What is a ‘pressed ceramic’ restoration? How is this different from feldspathic porcelain? I keep hearing lecturers voice their support for one of these kinds of porcelain but I do not understand what is so important? Is one more aesthetic than the other? Is one stronger than the other? Are there specific indications for each of these different kinds of porcelain? Should I be choosing one of these for certain kinds of ceramic restorations? Would my lab know about the difference?
