Introdução: O recurso a implantes dentários assumiu um papel preponderante na
reabilitação de pacientes edêntulos. O seu desempenho vai depender do tipo de
materiais, tecidos circundantes, desenho do implante e as condições do ambiente oral.
O titânio comercialmente puro é um dos materiais mais utilizado para tratamentos com
implantes devido às suas propriedades, ainda assim, também pode causar problemas.
Para procurar minorar algumas das limitações, outros materiais têm despertado a
atenção, tal como a zircônia.
O objetivo desta revisão sistemática foi avaliar a resistência à degradação e corrosão,
resposta biológica de proliferação e adesão nos tecidos peri implantares nos materiais
de titânio e zircônia.
Materiais e métodos: A pesquisa da literatura foi realizada através da bases de dados
MEDLINE (via PubMed) comparando os materias de zircônia e titânio, seguindo a
estratégia de pesquisa PICO (Participantes/População, Intervenções,
Comparação/Conteúdo, Outcome/resultados), para definir os critérios de inclusão e
critérios de exclusão.
Resultados: Em 4 dos 7 estudos incluidos confirma-se que os resultados obtidos são
mais favoráveis para o grupo de zircônia no que diz respeito ao desgaste do material e
corrosão que, por seu turno, também apresenta resposta biológicas á degradação
comparável ao material de titânio.
Conclusão: Com base nos artigos revistos pode ser constatado que os pilares de zircônia
demonstraram melhores propriedades fisico-químicas de resistência ao desgaste e
corrosão (tribocorrosão) além de melhor resposta biológica em comparação com os
pilares de titânio.
Introduction: The use of dental implants has assumed a major role in the rehabilitation of edentulous patients. Its performance will depend on the type of materials, surrounding tissues, design of the implant and the conditions of the oral environment. Commercially pure titanium is one of the most used materials for implant treatments due to its properties, yet it can also cause problems. In order to alleviate some of the limitations, other materials have attracted attention, such as zirconia. The objective of this systematic review was to evaluate the degradation and corrosion resistance and biological response of proliferation and adhesion in the peri-implant tissues of titanium and zirconia materials. Methods: The literature search was performed through the MEDLINE databases (via PubMed) comparing the materials of zirconia and titanium, following the search strategy PICO (Participants / Population, Interventions, Comparison / Content, Outcome ), for define inclusion criteria and exclusion criteria. Results: In 4 of the 7 studies included, it is confirmed that the results obtained are more favorable for the zirconia group with regard to material wear and corrosion which, in turn, also has a biological response to degradation comparable to titanium material. Conclusion: Based on the reviewed articles It can be seen that the zirconium abutments demonstrated better physico-chemical properties of resistance to wear and corrosion (tribocorrosion) in addition to a better biological response compared to titanium abutments.
