Hex-Lock® Short Abutment and Restorative System
Innovative design helps meet clinical challenges.
The posterior restoration process presents a number of time-consuming challenges for dental practitioners. Limited interocclusal space, reduced visibility, and lengthy preparation procedures undermine efficiency, increasing chairtime. As patients become more educated about implant options, and they become the standard of care, more clinicians are beginning to treatment plan for implants in their practices. As such, dental practitioners are concerned with patient-friendly procedures and products that work within their practice needs.
The Hex-Lock Short Abutment and Restorative System from Zimmer Dental Inc is innovatively designed to help clinicians meet these challenges. From a leading provider of dental oral rehabilitation products, this all-inclusive system promotes simple and immediate posterior restorations, and includes healing caps, snap-on impression caps, analogs, and provisional and waxing copings (Figure 1, Figure 2.)
The Hex-Lock Short Abutment and Restorative System includes the new titanium Hex-Lock Short Abutment and corresponding Short Restorative Components. The Hex-Lock Short Abutment and Restorative System is indicated for both single- and two-stage protocols, and is designed to work seamlessly with Zimmer's highly regarded Tapered Screw-Vent® and Screw-Vent® Implant Systems.
A COMPLETE SYSTEM (1. and 2.) The Hex-Lock Short Abutment and Restorative System includes healing caps, snap-on impression caps, analogs, and provisional and waxing copings.
Hex-Lock Short Abutment's reduced cone height, predetermined margins, and off-the-shelf convenience help to decrease chair and preparation time significantly. Snap-on caps allow for easier abutment-level impression taking, and prefabricated copings facilitate immediate provisionalization and final crown preparation.
Because the Hex-Lock Short Abutment and Restorative System is markedly simple, immediate, and convenient, its use can promote clinician confidence in implant procedures. It uses the same restorative protocol as Zimmer Dental's Hex-Lock Contour Abutment System. In addition, color-coding matches the emergence profiles. For most practitioners, no additional learning curve is required to integrate this system into a practice.
The Hex-Lock Short Abutments are compatible with all Tapered Screw-Vent® Implants and support all of Zimmer Dental's prosthetic platforms. These aligned products and procedures offer the best results for patient satisfaction and clinician assurance.
- The shorter profile (4-mm cone) is specifically designed for the limited interocclusal space of the posterior
- Predetermined margins reduce or eliminate the need for preparations
- Straight, continuous margins around the abutment allow for easy placement in any orientation
Begin by removing the Healing Collar from the implant using the Hex Tool. Seat the Hex-Lock Short Abutment onto the implant; tighten the screw to 30 Ncm with a calibrated prosthetic torch wrench. Verify with x-rays that the abutment is fully seated.
Next, place the Short Impression Cap over the abutment and snap into place. (If modifications to the abutment are needed, the impression cap should not be used.) Syringe the impression material around the impression cap and record a full-arch impression. Align the Short Abutment Analog with the impression cap. Insert the analog into the impression and snap into the impression cap. Send the impression to the laboratory to prepare the final restoration.
Prepare the provisional crown by applying acrylic to the Short Provisional Coping (or use the coping alone). Block out the screw channel and cement the crown, (or cap) in place with provisional cement.
In the laboratory, pour the model in die stone, using soft-tissue material to represent the gingival contours. Place the Short Waxing Coping on the abutment analog in the master cast, using the flat on the analog to align with the flat on the coping.
Seal the margins of the Short Waxing Coping. Wax and cast the coping, using traditional prosthodontic techniques. Apply porcelain to the casting to complete the restoration.
Finally, remove the provisional crown, and clean off remaining cement. Block out the screw channel and cement the final crown.
