PROVISIONAL RESTORATIVE MATERIAL IN FPD
Provisional restorations play a pivotal role in fixed and removable prosthodontic treatment, acting as a functional and esthetic intermediary until the placement of definitive prostheses. These restorations not only protect prepared teeth and maintain occlusal relationships but also provide an opportunity to evaluate the form, function, and esthetics prior to final cementation. A wide range of materials is available for provisional restorations, including polymethyl methacrylate (PMMA), poly ethyl methacrylate (PEMA), bis-acryl composite resins, and light-cured resins, each with distinct physical and handling properties. The selection of an appropriate material depends on multiple factors such as duration of use, esthetic demands, mechanical strength, and biocompatibility. Recent advancements have introduced CAD/CAM fabricated provisional and nanotechnology-enhanced materials, offering improved performance and predictability. This review aims to provide an in-depth analysis of various provisional restorative materials, highlighting their properties, advantages, limitations, and clinical considerations, thereby guiding clinicians in making informed material choices for optimal patient outcomes.
