Glazed zirconia will have significant loss to the glazed layer when enduring the day-to-day wear in the human mouth. Physiologically, when using staining & glazing kit, the fluxes in the ceramic dissolve and leave the surface similar to very abrasive sand paper causing significant wear to human enamel. As the surfaces erode, the ceramic crystal edges break and have an appearance of a file that chisels the opposing teeth. On the other hand, polished zirconia does not etch nor does the surface fracture and take on the appearance and characteristics of a file.
Before Glazing After Glazing
HaHasmile staining and glazing advantages, each bottle of stain contains glaze, no need to glaze additionally. The ideal effect can be achieved just by one-step staining, intermediate densensess and fine particles, even the beginner can learn how to use it fast and easily.
When matching color, please select main color scheme and effect shades according to proportioning table of Glaze Paste. They should be mixed in consistency as cervical color; the cervical color and transparent glaze need to be mixed to get lighter color as middle 1/3 transitional color. The following step is to mix transparent glaze with a little blue or purple-grey, the mixture can be regarded as incisal transparent effect color. The terracotta can be used as occlusal surface color. Groove can be applied color using brown. You can glaze the whole crown directly, if nowhere in the crown could be stained. Please ensure that the whole crown should be covered by the stains.
Avoid using too much paste one time, adopting principle of “take less one time, more times.” When dealing with special effect, no need to add glaze liquid. Keep original consistency to have better plasticity. For restoration that needs no staining , apply glaze directly.After the restoration is finished, please check carefully to avoid missing of coloring. After sintering, if places that are not stained or with no good color are found, sinter again after re-staining.
