Abstract(s)
A substituição de dentes por implantes dentários é amplamente utilizada na odontologia. O titânio é valorizado por sua biocompatibilidade, resistência mecânica e à corrosão, adequadas para suportar cargas funcionais a longo prazo. Recentemente, com o avanço tecnológico e a redução do uso de metais, materiais cerâmicos, como a zircónia, têm-se destacado como alternativas. A zircónia, além de sua alta longevidade e desempenho em abutments, proporciona benefícios estéticos, especialmente em áreas com mucosa peri-implantar fina, devido à sua coloração branca que melhora a aparência da mucosa em comparação com abutments metálicos.
Objetivo: Compreender se a zircónia utilizada como interface entre coroa e implante apresenta melhores resultados em comparação ao titânio na reação biológica nos tecidos peri-implantares. Serão avaliados diferentes parâmetros biológicos, como a profundidade de sondagem, o sangramento gengival, a perda óssea marginal e a recessão gengival, nos vários estudos para perceber qual irá ter condições biológicas mais favoráveis.
Materiais e métodos: Pesquisa e análise de artigos científicos presentes nas bases de dados online PubMed, Biblioteca do Conhecimento Online (B-On) e Cochrane Library.
Resultados: Considerando uma pesquisa sistemática em que foram definidos claramente os critérios de inclusão e exclusão, foi possível identificar qual material para abutment implantar apresenta o melhor comportamento biológico peri-implantar. Foram identificados 9 artigos que relatam os resultados desta investigação.
Conclusão: Podemos deduzir que os estudos mais recentes não fornecem uma indicação clara, no que diz respeito à reação biológica dos tecidos peri-implantares, sobre qual material é mais adequado. Podemos concluir que a zircónia é uma alternativa válida ao titânio para a criação de abutments.
The replacement of teeth with dental implants is widely used in dentistry. Titanium is valued for its biocompatibility, mechanical and corrosion resistance, suitable for supporting long-term functional loads. Recently, with technological advances and the reduction in the use of metals, ceramic materials such as zirconia have been highlighted as alternatives. In addition to its high longevity and performance in abutments, zirconia provides aesthetic benefits, especially in areas with thin peri-implant mucosa, due to its white colour which improves the appearance of the mucosa compared to metal abutments. Objective: To understand whether zirconia used as an interface between crown and implant has better results compared to titanium in terms of biological reaction in peri-implant tissues. Different biological parameters such as probing depth, gingival bleeding, marginal bone loss and gingival recession will be assessed in the various studies to see which one will have more favourable biological conditions. Materials and methods: Search and analysis of scientific articles in the online databases PubMed, Online Knowledge Library (B-On) and Cochrane Library. Results: Considering a systematic search in which the inclusion and exclusion criteria were clearly defined, it was possible to identify which implant abutment material shows the best peri-implant biological behaviour. Nine articles reporting the results of this research were identified. Conclusion: We can deduce that the most recent studies do not provide a clear indication, with regard to the biological reaction of the peri-implant tissues, as to which material is most suitable. We can conclude that zirconia is a valid alternative to titanium for creating abutments.
