While this review of zirconium restoration included 27 studies, only 5 were RCTs. Furthermore only 4 studies had more than 5 years follow up. Ten studies included fewer than 20 restorations, so while good survival data was presented, the results should be viewed with caution.

This ADA-EBD critical summary has looks at a 2012 systematic review by Wang et al. The aim of the review was to evaluate the clinical fracture incidence of tooth-supported all-ceramic crowns according to restored tooth type. The appraiser considered the reviews search strategy to be thorough but noted that the studies were not assessed for [read the full story…]
Some degree of tooth wear is a result of normal tooth-to-tooth contact. Some restorations have different wear characteristics and have been shown to produce accelerated wear. The aim of this review was to assess tooth wear against ceramic crowns in posterior region both in vitro and in vivo. Searching was restricted to the Medline database. [read the full story…]
The aim of this study was to evaluate the clinical outcome of shrinkage-free ZrSiO4-ceramic full- coverage crowns on premolars and molars in comparison with conventional gold crowns over a 5-year period. Invited patents who required posterior crowns were randomised to receive either a shrinkage-free ZrSiO4-ceramic crown (test group) or a gold crown (control group). The [read the full story…]
The use of ceramic materials to restoring posterior teeth has been increasing since the 1990s, and in 2003 a Cochrane review by Hayashi and Yeung was published . The aim of this review was to update that 2003 review by evaluating the clinical effectiveness of ceramic inlays including all articles published since 2002. The PubMed, [read the full story…]
Improvements in dental ceramic materials in the past decade has led to the increasing use of all ceramic crowns on posterior teeth. The aim of this study was to evaluate the clinical fracture incidence of tooth-supported all-ceramic crowns according to restored tooth type. The authors searched the Medline/PubMed, Embase, the Cochrane Library, the Chinese Biomedical [read the full story…]
