External Hex implants are fully-threaded, tapered, root-form dental implants with an external hexagonal abutment interface, and are threaded internally for attachment of mating multiple-unit abutments, cover screws, or healing abutments. The External Hex implants have a Co-Axis design with the prosthetic platform angled at 36° and 24° (inclined) from orthogonal to the long axis of the implant.

Additionally, the External Hex implants are provided in two configurations, regular surface and MSC surface implants. The regular surface implants are fully roughened excluding a machined collar at the coronal aspect of the implant. The MSC surface implants have an extended length of machined area at the coronal aspect of the implant, with the remaining implant length being roughened.

The implants subject to this submission are the External Hex IBR36d and IBR24d implant range. The reduced platform MSC-IBR24d implants are only provided as Co-Axis implants, in both the regular surface and MSC surface configuration. The reduced platform IBR36d implants are only provided as Co-Axis implants, in regular surface configuration. The IBR36d implants are available in two body configurations depending on the implant length.

The IBR36d implants of overall lengths 8.5 mm to 18 mm have a major body diameter of 4.20 mm tapering to 2.60 mm. The IBR36d implants of overall lengths 20 mm to 24 mm have a major body diameter of 4.20 mm tapering to 2.00 mm. Both the IBR24d and MSC-IBR24d implants of overall lengths 20 mm have a major body diameter 4.07 mm tapering to 2.60 mm. All of the subject device implants utilize the same prosthetic connection, previously cleared in K163634.

All External Hex implants are manufactured from unalloyed titanium (cold-worked, grade 4, UTS ≥ 900 MPa). The MSC-IBR24d implants have a smooth machined surface of length 3 mm extending parallel from the implant prosthetic platform for all implant lengths. The remainder of the implant is grit-blasted with aluminum oxide particles to provide a surface roughness of 1-2 um. The subject device implant material and surface are identical to those of the implants cleared in K163634.

The IBR36d and IBR24d External Hex implants are provided with a dedicated pre-mounted fixture mount of 36° and 24 respectively, similar to that provided with the other Co-Axis External Hex implants cleared in K163634.

All of the subject device implants utilize the same prosthetic connection, previously cleared in K163634 for the External Hex IBR24d and MSC-IBR24d implants. The External Hex implants are used in conjunction with the same abutments cleared for use with the External Hex IBR24d implants (implants cleared in K163634). These abutments are cleared in K053478, K070841, K093562, and K163634. The components that are compatible with the External Hex implants include Cover Screw, Healing Abutment, and Compact Conical Abutments. The Compact Conical Abutments are compatible with Temporary Titanium Abutment Cylinders, Gold Abutment Cylinders, and Passive Abutments.

The subject device Co-Axis implants are indicated for use with straight multiple-unit abutments with a 0° allowable restoration angle, only. This includes restricting straight abutments, that can be restored on a multi-unit abutment, that have an allowable restoration angle of up to 20° associated with them, so that they may only have a restoration angle of 0°. Thus, all the possible compatible abutments will have a 0° allowable restoration angle.

All External Hex implants are provided sterile to the end-user in a single-unit package, and are for single-patient, single-use only.

The provided text describes the 510(k) summary for the "External Hex Implant System" and references performance data to support its substantial equivalence to legally marketed predicate devices. However, it does not contain explicit "acceptance criteria" for the device, nor a study design with specific performance metrics against those criteria in the way typically seen for AI/ML device evaluations.

Instead, the document focuses on demonstrating substantial equivalence based on non-clinical performance data (mechanical testing and biocompatibility) and clinical literature review. The clinical literature review is used to show that similar devices with comparable characteristics (e.g., angulation, length) have proven safe and effective.

Therefore, I cannot directly provide a table of acceptance criteria and reported device performance with specific metrics like sensitivity, specificity, or AUC, as these are not defined or reported in the provided text. The "performance" discussed relates to the device's mechanical strength and the success rates of similar implants documented in clinical literature, not an AI algorithm's diagnostic performance.

