Thanks to an advantageous combination of chemical, biological and mechanical properties, titanium and its alloys are extensively used for manufacturing dental implants. However, studies have shown that elastic mismatch observed at the bone-implant interface could result in either stress shielding or peak stresses and subsequent reduced osseointegration. To address this, numerous works have been initiated to minimize the elastic modulus, by developing new alloy grades, low-modulus coatings, or even porous structures. Nevertheless, since isoelasticity is essentially required on surface, the present work was based on a new and original approach aiming at creating elastically graded materials. In that context, a thorough study on Ti-13Nb-13Zr alloy has been performed with respect to thermomechanical processing. It appeared that this material could display a wide variety of microstructures accompanied by a large elastic variability, ranging from 50GPa to 80GPa, making this alloy suitable to produce graded implants.
