Device Description

Inclusive® Titanium Abutments are premanufactured prosthetic components directly connected to endosseous dental implants and are intended for use as an aid in prosthetic rehabilitation. Inclusive® Titanium Abutments are designed and fabricated to be compatible with Neoss® ProActive® Narrow Implant System, Neoss® ProActive® Standard Implant System, MIS® SEVEN® Implant System, and Zimmer® Eztetic® Implant System. The products are made from titanium alloy Ti-6A1-4V ELI, which meets ASTM standard F136. They include Inclusive® Titanium Abutment Blanks intended to be used to fabricate one-piece, all-titanium, patient-specific abutments using CAD/CAM technology and Inclusive® Titanium Abutments 4.5mmH intended to be used for support of fabricated crowns/bridges or a zirconia coping to complete the two-piece abutment. Inclusive® Titanium Abutments are a two-piece abutment with a titanium base and a ceramic top-half which when cemented together (Shofu MonoCem K020481) constitutes the final finished abutment. Each patient-specific abutment is prescribed by a clinician and manufactured by an authorized milling center validated by Prismatik Dentalcraft Inc. Inclusive® Titanium Abutments are provided non-sterile and intended for single use and prescription use.

Inclusive® Multi-Unit Coping is manufactured from titanium alloy, Ti-6A1-4V ELI conforming to ASTM F136 and used in conjunction with the Neoss® ProActive® Standard and MIS® SEVEN® multi-unit abutment. Inclusive® Multi-Unit Coping is bonded with the dental restoration prior to being seated on the multi-unit abutment via a multi-unit prosthetic screw. The non-engaging configuration of the multi-unit coping does not have an internal connection feature and seats onto the flat mating surface of the multi-unit abutment. The multi-unit coping is used in combination with screw-retained multi-unit dental prosthetics, e.g. bridges and bars, which are used to reconstruct the function and aesthetics of lost teeth. The multi-unit coping is straight with no angle correction and provided non-sterile. The device is intended for singe use and prescription use.

AI/ML Overview

This document is a 510(k) premarket notification for Inclusive® Titanium Abutments. It describes the device, its intended use, and provides a comparison to a predicate device to demonstrate substantial equivalence, rather than standalone performance criteria. Therefore, the information typically requested in your prompt regarding acceptance criteria and a study proving device meeting those criteria (especially for AI/software devices) is not directly applicable to this submission.

This is a submission for a physical medical device (dental abutments), and the "acceptance criteria" here refer to demonstrating substantial equivalence to a legally marketed predicate device, rather than the performance metrics of a diagnostic or AI algorithm.

However, I can extract the relevant information regarding the performance data and the aspects that were tested to demonstrate substantial equivalence, which serves a similar purpose in this context:

Summary of Performance Data (to demonstrate Substantial Equivalence):

Category	Acceptance Criteria (Implied by equivalence to predicate & standards)	Device Performance (Reported Findings)
Biocompatibility	No biocompatibility concern (following FDA Guidance and ISO 10993-1).	Concluded no biocompatibility concern. Material and manufacturing process are identical to predicate (K191222) and reference (K160979). Cytotoxicity testing (ISO 10993-5) referenced from K160979 demonstrating biocompatibility of final finished device (titanium abutment, zirconia coping, and cement).
Mechanical Properties	Sufficient strength for intended use (following FDA Guidance and ISO 14801:2016 for worst-case scenario).	Static load and fatigue testing performed according to ISO 14801:2016. Fatigue limit data demonstrated sufficient strength. Dimensional and reverse engineering analysis confirmed compatibility with OEM implant systems. Supports an increased angulation range from 20° to 30° compared to the predicate, with fatigue testing supporting this change.
Sterilization	Effective sterilization by end-user (following ISO 17665-1 and ISO 17665-2).	Device is provided non-sterile for steam sterilization by the end-user with parameters validated by ISO 17665-1 and ISO 17665-2, identical to predicate (K191222) and referenced devices (K083192, K160979). No additional sterilization testing conducted due to identical material, manufacturing, and facility.
Shelf Life & Packaging	Packaging suitable to withstand distribution environment (following ASTM D4169-16). No adverse effect from aging.	Material (Ti-6A1-4V ELI) known to be stable at room temperature indefinitely, so shelf-life is not applicable. Packaging validation according to ASTM D4169-16 was conducted and found suitable.
MR Environment	Safe for use in MR environment (based on scientific rationale and published literature).	Non-clinical MR review performed using scientific rationale and published literature, addressing parameters per FDA guidance "Testing and Labeling Medical Devices for Safety in the Magnetic Resonance (MR) Environment" based on component materials.

