1. A method for installing ceramic veneers, comprising:
isolating a surface of at least one tooth from an oral cavity; and
preparing the surface of the at least one tooth by:
sandblasting the surface of the at least one tooth with an Al2O3 oxide powder until the surface of the at least one tooth becomes uniformly rough;
after said sandblasting, etching the surface of the at least one tooth with orthophosphoric acid for 15-30 seconds;
washing and drying the surface of the at least one tooth;
uniformly applying an adhesive layer to the surface of the at least one tooth and curing the adhesive layer for 15-20 seconds;
then uniformly applying a bonding agent layer equal in thickness to the adhesive layer;
wherein the method further comprises separately preparing an inner surface of at least one veneer by:
etching the inner surface of the at least one veneer with hydrofluoric acid for one minute;
treating the inner surface of the at least one the veneer with a ceramic primer;
uniformly applying a bonding agent layer to the inner surface of the at least one veneer; and
uniformly applying a fixing composite layer to the inner surface of the at least one veneer;
wherein the at least one veneer is installed on the surface of the at least one tooth, while simultaneously performing light-curing with respect to: the adhesive layer on the surface of the at least one tooth, the bonding agent layer on the surface of the at least one tooth, the bonding agent layer and the fixing composite layer on the inner surface of the at least one veneer, wherein the light-curing begins with a luminous flux power of 100 mW/cm2 and is brought up to a luminous flux power of 500 mW/cm2 by gradually increasing it over a period of 2-10 seconds;
wherein a thickness of the bonding agent layer applied to the inner surface of the at least one veneer is equal to a thickness of the bonding agent layer applied to the surface of the at least one tooth;
and wherein a thickness of the fixing composite layer applied to the inner surface of the at least one veneer is equal to a thickness of the bonding agent layer applied to the inner surface of the at least one veneer;
and wherein until the at least one veneer is installed on the at least one tooth and said light-curing is performed, the adhesive layer and the bonding agent layer which are applied to the surface of the at least one tooth, as well as the bonding agent layer and the fixing composite layer which are applied to the inner surface of the at least one veneer are protected from intense forced and natural light radiation to avoid a pre-polymerization process.
