Implant Verification Jig

How to use an implant verification jig 

To ensure that your final screw-retained framework has the optimum passive seat, a verification jig  is recommended. A verification jig is used to verify that the master model is accurate prior to manufacturing the framework. 

​

Place the jig on top of all of the implants in the mouth. Look for any sign of a rock in the frame. Screw in the most distal screw, and look to see if the frame lifts on the other side. Remove the screw and do the same on the most distal implant on the other side. Continue with this procedure until every screw has been tried in and no lifts are seen. 

​

If you find no rocks, the model is accurate to the mouth. If the jig rocks anywhere, section the frame and repute it in the mouth until it seats passively without any rocks. The lab will then modify the master model with the jig, and the next step can begin. 

​

If the jig does not fit the mouth, the model is incorrect. In this case, you must cut the jig and reconnect it in the mouth. Modify the model or make a second verification model.

​

This step will guarantee a properly fitting final frame, as well as avoid the expense and time required to re-solder the connections and begin again by taking a new impression.
