RESUMO

Objetivo: o objetivo do presente estudo foi, através de uma revisão da literatura, identificar e discutir os resultados mecânicos, biológicos e estéticos do uso de materiais cerâmicos como pilares de restaurações unitárias implantossuportadas na região anterior. Material e métodos: a estratégia de busca constituiu-se na procura de estudos in vitro, in vivo e ensaios clínicos na base de dados PubMed, redigidos na língua inglesa, publicados nos últimos cinco anos e que avaliaram o uso de pilares cerâmicos. Os dados coletados (objetivo, material cerâmico avaliado, grupos de comparação, tipo de desfecho e achados principais) foram organizados na forma de tabela, e uma análise descritiva foi realizada. Resultados: a busca identificou 26 artigos, dos quais 17 foram incluídos na análise descritiva. Conclusão: a partir da análise descritiva dos dados obtidos, pôde-se concluir que o uso de materiais cerâmicos na confecção de pilares protéticos se mostra bastante promissor, visto que restaurações preparadas sobre estes pilares apresentaram resultados mecânicos satisfatórios e altas taxas de sucesso durante o acompanhamento clínico, além de possibilitarem um elevado grau de satisfação estética, o que é particularmente importante na região anterior.

ABSTRACT

Objective: the aim of the present study was, through a literature review, to identify and discuss the mechanical, biological and aesthetical results of using ceramic materials as abutments of implant-supported single crowns in the anterior region. Material and methods: the search strategy consisted of looking for in vitro, in vivo and clinical trials studies in the PubMed database, written in English, published in the last 5 years and that evaluated the use of ceramic abutments. The collected data (objectives, evaluated ceramic material, comparison groups, type of outcome and main findings were organized in a table and a descriptive analysis was performed. Results: the search identified 26 articles, of which 17 were included in the descriptive analysis. Conclusion: from the descriptive analysis of the collected data, it can be concluded that the use of ceramic materials in the fabrication of prosthetic abutments is very promising, since restorations prepared over these abutments presented satisfactory mechanical results and high success rates during clinical follow-up, and also generating a high degree of aesthetic satisfaction, which is particularly important in the anterior region.

Key words – Anterior teeth; Ceramic abutments; Fixed implantsupported prosthesis; Single restorations.
