[Orientation studies on the stability of metal-ceramic crowns made from new materials]

Materials for metal-ceramic crowns have been developed further in the last few years and the use of this type of crown increases steadily. Numerous investigations concern themselves with binding and other properties of this material as well as with its favourable moulding capacity. The present investigation is oriented towards establishing the order of magnitude and limits of confidence of fracture resistance which has to be reckoned with when using a metal-ceramic crown in the mouth.
