The summary describes a patient-specific CAD/CAM abutment and its manufacturing process, focusing on materials, compatibility, and mechanical performance. There is no mention of AI or ML in the intended use, device description, or performance studies.
Yes
The device is a patient-specific CAD/CAM abutment used to support prosthetic rehabilitation, directly connected to dental implants. It physically replaces or aids in the function of an anatomical part (tooth support) thereby fulfilling the definition of a therapeutic device.
No
The Tru Abutment DS is a patient-specific CAD/CAM abutment used for prosthetic rehabilitation to support a prosthetic restoration, not to diagnose a medical condition.
No
The device description explicitly states that the system includes patient-specific abutments made of Titanium grade Ti-6A1-4V ELI and supplied with screws, which are physical hardware components. The manufacturing process involves milling at a center.
Based on the provided text, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for "prosthetic rehabilitation" by providing support for a prosthetic restoration in the oral cavity. This is a mechanical function, not a diagnostic one.
- Device Description: The description focuses on the physical characteristics of the abutment (material, connection type, manufacturing process) and its role in supporting a dental prosthesis.
- Performance Studies: The non-clinical testing described (Fatigue Test, Sterilization Test, Biocompatibility tests) are related to the mechanical and biological safety of the device for implantation, not its ability to diagnose a condition.
- Lack of Diagnostic Elements: There is no mention of the device being used to analyze samples (blood, tissue, etc.), detect biomarkers, or provide information for diagnosing a disease or condition.
IVD devices are used to examine specimens derived from the human body to provide information for diagnostic purposes. This device is a physical component used in a dental restoration procedure.

Device Description
The TruAbutment DS system includes patient-specific abutments which are placed into the dental implant to provide support for a prosthetic restoration. The subject abutments are indicated for cemented or "Screw- and Cement-Retained Prosthesis" (SCRP) restorations. The patient-specific abutment and abutment screw are made of Titanium grade Ti-6A1-4V ELI (meets ASTM Standard F-I 36). 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. 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 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 proposed patient-specific abutments are available in internal connections and are compatible with:
- Astra Tech OsseoSpeed™ EV (K120414, K130999)
- Nobel Active™ Internal Connection Implant (K071370)
- Straumann® Bone Level Implants (K062129, K140878, K153758, K150938)

K172304
TruAbutment DS incorporates the same material, indication, design, abutment seat, screw seat, anatomical site, connection, type of retention and technological characteristics as the predicate device.
The Indications for Use of the subject and predicate devices are identical other than the compatible implant bodies. This difference is mirigated by fatigue testing, reverse engineering, dimensional analysis, and identification of reference predicate for compatible implant bodies. Both the predicate and subject devices are intended into patient specific abutments using CAD/CAM technology under the manufacturing control of the sponsor.
Any differences in technology characteristics are accompanied by information that device is substantially equivalent as the predicate and do not raise different questions of safety and effectiveness than the predicate.

Non-clinical Testing
The subject device was tested to evaluate its substantial equivalence according to the following standards.
-
. Fatigue Test according to ISO 14801:2007
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.
Biocompatibility and sterilization validation test data was used to evaluate the proposed device's substantial equivalence compared to the predicate device which is owned by the applicant. The results of the above tests have met the criteria of the standard, and demonstrated the substantial equivalence with the predicate device.
Non-clinical 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.
Dimensional analysis and reverse engineering (OEM implant bodies. OEM abutments, OEM fixation screws) of the implant-to-abutment connection platform were performed, including an assessment of maximum and minimum dimensions of critical design aspects, tolerances, and crosssectional 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 compatibility and has established substantial equivalency of the proposed device with predicate devices. Clinical testing was not necessary to establish substantial equivalency of the device.
Conclusion
The TruAbutment DS 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 device. Therefore, TruAbutment DS and its predicate are substantially equivalent.
