Fixed prosthodontics provisional materials: making the right selection.

Clinicians have many choices when selecting an appropriate material for interim restorations for both single crowns and multi-units. Interim restorations serve as a diagnostic as well as biologic and biomechanical component of fixed prosthodontics treatment; in the anterior, they are also important in evaluating the esthetics for the definitive restoration. Factors to be considered when choosing provisional materials are physical properties, handling characteristics, patient response to the appearance of the interim restoration, durability of the restoration, and the cost of the material. Practitioners should, therefore, base their choice on the clinical needs for each situation.
