Aging of 3Y-TZP dental zirconia and yttrium depletion

To date, stabilized zirconia is a well-established biomaterial used in dentistry. Zirconia used in dental applications is usually stabilized with 3 mol% Y2O3 (3Y-TZP) [1 –3]. The use of Y2O3 was first suggested with the addition of 2–3mol% Y2O3 resulting in materials with only the desired tetragonal crystallographic phase (t-ZrO2), called tetragonal zirconia polycrystals (TZP) [4]. The 3Y-TZP zirconia presents advanced mechanical properties as well as chemical, thermal and dimensional stability, compared to other ceramic systems.
