Avaliação da dureza de diferentes metais utilizados na confecção de pinos pré-fabricados

Various types of metallic materials are being searched in the last years, suitable for the manufacture of pre-fabricated posts, aiming to be used as Intra root retainers, and aesthetic and functional restoration. You can say that despite some gains in the use of non-metallic materials for the manufacture of intra-root posts, the metal is still a highly reliable alternative, especially because the clinical performance of metal retainers has been excellent. The present study had intended to evaluate in Vickers hardness test, three different metals (C. P. Titanium, Titanium/Vanadium/Aluminum Alloy and Stainless Steel Alloy), that can be used to this end. The results obtained demonstrated significant differences among the three tested materials.
