Verification Jig

Before manufacturing the prosthetic framework for multiple dental implants, it’s important that periodontists ensure that the framework has the optimal passive seat. To do this, a verification jig is often used. This ensures that the master model is precise before the framework is created. A verification jig mimics the fit of the final restoration framework so the model accuracy can be verified to confirm that the end restoration fits perfectly. The jig is made of temporary cylinders that are joined together with a stiff resinous material and often, rods or sturdy wires. Then, the jig is placed over all of the dental implants in the patient’s mouth; an unstable frame means that the screws need to be adjusted on either side to prevent movement of the jig. The jig can be used for the final framework once all rocking or movement in the mouth has ceased.