However, I can extract the relevant information regarding the studies referenced to support the device's safety and effectiveness, interpreting "acceptance criteria" as the demonstration of substantial equivalence through various assessments:

Interpretation of "Acceptance Criteria" for this device:

For this device, "acceptance criteria" are not quantitative performance metrics in the traditional sense for diagnostic AI. Instead, they are met by demonstrating the device's substantial equivalence to legally marketed predicate devices through:

• Biocompatibility: Conformance to ISO 10993-1.
• Mechanical Performance: Conformance to ISO 14801 (static and dynamic compression-bending fatigue test), with results showing sufficient strength for intended use.
• Sterilization: Conformance to ISO 11137-1, ISO 11137-2, and USP 39-NF 34 for bacterial endotoxin.
• Dimensional Analysis: Verification of critical dimensions.
• Clinical Safety and Performance (via Literature Review): Demonstrated favorable survival rates and clinical indices for comparable implants under similar conditions and specifications (length, angulation, loading protocols). This implicitly acts as an "acceptance criterion" for clinical effectiveness by showing established safety and effectiveness of similar devices.
• MR Safety: Conformance to FDA Guidance Document "Testing and Labeling Medical Devices for Safety in the Magnetic Resonance (MR) Environment" (ASTM F2503, ASTM F2013, ASTM F2182, ASTM F2119).

Summary of Information from the Provided Text:

1. Table of "Acceptance Criteria" (interpreted as equivalence demonstration points) and "Reported Device Performance":

| Area of "Acceptance Criteria" (Demonstration of Equivalence) | Reported Device Performance / Evidence |
| Biocompatibility | Evaluated according to ISO 10993-1 (referenced from K163634). |
| Mechanical Performance (Static & Dynamic Compression-Bending) | Testing to ISO 14801 was performed on representative worst-case constructs for angulation and abutment/screw materials. Twelve (12) samples for each subject device group were subjected to fatigue testing. The fatigue limit was determined to be where a total of three (3) samples endured 5 x 10^6 cycles with no failures. Results confirmed that the strength of the subject device is sufficient for its intended use. |
| Sterilization & Shelf Life | Sterilization according to ISO 11137-1, ISO 11137-2. Bacterial endotoxin according to USP 39-NF 34. Sterile barrier shelf life (referenced from K222457). |
| Dimensional Analysis | Performed. (No specific values reported in this section, but implied to meet design specifications). |
| Clinical Safety & Performance (Standard Length IBR36d) | Retrospective analysis of real-world clinical data (literature review). The literature review demonstrated that implants with lengths of 7-18mm and angulation range of 20-50° as part of a splinted approach showed similar success rates to standard implants. Survival rates and clinical indices were favorable in both maxillary and mandibular applications, with immediate and delayed loading protocols. The subject device (8.5-18mm lengths, 36° angle) falls within this "window of successful implants." |
| Clinical Safety & Performance (Extra Length IBR36d) | Retrospective analysis of real-world clinical data (literature review). The literature review supported the use of long implants (10-25mm) placed at angles of 15-90° in the pterygoid region, showing similar success rates to standard implants. The subject device (20-24mm lengths, 36° angle) falls within this "window of successful implants." |
| MR (Magnetic Resonance) Safety | MR safety testing (ASTM F2503, F2013, F2182, F2119) was performed on previously cleared devices (referenced from K222457). The subject devices are considered equally MR Safe as the predicate devices because they are not worst-case components in terms of material, size, or shape. |

The Single Platform SP1 Implant System is intended for surgical placement in the upper or lower jaw to provide a means for prosthetic attachment of crowns, bridges or overdentures utilizing delayed or immediate loading. The Single Platform SP1 Implant System is intended for immediate function when good primary stability with appropriate occlusal loading is achieved.

The Single Platform SP1 implants in lengths 20, 22 and 24 mm when placed in the maxilla are only indicated for multiple unit restorations in splinted applications that utilize at least two implants.

For the conventional abutment and screws:

The Conventional Abutments and Prosthetic Screws are premanufactured prosthetic components directly connected to endosseous dental implants and intended for use in fully edentulous maxilla and/or maxilla and/or mandible to provide support for crowns, bridges or overdentures.

