The Zimmer Dental Hex-Lock Prepared Straight Abutment is used as a terminal or intermediate abutment for a cemented prosthesis. The Zimmer Dental Hex-Lock Prepared Angled Abutment is used as a terminal or intermediate abutment for a cemented prosthesis where the angle needs to be offset by 17°. Either abutment can be used for a single or multiple-unit restoration.
The 'Prepared' Abutment is a titanium alloy post with a tapered cone, predefined margin and varying cuff heights. The abutment engages the internal hex of the implant and is secured with a separate retaining screw. The cone of the abutment is 5.5mm in height, with 8° of taper (4° per side). The height of the cuff is lower on the buccal aspect, higher on the lingual. A vertical groove is located on the lingual aspect of the cone.
