Device Description

This submission includes fully threaded root-form dental implants with an internal cone and hexagon interface and mating abutments. The implants are provided in three diameters: Ø3.5, Ø4.0 and Ø5.0 mm. The implants are provided in a straight (0° angled) configuration only, with a 3.0 mm extended machined coronal section. The implants are provided in one prosthetic diameter (2.95 mm implants are provided in overall leneths of 8, 10, 11.5, 13, 16, 18 and 20 mm. The Ø4.0 mm implants are provided in overall lengths of 8, 10, 11.5, 13, 16, 18, 20, 22 and 24 mm. The Ø5.0 mm implants are provided in overall lengths of 8, 10, 11.5, 13, 16, and 18 mm.

This submission also includes: a Cover Screw, Healing Abutments in four diameters and multiple gingival heights, Titanium Cylinder Abutments for temporary restorations, Passive Abutments with a plastic burn-out component, Equator Overdenture Abutments in multiple gingival heights, Compact Conical Abutments in straight (0) and angled (17° and 30°) designs, TIB Abutment Bases, and abutment screws.

The Passive Abutments may be restored using either traditional cast-on workflows or digital CAD/CAM workflows using milled zirconia restorations (similar use to the TIB Abutment Bases).

Using the traditional cast-on workflow, the Passive Abutments function as UCLA castable abutments which interface with a plastic, burn-out sleeve used to fabricate a prosthesis that is bonded directly to the top of the abutment, limited to a straight (0°) restoration when utilizing precious metal cast-on restorations.

Using digital CAD/CAM workflows, the TIB Abutment Bases and Passive Abutments function as two-piece abutment designs, consisting of standard premanufactured titanium alloy abutments for supporting the second half (or top-half) of the abutment, a hybrid/crown dental restoration and mesostructure (SageMaxx Zirconia) bonded with cement (Ivoclar Vivadent Multilink Hybrid cement). The dental laboratory is to fabricate the mesostructure restoration by CAD/CAM technique out of zirconia. The TIB Abutment Bases and Passive Abutments then serves as the interface between the endosseous implant and the Zirconia restoration. The TIB Abutment Bases and Passive Abutments are designed to support the restoration on an endosseous implant in order to restore chewing function for the patient.

The mesostructured restoration is a CAD/CAM designed prosthesis milled out of Zirconia (SageMaxx Zirconia), which is designed to fit the abutment base in order to restore chewing function for the patient. Each restoration is custom designed using 3Shape Abutment Designer Software in order to meet the requirements of each patient on a case-by-case basis. Limitations have been put in place in 3Shape Abutment Designer in order to prevent malfunctioning of the restoration and a maximum allowable angulation of 20° for the mesostructured component.

All Single Platform SP1 implants are manufactured from unalloyed titanium conforming to ASTM F67, with a smooth machined collar (extended machined surface of 3 mm). The remainder of the entire endosseous threaded surface) is grit-blasted. The subject device implant material and surface is identical to the implants cleared in K222457 and K163060. The Cover Screw and Healing Abutments are manufactured from unalloyed titanium conforming to ASTM F67. The remaining Abutments are manufactured from titanium alloy conforming to ASTM F136. The abutment screws are manufactured from titanium alloy conforming to ASTM F136. All subject device components are manufactured in the same facilities using the same materials and manufacturing processes as used for the Southern Implants devices previously cleared in K222457 and K163060.

AI/ML Overview

The provided text describes a 510(k) premarket notification for the "Single Platform SP1 Implant System." This document focuses on demonstrating substantial equivalence to existing, legally marketed predicate devices, rather than proving that the device meets specific acceptance criteria through a clinical study or a standalone algorithm performance test.

Therefore, the requested information regarding "acceptance criteria" and "study that proves the device meets the acceptance criteria" in terms of clinical performance with statistical measures, expert reading, and ground truth establishment is not present in the provided document. The 510(k) pathway for medical devices typically relies on demonstrating that a new device is as safe and effective as a predicate device, rather than requiring new clinical efficacy studies unless there are significant technological differences or new intended uses that raise new safety or effectiveness questions.

