CASTRO-AGUILAR, Enrique Gabriel; MATTA-MORALES, Carlos Octavio  and  ORELLANA-VALDIVIESO, Oscar. Current considerations in the use of free metal single crowns in the posterior area. Rev. Estomatol. Herediana [online]. 2014, vol.24, n.4, pp.278-286. ISSN 1019-4355.

Currently developing new metal-free systems for the fabrication of prosthetic restorations that meet high functional expectations, biocompatibility and aesthetics. However despite the innovation of new materials and technological advances in the development process, it has been questioned the mechanical behavior of single crowns in the posterior area related fractures of the veneering ceramic, to improve these defects, are currently proposing solutions such as making anatomical crowns and translucency monolithic crowns with ceramic lithium disilicate and zirconia This article aims to conduct a review of current considerations in the use of metal free single crowns in the posterior area.

Keywords : Dental crowns; ceramics; dental aesthetics.
