Intended Use

The NaturaLLock implant system is an endosseous dental implant system made of titanium. NaturaLLock implants are indicated for the support and retention of fixed single tooth and fixed partial denture restorations in the molar, premolar, cuspid, and incisor regions of partially edentulous jaws. NaturaLLock implants may be loaded immediately in the anterior mandibular arch if four are splinted together with a bar. NaturaLLock implants may be immediately restored with a temporary prosthesis that is not in functional occlusion.

Device Story

One-piece endosseous dental implant system; integrates implant and abutment sections. Features self-tapping thread; tapered body; axially directed grooves on implant head. Used in dental practices by qualified oral/maxillofacial surgeons or implantologists. Implants surgically placed in jaw bone to support prosthetic restorations. System includes surgical instruments, drills, and drill guide sleeves. Provides stable foundation for fixed single or partial dentures; allows immediate loading in anterior mandibular arch if splinted with bar; supports immediate temporary non-functional restoration. Benefits patient by restoring chewing function and aesthetics.

Clinical Evidence

Bench testing only. No clinical data provided. Testing included biocompatibility (ISO 10993), cleanliness, cytotoxicity, sterilization, and packaging validation. Performance testing confirmed compliance with acceptance criteria and equivalence to predicate devices.

Technological Characteristics

Material: Titanium. Design: One-piece endosseous implant with integrated abutment. Features: Tapered body, self-tapping thread, axially directed grooves. Sizes: Diameters 3.5mm to 6.0mm; lengths 8mm to 16mm. Sterilization: Implants provided sterile; instruments non-sterile (autoclavable).

Indications for Use

Indicated for support and retention of fixed single tooth and fixed partial denture restorations in molar, premolar, cuspid, and incisor regions of partially edentulous jaws. Contraindicated in patients with inadequate bone quality/width/height, systemic health issues (e.g., diabetes, smokers), or allergies to implant components.

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).

#### Description of the device:

The NaturaLLock single-stage implant for immediate restoration combines the endosteal and prosthetic implant sections in one piece (integrated abutment). The anatomically shaped implant has a self-tapping thread.

The NaturaLLock implant system includes single-stage implants, dental tools, instruments, drills, drill guide sleeves and a surgical tray, which contains a complete set of instruments structured according to the logical sequences of surgery.

The system is colour coded as follows: red Ø 3.5 mm, yellow Ø 4.3 mm, blue Ø 5.0 mm, green Ø 6.0 mm. The instruments are laser marked with the following information: drills: Ø and length, implant driver: Ø

#### Indication range:

For single and multiple tooth replacement in the upper and lower jaw. Adequate bone quality, width and height must be available. It has to be proven carefully, if the systemic state of the patient is adequate for an implantation, and especially if there are any allergic reactions on the implant components as well as any prohibitive diseases (e.g. diabetes, smoker).

#### Indications for Use:

The NaturaLLock implant system is an endosseous dental implant system made of titanium. NaturaLLock implants are indicated for the support and retention of fixed single tooth and fixed partial denture restorations in the molar, cuspid, and incisor regions of partially edentulous jaws. NaturaLLock implants may be loaded immediately in the anterior mandibular arch if four are splinted together with a bar. NaturaLLock implants may be immediately restored with a temporary prosthesis that is not in functional occlusion.

#### Comparison with predicate devices:

The ZL Microdent product is similiar to the predicate devices in terms of technical characteristics, design, indications for use, target population, where it is used, performance, biocompatibility characteristics as well as sizes, surfaces and configurations. Similar as the Nobel and Zimmer predicate devices the ZL Microdent NaturaLLock implants are one-piece constructions, have an integral, pre-contoured abutment, a tapered implant body, a self-cutting thread and an implant head with symmetrical, axially directed grooves.

{9}------------------------------------------------

Conclusion: The ZL Microdent product can be deemed substantially equivalent for its indicated use.

#### Summary of the non-clinical testing data:

Results of risk analysis, case studies, cleanliness testing, biocompatibility, sterilization, cytotoxicity and packaging testing have demonstrated that ZL Microdent NaturaLLock implants are equivalent to the predicate device implants tested. When compared with predicate devices, results of bench performance testing indicated all acceptance criteria were met, and demonstrated the subject implants are equivalent. A series of safety and performance testing were performed to demonstrate that the ZL Microdent NaturaLLock implants do not raise any new issues of safety and efficacy.

#### Summary:

The presented data that was conducted on the ZL Microdent products, shows in its results and in comparison to the predicate devices substantially equivalence to the predicate devices for their intended use. The used materials are well researched.
