Super Porcelain EX-3 ™ (EX-3 ™) is a high quality metal framework ceramic developed on the basis of Kuraray Noritake Dental's extensive knowledge of ceramic technology. Its exceptional characteristics are made possible thanks to its fine particle size. EX-3 ™ is superior to other dental ceramics because its coefficient of thermal expansion remains stable during repeated firings. Therefore, in the construction of a multi-element bridge, each unit can be stratified in a more or less complex way even with repeated firings of the entire bridge, but without the risk of fractures. It is compatible with precious, semi-precious, non-precious and non-silver alloys for metal-ceramic prostheses. Its fluorescence is ideal and highly resistant to unwanted color effects (greening), induced by silver.
