Indications for Use

Z5-BL implants are designed for surgical implantation into the upper and lower jaw for the attachment of prosthodontic appliances to replace missing teeth. Z5-BL implants are suitable for patients with metal allergies and the chronic diseases resulting from them. Z5-BL implants are intended for delayed loading.

Device Story

Z5-BL is a root-form, endosseous threaded dental implant system for surgical placement in the maxilla or mandible. System includes 3.6 mm diameter implants (8 mm, 10 mm lengths), gingiva formers, and straight/15° angled abutments for single-unit cemented restorations. Compatible with previously cleared components (K190243) including healing caps, multi-unit abutments, and Locator-type abutments. Implants manufactured from Y-TZP zirconia (ISO 13356); abutments from Y-TZP or PEEK. Implants provided sterile (plasma gas); other components sterilized by end-user (moist heat). Used by dental clinicians for functional and esthetic rehabilitation of edentulous patients. Output is a stable base for prosthetic appliances; clinical decision-making involves surgical site preparation and delayed loading protocols. Benefits include metal-free alternative for patients with metal allergies.

Clinical Evidence

Bench testing only. No clinical data included. Testing included: sterilization validation (ISO 14937, ISO 17665-1), shelf life (ISO 11607, ASTM F1886, ASTM D3078), bacterial endotoxin (USP <85>), biocompatibility (ISO 10993, USP Class VI), static/dynamic compression fatigue (ISO 14801), abutment screw loosening/removal torque (ISO 18130), and wear particle analysis (SEM/EDX).

Technological Characteristics

Materials: Y-TZP zirconia (ISO 13356), PEEK. Design: Root-form, endosseous threaded, 3.6 mm diameter. Surface: Grit-blasted and laser modified. Sterilization: Plasma gas (implants), moist heat (abutments). Mechanical: Static/dynamic fatigue testing per ISO 14801. Connectivity: None.

Indications for Use

Indicated for patients requiring dental implants in the upper or lower jaw for prosthodontic appliance attachment to replace missing teeth, including patients with metal allergies and associated chronic diseases. Intended for delayed loading.

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.

No clinical data were included in this submission.

#### 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. Provided at the end of this summary is a table comparing the Indications for Use Statements and the technological characteristics of the subject device, the primary predicate device, and the reference devices.

The subject device is substantially equivalent in intended use to the primary predicate K190243, and to the reference devices K132881 and K131701. All are intended for use in the maxilla and mandible to provide functional and esthetic rehabilitation of the edentulous maxilla and mandible. The subject device and the primary predicate device K190243 are made of identical materials (implants and abutments). The subject device dental implants and the primary predicate device K190243 dental implants have an identical endosseous threaded surface (grit-blasted and laser modified), have the same internal implant connection features, and the same implant lengths. The subject device and the primary predicate device K190243 also include straight and angled abutments for cement-retained, single-unit restorations. Differences between subject device and the primary predicate device K190243 include the implant diameter (subject device 3.6 mm) and implant platform diameter (subject device also 3.6 mm). None of these minor design differences impact safety or effectiveness or change the intended use of the device.

The reference device K132881 is for support of substantial equivalence of the subject device in terms of sterilization and shelf life (also referenced in K190243). The subject device dental implants are provided to the end user sterilized by plasma gas. The subject device components that are provided sterile use the same packaging and have the same sterile barrier shelf life as the sterile components cleared in K132881 (referenced in K190243). The processes to monitor, control, and test for bacterial endotoxins for the subject device are the same as K190243.

The reference device K131701 is for support of substantial equivalence of the subject device in terms of the smaller dental implant body diameter and corresponding implant platform diameter (both 3.6 mm). The subject device dental implants and the reference device K131701 dental implants also are made of identical materials, and have the identical endosseous threaded surface (grit-blaster and laser modified).

Mechanical performance testing of the subject device was performed according to ISO 14801 Dentistry -Implants – Dynamic fatigue test for endosseous dental implants. The fatigue limit data demonstrated that constructs of the device have sufficient strength for their intended use.

Minor differences in the designs, dimensions, sizes, or materials among the subject device, the primary predicate device, and the reference devices do not affect substantial equivalence. These minor differences do not impact safety or effectiveness because these differences are related to the specific designs features and system components, and are mitigated by the mechanical performance testing.

{6}------------------------------------------------

#### CONCLUSION

The subject device, the primary predicate device, and the reference devices have the same intended use, have similar technological characteristics, and are made of identical materials. The subject device, the primary predicate, and reference devices encompass the same range of physical dimensions, are packaged in similar materials, and are sterilized using similar methods. The data included in this submission demonstrate substantial equivalence to the predicate devices listed above.