The "Performance Data" section explicitly states: "No clinical data were included in this submission."

However, I can extract information related to the non-clinical performance data provided to support substantial equivalence and the device's characteristics compared to predicates.

Here's a breakdown of what is available:

1. Table of Acceptance Criteria and Reported Device Performance:
The document does not define specific "acceptance criteria" for clinical performance (e.g., sensitivity, specificity, accuracy) or report device performance against such metrics. Instead, it demonstrates through non-clinical testing that the device's mechanical, material, and functional properties are substantially equivalent to marketed predicate devices.

Here's a table summarizing the non-clinical performance data and findings:

Acceptance Criteria (Proxy: Demonstration of Substantial Equivalence via Non-Clinical Performance)Reported Device Performance (Findings)
Engineering AnalysisDemonstrated equivalence.
Dimensional AnalysisDemonstrated equivalence.
Sterilization Validation (ISO 11137-1, ISO 17665-1, ISO 17665-2)Validated.
Bacterial Endotoxin (USP 39-NF 34)Tested according to standard.
Static and Dynamic Compression-Bending (ISO 14801 Dentistry - Implants - Dynamic fatigue test for endosseous dental implants)Results demonstrated fatigue performance of the subject device that exceeds its indication.
Scanning and Milling Validation for Passive AbutmentsValidated.
MR Safety Testing (FDA Guidance Document "Testing and Labeling Medical Devices for Safety in the Magnetic Resonance (MR) Environment" - ASTM F2503, ASTM F2052, ASTM F2213, ASTM F2182, ASTM F2119)Subject devices "can be considered equally MR Safe as the predicate devices" (as tested on previously cleared devices and compared).
Biocompatibility Evaluations (ISO 10993-1)Supported by identical materials, processing, and storage conditions as predicate devices (referenced from K222457 and K163060).
Sterile Barrier Shelf LifeReferenced from K222457.
Validated Steam Sterilization Instructions (ISO 17665-2)Referenced from K193084 (for non-sterile components intended for end-user sterilization).
Software Validation Testing (FDA Guidance Document for Off-The-Shelf Software Use in Medical Devices)Software verification and validation testing provided for abutment design library, including restrictions to prevent designs outside allowable limits and locked design limitations/specifications. (referenced from K193084, applicable to TIB Abutment Bases and Passive Abutments for digital CAD/CAM workflows).

2. Sample Size Used for the Test Set and Data Provenance:

  • Test Set Sample Size: Not applicable in the context of clinical efficacy; the "test set" here refers to the non-clinical testing of the physical device. For example, "dynamic compression-bending testing was performed on worst-case subject device constructs." The exact number of constructs tested is not specified but would be dictated by the ISO standard.
  • Data Provenance: The document does not specify the country of origin for the non-clinical testing data directly, but the manufacturer is Southern Implants (Pty) Ltd from Irene, Gauteng, SOUTH AFRICA. The data is retrospective in the sense that it supports a submission for a new device, often using internal lab data.

3. Number of Experts Used to Establish Ground Truth and Qualifications:

  • This information is not applicable as no clinical study with human readers or ground truth established by experts for diagnostic performance was conducted or reported.

4. Adjudication Method for the Test Set:

  • Not applicable, as there was no human reader interpretation or clinical assessment requiring adjudication.

5. Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study:

  • No MRMC comparative effectiveness study was done. The submission explicitly states: "No clinical data were included in this submission." Therefore, no effect size of human readers improving with AI vs. without AI assistance is reported.

6. Standalone (Algorithm-Only) Performance:

  • Not applicable. This is a physical dental implant system, not an AI algorithm. The only "software" mentioned is for design (CAD/CAM workflow), and its validation is to ensure it prevents designs outside of allowable limitations.

7. Type of Ground Truth Used:

  • For the non-clinical performance data, the "ground truth" is established by adherence to recognized international standards (ISO, ASTM, USP) and internal engineering specifications. For instance, the "ground truth" for fatigue performance is the passing criteria defined by ISO 14801.

