Background and Aim: Water sorption of provisional crown materials decreases their mechanical properties and longevity, depending on the material type. This study aimed to compare the water sorption of three provisional crown materials in vitro.
Materials and Methods: In this in vitro experimental study, 14 disc-shaped specimens measuring 1 x 15 mm were fabricated from Telio CAD polymethyl methacrylate (PMMA) computer-aided design-computer-aided manufacturing (CAD-CAM) block (Ivoclar Vivadent), self-cure PMMA acrylic resin (Tempron GC), and ProviTemp K acrylic-based composite resin (Provi Temp K). The specimens were randomly coded and their weight (with 0.0001 g accuracy) and volume (with 0.001 mm accuracy) were measured. The water sorption of the specimens was calculated after 7 and 30 days. One-way ANOVA was applied for data analysis (α=0.05).
Results: On day 7, the highest water sorption was noted in Bisco acrylic-based composite resin (mean: 22.84±5.04 µg/mm3) and the lowest water sorption was recorded in PMMA CAD-CAM block (mean: 14.22±3.23 µg/mm3) (P=0.023). At 30 days, the highest water sorption was recorded in Tempron GC self-cure acrylic resin (mean: 48.53±18.44 µg/mm3) and the lowest water sorption was noted in PMMA CAD-CAM block (mean: 40.24±5.33 µg/mm3) (P=0.002).
Conclusion: The water sorption of Bisco acrylic-based composite resin and Tempron GC self-cure acrylic resin was very high in the short-term. However, after 30 days, the water sorption of Bisco acrylic-based composite resin and PMMA CAD-CAM block was the same. It appears that all three tested materials can provide acceptable clinical performance for the fabrication of provisional restorations.
