title: Short-term stress-relaxation behavior of nonmetallic restoratives.
abstract: The rheological behavior of five nonmetallic dental materials was studied. Short-term stress relaxation was found to be strongly dependent on time and temperature. Relaxation behavior of the test materials conformed well to simple mathematical models.
