Verification jig for implant-supported prostheses: A comparison of standard impressions with verification jigs made of different materials.

Statement Of Problem: Implant verification jigs are routinely used during the fabrication of implant-supported prostheses. The dimensional accuracy of these jigs is unknown.

Purpose: The purposes of this study were to (1) compare the dimensional accuracy of verification jigs with that of conventional impression procedures and (2) measure the dimensional accuracy of 3 resin materials used to fabricate verification jigs.
