Intended Use

The Ni2 Implant System is indicated for surgical placement in the upper and lower jaw arches, to provide a root form means for single or multiple units' prosthetic attachment to restore a patient's chewing function. The smaller Ni2 dental implants (Ø3.6, 4.0, 5.0 mm) can be placed with a conventional two stage surgical process with an option for transmucosal healing or they can be placed in a single stage surgical process for immediate loading when good primary stability is achieved with appropriate occlusal loading. The larger Ni2 Implants (Ø6.0, 7.0 mm) can be placed with a conventional two stage surgical process with an option for transmucosal healing and are indicated for the molar region with delayed loading.

Device Story

Ni2 Implant System consists of endosseous dental implants, superstructures, and surgical/prosthetic instruments. Implants are screw-type, fabricated from Grade 4 CP titanium (ASTM F67) with S.L.A. (sand-blasted, large-grit, acid-etched) surface treatment. Used by dental surgeons in clinical settings for partially or fully edentulous patients. Implants are surgically inserted into the jawbone to serve as artificial tooth roots. Abutments connect to implants via a tapered conical hex joint to support crowns, bridges, or overdentures. System supports both one-stage and two-stage surgical protocols. Output is a stable foundation for prosthetic restoration, enabling chewing function recovery. Device is supplied sterile via gamma radiation.

Clinical Evidence

No clinical studies are submitted. Substantial equivalence is supported by non-clinical bench testing, including biocompatibility (ISO 10993-1), sterilization validation (ISO 11137), and MRI safety assessment.

Technological Characteristics

Material: CP Titanium Grade 4 (ASTM F67). Surface: S.L.A. (Sand-blasted, large-grit, acid-etched). Connection: Tapered conical hex. Sterilization: Gamma radiation. Shelf life: 8 years. Form factor: Screw-type endosseous implant.

Indications for Use

Indicated for patients requiring single or multiple unit prosthetic restoration in the upper or lower jaw arches. Smaller implants (Ø3.6-5.0mm) suitable for immediate or delayed loading; larger implants (Ø6.0-7.0mm) indicated for molar region with 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.

The Ni2 Implant System is specially designed for use in dental implant surgery. A successfully osseointegrated implant will achieve a firm implant when surgically implanted under controlled conditions. They are intended for use in partially or fully edentulous mandibles and maxillae, in support of single or multiple unit restorations. The Ni2 Implant System, fixtures are made of commercial pure titanium, grade 4 (ASTM F67) which have a S.L.A (Sand blasted large grit acid etched) treated surface and supplied sterile (gamma radiation). These fixtures can be used one stage surgery method or two stage surgery method. And that are surgically inserted into the upper and/or lower jawbone. The fixtures replace tooth root as providing a stable foundation for restorations. Geometrically, the implant is screw type. An abutment is connected to the implant through a tapered joint. The Ni2 fixtures are compatible with the abutments which have been previously cleared in K221866. The non-threaded section of the implant body is also SLA surface treated. #### Substantial Equivalent Comparison Chart Image /page/5/Figure/8 description: The image shows a diagram of a screw with three dimensions labeled.

General Indications: Both the subject device and the predicate device share similar overarching indications for use. They are both designed for surgical placement in the upper and lower jaw arches, with the primary goal of providing a root form means for prosthetic attachment to restore a patient's chewing function. - 2. Implant Sizes and Surgical Procedures: Both systems offer a range of implant sizes to accommodate various clinical scenarios. The smaller implants of both systems (03.6~ 05.2 mm) can be placed using a conventional two stage surgical process, with the option for transmucosal healing. Additionally, both systems provide the flexibility of a single-stage surgical process for immediate loading when there is good primary stability, with appropriate occlusal loading. The non-threaded section of the implant body is also SLA surface treated. - 3. Molar Region and Delayed Loading: The larger implants in both systems (Ø6.0 ~ Ø7.0 mm) are specifically indicated for the molar region and involve a conventional two-stage surgical process with an option for transmucosal healing, accompanied by delayed loading. This demonstrates a parallel approach to addressing the unique requirements of the molar region. Discussion: The comparisons highlight the substantial equivalence between the subject and the predicate device. The similarities in their indications for use, design, implant sizes, and surgical procedures demonstrate that the differences do not impact substantial equivalence. The minor variations in implant dimensions and specific procedural details are well within the acceptable range for dental implant systems, considering the diverse clinical needs and preferences of practitioners. Both systems provide suitable options for immediate loading and delayed loading based on clinical conditions, indicating flexibility in accommodating various patient cases. The Ni2 Implant System is similar to the predicate device (K221866) in terms of its design, dimensions, material, surface treatment, intended use, and technological characteristics. The subject device also includes diameters (3.6, 4.0, 5.0mm) that are not covered by the predicate device, but they fall within the range between the diameter of the reference devices (K122519 and K210852) and the diameter of the predicate device. Specifically, K210852 was included as a reference device to support the design of the 2mm of unthreaded SLA surface treated bone level implant body length implanted into the bone as the 2mm of unthreaded SLA surface treated of the subject device falls into the range of the reference device, K210852, which is between 0.7mm ~ 3.5mm. # Non-Clinical Test Data The non-clinical test data submitted for the Ni2 implant system validates its substantial equivalence to the predicate device. The outcomes collectively support the substantial equivalence of the Ni2 Implant System to the predicate device. - . The subject device will not be labeled as "non-pyrogenic". Bacterial Endotoxin Testing (LAL) in accordance with USP<85> and USP<161> in K221866. - .
