in the IFUS for the primary predicate device (K220200) or the reference devices (K112795).
The IFUS of the reference devices K223814, K101545, and K170131 are all similar to that of the subject device in terms of the intended use to provide functional and esthetic rehabilitation of the edentulous maxilla and mandible, and all include language regarding immediate loading with good primary stability and with appropriate occlusal loading. The IFUS for K223814 includes language about validated milling centers and milled superstructures that is not applicable to the subject device.
None of the minor differences among the IFUS for the subject device, the primary predicate device, and the reference devices impact substantial equivalence because all IFUS express equivalent intended use to facilitate dental prosthetic restorations, and the indications are expressed equivalently using different specific wording.

§ 872.3640 Endosseous dental implant.
(a)
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.(b)
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.
