It might be worth mentioning that in the present study materials with different elasticity modules were confronted, since titanium posts exhibited lesser rigidity than copper-aluminum posts, and were closer to a natural tooth's characteristics, this could lead to an increase in tension in the post dentin inter-phase in this latter group.
Cabe resaltar que en este estudio se confrontan materiales con módulo de elasticidad diferentes, ya que el poste en titanio tiene una rigidez menor que el de cobre aluminio y más cercana a la del diente natural, lo que podría llevar a un aumento de tensiones en la interfase poste dentina en este último grupo.
