Abstract
Masking compositions useful for dental restoration, particularly masking compositions used as a coating to mask the unnatural color of milled lithium-silicate glass-ceramic dental restorations in soft states before crystallization cycle, and method of making same. Some embodiments relate to masking compositions comprising at least one glaze powder, at least one opacifier, and at least one colorant. Some embodiments relate to coating, drying, cooling, characterizing, and firing of dental restorations.

A method for making a coated lithium-silicate glass-ceramic dental restoration, the method comprising:
- mixing a masking composition comprising:
- at least one glaze powder;
- at least one opacifier;
- and
- at least one colorant,
- to form a paste in a soft state;
- and
- coating with the paste the lithium-silicate glass-ceramic dental restoration to form the coated lithium-silicate glass-ceramic dental restoration, wherein the opacifier and colorant are designed to disappear during a crystallization cycle.