Additional Information based on the provided text:

Sample size used for the test set and the data provenance:
- Biocompatibility: The text does not specify a separate "test set" sample size for dedicated biocompatibility testing on this specific device, as it leverages existing data. It states, "additional biocompatibility testing was not conducted" due to identical materials, manufacturing, and facility as the predicate (K191222) and reference device (K160979). Cytotoxicity testing (ISO 10993-5) was referenced from K160979.
- Mechanical Properties: The document states that static load and fatigue testing was performed "with the worst-case scenario." It does not specify the number of samples tested for this specific submission, but it would have been a sufficient number to meet the requirements of ISO 14801:2016. Data provenance is implied to be internal testing by Prismatik Dentalcraft, Inc.
- Sterilization: No sample size is specified, as "additional sterilization was not conducted" for this submission due to identical materials, manufacturing, and parameters as predicate and reference devices. Validation was referenced from K083192 and K160979.
- Packaging: "A packaging validation according to ASTM D4169-16 was conducted" but no specific sample size is mentioned.
Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable. This is a physical device submission relying on established engineering standards and material properties, not an AI or diagnostic device that requires expert-established ground truth for its performance assessment.
Adjudication method (e.g. 2+1, 3+1, none) for the test set: Not applicable for a physical device submission for dental abutments.
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: Not applicable. This pertains to AI/software performance, not a physical dental implant component.
If a standalone (i.e. algorithm only without human-in-the-loop performance) was done: Not applicable. This pertains to AI/software performance.
The type of ground truth used (expert consensus, pathology, outcomes data, etc.):
- "Ground truth" in this context is based on established engineering standards (e.g., ISO 14801:2016 for dynamic loading, ISO 10993-1 for biocompatibility, ISO 17665-1/2 for sterilization, ASTM D4169-16 for packaging), material specifications (e.g., ASTM F136 for Ti-6Al-4V ELI), and dimensional analysis / reverse engineering for compatibility with OEM implant systems. Biocompatibility also referenced cytotoxicity testing (ISO 10993-5) from a previous submission.
The sample size for the training set: Not applicable. This is not an AI/machine learning device.
How the ground truth for the training set was established: Not applicable. This is not an AI/machine learning device.

DETERMINATION OF SUBSTANTIAL EQUIVALENCE

The subject device is substantially equivalent to the primary predicate device (K191222) listed above in intended use, material, design principles and technological characteristics. The subject device and the primary predicate device (K191222) include prefabricated, precision interface (implant/abutment connection) abutments that are manufactured from titanium alloy conforming to ASTM F136. The subject device and the primary predicate device (K191222) include Inclusive® Titanium Abutment Blanks intended to be used to fabricate one-piece, all-titanium, patient-specific abutments using CAD/CAM technology and Inclusive® Titanium Abutments 4.5mmH and 6mmH intended to be used for support of fabricated crowns/bridges or zirconia copings. Inclusive® Titanium Abutments are a two-piece abutment with a titanium base and a ceramic top half. Each patient-specific abutment is individually prescribed by the clinician and manufactured by Prismatik Dentalcraft, Inc. or a qualified validated milling center.

The Indications for Use Statement (IFUS) for the subject device is substantially equivalent to that of the primary predicate device (K191222) except the compatible implant system due to different implant connection. Both devices have the same intended use as endosseous dental implant abutments for the support of a prosthesis to restore chewing function.

The subject device designs are substantially equivalent to the corresponding design of the primary predicate device (K191222), including titanium blank abutments and titanium base abutments (engaging and non-engaging). The subject device and the primary predicate device (K191222) are for single-unit or multiple-unit restorations and for cement-retained or screw-retained prostheses. Both devices have internal implant interface connections and are made of titanium alloy Ti-6Al-4V conforming to ASTM F136 (abutments and abutment screws), and the titanium base abutments are to be used with zirconia superstructures.

