Resumo(s)
A endocrown representa uma alternativa restauradora conservadora para dentes tratados endodonticamente, especialmente na presença de ampla perda estrutural coronária. Esta dissertação teve como objetivo avaliar, através de uma revisão integrativa da literatura, a eficácia clínica, biomecânica e estética da técnica de endocrown em comparação a outras abordagens restauradoras convencionais, como as coroas suportadas por espigões intrarradiculares. A pesquisa bibliográfica foi realizada nas bases de dados PubMed/MEDLINE, ScienceDirect e Scopus. Foram utilizados os filtros de artigos completos disponíveis online e o limite temporal de 2014 a 2025, assim como foram aplicados critérios de elegibilidade pré-estabelecidos. Foram selecionados estudos clínicos, laboratoriais e comparativos, com foco em resistência à fratura, adaptação marginal, escolha de materiais restauradores e implicações funcionais. Os resultados revelam que as endocrowns confecionadas com cerâmicas vítreas, como dissilicato de lítio e silicato de lítio reforçado com zircônia, apresentam desempenho clínico satisfatório e resistência à fratura comparável às técnicas convencionais, com vantagens em termos de preservação da estrutura dentária e simplicidade técnica. Apesar dos resultados promissores, a literatura carece de ensaios clínicos longitudinais em dentes anteriores, o que limita a extrapolação dos dados para a prática clínica. Conclui-se que, quando corretamente indicadas e executadas, as endocrowns configuram-se como uma opção restauradora viável, funcional e esteticamente previsível.
The endocrown represents a conservative restorative alternative for endodontically treated teeth, especially in the presence of extensive coronal structural loss. This dissertation aimed to evaluate, through an integrative literature review, the clinical, biomechanical, and esthetic efficacy of the endocrown technique compared to other conventional restorative approaches, such as post-supported crowns. The literature search was conducted in the PubMed/MEDLINE, ScienceDirect, and Scopus databases. Filters for full-text articles available online were used, and the time limit from 2014 to 2025 was applied, as well as pre-established eligibility criteria. Clinical, laboratory, and comparative studies were selected, focusing on fracture resistance, marginal adaptation, choice of restorative materials, and functional implications. The results reveal that endocrowns made with glass-ceramics, such as lithium disilicate and zirconia-reinforced lithium silicate, present satisfactory clinical performance and fracture resistance comparable to conventional techniques, with advantages in terms of tooth structure preservation and technical simplicity. Despite the promising results, the literature lacks longitudinal clinical trials in anterior teeth, which limits the extrapolation of the data to clinical practice. It is concluded that, when correctly indicated and executed, endocrowns are a viable, functional, and aesthetically predictable restorative option.