8. Sample Size for the Training Set:

  • Not applicable. This product does not involve machine learning or AI models that require a training set.

9. How the Ground Truth for the Training Set Was Established:

  • Not applicable as there is no training set for an AI/ML model.

Non-clinical data submitted to demonstrate substantial equivalence includes: engineering analysis; dimensional analysis; sterilization validation according to ISO 11137-1, ISO 17665-1, ISO 17665-1, ISO 17665-2; bacterial endotoxin according to USP 39-NF 34; static and dynamic compression-bending according to ISO 14801 Dentistry - Implants - Dynamic fatigue test for endosseous dental implants; scanning and milling validation for the Passive Abutments; and MR safety testing as per the recommendations of the FDA Guidance Document "Testing and Labeling Medical Devices for Safety in the Magnetic Resonance (MR) Environment".

Non-clinical data referenced, or relied upon to demonstrate substantial equivalence includes: biocompatibility evaluations according to ISO 10993-1 (referenced from K222457 and K163060); sterile barrier shelf life (referenced from K222457); validated steam sterilization instructions per ISO 17665-2 (applicable to the Passive Abutments and Titanium Abutment Bases (TIB) which are provided non-sterile and intended for end-user sterilization - referenced from K193084); software validation testing as per the FDA Guidance Document for Off-The-Shelf Software Use in Medical Devices (referenced from K193084); and scanning and milling validation for the Titanium Abutment Bases (TIB) (referenced from K193084).

No clinical data were included in this submission.

Software verification and validation testing was provided for the subject abutment design library to demonstrate use with the 3Shape Abutment Designer Software (only applicable to the TIB Abutment Bases and Passive Abutments when using the digital CAD/CAM workflows for milled zirconia restoration design). Software verification and validation testing was conducted to demonstrate that the restrictions prevent design of the top half component of the two-piece abutment outside of the allowable design limitations, including screenshots under user verification testing. In addition, the encrypted abutment design library was validated to demonstrate that the established design limitations and specifications are locked and cannot be modified within the abutment design library.

MR safety testing as per the recommendations of the FDA Guidance Document "Testing and Labeling Medical Devices for Safety in the Magnetic Resonance (MR) Environment'' (ASTM F2503, ASTM F2052, ASTM F2213, ASTM F2182, ASTM F2119) was performed on the previously cleared devices, K222457, PROVATA Implant System. The subject devices were compared to the predicate devices. The subject devices are not worst-case Southern Implants components in terms of material, size or shape and therefore the subject devices can be considered equally MR Safe as the predicate devices.

The surface treatment applied to the subject device implants is identical to that cleared in K163060 and K222457. All subject device components are for single-patient, single-use, and all are provided sterile (except the Passive Abutments and TIB Abutment Bases which are provided non-sterile identical to Passive Abutments and TIB Abutment Bases cleared in K222457, and the Passive Abutments cleared in K163060). Similarly, the components cleared in K163060 and K222457 are for single-patient, single-use and are provided sterile (excluding the Passive Abutments and TIB Abutment Bases).

{17}------------------------------------------------

Substantial equivalence of the subject device components in terms of biocompatibility is supported by the fact that materials are identical in formulation, processing, component interactions, and storage conditions to the predicate devices in K163060 and K222457.

In support of substantial equivalence of the Single Platform SP1 implants in terms of mechanical performance, dynamic compression-bending testing was performed according to ISO 14801. Dynamic testing was performed on worst-case subject device constructs. The results from the testing demonstrated fatigue performance of the subject device that exceeds its indication.

CONCLUSION

The subject device and the predicate devices have a significantly similar intended use, have similar technological characteristics, and are made of the same materials. The subject device and the predicate devices encompass the same range of physical dimensions, including diameter and length of the implants, and the diameter and angulation of the abutments. The subject device and the predicate devices are packaged in similar materials and sterilized using similar methods.

The data included in this submission demonstrate substantial equivalence to the predicate devices listed above.

§ 872.3640 Endosseous dental implant.

(a)
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.(b)
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)
