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.

- Intended Use:
The Zimmer Dental Hex-Lock Prepared Abutment, Straight is used as a terminal or intermediate abutment for a cemented prosthesis. The Zimmer Dental Hex-Lock Prepared Abutment. Angled 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.
- Intended Use:
-
- Device Comparison:
The new straight & angled abutments and the predicate abutment have an identical internal hex friction-fit implant interface. The new device will be affixed to the implant in the same manner as the predicate. The new straight abutment will use the same screw as the predicate. The device modification is a dimensional change. The materials, general structure, and function in the endosseous implant system remains the same as the predicate device.
- Device Comparison:
The new abutment differs from the predicate by providing a prepared margin and cone shape. The end user can make additional modifications if desired, but the new abutment can be used "as is." The taper on the cone of the new abutment is 4 degrees. The new abutment also adds two coronal grooves for crown retention. The cone of the new abutment has a non-circular cross section for anti-rotation compared to a flat side on the predicate design. A vertical groove has been added on the linqual aspect for additional anti-rotation. This feature was added to create better interaction with mating plastic caps. The shape of the emergence profile on the new abutment varies from the predicate. The new abutment has a contoured cuff that rises from the implant platform and flares out to a wider emergence profile diameter.
The predicate is an un-prepared abutment that the dental lab contours specifically for the patient's needs. The predicate abutment has no predefined margin or cone shape. The end user grinds the titanium to define the desired margin and determine the cone geometry. The predicate abutment features straight walls. The end user defines the angle of the cone in their preparation. The predicate's circular grooves are height markings at 1mm intervals to aid in marking the abutment for preparation. The grooves on the predicate are typically removed in the preparation process and are not designed for crown retention. In addition, the predicate design rises straight off the implant platform with no flare.
