Summary

It is believed that final glazing yields the most acceptable ceramic surfaces in terms of smoothness. However, since reglazing must be performed in a dental laboratory with the use of a thermal furnace, it requires multiple office visits. Repeated firings have a destructive effect on ceramic surfaces and can cause deformation. Conversely, polishing is easy and simple and can be accomplished in a single session.
