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 (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.
Dual abutments are intended for use with a dental implant to prosthetic restorations such as crowns, bridges, or overdentures. Healing abutments are used to make a natural soft tissue shape before setting up prosthetics 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.
The S-Plant Dental Implant System is comprised of dental implants, superstructures, instruments for prosthetics and surgical instruments. The S-Plant Dental 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 S-Plant Dental 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 roots providing a stable foundation for restorations. Geometrically, the implant is screw tvpe. An abutment is connected to the implant through a tapered joint.
The Abutment made of Ti-6AL-4V ELI alloy (ASTM F136) is intended for use as an aid in single or multiple-unit prosthetic restorations. It consists of Healing Abutment, Dual Abutment, and Abutment Screws. All abutments are supplied non-sterile and autoclaved by the end user.
The Cover Screw made of Ti-6Al-4V ELI alloy (ASTM F136), is an essential component in dental implant procedures. This device safeguards the internal threads of dental implant fixtures during the healing phase, ensuring a sterile environment for successful osseointegration.
The provided text describes the regulatory clearance of the S-Plant Dental Implant System and its components (Fixture, Dual Abutment, Healing Abutment, Abutment Screw, Cover Screw) by demonstrating substantial equivalence to predicate and reference devices. The acceptance criteria and the study that proves the device meets these criteria are primarily based on non-clinical testing and comparison with existing, legally marketed devices.
Here's a breakdown of the requested information:
1. Table of Acceptance Criteria and Reported Device Performance
The acceptance criteria are implicitly defined by the FDA's "substantial equivalence" framework, meaning the device must perform as safely and effectively as legally marketed predicate devices without raising new questions of safety or effectiveness. The reported device performance is demonstrated by comparing its design, materials, intended use, and technological characteristics to the predicate and reference devices, and by non-clinical testing that meets established industry standards.
| Acceptance Criteria Category | Specific Criteria (Implicitly based on Substantial Equivalence and Standards) | Reported Device Performance |
|---|---|---|
| Intended Use | The device's intended use should be substantially equivalent to that of predicate devices, aiming for functional and aesthetic rehabilitation through prosthetic attachment in the upper and lower jaw arches to restore chewing function. | Fixture: "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." This is directly compared to and found to be substantially equivalent to the predicate device (DIO UF HSA Internal Sub-merged Implant System, K122519) and reference device (DIO UF(II) Narrow Implant System, K161987).Abutments (Dual, Healing): "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 up prosthetics and removing cover screw after osseointegration." These are found to be substantially equivalent to their respective reference devices.Cover Screw: "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." This is found to be substantially equivalent to its reference device.Abutment Screw: "Abutment Screw is used to connect an abutment to the fixture." This is found to be substantially equivalent to its reference device. |
| Materials | Device materials should be biocompatible and consistent with established standards for dental implants and their components (e.g., CP Ti Grade 4, Ti-6Al-4V ELI alloy). | Fixture: "commercial pure titanium, grade 4 (ASTM F67)". Compared to predicate/reference devices also using CP Ti Grade 4 (ASTM F67).Abutment (Dual/Healing), Abutment Screw, Cover Screw: "Ti-6AL-4V ELI alloy (ASTM F136)". Compared to reference devices also using Titanium Alloy (Ti-6Al-4V, ASTM F136) or Pure Titanium Grade 4 (ASTM F67) for healing abutment. Demonstrated biocompatibility through ISO 7405, ISO 10993-1, -3, -5, -6, -10, -11, -12 testing. |
| Design and Dimensions | The device's design (e.g., screw type, tapered conical hex connection, surface treatment) and range of dimensions should be comparable to predicate devices. Minor variations should not raise new safety or effectiveness concerns. | Fixture: "Geometrically, the implant is screw type. An abutment is connected to the implant through a tapered joint." "S.L.A (Sand blasted large grit acid etched) treated surface." Dimensions are provided in a detailed table and compared to predicate/reference devices; "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." Found substantially equivalent.Abutments, Screws, Cover Screw: Designs are shown via images (text states "Image: Subject Device Design") and dimensions are provided/compared in tables, demonstrating substantial equivalence. For Abutment Screw, explicit mention that "Although the diameter and length of the screws differ slightly, the gap range is minimal, measuring less than 1-1.5mm. Consequently, this variance does not give rise to any concerns about the safety and effectiveness..."Surface modification confirmed via EDS and SEM evaluations. |
| Sterilization | The device should be sterilized according to validated methods and have an appropriate shelf life. | Fixture: "supplied sterile (gamma radiation)." Sterilization validation included gamma radiation and gravity displacement moist heat, per ISO 11137-1, ISO 11137-2, ANSI/AAMI ST79. Shelf life of 8 years determined through accelerated aging studies, longer than predicate's 5 years, but not raising new safety concerns. Abutments are supplied non-sterile and autoclaved by the end user (as expected for these components). |
| Biocompatibility | The device must be biocompatible, demonstrating no unacceptable levels of toxicity, irritation, sensitization, or local effects after implantation. | Tested per ISO 7405, ISO 10993-1, ISO 10993-3 (genotoxicity, carcinogenicity, reproductive toxicity), ISO 10993-5 (cytotoxicity), ISO 10993-6 (local effects after implantation), ISO 10993-10 (irritation and skin sensitization), ISO 10993-11 (systemic toxicity), and ISO 10993-12 (sample preparation).
