More Information

No
The summary describes a CAD/CAM system for designing and manufacturing dental abutments and bases. While it uses digital design and milling, there is no mention of AI or ML being used in the design process or any other aspect of the device's function. The focus is on compatibility with existing implant systems and mechanical performance testing.

No
The device, TruAbutment DS, is intended for prosthetic rehabilitation as an aid directly connected to dental implants. It provides support for patient-specific prosthetic restorations but does not directly treat a disease or condition.

No

The device is described as a patient-specific CAD/CAM abutment and titanium component for prosthetic rehabilitation, providing support for crowns or copings. Its intended use is mechanical support for restorations, not diagnosis. The performance studies focus on mechanical strength and compatibility, not diagnostic accuracy.

No

The device description explicitly details physical components made of titanium alloy (patient-specific abutments, abutment screws, TruBase, TruBase screws) and mentions manufacturing processes at a milling center. While CAD/CAM is used for design, the final product is a physical medical device.

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

Here's why:

  • Definition of IVD: In Vitro Diagnostic devices are used to examine specimens taken from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
  • Intended Use: The intended use of TruAbutment DS and TruBase is for prosthetic rehabilitation, specifically as components that connect to dental implants to support crowns or other restorations. This is a mechanical function within the oral cavity.
  • Device Description: The device description details the materials (titanium alloy) and how the abutments are designed and manufactured to fit dental implants and support prosthetics. There is no mention of analyzing biological specimens.
  • Anatomical Site: The anatomical site is the Oral Cavity, which is where the device is physically placed, not where biological samples are collected for analysis.
  • Performance Studies: The performance studies described focus on mechanical properties like fatigue strength and dimensional compatibility with dental implants. These are not studies related to the accuracy of diagnostic tests.

The device is a dental prosthetic component, not a diagnostic tool that analyzes biological samples.

General Description

TruAbutment DS

TruAbutment DS system includes patient-specific abutments which are placed into the dental implant to provide support for the prosthetic restoration. The subject abutments are indicated for cemented or screw-retained restorations. The patient-specific abutment and abutment screw are made of Titanium grade Ti-6A1-4V ELI (meets ASTM Standard F-136). Each patientspecific 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 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.

Mechanical resistance of the implant-abutment connection is essential to ensure the correct long-term functional performance of the complete dental restoration. Dimensional compatibility and mechanical performance of bases and screws together with the underlying implant are of primary importance. These concepts are the basis upon which the system design characteristics and functional performance are established.

The TruAbutment DS is a device that can only be sold, distributed, or used upon the order of an authorized healthcare provider, generally referred to as prescription (Rx) devices.

The TruBase screws are composed of titanium alloy per ASTM F136.

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 in the lab. Use "RelyX Unicem 2Automix" as an adhesive extra orally to connect.

TruBase is provided non-sterile therefore must be sterilized after the cementation of the customized superstructure on the TruBase.

The TruBase is a device that can only be sold, distributed, or used upon the order of an authorized healthcare provider, generally referred to as prescription (Rx) devices.

Substantial Equivalence Discussion

The subject device (TruAbutment DS) is substantially equivalent in indications and design principles to the primary predicate device and the reference devices listed above. The provided tables are comparing the Indications for Use Statements and the technological characteristics of the subject device, the primary predicate device.

The Indications for Use Statement (IFUS) for the subject device (TruAbutment DS) is substantially equivalent in intended use to the primary predicate device (K202579). All are intended for use with endosseous dental implants in the maxilla and mandible to provide functional and esthetic rehabilitation of the edentulous maxilla and mandible.

Slight differences in the language of the subject device (TruAbutment DS) and primary predicate (K202579) Indications for Use statements do not affect the intended use as an endosseous dental implant abutment for support of a prosthesis to restore chewing function.

The minor differences between the subject device (TruAbutment DS) and the primary predicate device (K202579) are related to the compatible OEM implant lines and the implant platform diameter.

The following subject device (TruBase) is substantially equivalent in indications and design principles to the primary predicate device(K202579) listed above. The subject device (TruBase) and the primary predicate device(K202579) have internal implant interface connections and are made of Ti-6A1-4V ELI (abutments and abutment screws).

The subject devices (TruAbutment DS, TruBase) are to be sterilized by the end-user, the same as primary predicate devices (K202579).

Sterilization validation for the subject devices (TruAbutment DS, TruBase) was performed according to ISO 17665-1 and ISO 17665-2. This sterilization method is the same as the primary predicate devices (K202579).

Mechanical performance testing was performed according to ISO 14801. For compatible OEM implant line, worst-case constructs were subjected to static compression and compression fatigue testing. The fatigue limit data for all other implant lines demonstrated the construct strengths to be sufficient for their intended use.

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 the reference device (K152559, K200817) 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 criteria of the standard and demonstrated the substantial equivalence with the predicate device.

Dimensional analysis and reverse engineering of the implant-to-abutment connection platform 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 OEM implant body, OEM abutment, and OEM fixation screw. The testing demonstrated implant to abutment compatibility and has established substantial equivalency of the proposed device with predicate devices.

Comparative fatigue testing of the subject and predicate devices was conducted in accordance with ISO 14801 and FDA Guidance "Class II Special Controls Guidance Document: Rootform Endosseous Dental Implants and Endosseous Dental Implant Abutments", and it consisted of testing finished assembled implant/abutment systems.

Conclusion

The TruAbutment DS, TruBase constitutes a substantially equivalent medical device, meeting all the declared requirements of its intended use. This system has the same intended use and fundamental scientific technology as its predicate devices. Therefore, TruAbutment DS, TruBase, and its predicate are substantially equivalent.
