Ceramics and Glass-Ceramics Dental Materials: Chemical Solubility, Cytotoxicity and Mechanical Properties
Abstract
<jats:p>In this work three dental ceramics were characterized according to ISO 6872: yttria-stabilized zirconia (ZrO<jats:sub>2</jats:sub>-Y<jats:sub>2</jats:sub>O<jats:sub>3</jats:sub>), lithium disilicate (Li<jats:sub>2</jats:sub>Si<jats:sub>2</jats:sub>O<jats:sub>5</jats:sub>) and the spinel-zirconia composite (MgAl<jats:sub>2</jats:sub>O<jats:sub>4</jats:sub>-ZrO<jats:sub>2</jats:sub>). The zirconia ceramic and the zirconia-spinel composite were sintered at 1600°C-2h, while the lithium disilicate was thermally treated at 820°C-20min. These materials were characterized by relative density, X-ray diffraction, scanning electron microscopy, hardness, fracture toughness, chemical solubility and cytotoxicity. The XRD results showed for the stabilized zirconia only the tetragonal phase of ZrO<jats:sub>2</jats:sub>, and to the composite only the phase MgAl<jats:sub>2</jats:sub>O<jats:sub>4</jats:sub>, Li<jats:sub>2</jats:sub>Si<jats:sub>2</jats:sub>O<jats:sub>5</jats:sub> was the only phase to lithium disilicate. Relative density results showed that the zirconia and the lithium disilicate showed high densification (> 99.5%) and the composite had a relative density of 75% (10% composite doped with ZrO<jats:sub>2</jats:sub>) and 90% (50% doped with ZrO<jats:sub>2</jats:sub>). Hardness and toughness showed 450HV and 3.2MPa.m<jats:sup>1/2</jats:sup> to ZrO<jats:sub>2</jats:sub>-MgAl<jats:sub>2</jats:sub>O<jats:sub>4</jats:sub> composites, 525HV and 1.8MPam<jats:sup>1/2</jats:sup> to lithium disilicate and 1280HV and 8.0MPa.m<jats:sup>1/2</jats:sup> to zirconia. The materials evaluated showed chemical solubility <30μg/cm<jats:sup>2</jats:sup> and the results of cytotoxicity tests indicated cell viability of the samples near 100% for all the materials, showing good chemical stability and potential for dental applications.</jats:p>
