Aim: The purpose of this study was to compare and evaluate the flexural strength and color stability of three commercially available temporizing resins.
Materials and Methodology: Bar type specimens (65*10*3mm) and square type specimens (10*10*1mm) were fabricated of each material according to the manufacturer’s instructions. A total of 60 samples were selected out of which, 20 samples were fabricated using DPI conventional heat cure resin, 20 samples using 3M ESPE Protemp 4 and the other 20 samples with polymer resin using 3D printer. The specimens were stored in artificial saliva at 37 degrees for 3 months. During this period, specimens were placed in thermocycler for a minimum of 2500 cycles. 10 samples from each group were tested for flexural strength using Universal testing machine and the remaining 10 samples were tested for color stability using spectrophotometer. Comparison of the flexural strength and color stability between 3 types of resins was made.
Results: PROTEMP has the highest flexural strength and color stability when compared with DPI and the 3D Printing materials
Conclusion: Among the three materials compared, bis-acryl composite resin (Protemp-4) can be considered as the best material for long term provisionalization, as it exhibited greater flexural strength. Bis-acryl composite resin (protemp-4) is the most color stable provisional restorative material followed by polymethyl methacrylate (DPI) and 3D printing resin.
