Dynamic Response of Human Wisdom Teeth and Temporary Fillers

Dynamic property of materials has been very important for material researches, especially in high strength material disciplines. However, because of the improvements in material manufacturing processes, more and more composites and polymers have replaced high strength materials. Composite and polymer materials were best known for their light weight, and good mechanical strength. Now, they have been widely used in tooth filling materials. In this research, different kinds of tooth filling composites were examined using Split Hopkinson Pressure Bar (SHPB). High strain rate response of human wisdom teeth were also examined using SHPB. The dynamic properties of fillers and human wisdom teeth between 500 and 2,000 s−1 were examined. The proper mixing percentages of filler materials were tested accordingly. The results could be very useful for future dentures or filler materials development.
