AI/ML Overview

The provided document is a 510(k) summary for the A.B. DENTAL DEVICES® Dental Implants System. It describes the device, its indications for use, and a comparison to predicate devices, focusing on the expansion of existing abutment lines and the addition of new ones. The document details the performance testing conducted to demonstrate substantial equivalence, primarily bench testing for mechanical properties and rationale for other characteristics.

Here's an analysis of the requested information based on the provided text:

1. Table of Acceptance Criteria and Reported Device Performance

The document does not explicitly present a table of acceptance criteria with corresponding performance values in the manner typically seen for algorithmic performance. Instead, it describes various tests and states that the differences in the subject device do not raise new issues or are addressed through testing to establish substantial equivalence to predicate devices. The "acceptance criteria" here are implicitly meeting the performance of the predicate devices or demonstrating that the modifications do not create a new worst-case scenario.

Aspect of Performance	Acceptance Criteria (Implicit)	Reported Device Performance
Mechanical Strength	- Subject device does not create a new mechanical worst-case compared to predicate (e.g., shorter moment arm, more material).	- Engineering analysis confirmed that new components do not constitute a new mechanical worst-case.
	- Meets or exceeds performance of predicate devices when tested per ISO 14801.	- Dynamic testing per ISO 14801 was performed on worst-case constructs, demonstrating substantial equivalence (e.g., narrow platform constructs demonstrated substantial equivalence to Straumann Crossfit SLA 3.3 mm (K111357), P64-3.75 shown equivalent to standard platform P14 abutment).
	- Modified screw (P4a-S) meets static torque to failure requirements and dynamic testing per ISO 14801.	- Static torque to failure testing conducted for modified P4a-S screw. Static and dynamic testing per ISO 14801 performed in the same construct. The results imply successful performance to support equivalence, though specific values are not provided.
Biocompatibility	Materials (Ti-6Al-4V ELI, Delrin, CoCr) are biocompatible and identical to those used in predicate devices.	- Application of ISO 10993-1, with a scientific rationale that biocompatibility testing was not needed as materials and manufacturing methods are identical to the sponsor's own predicate devices.
Cleaning/Sterility	Modifications do not create a new worst-case for cleaning or sterility. Sterilization process is validated per ISO 17665.	- Scientific rationale used to determine that additional components do not constitute a new cleaning or sterility worst-case. Sterilization validated per ISO 17665. The same color anodization (gold) has been cleared on other abutments in K162482, suggesting no new sterility issues related to this aesthetic change.

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

The document states that "worst-case construct(s)" were used for mechanical testing per ISO 14801. However, it does not specify the sample size (number of units) for these tests. It also does not provide information on the data provenance (e.g., country of origin, retrospective or prospective) as the tests are bench-based engineering tests rather than clinical studies with patient data.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Their Qualifications

This information is not applicable to this type of device and study. The "ground truth" here is based on engineering principles, material properties, and established test standards (like ISO 14801), not on expert consensus for clinical interpretations or diagnoses.

4. Adjudication Method for the Test Set

This information is not applicable as the tests are objective engineering measurements and evaluations against established standards, not subjective assessments requiring adjudication.

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

This is not applicable. The device is a dental implant system (hardware), not an AI or software as a medical device (SaMD) that involves human readers or clinical image interpretation.

6. If a Standalone (i.e. algorithm only without human-in-the-loop performance) Was Done

This is not applicable as the device is a dental implant system, not a software algorithm.

7. The Type of Ground Truth Used

The "ground truth" for this submission is based on:

Engineering principles and rationale: Used to determine if components constitute a "new worst-case" mechanically or for cleaning/sterility.
Standardized bench testing: Specifically mentioned ISO 14801 for mechanical fatigue testing and static torque to failure.
Biocompatibility standards: Application of ISO 10993-1.
Sterilization standards: Validation per ISO 17665.
Comparison to predicate devices: The established performance and characteristics of the legally marketed predicate devices serve as a benchmark for demonstrating substantial equivalence.

8. The Sample Size for the Training Set

This is not applicable. There is no "training set" in the context of this device submission, which involves physical implants and abutments rather than machine learning algorithms.

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

This is not applicable, as there is no training set mentioned or implied for this type of device.

P4 and P14 angled abutments are to be used only
with standard platform implants 3.5 mm in diameter
or larger.

