A study on the in-vitro wear of the natural tooth structure by opposing zirconia or dental porcelain clinical validity of a zirconia full-coverage crown by comparing zirconia's wear capacity over antagonistic teeth with that of feldspathic dental porcelain. ... J Yu-Seok,L Jae-Whang,C Yeon-...
C, Zirconia crown compressive test. D, Lithium disilicate compressive test. The compression test was conducted using the universal testing machine equipped with a 30-kN load cell. The force was applied via a tungsten carbide pilot punch with a radius of 3.18 mm, targeting the central ...
(2007) reported that the lifetime predictions after 10 years indicate a reduction of 50%, 36%, and 29% in strength for porcelain, alumina, and Y-TZP, respectively. On the other hand, Studart et al. (2007a,b) demonstrated that posterior bridges with zirconia frameworks can exhibit ...

The statistical analyses were performed with the Kaplan-Meier method.One core fracture occurred in Zircad/Zirpress crowns and one metal ceramic crown was lost for root fracture. Chipping fracture of the veneering ceramic was detected in 2 metal-ceramic crowns and in 3 zirconia-based crowns. The...

Furthermore, 75% of anterior zirconia implants failed palato-buccally, due to contact-loading forces on the palatal surface of the maxillary central incisor crown. An exception to this was the Z-Look 3 implants, which fractured bucco-palatally during silicone impression retrieval [21]. ...
