Zirconia in fixed prosthesis. A literature review.

Agustín-Panadero R, Román-Rodríguez JL, Ferreiroa A, Solá-Ruíz MF, Fons-Font A - J Clin Exp Dent (2014)

Bottom Line: To carry out a literature review of the behavior of zirconium oxide dental restorations.Both in vivo and in vitro studies into zirconia-based prosthodontic restoration behavior were included.These results provoke uncertainty as to the long-term prognosis for this material in the oral medium.

ABSTRACT

Statement of problem: Evidence is limited on the efficacy of zirconia-based fixed dental prostheses.

Objective: To carry out a literature review of the behavior of zirconium oxide dental restorations.

Material and methods: This literature review searched the Pubmed, Scopus, Medline and Cochrane Library databases using key search words "zirconium oxide," "zirconia," "non-metal restorations," "ceramic oxides," "veneering ceramic," "zirconia-based fixed dental prostheses". Both in vivo and in vitro studies into zirconia-based prosthodontic restoration behavior were included.

Results: Clinical studies have revealed a high rate of fracture for porcelain-veneered zirconia-based restorations that varies between 6% and 15% over a 3- to 5-year period, while for ceramo-metallic restorations the fracture rate ranges between 4 and 10% over ten years. These results provoke uncertainty as to the long-term prognosis for this material in the oral medium. The cause of veneering porcelain fractures is unknown but hypothetically they could be associated with bond failure between the veneer material and the zirconia sub-structure. Key words:Veneering ceramic, zirconia-based ceramic restoration, crown, zirconia, tooth-supported fixed prosthesis.