The indications for the subject device and the indications cleared in K162482 are provided above. The only difference is the highlighted text which details a subset of AB Dental implants that were the subject of K162482 and compatibility limitations for the angled P4 and P14 abutments. The reference device Indications for Use do not include any component-specific additional language which would apply to the subject devices and therefore are not included in this comparison. In comparison to K162482, the subject device only differs in respect to indications related to the specific components contained within each submission. As K162482 dealt with implants (122, 15, l10) specific instruction related to these devices are contained in the indications but are omitted from this submission which does not modify these devices. The limitation to P4 and P14 abutments is also being removed, as this submission contains the required information to support use of angled abutments with narrow platform implants.

The purpose of this traditional 510(k) is to expand the current product line to include the new abutments listed below. No substantive changes are being made to the indications. Comparison tables for each modification are provided below.

Both standard length and long length narrow platform P4 abutments are being added as part of this 510(k). As their geometry is identical aside for differences in length, the standard length abutments are less worst-case than the long. Material, manufacturing methods (aside from color anodization), and sterility are identical between the subject and predicate device. The same color anodization has been cleared on other abutments in K162482.

These abutments are similar in design to the predicate P4S-3.75,15-(1,3) abutments and differ only in that they have a 25° angulation while the predicate abutments have 15° angulation. None-theless, an engineering rationale shows that the new abutments do not create a new-worst as compared to the previously cleared P4L-3.75,25 abutment. Specifically, while the angulation between the P4S-3.75,25 and the P4L-3.75,25 abutments are the subject P4S abutment is 2.5 mm shorter, and therefore has a shorter moment arm as compared to the predicate P4L-3.75,25 abutment. Material, manufacturing methods and sterility are identical between the subject and predicate device.

An engineering rationale shows that the angulation and length of the subject abutment is less than predicate, resulting in a shorter moment arm. Further, the wide diameter abutment has more material than a standard diameter abutment. Therefore, this abutment does not create a new, worstcase. Material, manufacturing methods, and sterility are identical between the subject and predicate device.

These abutments are similar in design to the predicate P5-P14 abutments in that both allow the P14 base to be used the proximal portion of another implant. For the predicate P5-P14 abutment, connection is made to a P5 abutment, while the subject device allows connection to a P25 abutment. The proximal geometry of the P25-P14 is identical to the proximal geometry of the P25 abutments cleared in K132125 and is compatible with the same class I exempt silicone caps. Material, manufacturing methods and sterility are identical between the subject and predicate device.

Dynamic testing of the worst-case narrow platform construct shows that the narrow platform abutment is substantially equivalent to the Straumann Crossfit SLA 3.3 mm (K111357) which has similar dimensions and materials. Material, manufacturing methods (aside from color anodization) and sterility are identical between the subject and predicate device. The same color anodization has been cleared on other abutments in K162482.

These abutments are similar in design to the predicate P14 abutments except that they are monolithic single-units while the predicate P14 abutments are composed of two different parts. Both abutments are intended for multi-unit loading and have the same maximum shoulder height and angulations. Dynamic testing of the worst-case narrow platform construct shows the P64-3.75 to be equivalent to the standard platform P14 abutment. Material, manufacturing methods and sterlity are identical between the subject and predicate device.

The two sleeves primarily differ in their distal geometry so that they fit their respective compatible abutments. Its addition is supported by the same information as the P64 abutment itself, as the two are evaluated together via dynamic testing. Material, manufacturing methods and sterility are identical for the subject and predicate device.

The caps differ with respect to their abutment mating geometry to match their respective abutments. The subject cap is only available in 5 mm height, while the predicate is available in additional shorter and longer heights. Material, manufacturing methods, and sterility are identical for the subject and predicate device.

Performance Data

Engineering analysis to determine if additional components constitute a new mechanical worst-case.
Testing per ISO 14801 in air on the worst-case construct.
Static torque to failure testing of modified P4a-S screw. In addition, static and dynamic testing per ISO 14801 in the same construct was conducted.
. Scientific rationale to determine if additional components constitute a new cleaning or sterility worst-case
. Application of ISO 10993-1 to justify that biocompatibility testing was not needed as materials and manufacturing methods are identical to the sponsor's own predicate
Sterilization validation per ISO 17665

Substantial Equivalence

The A.B. Dental Implants System has same intended use and similar technological characteristics and principles of operation as its predicate device. The minor technological differences between the A.B. Dental Implants Systems do not raise different issues. Performance data demonstrate that the A.B. Dental Implants System is substantially equivalent.

Conclusions

The A.B. Dental Implants System is substantially equivalent to the predicate device.
