“…Chipping of the veneering ceramic and loss of retention were technical complications also reported for multiple-unit zirconia based FDPs [15][16][17], occurring significantly more often at the zirconia-based FDPs than at metal-ceramics [18]. The more recent clinical studies showed that despite all developments and efforts for the improvement of the veneering procedures of zirconia frameworks, the problem of chipping of the zirconia veneering ceramic has not been eliminated yet [19,20]. Consequently, zirconia-based single crowns should not be considered as the primary treatment option for now, and patients need to be thoroughly informed about current limitations.…”

A systematic review of the survival and complication rates. (2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013) were performed for clinical studies focusing on tooth-supported fixed dental prostheses (FDPs) with a mean follow-up of at least 3 years. This was complimented by an additional hand search and the inclusion of 34 studies from a previous systematic review [1,2]. Survival and complication rates were analyzed using robust Poisson's regression models to obtain summary estimates of 5-year proportions.Results. Sixty-seven studies reporting on 4663 metal-ceramic and 9434 all-ceramic SCs fulfilled the inclusion criteria. Seventeen studies reported on metal-ceramic crowns, and 54 studies reported on all-ceramic crowns. Meta-analysis of the included studies indicated an estimated survival rate of metal-ceramic SCs of 94.7% (95% CI: 94.1-96.9%) after 5 years.This was similar to the estimated 5-year survival rate of leucit or lithium-disilicate reinforced glass ceramic SCs (96.6%; 95% CI: 94.9-96.7%), of glass infiltrated alumina SCs (94.6%; 95% CI: 92.7-96%) and densely sintered alumina and zirconia SCs (96%; 95% CI: 93.8-97.5%; 92.1%; 95% CI: 82.8-95.6%). In contrast, the 5-year survival rates of feldspathic/silica-based 604d e n t a l m a t e r i a l s 3 1 ( 2 0 1 5 ) 603-623were compared feldspathic/silica-based ceramic and zirconia crowns exhibited significantly lower survival rates in the posterior region (p < 0.0001), the other crown types performed similarly. Densely sintered zirconia SCs were more frequently lost due to veneering ceramic fractures than metal-ceramic SCs (p < 0.001), and had significantly more loss of retention (p < 0.001). In total higher 5 year rates of framework fracture were reported for the all-ceramic SCs than for metal-ceramic SCs.Conclusions. Survival rates of most types of all-ceramic SCs were similar to those reported for metal-ceramic SCs, both in anterior and posterior regions. Weaker feldspathic/silica-based ceramics should be limited to applications in the anterior region. Zirconia-based SCs should not be considered as primary option due to their high incidence of technical problems.

“…Results of this study agreed with the findings of several clinical studies. It was numerously reported that chipping was the most frequently encountered clinical failure, although interfacial failures between zirconia cores and ceramic veneers were still encountered [2][3][4][27][28][29] . In the present study, the authors did not investigate the effects of aging by thermocycling on bond strength, which would make the experimental condition more analogous to the oral environment.…”

This study investigated the effect of digital veneering system (DVS) on strengthening the bond between a zirconia core and ceramic veneer. Specimens for Groups 1 (negative control), 2 (positive control), 3, and 4 used conventional porcelain veneering technique on untreated, sandblasted, coloring agent-treated, and modifier-treated zirconia cores respectively. Group 5 used DVS, where glass ceramic veneers -produced by computer-aided milling-were fused to zirconia cores. Microtensile bond strengths (MTBS) at the interface were measured. MTBS results of Groups 1 to 5, expressed in mean (standard deviation), were 28.1 (7.3), 27.8 (6.3), 30.0 (10.2), 32.9 (8.1), and 37.8 (8.1) MPa. The DVS group had significantly higher MTBS than the negative and positive controls (p<0.05). Results showed that DVS enhanced the bond strength between zirconia core and ceramic veneer, indicating that this system could reduce adhesive failure-related complications that frequently occur at the zirconia core-veneer interface.

“…Leucite, for example, displays an unsatisfactory failure which is revealed in a high incidence of fracture or chipping [3,8,12,14,15,25,28,[30][31][32][33]. The strong increase of chipping with time, as discussed in reference [33] for glass-ceramic veneers on ZrO 2 substrate indicates that many parameter and fatigue mechanisms contribute to eventual failure.…”

A multi technique study of a new lithium disilicate glass-ceramic spray-coated on ZrO 2 2 2 substrate for dental restoration https://doi.org/10.1515/bglass-2017-0004 Received May 05, 2017 revised Jul 07, 2017; accepted Aug 09, 2017 Abstract: An alkali niobate-silicate veneer ceramic for ZrO 2 -based dental restoration was developed and characterized for its physical properties and structure. The properties were adjusted for dental applications. The new lithium disilicate glass-ceramic VBK (sold as cerafusion or LiSi) can easily be applied by spray coating to any individually formed ZrO 2 -matrix and needs only one final tempering treatment. The surface of the glass-ceramic is very smooth. The color of the already translucent glass-ceramic can be adjusted to that of individual natural teeth. The structure of the glass-ceramic was studied by XRD and Raman spectroscopy as a function of heat-treatment and of spatial variations within the material and at its interfaces. ToF SIMS, SEM and thermal analysis techniques were applied to investigate the crystallization behavior and surface-interface reactions. XRD and Raman spectroscopy identified different crystalline phases in the amorphous glass matrix including Li 2 Si 2 O 5 , Li 2 SiO 3 , NaxLi (1−x) NbO 3 and Na 3 NbO 4 . The Raman spectrum of the amorphous matrix is dominated by the vibrational activity of the highly polarizable niobate units with a prominent feature at 865 cm −1 , assigned to Nb-O stretching in NbO 6 octahedra, which have non-bridging oxygen atoms and are connected to the silicate matrix rather than to other niobate polyhedra.
