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.
Device Story
One-piece endosseous dental implant; titanium alloy construction; combines implant and abutment sections. Abutment features 17-degree angle and pre-prepared margin for esthetic restoration. Implant section is tapered with double-lead threads and surface-treated for osseointegration. Used by dental professionals in clinical settings for tooth replacement. Provides structural support for fixed restorations; facilitates restoration process via pre-contoured abutment.
Clinical Evidence
Bench testing only.
Technological Characteristics
Titanium alloy; one-piece design; 17-degree angled abutment; tapered implant body with double-lead threads; surface-treated for osseointegration.
Indications for Use
Indicated for support and retention of fixed single tooth and fixed partial denture restorations in premolar, cuspid, and incisor regions of partially edentulous jaws. May be loaded immediately in anterior mandibular arch if four are splinted with a bar; may be restored with temporary prosthesis not in functional occlusion.
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.