For the Titanium Abutment Bases and Passive Abutments:

The TIB and Passive Abutments are premanufactured prosthetic components directly connected to endosseous dental implants and are intended for use as an aid in prosthetic rehabilitation. The TIB and Passive abutments consist of two major parts. Specifically, the titanium base and mesostructure components make up a two-piece abutment. The system integrates multiple components of the digital dentistry workflow: Scan files from desktop scanners, CAD software, CAM software, ceramic material, milling machine and associated tooling and accessories.

For the Temporary Titanium Cylinders:

The Southern Implants Temporary Titanium Abutments are prosthetic components directly connected to endosseous dental implants and are intended for provisional use up to 180 days as an aid in prosthetic rehabilitation.

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.

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:

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.

The Angulated Screw Channel (ASC) Solution Abutments and SI-BASE Abutments are premanufactured prosthetic components directly connected to endosseous dental implants and are intended for use as an aid in prosthetic rehabilitation. The ASC Solution Abutments and SI-BASE Abutments consist of two major parts. Specifically, the titanium base and mesostructure components make up a multi-piece abutment. The system integrates multiple components of the digital dentistry workflow: Scan files from desktop scanners, CAD software, CAM software, ceramic material, milling machine and associated tooling and accessories.

The intended use for the engaging ASC Solution Abutments and SI-BASE Abutments used with the Ø3.0 External-Hex implants, Ø3.3 PROVATA implants and Ø3.5/Ø4.0 Deep Conical implants are intended for use with a straight mesostructure component.

The intended use for the engaging ASC Solution Abutments and SI-BASE Abutments used with the Ø3.4 and Ø4.0 External-Hex implants. PROVATA implants and 03.5 and 04.3 TRI-NEX implants is limited to replacement of maxillary and mandibular lateral and central incisors.

The ASC Solution Abutments and SI-BASE Abutments for Compact Conical Abutments are intended for use on straight Compact Conical Abutments with a straight mesostructure component.

This submission includes two major components which make up the ASC Solution and SI-BASE Abutments - The ASC Solution and SI-BASE Abutment Base and the mesostructure restoration. Twopiece and three-piece abutments models are included. Two-piece abutments consist of the ti-base abutment and mesostructure. Three-piece abutments consist of the ti-base abutment, mesostructure, and compatible compact conical abutments.

The ASC Solution and SI-BASE Abutments are standard premanufactured titanium alloy abutments for supporting a dental restoration and mesostructure. The dental laboratory is to fabricate the mesostructure restoration by CAD/CAM technique out of zirconia. The ASC Solution and SI-BASE Abutments then serve as the interface between the endosseous implant and the zirconia restoration. The 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, 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.

The ASC Solution and SI-BASE Abutments are compatible with the Southern Implants' Deep Conical, External Hex, Provata and Tri-Nex implants and screws. The abutments are manufactured from Titanium alloy conforming to ASTM F136 and are color coded by Titanium nitride coating (ASC Solution Abutments) or yellow anodizing (SI-BASE Abutments). The TiN coating and anodization processes are the same as used for previously cleared anodized titanium alloy devices in K163634. The Mesostructure restoration is to be manufactured from Zirconia - Sage Max NexxZr which has been previously cleared for use in K130991.

The digital workflow includes the following products (not subject devices to this submission):

• Ceramic material: Sage Max NexxZr Zirconia Restorative material (K130991)
• Cement: Ivoclar Vivadent Multilink Hybrid Abutment Cement (K130436)
• Intra-oral scanner: 3Shape E3 Desktop Scanner
• Abutment design software: 3Shape Abutment Designer Software (K151455)
• Milling machine: Roland DWX51D Milling Unit

The provided text describes the Angulated Screw Channel (ASC) Solution Abutments and SI-BASE Abutments for dental implants. The document is a 510(k) summary submitted to the FDA to demonstrate substantial equivalence to legally marketed predicate devices.

