It is indicated for screw-retained single tooth or cement-retained single tooth and bridge restorations. It is compatible with the following systems:
· Zimmer 3.1mmD Dental Implant System (K142082)

  TruBase S is intended to be sent to a TruAbutment-validated milling center for manufacture.

TruAbutment DS system includes patient-specific abutments that are placed into the dental implant to provide support for prosthetic restoration. The subject abutments are indicated for cemented or screwretained restorations. The patient-specific abutment screws are made of Titanium grade Ti-6A1-4V ELI (meets ASTM Standard F-136). Each patient-specific abutment is supplied with two identical screws which are used for:

• (1) For fixing into the endosseous implant
• (2) For dental laboratory use during construction of related restoration.
  The abutment is placed over the implant shoulder and mounted into the implant with the provided screw. The design and manufacturing of the patient-specific abutments take into consideration the shape of the final prosthesis based on the patient's intra-oral indications using the CAD/CAM system during the manufacturing. All manufacturing processes of TruAbutment DS are conducted at the TruAbutment milling center and provided to the authorized end-user as a final patient-specific abutment.

TruBase S consists of a two-piece abutment, where the titanium base is a pre-manufactured abutment that will be used to support a CAD/CAM designed superstructure (the second part of the two-piece abutment) that composes the final abutment. TruBase S abutments are made of titanium alloy conforming to ASTM F136 Standard Specification for Wrought Titanium-6Aluminum-4Vanadium ELI (Extra Low Interstitial) Alloy for Surgical Implant Applications and are provided in various prosthetic platform diameters (Zimmer 3.1mmD Dental Implant System: 2.9mm and Screw Vent® and Tapered Screw Vent®: 3.5, 4.5, 5.7mm). They also feature:

• . cylindrical shape
• . hexagonal indexing at the apical end of the connection
• . indexing guide in the cementable portion for coping fitting
  CAD/CAM customized superstructure that composes the final abutment is intended to be sent to a TruAbutment-validated milling center to be designed and milled, according to the prosthetic planning and patient clinical situation. The superstructure is cemented to the TruBase S in the lab. Use "RelyX Unicem 2Automix" as an adhesive extra orally to connect.
  TruBase S is provided non-sterile therefore must be sterilized after the cementation of the customized superstructure on the TruBase S.

The provided text is a 510(k) summary for a dental device, TruAbutment DS and TruBase S. It primarily focuses on demonstrating substantial equivalence to predicate devices based on design specifications, materials, and non-clinical testing (mechanical and biocompatibility).

This document does not contain information about studies involving human-in-the-loop performance, expert ground truth establishment, or clinical effectiveness studies in the context of AI/ML device performance. The "acceptance criteria" discussed are related to the mechanical properties and biocompatibility of the physical dental abutment and base, rather than the performance of an AI/ML algorithm.

Therefore, many of the requested points, such as sample size for test/training sets, experts for ground truth, adjudication methods, MRMC studies, or standalone algorithm performance, cannot be extracted from this document as they are not relevant to the type of device and testing described.

However, I can provide information based on the mechanical and material testing criteria that are present.

Here's an analysis of the provided text in relation to your request, with a clear indication of what information is not available:

Information Pertaining to Device Acceptance (Mechanical/Biocompatibility):

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

   The document describes design limitations and states that non-clinical testing (fatigue and biocompatibility) met the criteria of the standard, demonstrating substantial equivalence. It does not provide specific numerical performance results for the acceptance criteria, but rather states whether the device "met the criteria of the standard" (ISO 14801:2016 for fatigue, ISO 17665-1:2006, 17665-2:2009 and ANSI/AAMI ST79:2010 for sterilization, and ISO 10993 series for biocompatibility).

   For TruAbutment DS:

   Design Parameter	Design Limit (Acceptance Criteria)	Reported Performance (Qualitative)
   Abutment Angle	0~25°	Met design limit
   Cuff Height	0.5~6.0mm	Met design limit
   Diameter at abutment/implant interface	Ø3.5mm~Ø8.0mm	Met design limit
   Minimum Thickness	0.4 mm	Met design limit
   Length of abutment post	4~7 mm	Met design limit

   For TruBase S (Zirconia Superstructure):

   Design Parameter	Design Limit (Acceptance Criteria)	Reported Performance (Qualitative)
   Abutment Angle	0~15°	Met design limit
   Cuff Height	0.5~5 mm	Met design limit
   Diameter at abutment/implant interface	Ø5.0mm~Ø8.0mm	Met design limit
   Minimum Thickness	0.4 mm	Met design limit
   Length of abutment post	4~6 mm	Met design limit

   Non-Clinical Testing:

   Acceptance Criteria (Standard)	Reported Performance
   Fatigue Test (ISO 14801:2016)	"The fatigue limit data for all other implant lines demonstrated the construct strengths to be sufficient for their intended use."
   End User Steam Sterilization Test (ISO 17665-1:2006, 17665-2:2009, ANSI/AAMI ST79:2010)	"The results of the above tests have met the criteria of the standard, and demonstrated the substantial equivalence with the predicate device."
   Biocompatibility (ISO 10993-5:2009, ISO 10993-10:2010)	"The results of the above tests have met the criteria of the standard, and demonstrated the substantial equivalence with the predicate device."

2. Sample sized used for the test set and the data provenance:

   • Sample Size: Not explicitly stated for specific tests (e.g., how many abutments were fatigued). The document mentions "worst-case constructs" were subjected to testing.
   • Data Provenance: Not specified (e.g., country of origin). The studies appear to be non-clinical (laboratory testing) rather than human subject data. The studies are retrospective as they leverage data from previous 510(k) clearances (K152559).

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

   • Not applicable. The "ground truth" here is based on engineering standards (e.g., ISO 14801 for mechanical properties, ISO 10993 for biocompatibility) and direct physical measurements, not expert human interpretation of medical images or clinical outcomes.

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

   • Not applicable. This relates to human expert review and consensus, which is not part of the physical and mechanical testing described.

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:

   • Not applicable. This device is a physical dental implant component, not an AI/ML diagnostic or assistive imaging device.

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

   • Not applicable. This is not an AI/ML algorithm. It's a medical device that is CAD/CAM manufactured.

7. The type of ground truth used:

   • For mechanical performance: Compliance with ISO 14801:2016 standard. This involves objective physical measurements and material science.
   • For sterilization: Compliance with ISO 17665-1:2006, 17665-2:2009 and ANSI/AAMI ST79:2010 standards.
   • For biocompatibility: Compliance with ISO 10993-5:2009, ISO 10993-10:2010 standards.

8. The sample size for the training set:

   • Not applicable. This is not an AI/ML algorithm that requires a "training set" in the computational sense. The "training" for manufacturing is implied through the "TruAbutment-validated milling center."

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

   • Not applicable. As above, no computational "training set" is described. The manufacturing process relies on validated design parameters and material specifications.

In summary, this 510(k) submission successfully demonstrates substantial equivalence based on engineering design parameters, material properties, and adherence to established mechanical and biological safety standards for a physical dental implant component. It does not involve AI/ML technology or associated human-in-the-loop performance studies.
