It is compatible with the following systems: - · Astra Tech OsseoSpeed™ EV 3.0. 3.6, 4.2, 4.8, 5.4 mm - · Nobel Active™ Internal Connection Implant 3.5, 4.3, 5.0, 5.5 mm - · Straumann® Bone Level Implants 3.3, 4.1, 4.8 mm All digitally designed abutments and/or coping for use with the TruAbutments are intended to be sent to a TruAbutment-validated milling center for manufacture.

Device Story

TruAbutment DS is a patient-specific CAD/CAM dental abutment system. It functions as an interface between an endosseous dental implant and a prosthetic restoration (crown/bridge). The device is manufactured at a validated milling center using digital design data. The abutment and its fixation screw are fabricated from Titanium alloy (Ti-6Al-4V ELI). The clinician selects the abutment compatible with specific implant systems (Astra Tech, Nobel Active, or Straumann). The abutment is placed over the implant shoulder and secured with the provided screw. The system provides mechanical support for the final dental prosthesis. It is used in dental clinics by dental professionals. The device benefits patients by providing a customized, stable connection for prosthetic rehabilitation, ensuring functional performance through precise dimensional compatibility with the underlying implant.

Clinical Evidence

No clinical data. Substantial equivalence established via bench testing, including fatigue testing per ISO 14801:2007, dimensional analysis, and reverse engineering of implant-to-abutment connections. Biocompatibility (ISO 10993) and steam sterilization (ISO 17665) data were leveraged from previous predicate testing.

Technological Characteristics

Material: Titanium alloy Ti-6Al-4V ELI (ASTM F-136). Design: Patient-specific CAD/CAM machined abutment. Connection: Internal connections (Spline, Hex, Cross Fit). Energy source: None (mechanical). Sterilization: Supplied non-sterile, intended for steam sterilization. Connectivity: Digital workflow for CAD/CAM manufacturing.

Indications for Use

Indicated for patients requiring prosthetic rehabilitation via endosseous dental implants. Used as a patient-specific CAD/CAM abutment for cemented or screw-and-cement-retained prostheses.

#### 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.

{4}------------------------------------------------

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) ●

#### 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.

{9}------------------------------------------------

## 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.
