Sucesso clínico de coroas totais cerâmicas obtidas em dissilicato de lítio pelo sistema CAD/CAM: Revisão de Literatura

Abstract

CAD/CAM systems have great prominence in dentistry, and have been widely used in offices and laboratories. With the advancement of technology, it is important to know the clinical outcome of the crowns obtained by the system, in terms of longevity and clinical complications of complete crowns made of lithium disilicate. An analysis was carried out on the clinical success of all-ceramic crowns obtained in lithium disilicate using the CAD/CAM system. Thus, a literature review of prospective studies extracted from the PUBMED database was carried out with a time restriction of analysis from 2010 to 2022, in order to analyze the success rate, complications, and sample number of crowns of lithium disilicate ceramics manufactured by CAD\CAM system. The literature survey with the referred database was carried out through the search of predetermined meshtermes, namely: "prospective studies", "cad/cam", "lithium disililicates" and "tooth crown", and, as a criterion of exclusion, the expressions “partial crowns”, “onlay”, “inlay”, “zirconia”, “leucite” and “fedspathic”. In all, 711 crowns were analyzed, whose success rate was on average 87,5%, survival rate of 90,2% and failure rate of 12,5%, considering the lithium disilicate restorations produced by the CAD\ CAD system.
