Intended Use

The Straumann CARES® TAN abutments are indicated for single tooth replacement and multiple tooth restorations. The prosthetic restoration can be cemented or directly veneered/ screw-retained. Prosthetic components connected to the implant are intended for use as an aid in prosthetic rehabilitation.

Device Story

Straumann CARES TAN Abutments are customized dental abutments for endosseous dental implants. Input data consists of either traditional wax-up abutment scans or intraoral scans. Design is performed using Straumann CARES Visual CAD software, which enforces material-specific design limits (angulation, thickness, emergence). Design data is transmitted to a Straumann milling center for fabrication. The device is used by dental professionals in clinical settings to support crowns, bridges, or overdentures. The abutments can be cemented or directly veneered. The device benefits patients by providing a customized, functional, and esthetic prosthetic interface for dental implants.

Clinical Evidence

Bench testing only. Evidence includes dynamic fatigue testing per ISO 14801, veneer testing per ISO 9693-1, and corrosion resistance testing per ISO 10271. Biocompatibility testing includes cytotoxicity (ISO 10993-5) and chemical analysis (ISO 10993-18).

Technological Characteristics

Material: Titanium-6aluminum-7niobium alloy (TAN) per ISO 5832-11. Design: CAD/CAM customized. Platforms: Bone Level (NC, RC) and Tissue Level (RN, WN). Manufacturing: Milling center fabrication based on software-controlled design limits. Connectivity: Digital design data transfer.

Indications for Use

Indicated for single tooth replacement and multiple tooth restorations in patients requiring prosthetic rehabilitation via dental implants.

Regulatory Classification

Identification

An endosseous dental implant abutment is a premanufactured prosthetic component directly connected to the endosseous dental implant and is intended for use as an aid in prosthetic rehabilitation.

Special Controls

*Classification.* Class II (special controls). The guidance document entitled “Class II Special Controls Guidance Document: Root-Form Endosseous Dental Implants and Endosseous Dental Implant Abutments” will serve as the special control.
