Las nanoestructuras de SLActive® aumentan el área superficial en más de un 50 %25

Incremento del área superficial del implante: +50 % más que Roxolid® SLA®.

¿Cómo maximizar la superficie del implante?

  • Una mayor área superficial en contacto con el hueso aumenta el BIC*32
  • La microrrugosidad de SLA®/SLActive® aumenta el área superficial al menos en un 100 % en comparación con la superficie mecanizada26
  • Además, las nanoestructuras aumentan el área superficial de SLActive® en más del 50 %25

*BIC = contacto hueso-implante

La investigación in vitro avanzada demuestra que las nanoestructuras favorecen una osteointegración precoz23,24

Las últimas investigaciones in vitro sugieren que la hidrofilia sola no explica completamente el proceso de osteointegración acelerado asociado con las propiedades de la superficie SLActive®. Nuevos datos indican que las nanoestructuras de la superficie SLActive® contribuyen a la formación de la red de fibrina y a la mineralización, lo cual facilita las primeras fases de la osteointegración. Efectivamente, SLActive® con nanoestructuras presenta un nivel más elevado de formación de la red de fibrina y mineralización de las células óseas en comparación con SLActive® sin nanoestructuras (in vitro).23,24