1. A table of acceptance criteria and the reported device performance

The document does not explicitly state "acceptance criteria" in a quantitative manner with defined thresholds. Instead, it demonstrates compliance through comparison to predicate devices and adherence to relevant standards and guidance documents. The "reported device performance" is largely qualitative and comparative, focusing on demonstrating equivalence rather than meeting specific numerical performance targets.

However, based on the "PERFORMANCE DATA" section and "Table of Substantial Equivalence", we can infer the following:

2. Sample sizes used for the test set and the data provenance

• Sample Sizes for Test Set:
  • Biocompatibility: Not explicitly stated as a number of devices. The statement mentions "materials are identical in formulation, processing, component interactions, and storage conditions to the predicate device" and "biocompatibility testing per the FDA Guidance Document for Use of Standard ISO 10993-1... and ISO 10993-5 'Biological Evaluation of Medical Devices - Part 5: Tests for In-Vitro Cytotoxicity' was performed." This implies biological samples were used for in-vitro cytotoxicity, but the number is not specified.
  • Mechanical Performance (Fatigue): "Dynamic testing was performed on worst-case subject device constructs." The exact number is not provided, but typically, mechanical fatigue testing involves a statistically significant number of samples per "worst-case construct" to establish fatigue limits.
  • Software Validation: Not explicitly stated as a numerical sample size. It involved verification and validation for the "abutment design library" and screenshots under user verification testing, indicating a functional test rather than a numerical sample size.
  • MR Safety: Not explicitly stated for the subject device. It refers to testing performed on "previously cleared devices, K222457, PROVATA Implant System."
• Data Provenance: Not explicitly stated for any of the tests. Given it's a 510(k) summary, the testing was likely conducted by or on behalf of Southern Implants (Pty) Ltd, which is located in "Irene, Gauteng, 0062 South Africa." The studies appear to be non-clinical (bench testing) and retrospective in the sense that they rely on comparisons to previously cleared devices and established standards, rather than new prospective human clinical trials.

3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts

This information is not provided in the document. The studies described are primarily non-clinical bench testing, software validation, and biocompatibility assessments, which typically do not involve establishing "ground truth" through expert consensus in the way a diagnostic AI device would. Instead, performance is measured against engineering specifications, standards (like ISO 14801), and equivalence to predicate devices.

4. Adjudication method (e.g., 2+1, 3+1, none) for the test set

This information is not applicable to the types of non-clinical, hardware-focused studies described. Adjudication methods are typically used in clinical studies or studies evaluating subjective interpretations (e.g., image reading) to establish a consensus ground truth.

5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance

There was no MRMC comparative effectiveness study and no mention of AI assistance. This device is a component for dental implants (abutments), not a diagnostic AI system or an AI-assisted diagnostic tool.

6. If a standalone (i.e., algorithm only without human-in-the-loop performance) was done

This information is not applicable. The device is a physical medical component (dental abutment) and related software for design. While software validation was performed, it's for design limitations and functionality, not for an "algorithm only" performance in a diagnostic or interpretive sense. The "standalone" concept typically applies to AI algorithms that provide a diagnosis or interpretation without human intervention.

7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)

The concept of "ground truth" as it applies to diagnostic or prognostic data is not directly applicable to these non-clinical studies. Instead, the "truth" or reference for the tests described is:

• Biocompatibility: Established biological safety standards (ISO 10993-1, ISO 10993-5) and comparison to predicate device materials.
• Mechanical Performance: International standard ISO 14801 for dynamic fatigue testing of dental implants and abutments. This involves objective physical measurements.
• Software Validation: Functional specifications of the software and demonstration that defined design limitations are enforced.
• MR Safety: FDA guidance document recommendations and physical testing methods to determine MR compatibility.

8. The sample size for the training set

This information is not applicable. This device is not an AI diagnostic or predictive algorithm that requires a training set in the conventional sense. The "design workflow" involves CAD/CAM software but this refers to a process for custom fabrication, not machine learning model training.

9. How the ground truth for the training set was established

This information is not applicable for the same reasons as point 8.
