The role and function of provisional restorations has changed significantly in recent years. The reasons include the improvement of material properties and the CAD/ CAM production option using polymer blanks, which are offered by various manufacturers. Besides their classic indications in crown and bridge prosthodontics, provisional restorations are now used for soft-tissue management, preparation and adaptation in complex restorations that include changes in vertical relations, and as mock-ups in esthetic dentistry.
