RESUMEN

El concepto de efecto férula ha cambiado con el paso de los años, ya que con las restauraciones adhesivas se logra este efecto cuando se usan postes de fibra. La odontología mínimamente invasiva intenta un cambio en la forma de pensar y de actuar cuando se rehabilitan dientes tratados endodónticamente; se trata del respeto sistemático a las estructuras dentales, ya que ellas formarán parte del efecto férula. Para el efecto férula deberá contar por lo menos con 2 milímetros de estructura dental sana en 360^o y 1 milímetro de grosor, garantizando que la restauración protésica abrace el muñón remanente. Con suficiente efecto férula se evita la descementación de la restauración y/o la fractura radicular, garantizando el éxito de la restauración a largo plazo.
