More Information

No
The summary describes a physical dental implant component and its use with standard CAD/CAM software and milling units, with no mention of AI or ML.

Yes
The device is a titanium component that provides support for prosthetic dental restorations, thus restoring the function of a missing tooth.

No

The TruBase S is a titanium component designed to support prosthetic dental restorations. Its function is to provide structural support for crowns or copings, not to diagnose medical conditions or analyze patient health data.

No

The device is a titanium component (hardware) used in dental implants, not solely software. While it interacts with CAD/CAM software for design, the core device is a physical implant component.

Based on the provided information, this device is not an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use: The intended use is to provide support for patient-specific prosthetic restorations (copings or crowns) connected to dental implants. This is a structural and mechanical function within the body.
  • Device Description: The device is a titanium component designed to be physically connected to a dental implant and support a dental prosthesis.
  • Lack of Diagnostic Function: There is no mention of the device being used to test samples from the human body (like blood, urine, tissue, etc.) to provide diagnostic information about a disease or condition.
  • Focus on Mechanical and Structural Properties: The performance studies mentioned (fatigue testing, sterilization, biocompatibility) are related to the device's physical integrity, safety for implantation, and compatibility with the body, not its ability to diagnose.

IVD devices are specifically designed to perform tests in vitro (outside the body) on biological samples to provide diagnostic information. This device is an implantable medical device used for prosthetic support in vivo (within the body).

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Non-clinical Testing:
The subject device was tested to evaluate its substantial equivalence according to the following standards.

  • Fatigue Test according to ISO 14801:2016
    Below tests were performed for predicate device, K152559 and leveraged for the subject device:
  • End User Steam Sterilization Test according to ISO 17665-1:2006, 17665-2:2009 and ANSI/AAMI ST79:2010.
  • Biocompatibility tests according to ISO 10993-1:2009, ISO 10993-5:2009, and ISO 10993-10:2010.
    Non-clinical test data was used to evaluate the proposed device's substantial equivalence compared to the predicate device. The results of the above tests have met the standard, and demonstrated the substantial equivalence with the predicate device.

Mechanical Testing:
Mechanical Testing was conducted in accordance with FDA Guidance "Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Implant Abutments", and it consisted of testing finished assembled implant/abutment systems of the worst-case scenario, (smallest diameter with maximum angulation) through fatigue testing. The fatigue limit demonstrates the substantial equivalence. The results of the fatigue test have met the criteria of the standard, ISO 14801:2016, and demonstrated the substantial equivalence with the predicate device.

Dimensional analysis and reverse engineering:
Dimensional analysis and reverse engineering the OEM implant body, OEM implant abutment and OEM abutment fixation screw including all the connection platforms (implant-to-abutment-to-mesostructure) were performed, including an assessment of maximum and minimum dimensions of critical design aspects, tolerances, and cross-sectional images of the submission device and compatible implant body as well as the OEM implant abutment and implant body. The testing demonstrated implant-to-abutment-to-mesostructure compatibility and has established substantial equivalency of the proposed device with predicate devices.

Software Verification and Validation Testing:
The recommended software was considered as a "moderate" level of concern, since a failure or latent design flaw could directly result in minor injury to the patient or operator. Therefore, the subject TruBase S was verified and validated with respect to its functionality and design using the Sirona validated workflow. The recommended CAD/CAM System is the same used for the primary predicate device and the validation performed was based on the validation presented by the manufacturer of the primary predicate device.

Summary of Technological Characteristics

Both the subject and the reference devices have the same indication of providing support for prostheses. All devices are pre-manufactured titanium bases made of titanium (Ti-6AI-4V ELI), designed to be used as a base when fabricating a CAD/CAM patient-specific superstructure and are compatible with the same CAD/CAM system and blocks of raw material. A clinician or dental laboratory equipped with the Sirona Dental CAD/CAM System will design and mill the patient-specific superstructure, which composes the final medical device after the bonding to TruBase S.

The subject devices differ from the primary predicate devices cleared under K151324 only in the portion of implant connection, which is specific for each manufacturer. The cementable portion is identical and compatible with the Sirona Dental CAD/CAM System and the blocks of raw material. In the end of this section a comparison between the features of subject device and its predicate devices is shown in a tabular format.

Non-clinical Testing

The subject device was tested to evaluate its substantial equivalence according to the following standards.

  • Fatigue Test according to ISO 14801:2016 ●
    Below tests were performed for predicate device, K152559 and leveraged for the subject device:

  • End User Steam Sterilization Test according to ISO 17665-1:2006, 17665-2:2009 and ● ANSI/AAMI ST79:2010.

  • Biocompatibility tests according to ISO 10993-1:2009, ISO 10993-5:2009, and ISO 10993-● 10:2010.

Non-clinical test data was used to evaluate the proposed device's substantial equivalence compared to the predicate device. The results of the above tests have met the standard, and demonstrated the substantial equivalence with the predicate device.

Mechanical Testing

Mechanical Testing was conducted in accordance with FDA Guidance "Class II Special Controls Guidance Document: Root-form Endosseous Dental Implants and Endosseous Dental Implant Abutments", and it consisted of testing finished assembled implant/abutment systems of the worst-case scenario, (smallest diameter with maximum angulation) through fatigue testing. The fatigue limit demonstrates the substantial equivalence. The results of the fatigue test have met the criteria of the standard, ISO 14801:2016, and demonstrated the substantial equivalence with the predicate device.

Dimensional analysis and reverse engineering

Dimensional analysis and reverse engineering the OEM implant body, OEM implant abutment and OEM abutment fixation screw including all the connection platforms (implant-to-abutment-tomesostructure) were performed, including an assessment of maximum and minimum dimensions of critical design aspects, tolerances, and cross-sectional images of the submission device and compatible implant body as well as the OEM implant abutment and implant body. The testing demonstrated implantto-abutment-to-mesostructure compatibility and has established substantial equivalency of the proposed device with predicate devices.

Software Verification and Validation Testing

The recommended software was considered as a "moderate" level of concern, since a failure or latent design flaw could directly result in minor injury to the patient or operator. Therefore, the subject TruBase S was verified and validated with respect to its functionality and design using the Sirona validated workflow. The recommended CAD/CAM System is the same used for the primary predicate device and

10

the validation performed was based on the validation presented by the manufacturer of the primary predicate device.

Note: TruAbutment makes no changes to the software, its setting or configuration, as well as no modification in the workflow defined and validated by Sirona per K111421. The Sirona software is recommended because of the compatibility of its existing 3D models with the subject device.
