Marginal integrity of provisional resin restoration materials: A review of the literature
Marginal adaptation of provisional restorations is a critical property of these treatments. It is a function of the chemical composition, setting method, and aging procedures. Interim materials include polymethyl methacrylate (PMMA), polyvinyl ethyl methacrylate (PVEMA), Bis-phenol A glycidyl methacrylate (Bis-GMA) composites, and urethane dimethacrylate (UDMA) composites. This review summarizes and compares their marginal fit in the light of the potential disrupting factors and the underlying mechanisms. All these materials fail in moderate- or long-term durations under oral stresses and water sorption, and should be rapidly replaced by permanent restorations before damaging teeth and adjacent tissues.
