Abstract(s)
De forma a completar as necessidades estéticas, que são cada vez mais exigidas pela
sociedade, as cerâmicas dentárias têm apresentado rápida evolução com o intuito de
melhorar as suas propriedades físicas e mecânicas, como também óticas. O
desenvolvimento de novos materiais permitiu a aplicação e o progresso dos sistemas
totalmente cerâmicos utilizados na área da medicina dentária.
Pelas suas características estéticas relativamente aos sistemas metalocerâmicos,
rapidamente os sistemas totalmente cerâmicos ocuparam o seu lugar no mercado,
levando à atenção de médicos dentistas, como dos próprios pacientes. Dentro destes
sistemas totalmente cerâmicos, encontra-se a cerâmica reforçada com dissilicato de
lítio.
Esta revisão narrativa da literatura teve como objetivo descrever as características da
cerâmica dissilicato de lítio de forma a tornar possível compreender em que situações
clinicas poderá ser utilizada, bem como, de que forma é possível otimizar os processos
laboratoriais. Para tal, foram utilizadas várias bases de dados, Pubmed, Scielo, JADA, e
Science Direct, utilizando como palavras-chave: “Ceramic”, “Dental Ceramic”
“Porcelain”, “Lithium Dissilicate”; “IPS e.max”; “IPS Empress II”.
A cerâmica de dissilicato de lítio tem demonstrado a médio prazo um bom
comportamento mecânico e estético durante a sua utilização clinica (onlays, coroas
unitárias, pontes fixas) desde que adequadamente seleccionada em relação às
necessidades impostas pela situação clínica a realizar.
Sendo assim, a cerâmica dissilicato de lítio apresenta-se como uma opção viável na
restauração dentária fixa, no entanto, o seu desempenho encontra-se condicionado pela
correta execução laboratorial e clínica.
In order to complete the aesthetic needs that are increasingly demanded by society, dental ceramics have shown a fast development in order to improve their physical, mechanical, and optic properties. The development of new materials allowed the application and progress of fully ceramic systems used in the field of dentistry. For its aesthetic characteristics in relation to ceramic metal systems, fully ceramic systems quickly occupied its place in the market, leading the attention of dentists, and also from the patients. In these ceramic systems, we can find the with lithium disilicate ceramic system. This narrative literature review aimed to describe the characteristics of lithium disilicate ceramics, in order to understand in which clinical situations it can be used and how the laboratory process could be optimized. For this, they were used several databases, Pubmed, Scielo, JADA, and Science Direct, using as keywords: "Ceramic", "Dental Ceramic" "Porcelain", "Lithium Disilicate"; "IPS e.max"; "IPS Empress II." The lithium disilicate ceramic has demonstrated at medium term a good mechanical and aesthetic behavior during clinical use (onlays, single crowns, fixed bridges), if properly selected to the needs imposed by the clinical situation to perform. Thus, the lithium disilicate ceramics is presented as a viable option in the fixed dental restoration, however, its performance is conditioned by correct laboratory and clinical execution.
