Abstract
All-ceramic crowns have been extensively used in prosthodontics in recent years for their superior gingival response and esthetic quality, while achieving similar marginal accuracies when compared to traditional metal-based restorations. CAD/CAM, which is computer aided design/computer aided manufacturing technology, offers a superior advantage of time-saving procedures and precise dimensions, which give more control over the products of this type of technique. The use of toughened ceramics such as yttrium-stabilized zirconium offers a more fracture-resistant application of all-ceramic crowns to the posterior region without sacrificing esthetic qualities. The use of press-on ceramic over the zirconium core combines the high bond strength and superior interface quality achieved using press-on ceramics with the superior esthetics obtained by using layering ceramics. A laboratory research to compare the fracture strength between monolithic lithium di-silicate pressed crowns and the bi-layered zirconium based pressed crowns with two different coping design will be discussed and presented.
