Intended Use

The S-Plant Dental 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 S-Plant Dental Implants (03.4, 3.6, 3.8, 4.2, 4.7, 5.2 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 S-Plant Dental Implants (06.0, 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. Dual abutments are intended for use with a dental implant to provide support for prosthetic restorations such as crowns, bridges, or overdentures. Healing abutments are used to make a natural soft tissue shape before setting and removing cover screw after osseointegration. Cover Screws are used to protect the internal portion of the implant, preventing soft tissue growth into the implant, facilitating provisional restorations when necessary, and enabling the transition to final restoration components once osseointegration is complete.

Device Story

S-Plant Dental Implant System consists of endosseous dental implants (fixtures), abutments, and cover screws. Fixtures are screw-type, made of Grade 4 CP titanium (ASTM F67) with S.L.A. surface treatment. Abutments and cover screws are made of Ti-6Al-4V ELI alloy (ASTM F136). System is used by dental surgeons in clinical settings to replace tooth roots in partially or fully edentulous patients. Fixtures are surgically placed in jawbone; abutments connect to fixtures via tapered conical hex joint to support crowns, bridges, or overdentures. Cover screws protect internal threads during healing. System supports both single-stage (immediate loading) and two-stage (delayed loading) surgical protocols. Benefits include restoration of chewing function and esthetics. Device is MR conditional based on scientific rationale and literature review.

Clinical Evidence

Bench testing only. Evidence includes biocompatibility testing (ISO 10993-1, 3, 5, 6, 10, 11, 12), sterilization validation (gamma radiation/moist heat), shelf-life testing (ASTM F1980), and surface characterization (EDS/SEM). MR conditional safety evaluated via scientific rationale and literature review.

Technological Characteristics

Endosseous dental implant system. Fixtures: Grade 4 CP titanium (ASTM F67), S.L.A. surface, screw-type, gamma-sterilized. Abutments/Screws: Ti-6Al-4V ELI alloy (ASTM F136), non-sterile (autoclave required). Connection: Tapered conical hex. Dimensions: Fixture diameters 3.4-7.0mm. No software or electronic components.

Indications for Use

Indicated for patients requiring single or multiple unit prosthetic restoration in the upper or lower jaw arches. Smaller implants (3.4-5.2mm) suitable for conventional two-stage or single-stage immediate loading. Larger implants (6.0-7.0mm) indicated for molar region with delayed loading.

#### Substantial Equivalence Discussion

#### 1. 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 (03.4 ~ Ø5.5 mm) can be placed using a conventional twostage 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.

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

- 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 S-Plant Dental Implant System and the DIO UF HSA Internal Sub-Merged Implant System. The similarities in their indications for use, implant sizes, and surgical procedures demonstrate that the differences between the two devices are not substantial enough to raise any safety or efficacy concerns.

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 S-Plant Dental Implant System is similar to the predicate device (K122519) in terms of its design, dimensions, material, surface treatment, intended use, and technological characteristics. The S-Plant Dental Implant System also includes diameters (3.4mm and 3.6mm) that are not covered by the predicate device, but they fall within the range between the diameter of the reference device (K161987) and the diameter of the predicate device. Therefore, upon comparing the subject device with both the predicate and reference devices, there have been no new substantial equivalence concerns identified for the S-Plant Dental Implant System in terms of safety and effectiveness.
