Why is a good provisional important? Provisional restorations are used as interim prosthesis for inlays, onlays, crowns and bridges. Their primary functions are to maintain the position of prepared teeth, protect preparation margins, seal prepared teeth and insulate them against thermal changes. Additionally, they can be used to establish proper vertical dimension and anterior guidance, aid in diagnosis and treatment planning, retain orthodontically moved teeth and act as prototypes for final restorations.
