The Zfx Abutments are intended to be used in conjunction with endosseous dental implants in the maxillary or mandbular arch to provide support for prosthetic restorations. All digitally designed custom abutments or superstructures and/or hybrid abutment crowns for use with Zfx TiBase or Pre-Milled Blank Abutments are intended to be sent to a Zfx validated milling center for manufacture. The Zfx TiBase abutments for the 03.25 mm Certain implant bodies, and 03.1 mm Eztetic implant bodies are indicated for maxillary lateral and mandibular central/lateral incisors only.

The subject device, Zfx Abutments, consists of two abutment types, a TiBase and a Pre-milled Abutment Blank, with corresponding retaining screws. Zfx Abutments are offered in a variety of connections compatible with ZimVie dental implants. All abutments and screws are provided non-sterile. TiBase Abutments: Subject device TiBases are two-piece abutments. The pre-manufactured titanium base component is the apical part. The coronal part of the two-piece abutment is a CAD/CAM designed and manufactured superstructure. The subject device TiBase abutments are available in hexed/engaging and non-hexed/nonengaging configurations. The engaging TiBase abutments are intended for single and multi-unit restorations and the non-engaging TiBases are intended for multi-unit restorations. The superstructure is intended to be manufactured at a Zfx validated milling center. Pre-milled Abutment Blanks: The Pre-milled Abutment Blank is a cylindrical titanium alloy abutment designed for patient-specific abutment fabrication with CAD/CAM technology. The patient-specific abutment milled from a Pre-milled Abutment Blank is secured directly to the implant using a retaining screw. Pre-milled Abutment Blanks are available in an engaging/hexed design only for single-unit and multi-unit restorations. Retaining Screws: Corresponding retaining screws are packaged with the abutment and replacement screws are available individually. All screws are compatible with the corresponding ZimVie dental implants. Material Composition: All subject device abutments are made of titanium alloy Ti-6Al-4V ELI conforming to ASTM F136. Screws are made of either titanium alloy Ti-6A1-4V ELI conforming to ASTM F136, or Gold-Tite® screws with stainless steel conforming to ASTM F138. Gold-Tite screws have a gold-plating conforming to ASTM B488 and ASTM B571. Zirconia superstructures for use with the TiBase Abutments are made of zirconia conforming to ISO 13356.
