Provisional restorations are of a great significance in fixed prosthodontic rehabilitation, particularly in case long-term treatment is needed before final prosthetics. The restorations are also important from the point of view of diagnosis and treatment plan assessment so they should be similar to the final constructions in their shape and function. Provisional restorations quite often need alterations and adjustment to the new requirements, so it’s important to comprehend the compositional properties of the base and repair materials to make a reliable bond between them. Thus, interim treatment should meet a number of requirements such as biocompatibility, marginal adaptation, strength and longevity. The purpose of this review is to discuss fabrication technology of provisional restorations, possible failure and complications, the ways to correct them as well as the aspects of relining provisional restoration.Provisional restorations are of a great significance in fixed prosthodontic rehabilitation, particularly in case long-term treatment is needed before final prosthetics.
