Device Story

TruAbutment DS and TruBase are patient-specific dental abutments; connect to endosseous dental implants to support prosthetic restorations (crowns/copings). TruAbutment DS is a single-piece CAD/CAM abutment; TruBase is a two-piece system consisting of a titanium base and a CAD/CAM-designed zirconia superstructure. Inputs include patient intra-oral data; processed via CAD/CAM software to design custom abutment geometry; manufactured at TruAbutment-validated milling centers. Used in dental clinics by authorized healthcare providers. Output is a custom abutment providing mechanical support for final prosthesis. Benefits include functional and esthetic rehabilitation of edentulous sites. TruBase requires extra-oral cementation of superstructure to titanium base followed by end-user steam sterilization.

Clinical Evidence

Bench testing only. Includes fatigue testing per ISO 14801:2016 on worst-case constructs. Dimensional analysis and reverse engineering confirmed compatibility with OEM implant platforms. Sterilization validation performed per ISO 17665-1/2 and ANSI/AAMI ST79. Biocompatibility leveraged from reference devices.

Technological Characteristics

Materials: Titanium alloy Ti-6Al-4V ELI (ASTM F136). TruBase uses InCoris Zi (ZrO2) for superstructures. Design: CAD/CAM machined patient-specific abutments. Connection: Internal implant interfaces (conical, tri-channel, TorcFit, CrossFit). Sterilization: Non-sterile, requires end-user moist steam sterilization. Connectivity: CAD/CAM digital workflow.

Indications for Use

Indicated for patients requiring prosthetic rehabilitation via endosseous dental implants. TruAbutment DS is for patient-specific CAD/CAM abutments; TruBase is for screw-retained single tooth or cement-retained single tooth and bridge restorations. Compatible with specific MIS, Neodent, Nobel Biocare, and Straumann implant systems.

#### 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.

| Design Parameter | Design Limit |
|----------------------------------------------------------------------------------------------------------|--------------|
| Minimum and Maximum abutment angle(°) | 0 ~ 25 |
| Minimum and Maximum cuff height(mm) | 0.5 ~ 6.0 |
| Minimum and Maximum diameter at abutment/implant interface(Ø,mm) | 3.8 ~ 8.0 |
| Minimum thickness(mm) | 0.4 |
| Minimum and Maximum length of abutment post<br>(length above the abutment collar / gingival height) (mm) | 4.0 ~ 7.0 |

Design Limitation for TruAbutment DS

#### TruBase

TruBase 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. The system also includes a TruBase screw for fixation to the implant body.

TruBase 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 (MIS C1 Narrow Platform

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.
