Zimmer® One-Piece 3.7mm implants are indicated for the support and retention of fixed single tooth and fixed partial denture restorations in the premolar, cuspid, and incisor regions of partially edentulous jaws. Zimmer® One-Piece 3.7mm implants may be loaded immediately in the anterior mandibular arch if four are splinted together with a bar. The Zimmer® 3.7mm One-Piece implant may be immediately restored with a temporary prosthesis that is not in functional occlusion.
Zimmer® One-Piece 3.0mm implants are indicated for the support and retention of fixed single tooth and fixed partial denture restorations in the mandibular central and lateral incisor and maxillary lateral incisor regions of partially edentulous jaws. The Zimmer® One-Piece 3.0mm implant must be splinted if two or more are used adjacent to each other. The Zimmer® One-Piece 3.0mm implant may be immediately restored with a temporary prosthesis that is not in functional occlusion.
The Zimmer® Dental One-Piece Implant is a one-piece endosseous dental implant which is a combination of implant and abutment sections. The implant is composed of titanium alloy. The abutment portion is pre-prepared and contoured for esthetic restoration. The abutment portion of the implant features a pre-prepared margin to facilitate the restoration process. The implant section is designed for ease of implantation and with greater surface area for osseointegration. The implant section surface is treated to facilitate osseointegration. In addition, the implant section is tapered with either double or triple-lead threads, depending upon the apical diameter
I am sorry, but the provided text does not contain information about the acceptance criteria or a study proving that the device meets those criteria. The document describes a 510(k) premarket notification for a dental implant system (Zimmer® One-Piece Implant System), detailing its classification, intended use, device description, and comparison to predicate devices, and confirmation of substantial equivalence by the FDA. There is no mention of specific performance metrics, acceptance criteria, or any associated studies with sample sizes, ground truth establishment, or expert involvement to demonstrate the device's performance against defined criteria.
§ 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.