The subject device includes designs for abutment angulation up to 30°; this angulation range is similar to the primary predicate device (K191222), but increased angulation range from 20° to 30°. The subject device is compatible with the following OEM implant systems, Neoss® ProActive® Narrow, Neoss® ProActive® Standard, MIS® SEVEN®, Zimmer® Eztetic®, and the compatibility of the subject device and the OEM implants was established by dimensional analysis and reverse engineering analysis regarding specific critical dimensions. When the subject device is used according to its difference does not impact safety or effectiveness. Furthermore, mechanical performance testing was performed according to ISO 14801:2016, "Dentistry - Implants - Dynamic loading test for endosseous dental implants" and demonstrated that the subject device has sufficient strength for its intended use.

The subject device is provided non-sterile and to be steam sterilized by the end-user. The validated moist heat sterilization method according to ISO 17665-1 and ISO 17665-2 is the same as the primary predicate device (K191222), and the reference devices K083192 and K160979. Substantial equivalence of the subject device components in terms of biocompatibility is supported by the fact that materials are identical in formulation,

Biocompatibility Evaluation

Biocompatibility evaluation was conducted by following the FDA Guidance Document, Use of International Standard ISO 10993-1, "Biological evaluation of medical devices – Part 1: Evaluation and testing within a risk management process" and concluded that there is no biocompatibility concern. The subject device has the same material and manufacturing process at the same manufacturing facility as the primary predicate device (K191222) and the reference device (K160979); therefore, additional biocompatibility testing was not conducted. Cytotoxicity testing according to ISO 10993-5 was referenced from K160979 to demonstrate the biocompatibility of the final finished device consisting of the titanium abutment, zirconia coping and cement. Biological evaluation was used to address questions related to substantial equivalence between the subject device and the primary predicate device (K191222) in terms of biocompatibility.

Mechanical Properties

Static load and fatigue testing of the implant/abutment assembly was considered according to the FDA Guidance Document. Guidance for Industry and FDA Staff Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Implant Abutments and ISO 14801:2016 standard with the worst-case scenario. The fatigue limit data demonstrated that the subject device has sufficient strength for its intended use. Reverse engineering of OEM implant bodies, OEM abutments, and OEM abutment screws was conducted to confirm compatibility. The results of the mechanical testing were used to address questions related to substantial equivalence based on the differences in technical specifications between the subject device and the primary predicate device (K191222).

Sterilization Validation

The subject device is provided non-sterile intended to be steam sterilized by the end user with the same parameters as the primary predicate device (K191222) as validated by ISO 17665-1 and ISO 17665-2. The subject device has the same material and manufacturing process at the same manufacturing facility as the primary predicate device (K191222) and the reference device (K160979); therefore, additional sterilization was not conducted. Sterilization validation according to ISO 17665-1 and ISO 17665-2 were referenced from K083192 and K160979. The results of the previous testing were used to address questions related to substantial equivalence based on the differences in technical specifications between the subject device and the primary predicate device (K191222).

The company name is written in blue, with "PRISMATIK" on the top line and "DENTALCRAFT, INC." on the bottom line.

Shelf Life and Packaging Validation

The subject device performance is not adversely affected by aging because the subject device is made from titanium alloy conforming to ASTM F136; this material is known to be stable in air at room temperature for an indefinite period of time. Shelf-life is not applicable because of low likelihood of time-dependent product degradation. A packaging validation according to ASTM D4169-16 was conducted to ensure that the packaging configurations for the subject device are suitable to withstand the distribution environment. It was determined that the packaging for the subject device is suitable for use. The results of the testing were used to address questions related to substantial equivalence based on differences in product packaging between the subject device and the primary predicate device (K191222).

Use in MR Environment

Non-clinical MR review was performed to evaluate the metallic devices in the MR environment using scientific rationale and published literature (e.g., Woods, Terry O., Jana G. Delfino, and Sunder Rajan. "Assessment of Magnetically Induced Displacement Force and Torque on Metal Alloys Used in Medical Devices." Journal of Testing and Evaluation 49.2 (2019): 783-795), based on the subject device components and material composition. Rationale addressed parameters per the FDA guidance "Testing and Labeling Medical Devices for Safety in the Magnetic Resonance (MR) Environment".

VIII. CONCLUSION

Based on the technological characteristics and non-clinical test data included in this submission, the subject device has been shown to be substantially equivalent to the predicate device (K191222).
