title: Improving the fracture resistance of dental ceramic.
abstract: A time-temperature sequence for optimally strengthening dental ceramic by ion exchange was investigated. Stress relaxation occurs at higher temperatures and/or longer times. Improved strenghts are obtained in a reasonable period of time that could be used for clinical application.
