Abstract:
This research focused on improving the coloration of mica-based glass-ceramics for esthetics and suitability as restorative dental materials. At first, the machinable mica glass-ceramic prepared with 3.5 mol% fluorapatite was white and relatively opaque. It was derived from SiO2-Al2O3-MgO-MgF2-SrCO3-CaCO3-CaF2 and P2O5 glass system with CeO2 and Fe2O3 as pigments. In the heat treatment process to control the color of glass-ceramics, the optimum nucleation and crystallization temperatures were at 643°C and 897°C, respectively. All specimens were characterized and tested by x-ray diffraction, scanning electron microscope, biaxial flexural strength, hardness, wear rate and chemical solubility. As XRD results presented that the glassceramics with pigments possessed similar crystalline phases of phlogopite-Ca mica, fluorapatite, stishovite, anorthite and strontium apatite. From SEM analysis, it revealed the microstructures of plate-like and glass matrix in all specimens. Results of the color analysis showed that the proper amount and type of metal oxides in mica glass-ceramics improved the coloration and translucency of the glass-ceramics to close to that of natural teeth for more esthetic. The values of biaxial flexural strength were accepted according to Dentistry-Ceramic materials ISO 6872:2015 type II class 2b. The glass-ceramics could be suitable for partially or fully covered substructure ceramic for single-unit anterior or posterior prostheses adhesively cemented.
