Verification Jigs, the step not to skip when restoring multiple implants

Updated: Feb 5

The regular use of titanium and zirconia has presented an obvious problem to any clinician employing splinted implant prosthodontics. Cad Cam technology can help us to manufacture components that fit the cast perfectly, however the cast is not the ultimate recipient of the prosthetics, the patient is. In order to develop a more accurate master cast, we adjust our procedures from impression to cast fabrication to minimize imperfections. After all that is done, we need a way of checking the accuracy prior to committing time and resources to manufacture the restoration.


After the cast is made and we have employed all possible techniques to attain accuracy we make a verification jig to check our accuracy at this phase. There are many varations availble to accomplish this including GC resin and type IV gypsum. The technique I like to use is a 2 phase technique using UDMA resin (light cured tray material) and GC resin to create a rigid non-compromisable structure that is dimensionally stable yet still correctable. Made on the cast and tried in intraorally to verify passive fit. If a single implant is out of place the non-engaging component is sectioned out and an engaging component is attached in its place. This newly connected assembly is then used to alter and correct the cast.
