This technology review looked at the effectiveness of crowns on root treated teeth. 3 systematic reviews and 4 non-randomised studies were included. They found that the short term survival with crowns or direct fillings is comparable but long term root canal treated teeth may have better survival.

This review found a significantly higher mean survival for implant supported crowns (97%) compared with Intentionally replanted (IR) teeth (88%). Evidence for IR teeth was limited, being heterogeneous, old and potential suffering from publication bias.

This review of tooth preparation for crowns focuses mainly on the total occlusal convergence angle (TOC). The traditionally recommended 2-4 degree TOC was seen to be unachievable in the clinical situation.

This new critical summary from the ADA-EBD Center for evidence-based dentistry looks at a 2012 review from Pjetursson et al which set out to assess and compare the 5- and 10-year survival of different types of tooth-supported and implant-supported fixed dental prostheses (FDPs) and single crowns (SCs), and to describe the incidence of biological and [read the full story…]
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…]
Crowning of teeth has been carried out for many years in order to replace damaged/diseased tooth structure or to improve aesthetics. Increasing patient demand has helped lead developments in ceramic technology and zirconium is one of the new materials in this field. The aim of this study was to compare the clinical survival rates of [read the full story…]
The aim of this review was to assess the effectiveness of short (<10 mm) implants supporting single crowns in the posterior region and its potential risk factors. A wide range of databases were searched (PubMed-Medline, Web of Science, Cochrane Library, Proquest- Dissertations and Thesis, Lilacs, Ebsco-Dentistry and Oral Sciences Source, Scirus, Embase, Scopus and Journal [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 placement of prosthetic restoration finish line is the subject of much interest and debate. The aim of this review was to assess the effect of prosthetic margin placement on caries susceptibility of abutment teeth Searches were conducted in PubMed, Embase, Google Scholar, Cochrane Central Register of Database of Systematic reviews, Cochrane Central Register of [read the full story…]
