All-ceramic dentures with a framework made of a ceramized zirconium oxide

摘要

The invention relates to a fully ceramic tooth replacement with a frame made of a frame material which is constructed from cer-stabilised zircon oxide (Ce-ZrO2) with up to 25 wt. % aluminium oxide (Al2O3) in relation to the ZrO2 content and an infiltration glass content in the frame of 0-40 vol. % in relation to the volume of the frame, in addition to a facing ceramic which matches the frame material. The invention relates to the use of cer-stabilised ZrO2 for producing frame materials, which can be used in dental restoration.
