OSSEOTITE® External Hex Implant System
The external hexed implant design has historically been the most widely used implant design in implant dentistry.

1. Gold Standard ZR™ (Zero Rotation) is a patented design of machined microstops within the corners of the hex in the abutment. The design reduces horizontal rotation between the implant and abutment. Gold Standard ZR is available on UCLA, GingiHue® Post and Conical abutments.

2. The 12-point double hex, which is machined in the 15º Pre-Angled GingiHue Post, provides rotational positioning in 30º increments on the implant hex.

3. Impression Copings: Pick-Up and Twist Lock™ Transfer Copings are both available in the external hex design, in three EP® (Emergence Profile) diameters and a straight diameter to match the healing abutments. The patented Twist Lock design provides a more accurate transfer of the implant hex compared to other transfer (closed tray) techniques. The unique Twist Lock feature provides a series of undercuts to guide the coping into the impression for stability. As a result, the copings lock into orientation grooves upon clockwise rotation, thereby allowing a tactile sensation of resistance that ensures an accurate hex transfer.

4. Precise Abutment Placement: The ASYST® Abutment Placement Tool provides fingertip control for fast and easy abutment delivery. The patented packaging design makes abutment placement easier because the abutment is delivered sterile from the package directly to the implant site. The abutment and abutment screw are packaged inside the plastic ASYST seating device. The plastic seating device facilitates precise placement of the abutment on the implant, thus reducing chair time. The ASYST Tool is packaged with Standard and Conical abutments.
