Abstract
In case of Implant superstructure, we pay attention to the crown contour, occlusal form, and many points.
They will be provided by the provisional restoration. The provisional restoration is generally used by acute cured resin. But the resin isn't good for long term use in Implant prostheses. Then metal provisional restoration that is occlusal metal with sandblasting is useful for observation of mandibular movement.
We report that occlusal form and contacts of Implant superstructure is decided by using the metal provisional restoration in observation.
